How to do a free SEO competitor analysis, step by step

Your SEO competitors are the sites that rank for the queries you want, which may not be your business competitors. Take twenty queries from Search Console where you appear between positions 5 and 40, search each, and note the domains that appear repeatedly on page one. The three to five that recur are your competitor set. Include one site that is clearly larger than you; the gap it reveals is your roadmap even if you cannot close it this quarter.

Fetch each competitor's sitemap at /sitemap.xml or from their robots.txt, or crawl the site with a free crawler capped at a few hundred URLs. Group their URLs by path pattern: /blog/, /compare/, /alternatives/, /tools/, /templates/, /integrations/, and so on. Do the same for your site. The comparison usually shows a whole page type you lack, such as comparison pages or free tools, before it shows any keyword gap. That is the highest-value finding because one page type can represent dozens of pages.

Export 90 days of queries from Search Console with impressions and position. This is the one dataset no competitor has. For each query where you rank between 11 and 40, search it and record which competitor page ranks above you and what type of page it is. Patterns emerge quickly: a competitor's comparison page beating your blog post, or a competitor's dedicated tool page beating your general feature page. Each pattern is a page to build or restructure.

A free competitor analysis tool can speed this up by comparing two URLs or domains on visible content, headings, and structured data. SerionFlow's free SEO competitor analysis tool does this without an account.

Open the competitor pages that beat you and note the structure: word count, number of H2 sections, presence of a direct answer near the top, tables, FAQ sections, schema types, internal links to related pages, and how recently the page was updated. Fetch the page with JavaScript disabled to see what a crawler sees. The structural gaps are often larger than the content gaps and are cheaper to close.

Compare robots.txt, sitemap validity, canonical handling, title and meta description quality, and page speed on the pages that compete directly. Free checkers exist for each of these. Technical parity rarely wins on its own, but a technical deficit can neutralise a content advantage, and it is the cheapest category to fix.

List every page or page type the analysis surfaced, score each by the impressions you already have for related queries, the competitor's position, and the effort to build, and sort. Build from the top. Re-run the analysis quarterly, since competitor sets shift. Teams that want this loop automated can use a platform that studies competitor domains and Search Console together; SerionFlow's opportunity map is built from exactly these inputs and proposes pages ranked by evidence.
