Technical SEO is where most sites lose rankings

Content ranks. Backlinks help it rank. Technical foundations determine whether Google can crawl, index, understand, and prioritise your content in the first place. If technical is broken, content and links won’t fix it.

Most “SEO agencies” outsource technical to junior staff or ignore it entirely. We do it in-house because it’s the highest-leverage part of the whole discipline.

We audit and fix at the code level — theme changes, plugin removal, schema implementation, canonical audits, JS rendering. Not surface-level “SEO scores”.

What technical SEO covers

  • Crawlability. robots.txt, XML sitemaps, internal linking hierarchy, orphan page fixes.
  • Indexation. Canonical tags, noindex audits, hreflang for multi-region, duplicate content resolution.
  • Core Web Vitals. LCP, CLS, INP measurement and fixes.
  • Schema markup. Full JSON-LD @graph with connected entity structure. Organization, LocalBusiness, WebSite, Product, Article, FAQPage, BreadcrumbList.
  • JavaScript SEO. Rendering audits for React, Vue, Next.js sites. Pre-rendering strategies.
  • HTTPS + security headers. HSTS, HTTP → HTTPS enforcement, secure headers audit.
  • Log file analysis. What Googlebot actually crawls, how often, which URLs are being wasted.

Standalone audits vs ongoing retainer

Two ways to work with us on technical SEO:

  • Standalone technical audit. One-off deep-dive. 4-6 weeks. Full crawl analysis, prioritised fix list with implementation guidance, hand-off to your dev team (or we implement). Project quoted per scope.
  • Ongoing retainer. £400/month, rolling monthly. Continuous technical work alongside on-page and link building. Best for sites where technical needs ongoing maintenance.

FAQs

How much traffic can a technical audit unlock?

Varies — some sites see 10-30% uplift from technical fixes alone. Depends on how broken things are.

Do you fix things or just report?

Both. Standalone audits can be report-only or full implementation. Retainer includes implementation.

Do you handle JavaScript-heavy sites?

Yes — React, Next.js, Vue. We audit render behaviour and recommend fixes.

What tools do you use?

Screaming Frog, Ahrefs, Search Console, PageSpeed Insights, GSC, custom log analysis. Not just one dashboard.

Can you work with our dev team?

Yes — we hand off prioritised tickets with acceptance criteria your team can implement.

Do you handle migrations?

Yes — full technical migration with redirect mapping, canonical strategy, launch monitoring.
