Perplexity (Perplexity AI)
Quick answer
Perplexity is an AI answer engine that responds to a question with a short, sourced summary built from current web pages rather than a ranked list of links. For a brand, the question it raises is whether Perplexity's answer to a buying question names the brand at all, and which pages it draws that answer from.
Why it matters
Buyers increasingly ask Perplexity to compare tools before they visit a vendor's own site, and the engine answers with specific sources attached rather than a generic summary. A brand that never appears in that sourced answer loses a sale before a human reviewer ever sees its homepage, and the problem is invisible to normal web analytics because no click or search ever happened on the brand's own domain. Because Perplexity shows its sources, a missing or wrong mention also points at a fixable cause: either the brand is absent from the pages the engine reads, or those pages describe it in a way that does not match what buyers are asking.
How to measure it
Track a fixed set of buying questions a prospect would plausibly type into Perplexity, run them on a regular schedule, and record whether the brand appears, where it ranks against named competitors, and which sources the answer cites. MarketHQ runs this check weekly across Perplexity and five other AI engines, so a brand can see drift over time instead of a single screenshot from one day. A page that keeps getting cited, or one that never shows up, both point at a concrete next step rather than a vague sense that AI answers are a black box.
Example
A marketing team at a project-management company asks Perplexity which tools handle remote team task tracking. The answer names two competitors and cites a comparison article on a review site, but never mentions the team's own product, even though it ranks for the same search term on Google. The team checks the cited article and finds their product was launched after the article was last updated, so updating or replacing that source is the direct next step, not a general content push.
Frequently asked questions
Is Perplexity the same as a search engine?
No. A search engine returns a ranked list of links for a person to click through; Perplexity generates a direct answer with a short list of sources attached, so most people never click through at all.
Can a small brand influence what Perplexity says about it?
Yes. Perplexity's answers lean on sources it can find and read, so getting named accurately on the pages it already cites, and making sure the brand's own pages answer the exact question being asked, both change what the answer says over time.
Does MarketHQ track Perplexity alongside other AI engines?
Yes. Perplexity is one of six AI engines MarketHQ checks on a weekly run, alongside ChatGPT, Claude, Gemini, Grok and DeepSeek.
