Free SEO Health Score Checker | Instant Website Analysis

What Does the SEO Health Score Check?

Our SEO health checker runs 15+ checks across your page and gives you an instant score out of 100:

Deep checks (optional): Enable these to crawl for broken internal links and identify heavy images that should be converted to WebP/AVIF format. Takes a bit longer but finds issues basic scans miss.

Understanding Your SEO Health Score

Your score gives you a quick indication of where your website stands. Here’s how to interpret it:

Common Issues the SEO Health Checker Finds

After checking thousands of small business websites, these are the problems we see most often:

• Title tags too long or too short — Google displays 50-60 characters. Longer titles get cut off with “…” which looks unprofessional and loses keywords.
• Missing or weak meta descriptions — No description means Google writes one for you (usually badly). Our tool shows character count so you can optimise.
• Missing or duplicate H1 tags — Every page needs exactly one H1. Multiple H1s or no H1 confuses search engines about your page topic.
• Thin content — Pages under 300 words rarely rank. The tool shows word count and reading time so you know if you need to expand.
• Heavy images not in WebP/AVIF — Large JPEGs and PNGs slow your site. Our deep check lists every image that needs converting, with file sizes.
• Broken internal links — 404 errors waste link equity and frustrate users. The deep check crawls your site and lists every broken link.
• Missing canonical tags — Without canonicals, Google might index the wrong version of your page or see duplicate content.
• No Schema/JSON-LD — Structured data helps Google understand your content and can earn rich snippets in search results.
• Missing Open Graph tags — No og:title or og:description means your pages look rubbish when shared on social media.

The tool gives you “Quick fixes” at the bottom — prioritised recommendations based on what will have the biggest impact.

What This Tool Doesn’t Check

Our SEO health checker is a quick on-page diagnostic — great for spotting issues fast, but not a replacement for a full audit. For the complete picture, you’d also need:

• Backlink profile analysis — Who’s linking to you and the quality of those links
• Keyword rankings — Where you actually rank for target search terms
• Competitor comparison — How your pages stack up against those ranking above you
• Core Web Vitals — Detailed page speed metrics (LCP, FID, CLS)
• Site-wide crawl — Indexing problems, orphan pages, crawl budget issues
• Local SEO signals — Google Business Profile, citations, NAP consistency
• Content cannibalisation — Whether your pages compete against each other for the same keywords
• Search intent alignment — Whether your content matches what searchers actually want

Want the full picture? Our free comprehensive SEO audit covers all of this — two detailed reports reviewed by a human, not just automated tools.

How to Use Your SEO Health Score

Getting a score is just the first step. Here’s how to turn insights into action:

1. Fix critical issues first
Missing title tags, broken HTTPS, or no H1 headings? These are the problems that have the biggest impact. Start here.

2. Check your most important pages
Run the checker on your homepage, main service pages, and any pages you want to rank. Each page might have different issues.

3. Compare before and after
Made some fixes? Run the checker again to see your improved score. Track your progress over time.

4. Prioritise by impact
Not all issues are equal. A missing title tag matters more than a slightly long meta description. Focus on what moves the needle.

5. Don’t chase a perfect score
An 85 with great content will outrank a 100 with thin content. The score is a guide, not the goal. Real rankings come from solving user problems.

FAQ: SEO Health Score Checker

Is this SEO health checker really free?
Yes — completely free, no signup required, no limits on how many pages you check. We built it to help UK small businesses understand their SEO without paying for expensive tools.

What’s the difference between basic and deep checks?
Basic checks analyse your page’s HTML instantly — title, meta, H1, word count, etc. Deep checks actually crawl your site to find broken internal links and identify heavy images that need converting to WebP/AVIF. Deep checks take longer but find issues that basic scans miss.

Why does the tool show my images need converting?
Large JPEG and PNG images slow your site down. WebP and AVIF formats are much smaller with the same quality. The tool lists every heavy image with its file size so you know exactly what to fix.

What do the coloured badges mean?
Green = good, no action needed. Orange/yellow = could be improved. Red = problem that needs fixing. The overall score weighs all these factors together.

Will improving my score guarantee better rankings?
Fixing on-page issues removes barriers to ranking. But SEO involves many factors including content quality, backlinks, and competition. A better score gives you a solid foundation — actual rankings depend on the full picture.

Can I check competitor websites?
Yes — enter any public URL. Comparing your pages to competitors can reveal why they might be outranking you.

What should I do if my score is low?
Look at the “Quick fixes” section at the bottom of your results — these are prioritised recommendations. Start with red issues (critical), then orange (important). If you need help, our free comprehensive SEO audit provides detailed recommendations reviewed by a human.
