City rankings for Technical SEO

The full explanation behind every place (the claims, their sources and what each agency is missing) lives on the city pages.

How a place here is earned

  • For an intent page, at least one claim on file supports the intent under the page's rubric, and at least one of those claims comes from a source outside Vendar. Our own service listings and profile tags describe the intent but document nothing, so they add weight to a vendor that already has outside evidence and never earn a rank on their own. Vendors without outside evidence appear below the ranking, unranked, never padded into it.
  • For an intent page, at least one of those claims documents work the vendor has done: a case study, a project or portfolio entry, or a client review. Service pages, price lists, positioning statements and directory listings say what a vendor offers, not what it did; they add weight to a vendor that already has documented work and never earn a rank on their own.
  • Rank order is the score, highest first. Ties break on evidence points, then on the number of third-party claims, then alphabetically.

The weights and the gate are published in full.

Questions this page answers

What counts as Technical SEO evidence?
A claim counts as technical-SEO evidence when a source on file names engineering-side search work: crawl budget and indexation fixes, Core Web Vitals or page-speed results, site architecture and internal linking, canonicalisation, structured data, JavaScript rendering, log-file analysis, or a platform migration that preserved rankings. Client reviews describing an audit that shipped fixes carry the most weight. A Vendar service listing or profile tag is our own label and never earns a rank on its own.
How is this hub different from the city pages?
This page merges the city rankings for Technical SEO into one national list and keeps each agency's best city result. The city pages rank the same evidence for one market at a time, with the full explanation behind every place.
Do agencies pay to appear here?
Paid visibility never changes the order of a listing.
