See Where a Competitor Wins on SEO

Side-by-side SEO scoring is the fastest way to identify the gap between your page and the one outranking you. Paste both URLs and the comparison highlights every check where the competitor edges you.

Pairs well with content optimization: fix the red gaps first, then revisit the green ones for marginal gains.

Why Use Our SEO Comparison Tool?

Animated Dual Score

Each URL gets its own animated SVG donut score and pass/warn/fail badge counts. The winner of the head-to-head is highlighted with a 🏆 tag and a glowing primary border so you instantly see which page leads, and by how many points.

Category Win Verdict

Beyond the overall score, every audit returns 8 category scores (meta tags, content, images, links, technical, crawlability, security, social). The Verdict panel counts category wins for each side separately so you can see strengths and weaknesses even when overall scores are close.

Per-Metric Diff Tables

A 12-row Page Overview table directly compares response time, page size, word count, link counts, image counts, schema, title/meta length, HTTPS, and sitemap, with the winner of each metric highlighted in its column color (blue for Site 1, purple for Site 2).

Priority Fixes, Both Sides

Both URLs get their own Priority Fixes column listing the top 6 highest-impact failures. So whether you are improving your own page or copying what makes a competitor win, you immediately know which 5-6 things to fix on each side.

Frequently Asked Questions

Common questions about SEO comparison.

How is this different from the SEO Checker?
The single-URL SEO Checker scores one page in isolation. The SEO Compare tool runs the same checks on two URLs and renders a head-to-head report, winner badges, side-by-side category bars, per-metric diff tables, and twin Priority Fixes columns. Use the Checker for individual audits, the Compare tool for benchmarking against a competitor or A/B comparing two of your own pages.
Why does my page lose the comparison even though it ranks higher?
On-page SEO is one input to ranking, but Google also weighs backlinks, domain authority, search intent match, freshness, brand signals, and Core Web Vitals (which this static-HTML tool does not measure). A higher SEO Compare score is necessary but not sufficient for ranking. Treat the result as a list of low-hanging fruit you can fix without waiting for Google to re-crawl.
Can I compare more than two URLs?
Not in a single run. The tool is purpose-built for two-way comparison so the visual layout (dual donut, side-by-side bars, twin tables) stays clear. To compare 3+ URLs, run the Compare tool multiple times, pair A vs B, then B vs C, or use the single-URL SEO Checker for each and tabulate the scores yourself.
Are both URLs fetched safely?
Both URLs are fetched server-side via wp_remote_get with a 20s timeout, redirect handling, and a clearly identified user-agent (PixellizeSEOCompare/1.0). Neither URL is logged, stored, or shared. The audit results render entirely in your browser from the AJAX response.
