01The challenge

The cobbler’s children had no shoes.

Harrowgate sold performance hosting but its own site failed Core Web Vitals and its plan pages cannibalised each other.

Every plan page promised sub-second WordPress. Prospects who ran the homepage through a speed test saw a red INP score, and Google saw eleven near-identical plan pages fighting over the same four searches. Rankings for the money terms swung weekly between URLs, so none of them held a top-five position long enough to earn sign-ups.

  1. CRIT

    01 Performance
    Mobile INP 410ms at p75

    A chat widget and a 380KB analytics bundle blocked the main thread on every tap. The plan toggle triggered a full re-render of three pricing tables.

  2. CRIT

    02 Architecture
    11 plan pages competing for 4 intents

    “WordPress hosting”, “managed WordPress hosting UK” and “fast WordPress hosting” each had 3–4 URLs trading positions week to week.

  3. WARN

    03 Performance
    LCP 3.4s from an unoptimised hero video

    A 2.1MB autoplay loop was the LCP element on every plan page; the poster image had no fetch priority.

  4. WARN

    04 Structured data
    Conflicting Product markup

    Two plugins each emitted Product schema with different prices, so neither was eligible for price snippets.

  5. WARN

    05 Crawl
    3,200 faceted parameter URLs indexed

    Data-centre and billing-period filters generated crawlable URLs with near-identical content.

  6. INFO

    06 Internal links
    “Click here” anchors to plan pages

    68% of internal links to commercial pages used generic anchors; the blog linked more to the old plans than the new ones.

  7. INFO

    07 Content
    No comparison content at all

    Searches like “Harrowgate vs Kinsta” were answered by affiliate sites with outdated pricing.

03The strategy

Four cables, one patch panel.

Built on our Signal plan (technical seo). Each tactic plugs into a single measurable signal, so we could see exactly which change moved which number.

  1. PORT A1

    Core Web Vitals

    We measured field data per template, not lab scores per page. Every fix was tied to a p75 metric and guarded by a performance budget in CI so a new plugin cannot silently undo it.

  2. PORT A2

    Comparison pages

    Six head-to-head pages with dated, reproducible benchmarks and a published test rig. They answer “vs” searches that affiliates used to own, and they link to exactly one plan.

  3. PORT A3

    Structured data

    One schema graph: Organization, BreadcrumbList and a Product with Offer per plan. Duplicate plugin output removed so prices are consistent and eligible for rich results.

  4. PORT A4

    Internal linking

    An intent ledger maps every keyword cluster to a single canonical URL. Anchors were rewritten to describe the destination, and blog posts now pass authority to plans, not to each other.
