Competitor research tools

Tools that estimate another site's organic traffic, the keywords it ranks for, its top pages and its ad spend. All of it is modelled from rankings and click-through curves, so treat the numbers as relative, not exact.

Buyer's guide

How to choose competitor research tools

Competitor research tools estimate what another site gets from search: its organic traffic, the keywords it ranks for, its best pages, its backlinks and, in some tools, its ad spend. None of this comes from the competitor. It is modelled from rankings, estimated search volumes and click-through curves, which is why two tools can disagree by a factor of two about the same domain. Use the figures to compare sites with each other inside one tool, not as anyone's real traffic.

Suites that answer most questions

The big SEO suites cover competitor research as one part of a wider kit. Ahrefs starts at $29 a month, SpyFu at $39, Serpstat at $69 and Semrush at $139, and SE Ranking's core plan is €109. SpyFu pairs the organic data with the Google Ads keywords competitors buy and their ad history. If you already pay for one of these, you probably already have the reports you need.

Traffic and market tools

Similarweb estimates total visits from all channels, not just search, and starts at $199 a month for 1 user and 3 months of history. That makes it the tool for questions like "how big is this competitor overall" rather than "which keywords do they win".

Free ways in

Browser extensions put competitor metrics on the page you are looking at. SEOquake is free, and a free Semrush account adds Authority Score and referring domains. The Ahrefs SEO Toolbar shows Domain Rating and URL Rating after a free sign-in. Wappalyzer shows what a competitor's site is built with.

How to choose

The question you ask most often. Keyword gaps, top pages, links and paid search are each a different strength.
Database coverage in your market. Estimates outside the largest markets rest on thinner data.
History. Seeing how a competitor grew over two years is worth more than a single snapshot. Check how far back each plan goes.
