SEO Compare
See exactly where you're winning and losing against a competitor: real performance, SEO, and on-page scores, side by side.
What does a side-by-side SEO comparison actually show?
This tool runs the same Lighthouse checks used in our Website Check tool against two URLs at once: your site and a competitor's, and lines the results up side by side. Beyond the four Lighthouse scores, it also compares a handful of concrete on-page signals (title tag length, whether a meta description exists, H1 heading count, word count) that a raw score alone does not surface. The goal is a fast, honest answer to "where exactly am I behind," not just "who scored higher."
Why compare on-page signals, not just Lighthouse scores?
Two sites can post nearly identical Lighthouse scores while differing sharply in what is actually on the page. A competitor with a longer, more thorough page and a properly filled meta description can out-rank a technically faster site with thin content. Comparing title length, meta description presence, H1 structure, and word count alongside the Lighthouse scores gives a fuller, more actionable picture of exactly where a competitor is beating you and where you already have the edge.
Google's own guide to how Search ranks resultsCommon questions
My competitor scored lower on Lighthouse but ranks above me. Why?
Lighthouse scores measure technical page quality (speed, accessibility, best practices), not ranking directly. Rankings also depend on factors this tool does not measure: backlinks, domain authority, content depth and relevance, and user engagement signals. A technically weaker page with far more authoritative backlinks or more comprehensive content can still outrank a technically cleaner one.
Should I try to match my competitor's word count exactly?
No. Word count is a rough proxy for depth of coverage, not a target to hit exactly. A page that thoroughly answers the searcher's question in 600 words is worth more than one padded to 2,000 words with repetition. Use a large word-count gap as a prompt to check whether your competitor is genuinely covering something you are missing, not as a number to copy.
How often should I re-run this comparison?
Whenever you make a meaningful change to either page, or every few months as a general check-in. Competitor pages change, algorithms shift, and a comparison that looked favorable six months ago can quietly go stale. This is a lightweight snapshot tool, not a monitoring service, so it is on you to re-run it periodically rather than expecting a one-time answer to hold forever.
