TECHNICAL SEO · LONDON

You can’t rank a site Google can’t read. Technical SEO is the foundation everything else sits on.

Content, links and authority matter, but none of it works if your technical foundations are broken. Slow pages, crawl errors, missing structured data, duplicate content and indexation problems silently kill rankings while you’re busy publishing blog posts. Mode audits, fixes and monitors the technical layer that makes everything else effective.

WHY TECHNICAL SEO GETS MISSED

Most SEO agencies focus on content and links. Technical issues sit quietly in the background, undermining everything.

01 Your page speed is poor. Core Web Vitals are failing. Google has been using page experience as a ranking signal since 2021 and your site hasn’t been optimised for it. Your content could be excellent and your rankings still suffer.
02 You have indexation problems you don’t know about. Pages being crawled that shouldn’t be, pages that should rank that aren’t indexed, duplicate content causing cannibalization. None of this is visible unless someone looks for it.
03 Your structured data is missing or broken. No schema markup means no rich results — no star ratings, no FAQ snippets, no site links. Your competitors with better technical setup are taking up more SERP real estate than you.
04 Your site was migrated and nobody checked the redirects. Old URLs returning 404s. Link equity from years of backlinks pointing to pages that no longer exist. Technical debt accumulating with every change.

COMMON TECHNICAL SEO ISSUES

The issues most sites have. The ones most agencies never look for.

Slow pages

A page that loads in 5 seconds has a 90% higher bounce rate than one that loads in 1 second. Speed is a ranking factor and a conversion factor simultaneously.

Duplicate content

Multiple URLs serving the same content confuse Google about which version to rank. Without canonical tags and proper redirect logic, you’re splitting your ranking signals.

Broken redirects

Every 404 error from a previously-linked page is lost link equity. Redirects from old URLs to new ones preserve the authority you’ve built. Broken redirects throw it away.

Missing schema

Rich results (star ratings, FAQ snippets, product data) are only available to sites with correctly implemented structured data. Without it, you take up one standard listing. With it, you can take up three times the space.
