FAQ
What does an on-page SEO audit include?
An on-page SEO audit covers title tags, meta descriptions, H1 and heading structure, keyword placement, content quality, internal linking and image alt text. Each element is checked page by page and issues are ranked by their likely impact on search rankings.
How is an on-page audit different from a technical SEO audit?
An on-page SEO audit focuses on the content and HTML elements within individual pages, such as titles, headings and copy. A technical SEO audit looks at how search engines crawl and index the site, covering issues like site speed, crawl errors, redirects and structured data. Most full SEO audits cover both.
How much does an on-page SEO audit cost in the UK?
A professional on-page SEO audit in the UK typically costs between £500 and £2,500, depending on the size of the site and the depth of analysis required. Smaller sites with fewer than 50 pages can often be audited at the lower end of that range, while larger ecommerce sites with complex page structures sit at the higher end.
How often should I run an on-page SEO audit?
Running an on-page SEO audit every six to twelve months is a reasonable baseline for most sites. Ecommerce sites that add products regularly or publish new content frequently should audit more often, as new pages can introduce duplicate titles, missing meta descriptions and thin content faster than manual reviews can catch them.
Key Answer
An on-page SEO audit is a structured review of the HTML elements and content on individual website pages, checking whether they are correctly configured to rank in search results. It covers title tags, meta descriptions, heading structure, keyword usage, internal links and content quality. A complete audit produces a prioritised issue list for each page, showing which fixes will have the greatest impact on rankings.
