An SEO audit checks whether search engines and people can find and use your site. In 2026 search results are more competitive, AI-generated answers are changing how people discover brands, and users expect pages that get to the point. A slow, unclear or outdated site can lose enquiries without anyone noticing.
A good audit helps you find what is working, what is holding you back and what needs to be fixed first. It also stops you wasting £100s or £1000s on content, paid media or redesign work before the foundations are right.
If you want a deeper review, working with an SEO audit agency can help you turn a long list of issues into a clear action plan.
Technical SEO checks
1. Check crawlability and indexation
Start by checking whether Google can find and index your important pages. Review your robots.txt file, XML sitemap, canonical tags and noindex rules. A page cannot bring in leads if it is blocked, buried or missing from the index.
Use Google Search Console to compare submitted pages with indexed pages. If key service pages are excluded, find out why before moving on to content or links.
2. Review site speed and Core Web Vitals
Slow pages frustrate users and make every marketing channel work harder. Test your key landing pages on mobile and desktop. Look at Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift.
If images are too large, scripts are heavy or your site takes too long to respond, these issues should be prioritised. A technical SEO agency can help you separate quick fixes from deeper development work.
3. Test the mobile experience
Most users will judge your website on a phone before they ever see it on a desktop. Check menus, forms, buttons, enquiry journeys and payment steps on real mobile devices.
Make sure users can read the text, tap calls to action and complete forms without zooming, pinching or getting blocked by pop-ups. A mobile issue that feels small internally can cost you real enquiries.
4. Clean up duplicate and low-value URLs
Old campaign pages, thin blog posts, test URLs and duplicate pages can all weaken your site. Review which pages deserve to stay, which should be improved and which should be removed or redirected.
This is especially important for larger sites, ecommerce websites and businesses that have been through several redesigns.
5. Check tracking and conversion data
An audit is only useful if your data is reliable. Check GA4, Google Tag Manager, form submissions, phone clicks and key events. Make sure you are tracking the actions that matter commercially, as well as page views.
For cleaner reporting, review your setup with a data and analytics agency or check whether your Google Tag Manager account has become messy over time.
Content and on-page SEO checks
6. Map keywords to the right pages
Each important keyword should have a clear destination page. If 3 pages are fighting for the same term, Google may struggle to decide which one to rank.
Create a simple keyword-to-URL map. Match every priority phrase to user intent, whether the searcher wants information, comparison, pricing or a service provider.
7. Review content quality and usefulness
Your content should answer the question properly. Repeating the keyword is not enough. Check whether each page is helpful, current and specific to your audience.
Add real examples, practical advice and clear next steps. If you work in the UK, include UK context, regulations, costs and examples where relevant. This makes the content more useful and more trustworthy.
8. Improve title tags, headings and meta descriptions
Review your title tags, meta descriptions, H1s and H2s. They should be clear, relevant and written for humans.
A title should explain what the page offers. A meta description should give someone a reason to click. Headings should make the page easier to scan, with keywords only where they fit.
For service pages, SEO / organic marketing should always connect search intent with a clear conversion journey.
9. Strengthen internal linking
Internal links help users move through your site and help search engines understand which pages are important. Link from relevant blogs to service pages, from service pages to case studies and from broader guides to more detailed pages.
Avoid generic anchors like ‘click here’. Use natural phrases that explain what the linked page is about. For example, a page about rebuilds could link to SEO web design where the context fits.
10. Refresh outdated content
Old content is not always bad, but outdated content can quietly damage performance. Look for articles with falling clicks, old dates, weak examples or outdated advice.
Refresh them with current information, clearer formatting and better internal links. In many cases, improving an existing page is more cost-effective than writing something new from scratch.
Link and authority checks
11. Review backlink quality
Backlinks still matter, but quality matters more than volume. Audit who links to you, which pages attract links and whether any links look spammy or irrelevant.
Do not panic over every low-quality link. Focus on patterns. If your competitors have strong editorial links and you mainly have weak directories, that shows an authority gap.
12. Check anchor text balance
Your anchor text should look natural. If too many links use the same exact-match keyword, it can appear forced. Mix branded anchors, topical anchors and natural phrases.
The same applies internally. You do not need every link to use a commercial keyword. The link should make sense in the sentence.
13. Audit local SEO signals
If you serve a local or regional market, check your name, address and phone number across your website, Google Business Profile and key listings. Inconsistent details can confuse users and search engines.
Also review location pages. Each one needs content specific to that place. A copied page with only the town name changed does not count.
14. Connect SEO with paid search and conversion data
SEO should not sit in a silo. Review which paid search terms convert, which landing pages perform well and where users drop off.
This can help you prioritise pages that are more likely to generate revenue. A paid advertising agency London can often uncover search terms and messaging insights that make your SEO strategy sharper.
15. Build a clear SEO roadmap
The final step is turning your audit into a plan. Do not treat every issue equally. Prioritise fixes based on impact, effort and commercial value.
Start with technical blockers, then move to high-value content gaps, internal links and authority building. If your website is a major lead source, connect the work to real outcomes such as enquiries, pipeline and revenue in £.
For long-term growth, an SEO performance agency can help you look past rankings to the pages and journeys that bring in enquiries.
Where to start
By the end of an audit you should know what is broken and which fix comes first.
If the findings run to hundreds of rows, sort them by the pages that bring in enquiries and work down from there.
