If Q2 felt like a steady climb, Q3 will look a bit different. Rather than building momentum evenly across all three months, the quarter unfolds in two phases: a quieter start followed by a much stronger finish. Looking at July alone won’t tell the full story, Q3’s momentum is expected to build significantly as the quarter progresses.

The forces driving that shift aren’t new. They’re budget planning cycles and end-of-quarter spending behavior, the same ones that have shaped every quarter in this series so far. What’s different in Q3 is a variable the first half of the year didn’t have to deal with: summer.

Here’s what that actually looks like, and how to plan around it.

Early Q3 (July): Budgets Are Fresh, Spending Is Cautious

The first few days of July often carry some residual strength from July 4th spend, then pull back once advertisers return and begin pacing fresh Q3 budgets. That early swing makes July one of the more unpredictable stretches of the quarter, and a poor benchmark for what the rest of Q3 will look like.

The quarterly reset starts after the holiday. By the time advertisers are back from the long weekend, they’ve just come out of Q2’s execution phase, and Q3 budgets are brand new. As always happens at the start of a quarter, spending starts cautiously. Teams are pacing campaigns, testing what’s working, and holding off on aggressive bids until they have more signal.

That means the back half of July is often the softest stretch of the quarter.

Late June and late July are measuring two completely different moments in the advertising cycle. One is end-of-quarter, when budgets are racing to close while the other is the beginning of a new one, when spend is just finding its footing. Comparing the two isn’t an apples-to-apples read on your performance.

Summer Introduces Real Variability

Q1 and Q2 both follow a fairly predictable rhythm. Q3 doesn’t, and that’s by design, not by accident.

Summer demand behaves differently than the rest of the year because travel picks up, outdoor and lifestyle content sees more attention, and retail moments can inject demand into the market with little warning.

That variability cuts in different directions depending on your niche. A travel or outdoor site might see a real lift in July that a different vertical doesn’t. There’s no single rule that applies evenly across every content category this quarter, which is exactly what makes Q3 harder to predict than Q1 or Q2.

You can’t run the same fixed strategy all quarter and expect it to work equally well in July as it does in September because Q3 requires you to adjust as you go.

Mid-Q3 (August): The Bridge Into Stronger Demand

August is where Q3 starts to turn. Back-to-school campaigns typically begin ramping in late July and build through August, and that spend has real momentum behind it. Unlike the cautious, wait-and-see budgets driving early July, back-to-school budgets come with a hard deadline: the school year starts whether a campaign is ready or not.

That urgency shows up in demand. For publishers in family, education, retail, and lifestyle-adjacent niches especially, August tends to outperform July, and it sets the stage for the stronger push still to come in September.

Even outside those niches, August is worth watching. It’s the bridge between July’s quiet start and September’s close, and it’s usually the first clear signal of which direction the rest of the quarter is heading.

Political Ad Spend Is a Second Demand Driver

Back-to-school isn’t the only added force pushing demand higher this quarter. Midterm election spending adds a second, and unlike back-to-school, it doesn’t wrap up when the school year starts.

Political ad spend is absorbing a growing share of linear and CTV inventory. Advertisers who can’t reach their audiences efficiently through those channels are moving budget into display and online video instead. That pressure builds through August and September and peaks in October, meaning it carries this lift past Q3 and into the start of Q4.

For publishers, that’s demand shifting in your favor. More competition for the same display and video inventory usually means better rates, though the timelines are tighter and buying behavior looks less predictable than a typical cycle.

End-of-Quarter Budgets Drive the September Push

Two forces are now stacked on top of each other heading into September. Election-driven demand is still building and the same end-of-quarter budget mechanic that made late June the strongest part of Q2. As Q3 winds down, unused budget becomes a problem advertisers actively want to solve. Spending accelerates in the final weeks of the quarter as teams push to use what they’ve allocated before it’s gone.

That means late September tends to meaningfully outperform late July.

If you’re comparing performance across the quarter, measure against the pattern. A slow start and a strong close are actually the same story, just at different points in the three-month arc.

How Publishers Can Stay Ahead of Q3 Trends

A few practical ways to work with this pattern instead of reacting to it:

• Hold your best summer content strategically. If you have strong travel, outdoor, or seasonal lifestyle content, plan for it to carry weight through the whole quarter, not just the first few weeks.
• Set realistic expectations for late July. A soft stretch after the July 4th bump is normal, not a warning sign.
• Watch for the back-to-school ramp in August. If your content touches family, education, or retail, this is often the first real sign of momentum building toward September.
• Watch for one-off demand spikes. Major retail or platform events can move the market on short notice, on top of the broader seasonal pattern.
• Keep late-September performance in perspective. It’s typically the strongest stretch of the quarter, not an outlier.

Q3 in the Context of the Advertising Year

Every quarter plays a different role in the annual cycle:

• Q1 resets budgets and strategies
• Q2 stabilizes the market and builds momentum
• Q3 introduces more variability around summer demand, building through August before the strongest activity concentrates late in the quarter
• Q4 delivers peak competition

The calendar changes every year. The behavior behind it largely doesn’t.

If you’re curious about the mechanics behind all of this, our guide on why eCPMs rise and fall throughout the year breaks down the underlying framework in more detail, and our look at the Q2 pattern covers what happens right before Q3 begins.

And if you’re evaluating whether your current ad setup is capturing this seasonal lift the way it should, Q3 is also the ideal window to make a change before Q4 arrives.

Frequently Asked Questions

Why does July feel slower than June? The very start of July often holds up thanks to July 4th spend, but the slowdown sets in once advertisers are back from the holiday and working with fresh, cautiously-paced Q3 budgets. This is the same pattern that shows up at the start of every quarter, not a sign of a problem with your site.

Is a Q3 dip normal? Yes. A softer late July is consistent with the seasonal pattern publishers see every year. What matters more than any single week is how performance trends across the full quarter.

Does August perform better than July? For many publishers, yes. Back-to-school campaigns typically start ramping in late July and build through August, giving demand a real lift ahead of the September push. Publishers in family, education, and retail-adjacent niches tend to see this most clearly.

When in Q3 should I expect the strongest performance? Late September typically outperforms the rest of the quarter, driven by advertisers spending down unused budget before the quarter closes.

Note: This piece follows the seasonality series’ standard disclaimer. Past performance can’t guarantee future results, and broader economic or market conditions can shift the pattern’s timing or intensity in a given year.

Q4 is the highest-earning quarter in digital advertising. Advertiser budgets peak, demand goes up, and CPM spikes significantly. The publishers who earn the most in Q4 are the ones who made moves in Q3, getting onboarded, optimized, and ready before the season that drives a significant portion of annual revenue.

The publishers who win Q4 aren’t just lucky with traffic. They’re with the right network. Here’s what that looks like.

What Makes Mediavine Different

Technology built and owned in-house.

Most ad networks rely on a patchwork of outside tools. Mediavine builds and maintains our own technology, including server-to-server bidding (a faster, more secure way to run ad auctions), page speed optimization, and ad placements designed to load quickly without slowing your site down. When Mediavine improves our technology, that improvement goes directly to your revenue. There is no middleman taking a cut.

99.5% human-verified inventory, independently validated by IAS, Jounce, and The Trade Desk. Zero MFA.

MFA stands for “Made for Advertising,” low-quality sites built purely to generate ad clicks, not to serve real readers. Mediavine has none of that. Every site in the network is a real publisher with real content and a real audience. That matters to advertisers, and when advertisers trust the inventory they are buying, more of them compete for your ad space. More competition means higher rates for you.

Publishers come first. Actually.

Every product decision Mediavine makes is measured against one question: does this improve publisher performance? Not advertiser convenience and definitely not the priorities of a private equity firm. We’re prioritizing publishers.

Lower ad density, better placements, faster pages.

More ads on a page does not mean more money. It usually means slower load times, a worse experience for your readers, and lower rates because advertisers pay less for cluttered inventory. Mediavine deliberately runs fewer, better ads because that is what drives revenue over the long term.

Hands-on account management.

Not a support ticket system and not a tiered response queue. Every publisher above Mediavine Official is assigned a dedicated account manager who is accountable to how your site performs.

Why Q3 Is the Right Window

During Q3, traffic is more predictable and the pressure is lower. You have time to get onboarded with a new network, get comfortable, and get your setup optimized before the season that drives a huge portion of your annual revenue.

Mediavine’s onboarding is built to get publishers up and running fast. From the moment you are approved, you have access to Mediavine’s full ad technology, a dashboard that shows you exactly what your revenue is doing and why, and for all publishers above Mediavine Official, a dedicated account manager who actually knows your site.

“Good Enough” Often Masks Real Upside

Most publishers who switch to Mediavine say the same thing: they had no idea how much money they were leaving on the table until they saw what their site could actually earn.

That is not a knock on your current ad solution. Ad management is complicated. A setup that’s been left alone for a while may seem fine, until you compare it with the results that a fully optimized setup can deliver. The difference shows up in your RPM, how often ads actually load on your pages, and how your revenue holds up when your traffic fluctuates.

If your RPM has been flat for a while, or your performance guarantee looks great for the first 90 days and a lot less great after that, those are signs something is off.

The Real Cost of Staying with the Wrong Network

Performance guarantees are one of the most common tactics competing ad networks use to attract publishers. On the surface, the offer sounds compelling. What often gets overlooked is what happens after the guarantee period ends.

The key factor is revenue share, the percentage of ad revenue you actually keep. Mediavine Premiere publishers retain 90% of the revenue their sites generate. Many competing networks retain 25%, leaving publishers with just 75%.

Consider a site earning $500,000 annually. Even with an aggressive guarantee promising a 30% revenue lift for six months, switching ad management would cost that publisher more than $112,000 over two years compared to staying with Mediavine. With a more typical guarantee, the two-year cost exceeds $135,000.

Short-term guarantees can create an initial boost, but long-term revenue share has a far greater impact on publisher earnings over time. The guarantee period is temporary. The revenue share you are left with is not.

Q3 Is the Window and Q4 Is the Payoff.

If you have been wondering whether it is time to switch, the answer is yes, and the time is now. You still have the runway to do it right, get set up, get optimized, and go into Q4 ready.

Many publishers see that their Monetized RPM (mRPM) is higher than their standard RPM and stop there. But comparing the two can reveal valuable insights. The gap between those two numbers is actually telling you something, and the publishers who learn to read it will optimize their revenue in ways that were never possible with standard RPM.

Here’s how to use both together to your advantage.

Start With the Gap

Your standard RPM counts every session. Your mRPM counts only the sessions where ads were able to serve, meaning sessions where ads had a real chance to load and generate revenue. The difference between those two numbers tells you how much of your traffic is not fully monetizable.

A big gap means a significant portion of your sessions are unmonetizable. A small gap means most of your traffic is ad-eligible. That gap varies widely depending on your traffic sources, the countries your readers come from, and how your consent management platform is set up. The most common reasons sessions go unmonetized include:

• Traffic from regions with low or no advertiser demand
• Invalid or non-human traffic, including AI bot crawlers
• Privacy consent restrictions
• Content category restrictions implemented on the advertiser side
• Ad blockers

Neither end of that range is inherently good or bad. It’s simply your starting point and it shapes every other decision below.

1. Which Pages Are Actually Making You Money?

Traffic volume and monetization value are not always aligned. A post driving 50,000 sessions can earn less than a post driving 10,000 sessions, depending on the quality of that traffic. mRPM makes that visible.

In your Mediavine dashboard, look at mRPM alongside monetizable session volume at the page level.

High mRPM + high sessions

Your strongest pages. Advertisers are competing for this audience and paying for it. Update the content, build related posts, and drive more traffic here. More sessions on these pages have direct revenue impact.

Low mRPM + high sessions

Traffic is there, revenue isn’t. There are a number of reasons this can happen, like geographic, source-based, or technical. Identify the root cause before investing further.

Low mRPM + low sessions

These pages are neither driving traffic nor earning revenue. Audit them, update them, consolidate them, or redirect traffic to stronger pages.

High mRPM + low sessions

These pages monetize well but aren’t reaching enough people. Advertiser demand exists. The opportunity is building an audience for it. Prioritize SEO, internal linking, and related content to grow sessions here.

2. Where Is Your Traffic Actually Coming From?

Some channels consistently deliver readers who monetize more efficiently. Others just inflate your session count. Now you can tell the difference.

Look at your traffic sources, search, social, direct, referral, and compare the percentage of sessions from each source where ads actually served. The sources with strong rates are where your time pays off. The ones with low rates are worth a harder look before you put more effort into them.

Social traffic often skews lower here, but that doesn’t mean it’s worthless. It drives audience growth and brand visibility. Knowing the trade-off means you can make an intentional decision about it rather than just wondering why your numbers look the way they do.

3. Geography Matters More Than You Might Think

Advertisers bid more aggressively in certain markets, primarily the United States, United Kingdom, Canada, and Australia. In other regions, fewer advertisers compete for your inventory, which means lower rates and fewer monetizable sessions.

If a significant share of your readers come from lower-demand regions, your monetizable session percentage will reflect that. Use that data to guide your content and SEO focus over time. Topics with strong search volume in high-demand markets will consistently monetize better than topics that primarily attract audiences from lower-demand regions.

This isn’t an overnight fix. But tracking your geographic monetizable session percentage over time will show you whether your efforts are moving in the right direction.

4. When Your Revenue Shifts, Here’s How to Diagnose It

See a boost or drop in RPM? Typically, publishers guess at why but mRPM removes some of that guesswork.

When your revenue shifts in either direction, compare standard RPM against mRPM. Two scenarios tell you two very different things.

Standard RPM shifted but mRPM held steady. 

Your monetization is working fine. The change is a traffic quality issue, more or fewer unmonetizable sessions coming in from a new source, a viral post that attracted bot traffic, or a seasonal influx from a lower-demand region. The issue may be more related to traffic quality than ad strategy. It is a traffic source audit.

Both standard RPM and mRPM shifted. 

This points to an actual monetization issue, like advertiser demand, ad strategy, viewability, or audience engagement. A boost here means your ad setup and content are firing on all cylinders. A drop is worth digging into and worth a conversation with your Account Manager.

Knowing which scenario you are in saves you from making the wrong fix. Changing your content strategy in response to a traffic quality problem solves nothing. And celebrating a traffic win when your monetization is actually what improved? That’s worth knowing too.

5. Use Both Numbers

Standard RPM and mRPM aren’t in competition. They’re two parts of the same picture.

Standard RPM reflects how your overall site is performing. It includes every session, monetizable or not. It’s your broadest view of growth. mRPM shows how your advertising is actually performing on the sessions where it had a real chance. It’s your measure of monetization efficiency.

Setting performance goals against standard RPM alone means measuring yourself against sessions that could never contribute to revenue. That’s not a useful benchmark for ad performance. But dropping standard RPM entirely means losing sight of how your overall audience is growing.

Keep both in view. Track your monetizable session percentage separately and watch it move over time as your traffic quality improves. Monitoring both gives you the full story.

Where to Start

Log into your Mediavine dashboard and pull your page-level data. The gap between your highest and lowest mRPM pages is where the clearest opportunities will show up. Start there, find the pattern, and build your strategy from what you uncover.

At Mediavine, advertising can do more than drive revenue. At its best, advertising creates opportunity, amplifies voices, and builds a more inclusive publishing industry.

With this in mind, we introduced Uplift by Mediavine back in 2023. Uplift connects advertisers with publishers from underrepresented communities and seeks to create more equitable opportunities across the advertising landscape.

Since launching Uplift by Mediavine, we’ve partnered with Sertify to offer third-party certification for diversely owned publishers, making it easier for them to verify their business identity with brands actively seeking to diversify their media spend.

What Is Uplift by Mediavine?

Uplift by Mediavine is Mediavine’s dedicated diversity marketplace, connecting advertisers with publishers from underrepresented communities so every ad dollar becomes a force for equity.

Through Uplift, brands can direct ad spend toward publishers who identify as:

• Women-owned
• LGBTQIA+ owned
• Black-owned
• Hispanic-owned
• Asian-owned
• Veteran-owned
• Disability-owned
• And other historically underrepresented groups

Through Uplift by Mediavine, we create a more inclusive advertising ecosystem where diverse publishers have greater access to premium advertising opportunities. Publishers from these communities can join Uplift to gain increased visibility with advertisers who prioritize inclusive media buying. On the brand side, Uplift by Mediavine creates a trusted way to support underrepresented publishers while reaching highly engaged audiences.

Introducing Sertify Verification

Sertify is a certification platform that verifies diverse ownership across a range of traditionally underrepresented groups, making it easier for brands to direct media spend intentionally and connect with publishers aligned with their diversity initiatives.

Through partnering with Sertify, Uplift by Mediavine makes it easier for advertisers to confidently invest in diverse-owned publishers and helps publishers gain greater visibility in inclusive advertising campaigns.

By joining together, the Uplift by Mediavine and Sertify partnership creates a more accessible pathway between brands looking to diversify their media spend and publishers looking to grow within a premium advertising ecosystem.

Why Should You Identify As Diverse-Owned, If Eligible

For publishers, self-identifying through Uplift and Sertify as a diverse-owned business (if you identify as part of a community that is historically underrepresented) offers several important benefits to your site:

Gain Additional Credibility

Certification helps brands confidently identify and support diverse-owned businesses, building a trusted standard across the publishing landscape.

Connect With Advertisers Prioritizing Inclusion

Advertisers actively seek verified diverse-owned businesses when planning campaigns and allocating budget. Participation in Uplift allows publishers to stand out during the planning and allocation process, making them frontrunners in those conversations.

A Premium Advertising Ecosystem

Uplift is built into Mediavine’s existing advertising marketplace, meaning publishers continue benefiting from premium demand, strong user experience standards, and high-quality advertising partners.

Simple Setup

Eligible publishers can enable Uplift by Mediavine from their dashboard, and start the Sertify certification application process on the same page. Once enabled, Mediavine handles the operational side of connecting eligible publishers with participating advertisers. We’ll handle conversations and negotiations with advertisers on your behalf. 

How to Self-Identify through Uplift and Sertify

Getting started is simple:

1. Log into your Mediavine Dashboard

4. Click over to Sertify’s website to apply for certification

Once you’ve opted into Uplift and self-identified, your site can be matched with campaigns specifically designed to support diverse-owned publishers.

Building a More Inclusive Future for Advertising

Advertising shapes culture, and the publishers that brands choose to support directly influence what audiences see online. At the same time, diverse-owned businesses have historically been underrepresented in media buying despite building highly engaged communities and producing exceptional content.

At Mediavine, great advertising does more than monetize content. It supports publishers, strengthens communities, and creates opportunities for voices that deserve greater visibility. Uplift helps bridge that gap by making it easier for advertisers to discover and invest in diverse publishers at scale, while Sertify certification bolsters meaningful connections between brands and publishers.

Since Uplift is built directly into Mediavine’s premium advertising landspace, participation is seamless for publishers already monetizing with Mediavine. Self-identify today to start connecting with advertisers who want to amplify your voice and boost your revenue opportunities.

If you’ve ever looked at your RPM and thought “that doesn’t feel quite right,” you’re probably on to something.

RPM, or revenue per mille, measures how much revenue you earn per thousand sessions. It’s one of the most-watched numbers in a publisher’s dashboard, the gut-check metric, the one you scan first thing in the morning and bring up in every performance conversation. But the way it’s traditionally calculated has a flaw baked in, and it’s one the industry has largely just accepted.

Here’s the issue: standard GA RPM divides your revenue by all of your sessions. Every single one. The human visits, the bot traffic, the ad-blocked sessions, the visits where no ad could ever have served. All of that non-monetizable traffic sits in the denominator, dragging your RPM down and making your revenue performance look worse than it actually is.

Think of it this way: if you ran a coffee shop, you wouldn’t measure sales per customer by counting everyone who walked past the window. You’d count the people who actually came inside. GA RPM is counting the window-shoppers.

You’re not seeing how your monetizable traffic is truly performing. You’re seeing it diluted by traffic that was never going to generate revenue.

Why This Matters More Than You Might Think

The distortion isn’t just a reporting inconvenience. It affects real decisions. When you test a new ad layout, shift your content strategy, or try to understand why revenue moved in a given week, you’re making those calls against a metric that lumps your actual ad-eligible audience in with traffic that was never in play. That makes it genuinely harder to know what’s working, and what isn’t.

It also makes comparisons unreliable. Two sites with identical monetized performance can show very different RPMs depending on how much non-monetizable traffic each one carries. The number looks objective. The comparison rarely is.

What a Cleaner Signal Looks Like

The fix is straightforward: measure revenue against the traffic that can actually generate it: monetizable sessions only.

When you do that, things get sharper in ways that matter:

• Testing becomes more useful. Layout changes, content strategies, or audience experiments that looked inconclusive against a noisy metric are easier to read when the signal is clean.
• Trends are easier to trust. Revenue movement that looked flat can show real growth once you remove traffic that was never going to convert.
• Decisions become more informed. Whether you’re thinking about ad placement, content investment, or audience growth, you’re working from numbers that reflect reality.

Your RPM should tell you what your audience is actually worth to advertisers. Not a diluted average that includes visitors who were never going to see an ad.

The Metric You Use Shapes Every Decision You Make

When testing, optimization, and growth strategy all run through RPM, the quality of that number matters. A diluted signal doesn’t just make reporting harder to read. It makes it harder to know what’s actually working. Publishers who understand how their metrics are calculated, and demand better ones, will make sharper decisions and have a clearer picture of where their business actually stands.

That starts with asking a better question: not just what your RPM is, but exactly what it’s measuring.

At Mediavine, this is exactly the problem we’ve been working to solve.
