Should I stop using Google?

No, but you should stop using Google for questions where you want a synthesized answer instead of a list of links. Google AI Overviews now appear on ~48% of queries and handle the "what is X" job well enough; for deeper synthesis with sources you want, Perplexity is the better tool.

Which is most reliable on citations?

Perplexity — by a clear margin. It's designed citation-first. ChatGPT search has improved a lot but still occasionally cites a source that contradicts the claim. Google AI Overviews cite well-ranked pages, which doesn't always mean accurate ones.

Will AI Overviews kill SEO?

It's reshaping it, not killing it. ~97% of Overview citations come from pages that already rank in the top 20 organically — meaning traditional SEO is the prerequisite for AI visibility, not its replacement.

Perplexity vs ChatGPT search vs Google AI Overviews

Three different products now compete for the "search the web and synthesize an answer" job: Perplexity, ChatGPT search, and Google AI Overviews. They look similar at a glance — type a question, get a written answer with citations — but they're shaped by very different defaults. We compared all three on the same ten research questions and scored them on citation accuracy, source quality, recency, and the workflow around the answer. Here's where each one actually wins.

The three approaches

Perplexity is search-first. The default UI is a search box; the model is invisible (it picks one for you). Citations are first-class — every claim has an inline footnote linking to its source.

ChatGPT search is chat-first with search bolted on. You start in a chat; when the model decides browsing is needed (or you ask explicitly), it runs searches and synthesizes. Citations appear but are less prominent than Perplexity's.

Google AI Overviews is the result-page summary that appears above the blue links on ~48% of queries. You don't ask for it; Google decides whether to surface one. Citations exist (as link chips) but compete for attention with the rest of the SERP.

How they scored (ten queries)

Criterion	Perplexity	ChatGPT search	Google AI Overviews
Citation accuracy (claim-to-source match)	9/10	7/10	8/10
Source diversity (not just top 3 results)	8/10	6/10	5/10
Recency (within 30 days)	9/10	8/10	9/10
Multi-step follow-ups	8/10	9/10	4/10
Mobile experience	8/10	7/10	9/10

Perplexity wins on the criteria that matter for actual research (citation accuracy, source diversity). ChatGPT search wins on follow-up depth — you can dig further from the same conversation. AI Overviews wins on mobile (it's just there, no app needed) and recency.

Which one to use when

Use Perplexity when you're researching and you'll cite the result. The citation discipline is real and the source diversity beats the others. Free tier is generous; Pro adds better models and longer answers.

Use ChatGPT search when you're in the middle of a longer task and want a "while I'm at it" research step. The fact that it lives inside a chat means you can ask follow-ups against the same context — useful when research is one step of a bigger workflow.

Use Google AI Overviews for quick questions on the go. Don't trust them blindly; the citation rigor isn't as strong as Perplexity, but for "what year did X release" type questions they're fast and usually right.

The meta-takeaway for content creators

If you write content that's expected to rank in the AI Overviews era: structure your posts so the first 150-200 words are a complete answer to the primary query. Per the citation data, AI Overviews pull from pages that already rank top-20 — so traditional on-page SEO still matters, but the new constraint is that your TL;DR has to be quotable on its own. This is exactly the discipline we apply across this blog (see our editorial workflow for the lint rules that enforce it).
