The basics

What technical SEO is

Technical SEO covers everything about a site that affects search apart from the words and the links. Can Google reach every page? Does it understand which version of a page is the main one? Do pages load quickly on a phone? Is the structured data correct?

Faults here quietly cap everything else. A strong page that Google cannot index will never rank, and a slow template can drag down every page that uses it.

Many sites carry faults for years without anyone noticing, because the site looks fine to people. Typical culprits are plugins that create duplicate pages, redirects that chain into loops and old staging copies left open to crawlers.

We find these with crawlers, Search Console data and server logs where available, then fix them or hand clear instructions to your developer. Local firms get technical checks as part of every Sheffield SEO package.

The audit

Technical SEO audit: what we check

Every technical SEO audit we run covers these areas, ranked by impact.

CrawlingBlocked pages, orphan pages, broken links and redirect chains.
IndexingCanonicals, noindex tags, duplicates, thin pages and index bloat.
Core Web VitalsLoading, layout shift and responsiveness on mobile.
Structured dataSchema for your business, services, products, reviews and FAQs.
Internal linksHow link value and context flow between your pages.
JavaScriptWhether content built by scripts is actually seen by Google.
InternationalHreflang and regional versions where a site serves several countries.
Security and hostingHTTPS, mixed content, server errors and response times.
Server racks with green status lights and network cables
Redirect maps are built and tested before launch day
Migrations

Site migrations without the crash

Moving to a new website, platform or domain is the most common cause of sudden ranking losses we see. Old URLs vanish, redirects are missed and content that ranked is cut because nobody knew it mattered.

We plan migrations before the new site goes live: a full map of old to new URLs, redirects tested on staging, content and metadata carried across, and tracking checked on launch day. After launch we watch crawl errors and rankings daily until things settle.

Fixing vs reporting

We fix, not just report

A long PDF of problems helps nobody unless something changes.

What we usually find first

The four faults we find most often on business websites.

Duplicate pages

The same page reachable at several addresses, splitting signals.

Slow images

Large uncompressed photos that add seconds on a phone.

Broken internal links

Links to pages that moved or were deleted.

Missing structured data

No schema for the business, services or reviews.

Monitoring

Ongoing technical monitoring

  • Weekly crawlNew errors caught early
  • Search ConsoleIndex and coverage alerts
  • Speed checksTemplates and images
  • Release checksAfter every site update

Technical health is not a one-off job. Plugins update, developers push changes and content teams add pages. Each can break something.

On every monthly package we crawl your site, watch Search Console for new problems and check speed on your main templates. When your developer releases an update, we check the important pages the same day.

For firms that want a one-off review without monthly support, our SEO consultant in Sheffield service covers a full audit and the top fixes for a fixed fee.

  • Crawl every month
  • Alerts watched
  • Speed tracked
  • Changes checked
Platforms

Platforms we work on

Most of our technical work is on WordPress, Shopify, Squarespace, Wix, Webflow and custom builds. Each has its own habits: WordPress plugins that duplicate pages, Shopify collection URLs that multiply, page builders that slow everything down.

Knowing those habits means we find the usual faults quickly and spend the time on the problems unique to your site.

We also work with headless and JavaScript-heavy sites, where the question is often whether Google sees the content at all. Rendering tests show what Google receives, not just what a browser shows.

If a platform genuinely limits what search can achieve, we say so and explain the options, rather than patching around it for months.

Speed

Core Web Vitals in practice

The changes that most often move speed scores on business sites.

Image sizesServing images at the size they display, in modern formats.
Fewer scriptsRemoving or delaying chat widgets, trackers and sliders that block loading.
Stable layoutsReserving space for images and banners so pages do not jump.
Caching and hostingMaking sure pages are cached and served quickly.

What is a technical SEO audit?

A review of how search engines crawl, render and index your site, with every issue ranked by how much it matters.

How long does an audit take?

The free audit takes one working day. A full Kickstart audit with fixes usually takes two weeks.

Do you need access to our server?

Not usually. Access to the site, Search Console and analytics is enough for most audits.

Can you work with our developers?

Yes. Many clients keep their developers and use us for diagnosis and priorities.

Do Core Web Vitals really affect rankings?

They are one signal among many. Slow pages also lose visitors, which matters more.

Can you help with a migration already done?

Yes. We can often recover much of the lost traffic by fixing redirects and restoring content.

Do you work on Shopify, WordPress and custom sites?

Yes, and on most other common platforms.

What is technical SEO in simple terms?

Making sure search engines can find, read and trust every page you want them to show.
