Sixty percent of citations on AI search engine Perplexity overlap with the top 10 Google organic search results, according to a new analysis.
- Healthcare had the highest result overlap – 82%. Both Perplexity and Google cite authoritative sites like the Mayo Clinic and the National Institutes of Health.
- Restaurants had the lowest overlap – 27%.
Why we care. This finding may seem a bit surprising considering an analysis that found 94% of Google Search Generative Experience links are different from its own organic results. But it’s also good news that if you’ve prioritized SEO for Google and have focused on building a notable brand, you should be off to a good start on optimizing for Perplexity.
