How to compare two websites' SEO
Enter your URL and a competitor's URL above, then hit Compare. The tool runs a full SEO audit on each site and lines the results up side by side: an overall score, then a check-by-check breakdown covering title tags, meta descriptions, heading structure, HTTPS, robots.txt, XML sitemaps, Open Graph tags and canonicals.
The point of a website SEO comparison isn't the score itself - it's the delta. If a competitor outranks you, the checks they pass that you fail are the shortest fix list you'll get. And if you outscore them technically but still rank below them, you've learned something too: your gap is content or authority, not technical SEO - stop tweaking tags and go write the better page.
Comparing more than two? Add up to 5 URLs to benchmark a whole niche in one run - useful before entering a market or pitching an SEO client. Pitching one? Send them a free client SEO report of their own site to go with it. For a deeper look at any single site afterwards, run the full free SEO audit, check how its snippet renders in the SERP preview tool, or read our guide to what each audit check actually means.
Technical checks are one side of a website SEO comparison. Authority is the other: compare backlink strength for up to 10 domains at once with the free Domain Rating checker. For a step-by-step method, see how to compare two websites' SEO.
SEO comparison tool: compare websites' SEO side by side
To compare websites' SEO, run the same audit on each site at the same moment and read the results side by side. This SEO comparison tool does that for up to 5 URLs: it scores each page out of 100 and lines up 40+ checks, so you see exactly where one site is ahead.
What a website SEO comparison can't tell you
An on-page comparison covers what is on the page: titles, headings, schema, speed, links. It doesn't cover the two things that often decide who ranks: how many sites link to each one, and how well each page answers the search.
For links, compare both domains in the Domain Rating checker. For the content, read the pages that rank first for your search and note what they cover that yours doesn't.

FAQs
Can I compare two websites' SEO for free?
Yes. Enter any two URLs and you get a side-by-side SEO comparison free, with no account needed. Add up to 5 URLs to compare several competitors in one run.
What does the website SEO comparison show?
An SEO score for each page plus a check-by-check breakdown of title tags, meta descriptions, H1s, HTTPS, robots.txt, XML sitemaps, Open Graph and canonical tags, so you can see exactly where each site wins or loses.
Can I compare my site's SEO against competitors?
That's the main use case. Enter your URL and up to 4 competitor URLs to benchmark against them and find the checks they pass that you don't.
Why does a competitor outrank me when my SEO score is higher?
Technical SEO is only part of ranking. If you outscore a competitor on these checks but still rank below them, the gap is usually content relevance or backlinks. Compare authority with the free Domain Rating checker next.
Does it compare whole websites or single pages?
Each URL you enter is audited as a page, together with its site's robots.txt and sitemap. Compare homepages for a site-level view, or compare the specific pages that compete for the same keyword.
