Technical SEO Audit Checklist for London Businesses in 2026

A technical SEO audit in London should not be a long spreadsheet that nobody uses. It should explain which issues stop people and search engines from reaching the right pages, then put the fixes in a sensible order.

Start with crawlability and indexation

Check whether Google can discover the pages that actually make money: service pages, ecommerce categories, important products, location pages and contact routes. Compare the XML sitemap with a fresh crawl and Google Search Console. If a commercial page is orphaned, blocked, duplicated or canonicalised to the wrong URL, it needs attention before content expansion begins.

Older WordPress sites often carry campaign pages, draft-style imports and redirect chains. Do not panic at every warning. Prioritise blocked revenue pages, mixed canonical signals, redirect loops and thin pages that compete with stronger URLs.

Measure speed like a customer

Core Web Vitals matter because they describe how the page feels on a real phone. Test the homepage, main service pages, popular articles and contact page. A fast homepage is not enough if the form or landing pages feel slow.

Look at image weight, render-blocking files, unused plugin assets, caching behaviour and layout shift. WP Rocket can help, but it cannot rescue a page that loads oversized media, duplicated scripts or heavy sliders on every route.

Check structure, schema and internal links

Every important page should have one clear H1, useful H2 sections, descriptive internal links and schema that matches the business. Service pages need to link to relevant case studies, articles and contact routes. Articles should link back to the services they support, such as SEO consulting or PPC management.

Turn the audit into a roadmap

A good audit ends with decisions. Fix crawl blockers first, improve pages with commercial intent next, then work through speed, schema, internal linking and content depth. That order keeps the project tied to enquiries and revenue rather than tool scores.

If you want a second pair of eyes, book a search strategy call and we can review the obvious blockers before a larger campaign starts.
