    Overview

    What is Technical SEO?

    Technical SEO covers everything that affects how search engines crawl, index, and render your website. It includes site speed, mobile performance, URL structure, XML sitemaps, robots.txt, structured data, and Core Web Vitals.

    Most businesses ignore technical SEO until something breaks. A slow site, poor mobile experience, or crawl errors can silently kill your rankings and revenue potential.

    We audit your site's technical foundation and fix what's holding you back—often unlocking significant ranking improvements without changing a single word of content.

    Technical SEO directly impacts revenue: faster sites convert better, crawlable sites rank higher, and structured data drives richer search results.

    A 1-second improvement in page speed can increase conversions by up to 7%.

    Visionary is a world-leading SEO agency trusted by brands across the UK and beyond. Our senior specialists combine deep technical expertise with commercial strategy to deliver measurable organic growth.

    "Chris is a real master of SEO and PPC. I'll never forget the time he discovered what could have been catastrophic SEO issue, prior to a new big website launch that would have cost the business £100,000s (that every other so-called SEO expert we'd engaged had missed)."

    Case Study — TECHNICAL SEO · B2B SAAS

    Novidea: Top of Search for "Insurance Software" UK + US in 3 Months

    Novidea had serious indexability issues keeping its insurtech SaaS platform out of Google's index. We led the site migration to fix the technical foundation — crawl architecture, canonicalisation, render path, hreflang for dual-market — then layered topical content depth and link signal alignment around the primary commercial keyword.
