Why did paid search growth slow in Q2 2026?

Growth slowed mainly because Q2 2025 was a strong comparable period, not because demand fell. Google paid search still grew 14% YoY in clicks, which is healthy by any standard.

What is match rate and why does it matter for Meta and Google campaigns?

Match rate is the percentage of your uploaded audience that a platform can actually identify and target. Most brands sit at 40, 60%, meaning a large share of their retargeting list never sees an ad.

How are AI Overviews affecting paid search budgets?

AI Overviews have cut organic CTR for top positions by up to 58% according to Ahrefs. That pushes paid search from a supplementary channel to a baseline one, which changes how you should plan budgets.

Are Meta Advantage+ campaigns worth the higher CPMs?

Advantage+ campaigns are running at a 75 billion USD annual run-rate, with Meta reporting +8% click lift and +15.7% more conversions. The higher CPMs are manageable if your match rate and landing pages are in good shape.

Meta Ads & paid search: Q2 2026 reality check

Paid search growth slowed in Q2 2026, but demand did not fall. The main culprit is a tough comparable period from Q2 2025, which was itself a strong quarter. What makes this moment worth paying attention to is that three separate problems are hitting campaign performance at the same time: AI Overviews are gutting organic traffic, Meta ad prices are climbing, and a low match rate is quietly draining retargeting budgets.

Key takeaways

Google paid search grew 14% YoY in clicks, Google Shopping +18%, YouTube +15%, Instagram +17% (Search Engine Journal).
AI Overviews cut organic CTR for top positions by 58% (Ahrefs, via SEJ) - paid search is now a baseline channel, not a backup.
Meta Advantage+ is running at a 75 billion USD annual run-rate, but ad prices rose 12% in Q2 (AdWeek).
Most brands have a match rate of 40-60%, meaning retargeting is running at less than half capacity (Marketing Land).
Low match rates on suppression lists mean you are paying acquisition prices to reach your own existing customers.

Q2 slowed down - read the numbers in context

Search Engine Journal points out that Q2 2025 was a genuinely strong quarter, so the lower YoY growth rate in Q2 2026 is largely a math problem, not a demand signal. Google Shopping at +18% and Instagram at +17% are still healthy. Amazon Sponsored Products posted +38%, but strip out the Prime Day calendar shift from July to June and the real number is closer to +23%. In Q3 2026 the Amazon comparable will be tougher, so softer numbers there will not mean weak demand either.

The practical point: do not use platform-level averages as planning targets. Break your own account down by impression share, marginal CPA/ROAS, search query coverage and auction insights. Growth potential now varies significantly from account to account.

AI Overviews have changed what paid search is for

Organic CTR for the top position has dropped 58% (Ahrefs). Pew Research data shows pages with AI Overviews getting 8% CTR versus 15% without them. This is not just an SEO problem. If your planning model assumed organic would carry some demand and paid search would supplement it, that model no longer holds.

Paid search is now the primary demand capture channel for most categories. H2 budgets need to be planned that way, not as a safety net for organic. If you want to see how this plays out across channels, Charlie's product is built around exactly this kind of cross-channel planning.

Meta: higher prices, higher performance - if you know what you are doing

Meta reported record ad revenue of 59.36 billion USD in Q2 2025, up 28% YoY. Ad prices rose 12%, impressions rose 14%. AdWeek also reports that AI ad targeting delivers a +8% click lift and +15.7% more Facebook conversions. Advantage+ campaigns are running at a 75 billion USD annual run-rate.

Higher CPM is not just a cost increase - it is the entry price for auctions where Meta's algorithm is genuinely working. At the same time, Search Engine Land reports that Meta's live shopping ads and virtual card checkout reduce abandonment rates by up to 30% by eliminating redirects to external sites. For e-commerce clients, this is a format worth testing now rather than in six months.

What to actually do with your Meta budget

Shift more spend toward Advantage+ and away from manual targeting - the data shows the algorithm scales better.
Test the live shopping format while Meta is actively promoting it and giving it preferential reach.
Integrate virtual checkout into remarketing flows to cut friction at the point of conversion.

Match rate: the number nobody tracks but that wrecks ROAS

Marketing Land describes the case of CKE Restaurants (Carl's Jr., Hardee's), where simply enriching audience identifiers increased match rate by 117% on Google Ads and 29% on Meta, with no budget or creative changes. ROAS improved on the same spend.

Most brands upload email lists with a 40-60% match rate. At 45% match rate, your retargeting program is running at under half capacity. The platform reports great numbers because it only measures the matched portion - but you are paying for the whole list.

The suppression list problem is even more expensive. Every existing customer the platform fails to recognize gets served an acquisition ad, sometimes including a new-customer discount. You are paying to re-acquire people who already bought from you.

This is not a three-month project to fix. Identifier enrichment happens at the point of sending the audience to the platform, as a connector configuration. Check your match rate today: compare the size of the list you uploaded against the audience size the platform actually matched. Both Google Ads and Meta report this number.

Landing pages as the silent conversion killer

Semrush Blog makes a point that gets lost in conversations about AI bidding and audience strategy: Google explicitly states that poor landing page navigation reduces ad visibility and raises CPC. When CPMs are rising on both Meta and Google, this is exactly the detail that determines whether a campaign is profitable or not.

Specific steps: remove navigation from landing pages (keep only privacy and terms links), rewrite CTAs in first person ("Start my free trial" rather than "Submit"), and place CTAs both above the fold and at natural stopping points on longer pages. A/B test headline angles across problem-based, aspirational, value-based and identity-focused framings.

If you want visibility across all of these variables in one place, Charlie's 43 AI specialists cover everything from landing page optimization to auction insight analysis.

How to read this together

Paid search slowed but demand did not drop. Meta is more expensive but performs better - if your match rate and landing pages are in order. AI Overviews have moved paid search from supplementary to foundational. And match rate is probably a number you do not know right now, and it is quietly reducing the performance of everything else.

H2 planning does not rest on platform averages. It rests on four specific numbers: match rate, impression share, marginal CPA, and landing page conversion rate. Start there.
