ChatGPT vs Perplexity vs Google AI Overviews: Marketer's Guide

Three AI search platforms, three different algorithms, three different optimization strategies. Here's what you need to do to appear in all three.

Three platforms, three ways of deciding who gets cited. Optimise for one and you lose the other two.

Google AI Overviews

Summarises pages that already rank well. The correlation with classic positions is strong — if you're not on page one, your odds of appearing in the summary are slim.

Google states plainly that no special markup is needed: same ranking systems, same signals. Which means the work for AI Overviews is largely classic SEO done properly.

One thing worth knowing: Google generates related queries in the background and synthesises across all of them. So covering a whole topic matters more than one page per keyword.

Perplexity

Always cites, with visible links. It favours recent, authoritative, well-structured sources — and it's the most open of the three to pages that aren't ranked first.

This is where structure matters most. Comparison tables, numbered lists, short definitions at the top of a section: all of them raise your odds of extraction.

ChatGPT

Draws from a much wider pool than Google's top results. Wikipedia accounts for close to 8% of citations, Reddit around 1.8%.

That makes it the platform where presence off your own site weighs heaviest. A good Reddit thread or an accurate Wikipedia page can matter more than your entire blog.

What to do about it

Not three strategies, but one with three layers:

  1. Healthy SEO — clean indexing, speed, content that deserves to rank. Without it you don't exist in AI Overviews.
  2. Extractable structure — 40–60 word answers at the top of sections, tables for comparisons, a real FAQ. This is what wins Perplexity.
  3. Third-party presence — mentions, comparisons, reviews, communities. This is what wins ChatGPT.

How to measure

There's no Search Console report for this. The method that works is manual: 15–20 representative questions, asked monthly across all three, recording who gets cited. It's crude, but it's the only thing that tells you whether you're moving.
