How to Compare Two Websites’ SEO (Free Tool, No Signup)

Why compare two websites’ SEO at all?

SEO is a relative game. Google doesn’t rank pages against a fixed standard — it ranks them against each other. So running an audit of your own site tells you how you’re doing in isolation, which is useful, but only half the picture. The more valuable question is: how does my site compare to the competitor I’m trying to outrank?

When you can see both sites side-by-side on the same ten signals, the strategy writes itself. If they’re beating you on word count and schema markup, you know the shape of the gap. If you’re ahead on internal linking and page speed, you know where you’re already winning. No guessing, no expensive subscriptions, no hour-long audit reports.

The ten SEO signals that actually matter in a side-by-side comparison

There are hundreds of SEO signals Google considers, but for a practical head-to-head check you only need the ten that are (a) extractable from the raw HTML, and (b) genuinely meaningful to rankings. Our SEO Competitor Comparison tool measures all ten automatically in about fifteen seconds. Here’s what they are and why each one matters.

1. Title length. Ideal range is 50–60 characters. Shorter and you’re wasting prime ranking real estate; longer and Google truncates it in the SERP. This is the single highest-leverage on-page signal.

2. Meta description length. 120–160 characters is the sweet spot. Meta descriptions don’t directly affect rankings, but they heavily affect click-through rate — and click-through rate feeds back into how Google evaluates your relevance.

3. H1 heading. One clear H1 that tells Google what the page is about. Multiple H1s confuse; zero H1s is an own goal. You’d be surprised how many big sites have zero.

4. Word count. Thin pages under 300 words rarely rank. Longer isn’t automatically better — but if your competitor has 3,000 words covering a topic and you have 900, you now know why they’re ranking above you.

5. Schema types present. Structured data helps Google understand what your page is about beyond just reading the copy. A page with LocalBusiness, FAQPage, and BreadcrumbList schema is giving Google far more information than a page with none.

6. Image alt coverage. The percentage of images with descriptive alt text. Partly an accessibility issue, partly an SEO issue — alt text helps Google understand image content and contributes to topical relevance.

7. Internal links. How much a page is connected to the rest of the site. High internal linking tells Google a page is important within the site’s architecture; low internal linking suggests the page is orphaned or undervalued.

8. HTML size. Page size affects load speed, and load speed affects rankings. Bloated pages with huge HTML payloads often indicate messy code or excessive tracking scripts — both of which Google penalises.

9. Canonical tag. A self-referencing canonical URL tells Google “this is the definitive version of this page”. Missing canonicals cause duplicate-content headaches; wrong canonicals can make pages disappear from search entirely.

10. Mobile viewport. A viewport meta tag is the baseline for mobile optimisation. Any site missing it in 2026 has probably got bigger problems, but the check still catches surprises on legacy builds.

A real example: our site vs the UK’s #1 “affordable SEO” result

Let’s run this for real. As of writing, we rank #5 for “affordable SEO” in the UK — above us at #1 sits theaffordableseocompany.co.uk. Interesting match-up, because we also rank #1 for the longer-tail “affordable SEO for small business” and get cited by name in Google’s AI Overview for that query. Something’s clearly different between how the two sites are built.

Here’s what the comparison tool shows when we pitch getyourwebsiteseen.co.uk against theaffordableseocompany.co.uk:

• Word count: 1,942 vs 119. A sixteen-to-one gap on their flagship keyword.
• H1 heading: 1 vs 0. The site ranking above us for “affordable SEO” has no H1 tag at all.
• Schema types: 3 (LocalBusiness, WebSite, FAQPage) vs 1 (WebSite only).
• Internal links: 117 vs 27. Four times the internal linking depth.
• Title length: 64 chars vs 88. Theirs will truncate in the SERP; ours won’t.
• Description length: 154 chars vs 187. Same story.

Final score: we win 6 of 10. Two ties. Their only win is HTML size, where their lighter page beats ours by a few kilobytes.

So how are they ranking above us? Most likely a combination of domain age, backlink profile, and anchor text on incoming links. None of which change how the page is built — which is why the comparison still matters. Their ranking position is borrowed from external factors; the page itself is a weaker SEO artefact than ours. That’s a beatable position, not a moat.

How to interpret your own comparison results

The pattern we saw above is extremely common. A site ranks through history, authority, or links, but the page itself is underbuilt. When you run the tool on your own competitors, look for these three things:

Where you’re already winning. Most small business owners assume their competitors are miles ahead. Usually they’re not. If you win 4 or 5 rows out of 10, you’re already in the fight — the issue is visibility, not quality.

Where the quick wins are. If a competitor has more schema types than you, that’s typically a 30-minute job for a developer. If they have more internal links to their key pages, that’s an afternoon of editing in WordPress. These are cheap moves with compounding returns.

Where the real gaps are. Word count and content depth are the honest ones. If they’re answering ten questions on a topic and you’re answering three, the fix isn’t quick — but at least now you know what the fix looks like. Everything else is fiddling at the edges.

Try it on your own site vs a competitor

The SEO Competitor Comparison tool is free, no signup, and gives you a full side-by-side scorecard in about fifteen seconds. Enter your URL on the left, any competitor’s URL on the right, and the tool does the rest.

Run it against your top three competitors, not just one. Patterns emerge quickly — if all three are ahead of you on schema types, that’s your first priority. If only one is, it’s less urgent. Three comparisons takes under a minute and gives you a properly informed picture of where you actually stand.

Want a prioritised plan for closing the gap after you’ve run yours? Send us the URL you compared and we’ll send back specific next steps, free, no sales call. Or use the comparison tool and the “Would I Buy From This Site?” checklist together — the first tells you where you stand on SEO, the second tells you whether visitors will actually buy once they arrive. Both answers matter.
