Understanding SEO Scores
If you have ever run your website through an SEO tool, you have probably been given a score out of 100. But what does that number actually mean, and what should you be aiming for?
An SEO score is a composite measurement of how well your website follows search engine optimisation best practices. Different tools calculate it differently, but they generally assess the same core areas: on-page optimisation, technical health, content quality, and backlink strength.
The important thing to understand is that an SEO score is not a direct ranking factor. Google does not see your Semrush or Ahrefs score. What it does reflect is how well-positioned your site is to rank. A higher score means fewer technical barriers between your content and the people searching for it.
SEO Score Ranges: What They Mean
- 90 to 100: Excellent. Your site follows best practices comprehensively. You are in the top tier of UK small business websites. Maintenance and content creation should be your focus.
- 70 to 89: Good. You have a solid foundation with some areas for improvement. Most issues at this level are quick fixes that can yield noticeable results.
- 50 to 69: Average. This is where the majority of UK small businesses sit. There are likely several technical issues and missed opportunities holding you back.
- 30 to 49: Below average. Your website has significant SEO problems that are actively preventing you from ranking. Immediate action is needed.
- Below 30: Critical. Your site may have fundamental structural issues, penalties, or be nearly invisible to search engines.
Where Do Most UK Small Businesses Score?
Based on the audits we have conducted through OnOur, the average UK small business website scores between 45 and 65 on a standard SEO health check. That is not terrible, but it means there is significant room for improvement, and the businesses that close that gap tend to see meaningful increases in organic traffic within three to six months.
The encouraging news is that the most common issues are also the easiest to fix. You do not need to be an SEO expert to make real progress.
The 7 Most Common SEO Issues for UK Businesses
1. Missing or Duplicate Meta Titles and Descriptions
This is by far the most common issue we see. Many UK business websites either have no meta descriptions at all, or they use the same title tag across every page. Each page on your site needs a unique, descriptive title (under 60 characters) and meta description (under 155 characters) that includes relevant keywords.
Fix: Use a tool like Screaming Frog (free for up to 500 URLs) to crawl your site and identify pages with missing or duplicate meta tags. Then write unique tags for each page, starting with your highest-traffic pages.
2. No XML Sitemap
An XML sitemap tells search engines which pages on your site exist and when they were last updated. Without one, Google has to discover your pages by crawling links, which means some pages may never get indexed.
Fix: If you use WordPress, install Yoast SEO or Rank Math, both of which generate sitemaps automatically. For other platforms, use an online sitemap generator and submit it through Google Search Console.
3. Slow Mobile Page Speed
Google uses mobile-first indexing, which means it primarily uses the mobile version of your site for ranking. If your mobile site is slow, it directly impacts your search visibility. The benchmark to aim for is a Largest Contentful Paint (LCP) under 2.5 seconds.
Fix: Compress images (use WebP format where possible), enable browser caching, minimise JavaScript, and consider a content delivery network (CDN) if you serve customers across the UK.
4. Missing Alt Text on Images
Alt text serves two purposes: it makes your images accessible to screen readers, and it helps search engines understand what your images show. Missing alt text is a missed opportunity for both accessibility and SEO.
Fix: Go through your site and add descriptive alt text to every image. Be specific. Instead of "team photo," write "OnOur team meeting in the Manchester office." Avoid keyword stuffing.
5. No HTTPS
In 2026, there is no excuse for not having an SSL certificate. Google has used HTTPS as a ranking signal since 2014, and browsers now actively warn visitors about insecure sites. If your site still runs on HTTP, you are losing both rankings and trust.
Fix: Most hosting providers offer free SSL certificates through Let's Encrypt. Install it, then set up 301 redirects from HTTP to HTTPS for all pages.
6. Broken Internal Links
When you delete or move pages without setting up redirects, you create broken links. These frustrate visitors and waste the "link equity" that those pages had built up. Search engines also view lots of broken links as a sign of a poorly maintained site.
Fix: Use Screaming Frog or a free broken link checker to find 404 errors on your site. Set up 301 redirects for any important pages that have moved, and fix or remove links to pages that no longer exist.
7. Poor Heading Structure
Your page headings (H1, H2, H3) are not just for visual formatting. They tell search engines about the structure and hierarchy of your content. Common issues include multiple H1 tags on a single page, skipping heading levels (going from H1 straight to H4), or not using headings at all.
Fix: Each page should have exactly one H1 tag (usually the page title). Use H2 tags for main sections and H3 tags for subsections within those. Think of it like a table of contents.
How to Track Your Progress
Once you have made improvements, here is how to measure the impact:
- Re-run your SEO audit using the same tool you used initially. Compare your score to see the numerical improvement.
- Monitor Google Search Console for changes in impressions, clicks, and average position over the following weeks.
- Check your Core Web Vitals in Search Console to see if your speed improvements are registering.
- Track keyword rankings for your target terms using a tool like Ubersuggest or SE Ranking.
SEO improvements are not instant. Allow three to six months to see the full impact of technical fixes. Content and backlink improvements can take even longer. The key is consistency.
