How to Check the SEO Health of Your Website
Checking the SEO health of your website helps you find issues that may make it harder for search engines to crawl, understand and rank your pages. It can also reveal problems that affect visitors, such as slow loading times, broken links or content that is difficult to use on a mobile device.
A website SEO check is not a one-off task. Regular reviews help you spot changes, prioritise fixes and keep your site accessible to both search engines and people.
What does website SEO health mean?
SEO health is the overall condition of the factors that influence a website’s visibility in organic search results. These include technical performance, page content, site structure, user experience and links from other websites.
A strong SEO health score does not guarantee high rankings. Search engines consider many signals, and results can vary by query and competition. An audit is best used to identify clear problems and opportunities rather than as a promise of specific results.
Check whether search engines can find your pages
Start by confirming that important pages can be crawled and indexed. A page that cannot be accessed or indexed is unlikely to appear in search results.
- Review your robots.txt file to make sure it is not blocking pages you want search engines to access.
- Check that important pages do not have an unintended
noindexdirective. - Submit an up-to-date XML sitemap through Google Search Console and other relevant webmaster tools.
- Look for crawl errors, such as pages returning a 404 or server errors.
- Check that preferred page versions use consistent canonical tags.
Use Google Search Console’s indexing reports and URL Inspection tool to investigate specific pages. If a page is not indexed, check whether that is intentional before making changes.
Review your site’s technical foundations
Technical problems can affect how search engines access your website and how visitors experience it. Review the following areas:
- HTTPS: Make sure your website uses a secure HTTPS connection and that old HTTP URLs redirect appropriately.
- Redirects: Check for broken redirects, redirect loops and unnecessary chains.
- Mobile usability: Test key pages on mobile devices. Text should be readable, and buttons and links should be easy to use.
- Page speed: Identify pages that load slowly, then investigate large images, unnecessary scripts and other possible causes.
- Core Web Vitals: Use tools such as PageSpeed Insights and Search Console to review loading, responsiveness and visual stability.
- Structured data: Check that any structured data is accurate and follows search engine guidelines. Valid markup does not guarantee enhanced search results.
Tools such as Screaming Frog SEO Spider, Sitebulb and other site crawlers can help you find technical issues across many URLs. Automated reports are useful starting points, but review findings before acting on them.
Check your pages’ on-page SEO
Each important page should clearly communicate what it is about and match the needs of its intended audience. Review your main pages for:
- Page titles: Make sure each title is descriptive, distinctive and relevant to the page.
- Meta descriptions: Write a concise summary that accurately reflects the page and encourages relevant searchers to visit.
- Headings: Use a clear heading structure to organise the content. Headings should help readers understand the page, not just include keywords.
- URLs: Keep URLs clear and descriptive where possible, and avoid changing established URLs without a good reason.
- Images: Use suitable image formats and file sizes. Add useful alt text when an image conveys information; decorative images can usually have empty alt text.
- Internal links: Link related pages together using clear, helpful link text.
Avoid forcing keywords into titles or paragraphs. Search-friendly content should sound natural, answer the reader’s question and provide information that is useful and accurate.
Assess content quality and relevance
Content is central to a useful SEO strategy. Review whether your pages offer clear, reliable information and whether they meet the purpose behind the search query.
- Identify pages with outdated, inaccurate or incomplete information.
- Look for pages that cover the same topic and may compete with each other.
- Improve content that receives impressions but attracts few clicks, where the page could better match the searcher’s needs.
- Consider combining or redirecting genuinely overlapping pages, taking care to preserve useful content and relevant links.
- Make it clear who created or reviewed important content, particularly where accuracy and trust are essential.
Do not remove pages simply because they have low traffic. First consider their purpose, audience, links and value to the wider site.
Review internal links and website structure
A clear site structure helps visitors find information and helps search engines understand how pages relate to one another. Important pages should be reachable through relevant navigation or contextual links, rather than being isolated.
Check for broken internal links, pages with no links pointing to them, and overly complicated navigation. Use descriptive anchor text so people know what to expect when they follow a link.
Check your website’s backlinks
Backlinks are links from other websites to yours. Relevant, editorially earned links can help people discover your content and may contribute to search visibility. Review your backlink profile using Google Search Console or reputable SEO tools.
Focus on whether links come from relevant, trustworthy sources. Avoid buying links or using schemes designed to manipulate rankings. If you spot suspicious links, investigate them carefully rather than assuming every unfamiliar link is harmful.
Measure performance and set priorities
Use Google Search Console to review impressions, clicks, queries and indexing information. Analytics tools can help you understand what visitors do after arriving on your site. Compare data over time and consider seasonality, changes to your website and shifts in search demand.
When you find issues, prioritise them by impact and effort. For example, fixing a widespread indexing problem is often more urgent than adjusting a minor detail on a low-value page. Keep a record of changes so you can assess whether they improve performance.
A practical SEO health checklist
- Important pages can be crawled and indexed.
- Your XML sitemap is current and submitted.
- Key pages work correctly on mobile and use HTTPS.
- There are no widespread broken links or server errors.
- Page titles, headings and descriptions are clear and relevant.
- Content is accurate, useful and aligned with audience needs.
- Important pages are connected through sensible internal links.
- Performance issues have been identified and prioritised.
- Search performance is monitored regularly.
How often should you check SEO health?
For most websites, a light review each month and a more detailed audit every few months is a sensible starting point. Check sooner after a redesign, migration, major content update or sudden change in search performance. Large or frequently updated websites may need more regular monitoring.
Keep your website healthy over time
To check the SEO health of your website effectively, combine technical checks with a careful review of content, structure and performance data. Fix the issues that matter most to visitors and search visibility, then monitor the results. Consistent, thoughtful improvements are more valuable than chasing a perfect audit score.
