Technical SEO agency
Technical SEO that helps Google find, crawl and index the right pages.®
Crawl and index
We find the pages Google can't reach, the ones it shouldn't index, and the Search Console errors holding the rest back.
Structure and signals
Clear architecture, consistent canonicals, clean redirects and valid structured data, so search engines know which pages matter.
Fixes, not just a report.®
Our technical SEO services start with a prioritised list of what stops pages being crawled, indexed or understood. On platforms we manage, we make the fixes. On other sites, we brief your developer.

The detail
What to expect from a technical SEO agency
When you need a technical SEO audit
A good technical SEO agency starts with the symptoms: good pages missing from Google, traffic that fell after a redesign, or a platform or domain change coming up. A technical SEO audit also suits sites that have grown for years without anyone checking how the pieces fit together. We also run one before a migration, so you know what the current site does well before anything moves.
If your content is thin or targets the wrong searches, technical fixes won't solve that alone. Our guide to technical SEO versus content SEO explains which to fix first.
Crawlability, indexing and canonicals
Google can only follow standard HTML links with an href, so we check menus, filters and buttons built with JavaScript. We then compare our crawl with Search Console to see which pages Google has indexed, skipped or treated as duplicates.
Redirects and canonical tags are strong signals for which version of a page Google shows, and sitemaps are a weak one. Google weighs them rather than treating them as rules, so we make all three agree.
Sitemaps, robots.txt and structured data
Google ignores the priority and changefreq values in XML sitemaps but uses lastmod when the dates are accurate, so we keep sitemaps to live, canonical URLs with honest dates. Robots.txt manages crawling; keeping a page out of search is a job for noindex.
For structured data we use JSON-LD, the format Google recommends, and validate it in the Rich Results Test. Valid markup makes a page eligible for rich results but never guarantees them.
Site architecture, JavaScript and migrations
Google says every page you care about should be linked from at least one other page on your site. We plan a hierarchy where services, locations and guides link to each other with descriptive anchor text. On the Mould Matters site, 16 services, 130+ area pages and 26 guides were planned to work as one system. Anchor text should make sense out of context, which helps visitors as much as crawlers.
Google renders JavaScript in a separate step after crawling, so we check that important content and links appear in the rendered page. For migrations we follow Google's site move guidance: map every old URL, use permanent server-side redirects and generally keep them for at least a year.
How it fits with speed, redesigns and content
Page speed overlaps with technical SEO but needs its own tools, so Core Web Vitals work sits under website speed optimisation. If you're replacing your site, our website redesign service builds the redirect plan in from the start.
Once the foundations are sound, SEO and growth marketing adds content and links on top of them.
What a technical SEO agency should report
We send regular reports on a schedule we agree with you, covering what changed: pages indexed, Search Console errors cleared, redirects working and structured data valid, alongside organic traffic and enquiries. Rankings can take time to respond, so we show the leading signals as well as the outcome.
Sites keep changing, so we recommend a recheck after every redesign or large content update.
What to have ready
Bring Search Console and analytics access, admin access to your CMS or a developer contact, and any planned changes to the site. A list of the pages that matter most to the business helps us prioritise.
01 — Discover
We crawl the site, review Search Console's indexing and sitemap reports, and check how key pages render.
02 — Define
We rank every issue by impact and effort. On platforms we manage we make the fixes; on other sites your developer gets a prioritised fix list.
03 — Deliver
We fix redirects, canonicals, sitemaps, robots.txt, structured data and internal links, testing each change.
04 — Develop
We monitor indexing and errors in Search Console, recheck after site releases and report what changed.

Pricing & FAQ
Technical SEO audit pricing.®
The audit is a fixed project fee, quoted after a call. Fixes and monitoring are quoted as a fixed project or monthly fee. Most audits take 1 to 3 weeks.
What does a technical SEO agency actually do?
It makes sure search engines can crawl, render and index the pages you want found, and understand them. That covers site structure, internal links, canonicals, redirects, XML sitemaps, robots.txt and structured data.
How much does a technical SEO audit cost?
It depends on the size and complexity of your site. The audit is a fixed fee quoted after a call; fixes are quoted separately or briefed to your developer.
How long does a technical SEO audit take?
Most audits take one to three weeks, depending on the number of pages and how much investigation is needed.
What's included in the audit?
A full crawl, Search Console indexing and sitemap reports, canonicals, redirects, broken links, robots.txt, internal linking, JavaScript rendering and structured data, delivered as a prioritised list of fixes.
Do you fix the issues or just report them?
Both. On platforms we manage, such as Framer, Shopify or WordPress builds we run, we make the fixes ourselves. On other sites we brief your developer with a prioritised fix list.
Can you protect our rankings during a redesign or migration?
Yes. Google advises mapping every old URL to its new one and using permanent server-side redirects, generally kept for at least a year. We build that map and test the redirects at launch.
Does robots.txt keep a page out of Google?
No. Robots.txt manages crawling, and a blocked URL can still appear in results. Use a noindex rule instead, and leave the page crawlable so Google can see it.
Is page speed part of technical SEO?
It overlaps. Google says Core Web Vitals are used by its ranking systems, but relevance comes first. Deeper speed work sits with our website speed optimisation service.
