I have a client — a mid-market professional services firm, good operational SEO, roughly 150,000 organic sessions per month at their peak in mid-2024. In March of 2026, their organic sessions are 97,000. That's a 35% decline. Their rankings haven't dropped. Their content hasn't degraded. Their domain authority hasn't fallen. The queries they rank for haven't lost search volume. They are, by every metric SEO operators traditionally care about, performing as well as they ever have.
The problem is that Google is answering the questions for them, above the blue links, in a synthesized block that cites them but no longer requires anyone to click through.
This is not a story unique to this one client. Across my book of twelve clients where I have visibility into organic traffic trends, the median drop in organic sessions from mid-2024 to early 2026 is 27%. The range is -8% (for a niche B2B SaaS with highly technical queries that AI Overviews struggle with) to -51% (for a lifestyle e-commerce brand whose top queries all trigger AI Overviews with affiliate-style answers). This is the new baseline. It is not going back.
What this actually means for paid budgets
For a decade, the marketing playbook for any mature brand has been: SEO owns the top of the funnel cheaply; paid fills the gaps, captures high-intent queries, and handles the bottom of the funnel where conversion economics work. That playbook is now, to be blunt, broken.
SEO is no longer a reliable top-of-funnel channel for most commercial queries. The queries where organic still gets meaningful click-through are the long-tail, highly specific ones that AI Overviews either don't trigger on or don't answer well. Those queries have low search volume by definition. You can't build a traffic strategy on them.
What this means tactically is that paid media is quietly absorbing the top of the funnel whether anyone has admitted it yet or not. Search Ads, Performance Max, YouTube prospecting, Meta prospecting, LinkedIn awareness — these channels are now doing work they weren't doing three years ago, because the organic counterbalance that used to exist has been eaten by generative answers.
How I'm restructuring budgets
Across the accounts I manage, here's what's changed in the last eighteen months. I'll give you rough ranges because the specifics vary by industry.
Branded search as a percent of total paid spend: down. In 2023, branded search was often 30-40% of paid spend on client accounts. Today it's typically 18-25%. Not because branded search has gotten less valuable — it hasn't — but because the rest of the account has grown, which has shifted the ratio.
Non-brand search as a percent of total paid spend: up, but also redistributed. The total non-brand search budget has increased 20-30% on average. But it's not spread evenly. It's concentrated on mid-funnel queries — the ones where users still click through because they want multiple perspectives, comparisons, or specific operator information that AI Overviews aren't great at synthesizing.
YouTube and Demand Gen as a percent of paid spend: meaningfully up. This is the big one. On the accounts where we've run this experiment rigorously, YouTube Demand Gen and View campaigns are now 12-18% of paid spend, up from 3-5% in 2023. The logic is straightforward: video surfaces are not being cannibalized by AI Overviews. YouTube search results and recommendations are a top-of-funnel environment that operates on different economics than text search, and we're moving budget to where the attention still exists.
Meta and TikTok prospecting as a percent of paid spend: up. Prospecting on social — the upper-funnel "show your brand to people who've never heard of you" motion — is more important than it was, because it's doing work that organic search is no longer doing. I've shifted 10-15% of budgets from pure retargeting toward prospecting compared to two years ago.
The measurement problem nobody's talking about
Here's the thing that's going to bite most advertisers before they notice it: when you shift spend toward top-of-funnel paid channels to replace lost organic traffic, your attribution models are going to make that spend look bad.
Last-click attribution will attribute fewer conversions to YouTube than it does to Search. Your GA4 data-driven attribution will partially correct for this, but not fully. Your MMM (if you have one) will probably show the right answer — but most mid-market brands don't have MMM.
What this means in practice: if you shift 10% of your budget from branded search to YouTube prospecting, your directly-measured ROAS will go down, even if your actual business performance goes up. You will have internal meetings where someone asks "why are we spending more on video when ROAS is lower?" The answer is "because we're replacing the organic top-of-funnel that isn't coming back." That answer is unsatisfying in a board deck. It's still correct.
This is the part of the transition that I'm spending the most time on with clients right now. Not the budget allocation itself — that's actually the easy part. It's the measurement narrative. Helping CFOs and CEOs understand that their marketing dashboards are going to look different than they did three years ago, and that "different" is not synonymous with "worse," takes a lot of hand-holding.
What to actually do
If you're running paid media inside this new reality, here are the specific things I'd tell you to check this week:
Pull your Google Search Console data for the last 24 months, segmented by query type. Look at the trend line on your impressions vs. your click-through rate. If impressions are flat or up but CTR is down, AI Overviews are eating your organic traffic. If CTR is down more than 20% on commercial queries, you are in the "lost organic top-of-funnel" situation described above, whether your marketing team has acknowledged it or not.
Audit your paid budget allocation. If you're running less than 10% of paid on video surfaces (YouTube Demand Gen, YouTube View, Meta Reels Video, TikTok), and you're in a category where AI Overviews are common, you're underweighted on top-of-funnel paid.
Review your attribution model. If you're still running "last click" attribution in GA4 or your internal BI tool, switch to data-driven attribution at minimum. If you're at the scale where MMM is economically viable (typically $3M+/year in paid media), this is the time to commission it. The measurement shift is too big to navigate by feel.
And finally: have the conversation with leadership about what "winning" looks like in a world where organic search is a smaller channel than it was. That might mean higher paid CAC that you can defend through LTV. It might mean a heavier investment in owned channels — email, community, content formats that live off-platform. But it almost certainly doesn't mean pretending SEO is still the lever it was in 2022.
This is the biggest structural shift in performance marketing since the iOS 14.5 privacy changes in 2021. It's moving slower in the press because it doesn't have a single dramatic launch event, but the cumulative impact is arguably larger. If you want someone to audit your account against this new reality, that's exactly the kind of work my audits cover. Or read my take on measurement in 2026 for the related piece on this puzzle.
