Signs Your Website Needs Technical SEO Work

Technical problems rarely announce themselves. These are the patterns we see most often before a client gets in touch.

  • Pages missing from Google, or marked “Crawled, currently not indexed” in Search Console.
  • Rankings that slip after a redesign or a move to a new platform.
  • Slow mobile pages that fail Core Web Vitals in field data.
  • Duplicate URLs from filters, tracking parameters or www and non-www versions.
  • Redirect chains and broken links left behind by past changes.
  • Rich results that disappeared because structured data broke.
  • JavaScript-heavy pages where key text only appears after scripts run.
  • Wrong pages ranking for important searches because canonicals point the wrong way.

Crawlability and Indexation Optimisation

Search engines have to discover a page, render it and decide it deserves a place in the index before it can rank. Problems at any of those stages waste the effort that went into your content.

Crawl paths and internal links

We map how Googlebot moves through your site, remove dead ends and orphaned pages, and make sure important pages sit within a few clicks of the homepage.

XML sitemaps, robots.txt and canonical tags

Sitemaps should list only the pages you want indexed. Robots rules should block waste without hiding content. Canonical tags should point to one clear version of each page. We audit all three and fix the conflicts between them.

Website indexation issues

Using the Page Indexing report and URL Inspection tool in Google Search Console, we diagnose why pages are excluded and resolve the cause rather than resubmitting them and hoping.

Core Web Vitals Optimisation and Website Speed

Core Web Vitals measure how fast a page loads, how quickly it responds and how stable it stays while loading. Google assesses them at the 75th percentile of real visits, so a fast test on your office broadband is not the same as a pass.

MetricWhat it measuresGoodPoorTypical fixes
Largest Contentful Paint (LCP)How long the main content takes to appear2.5s or lessOver 4sImage sizing, WebP or AVIF, server response, preloading the hero image

Platforms

Technical SEO for WordPress, Shopify and Ecommerce

WordPress

Theme and plugin bloat, caching, image handling, Yoast or Rank Math settings, and archive pages that should not be indexed.

Shopify

Duplicate collection paths, app scripts slowing pages, theme Liquid fixes and product structured data.

Ecommerce stores

Faceted navigation, out-of-stock and discontinued products, pagination and crawl budget on large catalogues.

JavaScript SEO

React, Vue and Next.js sites checked for rendering, hydration and content that crawlers cannot see.

Structured data

Schema Markup Services and Structured Data Implementation

Structured data describes your business, products, articles and services in a format search engines read directly. Done well, it supports rich results and helps Google connect your pages to the right entities.

We write JSON-LD for Organization, LocalBusiness, Service, Product, Article, Breadcrumb and FAQ types, test it in Google’s Rich Results Test and make sure every value matches the visible page, which Google requires.

Website migration SEO

Redesigns, domain changes and platform moves are where technical SEO matters most. We build redirect maps from your old URLs, test staging before launch and monitor rankings and crawl errors for weeks afterwards.

  • Launch day: redirect testing, sitemap submission and live crawl.

Technical SEO FAQs

Questions About Technical SEO

What does a technical SEO specialist do?

A technical SEO specialist makes sure search engines can crawl, render and index your website efficiently. That covers site architecture, sitemaps, robots rules, canonical tags, redirects, page speed, Core Web Vitals, structured data and JavaScript rendering.

The aim is to remove anything that stops good content from ranking, then keep the site healthy as it changes.

Do Core Web Vitals affect rankings?

They are part of Google’s page experience signals. Strong scores will not lift weak content above better answers, but slow, unstable pages can lose out where competing results are otherwise similar. Faster pages also convert better, which matters whether or not rankings move.

Can you work with our developers?

Yes. Many clients have in-house or agency developers. We write clear tickets with the problem, the fix, the affected URLs and how to test it, then review the change before release. Where you have no developer, we can make WordPress and Shopify fixes directly.

How do you protect rankings during a website migration?

We record every indexed URL and its rankings, map each one to its new address with a 301 redirect, crawl the staging site before launch and monitor Search Console closely after go-live. Most traffic losses after migrations come from missing redirects or blocked staging settings left in place, and both are easy to prevent with a checklist.

How long do technical SEO fixes take to show results?

Indexing and crawl fixes can show within days to a few weeks, once Google recrawls the affected pages. Core Web Vitals data in Search Console uses a rolling 28-day window of real visits, so speed improvements take about a month to appear in reports.
