Technical SEO cost depends on the size and condition of your site and whether you need a one-off audit, a fix-it project or ongoing monthly work. Be wary of anyone who quotes a price before looking at your site, or who guarantees rankings.
What decides the cost of technical SEO
The three ways to buy it
- A one-off audit: a review of crawling, indexing, speed, schema and content structure, with a prioritised list of fixes. Good if you have developers or a team who can make the changes.
- A fix-it project: the audit plus the work to implement the fixes, such as redirects, schema, templates and speed improvements. Good for a site that has clear problems or is being rebuilt.
- Ongoing monthly work: regular technical checks, content structure, schema and reporting. Good once the foundation is fixed and you want steady gains. One of our case studies shows what a small number of hours a month can do for a local business.
What pushes the price up or down
- Site size: a 20-page site and a 20,000-page site are very different jobs.
- Platform: a site on Webflow or a well-built CMS is usually simpler than a heavily customised legacy one.
- Current condition: a clean site needs light touch work, whereas a site with indexing, redirect or speed problems needs more.
- Migrations: moving platforms needs careful redirect mapping and checks. See migrating to Webflow without losing rankings.
- Access and speed of approvals: work moves faster when changes can be made directly.
What to ask for
- A clear scope: exactly what will be checked and fixed.
- A prioritised list of fixes ranked by likely impact.
- Reporting in clicks from Google Search Console, so you can see the effect.
- Who actually does the work.
Red flags
- Guaranteed rankings or guaranteed positions. Nobody controls Google.
- A fixed price quoted without looking at your site.
- Vague deliverables like "SEO optimisation" with no list of what will be done.
- No access to your Search Console data or reports.
How to get a real number
The reliable way is to start with an audit. It tells you what is wrong, what is worth fixing first and what the work will involve, and you can then decide whether to do it yourself, hand it to your developer or have it done for you. Request a technical audit and we will tell you what we find. For realistic timeframes once the work starts, read how long SEO takes.
Is technical SEO a one-off cost or ongoing?
Usually both. The foundation fixes are often a one-off project, then ongoing work keeps the site healthy and builds on it as search and AI results change.
Can I just do technical SEO myself?
Some of it, yes. Basic checks in Google Search Console and fixing titles and headings are accessible. Redirects, schema, indexing and speed problems usually need technical experience.
Will technical SEO guarantee more traffic?
No. It removes the barriers that stop good pages being found, but rankings depend on competition, content and trust, and nobody can guarantee a result.
