What Is Technical SEO?

The process of optimising a website's infrastructure so search engines can crawl, render, and index it efficiently — covering speed, structure, schema, redirects, and mobile-friendliness.

Example

Reload Mode's technical SEO audit identifies 12 crawl errors, 3 redirect chains, and missing schema markup — fixing these improves indexing by 40%.

Fixing technical SEO issues alone (crawl errors, broken links, slow pages, duplicate content) increases organic traffic by an average of 19% within 3 months — without any new content creation — according to SEMrush's State of Content Marketing report.

What it applies to

Every website, but especially sites with large page counts, complex URL structures, international targeting, or significant legacy content that may have accumulated technical debt over time.

Technical SEO audit process

  • Crawl the site: Use Screaming Frog (free up to 500 URLs) to crawl all pages and export data on status codes, title tags, meta descriptions, H1s, word count, response time, and links.
  • Check indexation: In Google Search Console → Indexing → Pages — review all "Not indexed" pages. Understand why each is excluded and whether that is intentional.
  • Fix 4xx errors: 404 errors on pages with internal links or backlinks waste crawl budget and lose link equity. Redirect them to the most relevant live page.
  • Resolve redirect chains: Any A→B→C chain should become A→C. Use Screaming Frog's redirect chain report.
  • Fix duplicate content: Ensure canonical tags are set correctly. Every page should either be the canonical URL or point to one.
  • Improve Core Web Vitals: Fix LCP, CLS, and INP issues identified in Google Search Console.
  • Add schema markup: Implement FAQPage, BreadcrumbList, and Organization schema for the appropriate page types.

In Webflow

Webflow's clean HTML output and automatic sitemap generation provide a strong technical SEO baseline. Focus technical SEO effort on: custom canonical tag configuration for CMS paginated pages, structured data implementation via custom code, Core Web Vitals optimisation (primarily image and JavaScript), and redirect management via the Hosting settings.
