Should I still focus on Google SEO or AI search? The honest answer is both, but not in equal measure. Organic clicks on AI Overview queries fell to a low of 1.3% in December 2025, then recovered to 2.4% by February 2026. This guide separates what the data shows from what it means for your budget, and where answer engine optimization changes the work.
Quick answer
Yes. Google describes optimizing for generative AI search as still SEO, and a page must be indexed and eligible for ordinary search before it can be cited in AI Overviews or AI Mode. Investment should shift toward pages that earn citations, not just clicks.

Does SEO still pay off when AI answers appear before the links?
Yes, but the payoff has shifted from clicks toward being cited. According to Peaceful Media, Google describes optimizing for generative AI search as still SEO. A page must first be indexed and eligible for ordinary Google Search before it can appear in AI Overviews or AI Mode. Traditional rankings therefore remain the entry ticket. The mistake is treating a ranking as the finish line, because a top result no longer guarantees a visit. According to Similarweb's clickstream data (cited in Peaceful Media), 68% of Google searches end without a click to any website. The working question for a marketing team is which pages still earn a click and which earn a citation that shapes the buyer before any click happens.
should i still focus on google seo or ai search — by the numbers
How far have click-through rates actually fallen?
The decline is real but it is not uniform. According to Ahrefs, an AI Overview correlated with a 34.5% lower average click-through rate for the top-ranking page across 300,000 keywords. Pew Research Center found that users clicked a traditional result on 8% of pages with an AI summary.
However, the trend is changing. According to Seer Interactive, organic click-through on AI Overview queries fell for eighteen straight months. It reached 1.3% in December 2025, then recovered to 2.4% by February 2026. Specifically, queries without an AI Overview rose from 2.8% to 3.8% over the same period.
- Treat AI-answered and clean queries as separate planning groups.
- Track the gap between the two query types over time.
- Review click-through rates before changing content strategy.
How do Google AI Overviews, ChatGPT, and Perplexity pick their sources?
Each engine draws on the open web, but they reward different signals. AI Overviews sit on top of Google's existing index, so eligibility depends on classic indexation and ranking. ChatGPT and Perplexity retrieve external pages and favour clear entities, direct answers, and sources they can verify. According to Peaceful Media's summary of Semrush and Smith Digital observations, AI platforms still rely on crawlability, topical focus, entity clarity, authoritative content, and off-site validation. A ranking in Google therefore does not transfer automatically to Perplexity, and a brand cited in ChatGPT may be absent from Google's AI Overview for the same query.
| Engine | Primary source pool | What tends to earn the citation |
|---|---|---|
| Google AI Overviews | Google's indexed web | Indexation, ranking, entity clarity |
| ChatGPT | External retrieved pages | Direct answers, verifiable sources |
| Perplexity | External retrieved pages | Explicit citations, topical focus |
Platform behaviour changes often. Verify citation patterns in your own category before committing budget.
What carries over from SEO, and what changes in content format?
Crawlability, indexation, internal linking, and topical authority carry over almost intact. What changes is the unit of value. Traditional pages were built to rank for a keyword and hold a reader; answer-first pages are built so a passage can be lifted intact. Lead each section with a direct answer, keep entity names explicit, and use headings that match real questions. Structured data and llms.txt help agents parse the page, but they do not substitute for a page that a search engine can index in the first place.
- Keep the answer in the first two sentences of each section.
- Name the tools, companies, and standards precisely.
- Make sure every page is indexable before optimizing its format.
Where ranking well still falls short
Ranking first on Google no longer guarantees traffic. According to a 2026 Schwartz Marketing Lab study, reported by PR Newswire, ranking No. 1 does not secure visits when an AI answer sits above the results. Treat search rank as a precondition and AI citation as a separate metric. A page can hold position one and still be absent from the answer a buyer reads. According to Ahrefs' analysis of 300,000 keywords, the presence of an AI Overview correlated with a 34.5% lower average click-through rate for the top-ranking page. This is why a brand can look healthy in rank reports while losing the consideration stage. Tracking both rank and citation gives marketing teams a clearer view of where visibility is actually earned.
How should you measure performance across both channels?
Measuring performance across both channels means tracking two scorecards in parallel rather than blending them. The traditional scorecard covers rankings, impressions, organic clicks, and conversions from Google. The AI scorecard covers how often your brand is cited, for which queries, on which engines, and what the citing passage says. Citation Analytics across ChatGPT, Perplexity, Gemini, and Google AI Overviews can show where your brand appears in AI answers. Brand Memory can keep the facts those engines read accurate.
However, effort should be allocated by query type. Prioritise Google SEO for queries with no AI Overview and high click yield. Invest in citation-ready pages for AI-answered queries where the buyer decides before clicking.

Frequently asked questions
Is SEO still worth investing in if AI answers appear before the links?
Yes. Google describes optimizing for generative AI search as still SEO, and a page must be indexed and eligible for ordinary search before it can be cited in AI Overviews or AI Mode. Investment should shift toward pages that earn citations, not just clicks.
How much have click-through rates dropped since AI Overviews launched?
According to Ahrefs' analysis of 300,000 keywords, an AI Overview correlated with a 34.5% lower average click-through rate for the top-ranking page. Specifically, Seer Interactive reported that AI Overview queries bottomed at 1.3% in December 2025. However, they recovered to 2.4% by February 2026.
Is the click decline recovering?
Partly. According to Seer Interactive's 2026 study of 53 brands, organic click-through on AI Overview queries recovered to 2.4% by February 2026. Meanwhile, queries without an AI Overview rose from 2.8% to 3.8%. Specifically, the gap between the two query types is still widening.
Does ranking first on Google guarantee visibility in ChatGPT or Perplexity?
No. Each engine retrieves and weighs sources differently. A page that ranks well in Google may still be absent from Perplexity or ChatGPT answers. Citation presence should therefore be tracked on each engine separately, using Citation Analytics across ChatGPT, Perplexity, Gemini, and Google AI Overviews.
What SEO foundations carry over to AI search?
Crawlability, indexation, topical focus, entity clarity, authoritative content, and off-site validation carry over. According to observations summarised by Peaceful Media from Semrush and Smith Digital, these factors still determine AI eligibility. However, the format changes. Specifically, answer-first sections are built so a passage can be quoted from intact.
How do Google AI Overviews differ from ChatGPT and Perplexity in citing sources?
AI Overviews sit on Google's existing index, so classic ranking and indexation drive eligibility. However, ChatGPT and Perplexity retrieve external pages. Specifically, they favour direct answers and verifiable sources. As a result, the same query can produce different cited brands across these engines.
How should I measure AI search visibility separately from rankings?
Run two scorecards. Track rankings, impressions, and organic clicks for Google, and track citation frequency, query coverage, and cited passages for AI engines. Citation Analytics across ChatGPT, Perplexity, Gemini, and Google AI Overviews can report the second set in one view.
Where should a marketing team start if the budget is limited?
Start with an audit of which queries trigger AI Overviews and which still deliver clicks. According to Engain, AI Overview coverage of queries is roughly 30% to 48%, so the audit matters. Keep traditional SEO on queries that still yield clicks. Build answer-first pages for the AI-answered queries where buyers decide before clicking. Make sure every target page is indexable first. Otherwise, it cannot be cited in AI Overviews or AI Mode.
