SEO Comparison Tool: compare your page against a competitor's
Comparisons puts your page and a competitor's page side by side, audited with the exact same engine, so you can see precisely where they out-rank you on-page. You get a symmetric scorecard of 18 SEO metrics, a keyword gap list and an AI-written plan to close it. Free with a RankNibbler account.
Compare two web pages, measured the same way
Comparisons audits a competitor's page URL with the identical engine that powers your own site audit, then lays both pages out in one side-by-side scorecard. Because both columns are scored by the same checks, the result is a like-for-like read on which page is stronger on-page, not two reports stitched together. You start it from any scanned page's Tools tab: paste the competitor's equivalent URL, and the tool fetches and audits their page on the spot. For a fair read, compare like with like — your product page against their product page, your guide against their guide.
18 on-page metrics, side by side with a clear winner
The scorecard compares 18 metrics across SEO, accessibility, security, content, structure and speed: SEO score, Accessibility score, Security grade, Word count, Title length, Meta description length, H1 count, H2 count, Internal links, Images missing alt, Schema count, Speakable schema, FAQ Q&A pairs, Direct-answer opening, Question-format H2s, Text-to-HTML ratio, Page size and Response time. Each row highlights the winner using the right rule for that metric — higher is better for word count and internal links, lower is better for page size and response time, and target ranges for title length, meta description and H1 count — so you can see at a glance exactly where you lead and where you trail.
- Higher is better — e.g. word count, internal links, schema count.
- Lower is better — images missing alt, page size, response time.
- Target range — title 50–60 chars, meta 120–160 chars, H1 = 1.
- Grade rank — security uses its letter grade to pick the winner.
Find the keyword and schema gaps you're missing
Beyond the numbers, Comparisons pulls out the keywords and phrases the competitor emphasises on the page that yours doesn't use — up to 18 — giving you a ready-made list of topics to work in. It also flags any schema types their page carries that yours is missing. Together these show you the concrete on-page differences behind a ranking gap — the wording, the structured data and the coverage — rather than leaving you to eyeball two pages yourself.
An AI plan to close the gap
Once both pages are scored, Comparisons generates a prioritised action plan built from the full audit of each page. It calls out where the competitor beats you, lists keyword gaps with exactly where on your page to add each one, and gives prioritised fixes with paste-ready examples — a suggested title, an H2, an FAQ question and answer or a schema snippet — plus a few quick wins. It turns the side-by-side read into specific steps you can apply the same day.
Save comparisons and revisit them anytime
Every comparison is saved to the page it was run from, so reopening a scanned page brings back the full scorecard, keyword gaps and plan instantly without re-auditing the competitor. A Refresh button re-runs the audit when you want a fresh read. The central Comparisons page collects every saved comparison for your account, grouped by competitor site, so you can see all your page-vs-page match-ups and when each was last run in one place.
Comparisons vs Competitors: which to use
Comparisons is page-vs-page on-page analysis: it audits two specific URLs and shows which page is better optimised. The separate Competitors feature works at the keyword level, tracking how rival sites rank for your project's keywords across the search results we capture. Use Comparisons when you have a competitor page out-ranking yours and want to know why on-page; use Competitors when you want to see who you're up against for a keyword set. They complement each other — find your rivals with Competitors, then beat a specific page with Comparisons.
How to compare two web pages for SEO
Three steps:

2. Add the competitor URL
Under Competitor analysis, paste the competitor's equivalent page URL and run the comparison.
3. Read the scorecard and plan
Review the 18-metric side-by-side, the keyword and schema gaps, and the AI plan, then apply the fixes and save it for later.
Frequently asked questions
What does an SEO comparison tool do?
It puts two web pages side by side and shows how each performs on-page, so you can see which is better optimised. RankNibbler's Comparisons audits your page and a competitor's page with the same engine, then compares 18 metrics including SEO score, word count, title and meta length, headings, internal links, schema, speed and more, highlighting the winner of each.
How do I compare two web pages for SEO?
In RankNibbler, scan your page, open its Tools tab and choose Competitor analysis, then paste the competitor's equivalent page URL. The tool audits their page on the spot and shows a side-by-side scorecard of 18 on-page metrics, the keyword and schema gaps between the two pages, and an AI plan to close them.
Which metrics does the comparison show?
Exactly 18: SEO score, Accessibility score, Security grade, Word count, Title length, Meta description length, H1 count, H2 count, Internal links, Images missing alt, Schema count, Speakable schema, FAQ Q&A pairs, Direct-answer opening, Question-format H2s, Text-to-HTML ratio, Page size and Response time. Each row marks which page wins.
How does it decide which page wins a metric?
It uses the right rule for each metric. Higher is better for things like word count and internal links; lower is better for page size, response time and images missing alt; target ranges apply to title length (50-60 characters), meta description (120-160) and H1 count (one); and security uses a letter-grade rank. The stronger value in each row is highlighted.
Is the RankNibbler comparison tool free?
Yes. Comparisons, like every tool in RankNibbler, is free with a RankNibbler account. You can run page-vs-page comparisons, save them and revisit them at no cost.
Should I compare my homepage to a competitor's homepage?
Compare like with like. For a fair, useful read, match pages that play the same role - your product page against their product page, your guide against their guide - rather than comparing a homepage to a category or pricing page. The scorecard is most actionable when both pages target the same intent.
Can I save a comparison and look at it again later?
Yes. Each comparison is saved to the page it was run from, so reopening that page brings back the full scorecard and plan instantly without re-auditing. A Refresh button re-runs it when you want fresh numbers, and the central Comparisons page lists every saved comparison for your account, grouped by competitor.
How is Comparisons different from the Competitors feature?
Comparisons is page-URL vs page-URL on-page analysis - it audits two specific pages and shows which is better optimised. Competitors works at the keyword level, tracking how rival sites rank for your project's keywords. Use Comparisons to beat a specific page; use Competitors to see who ranks for your keywords.
Beat the page that's beating you
