Callum Whitfield

Technical SEO Lead

Callum handles the part of SEO that happens before anyone writes anything: crawl architecture, indexation diagnostics, rendering, and site performance. His most-cited finding is the client whose JavaScript-rendered site was leaving 60% of pages effectively uncrawled. Moving to server rendering took indexation from 38% to 96% in six weeks, before a single new page was published.

He designs our programmatic SEO systems and enforces the data-sufficiency threshold that decides whether a templated page has enough unique data to justify existing: the technical companion to Ines's editorial content-value gate, not the same rule twice.

He came from a front-end engineering background, which is why our technical recommendations tend to arrive as pull requests, not PDFs.

Programmatic SEO without the penalty

One client's previous contractor generated 3,000 template pages. Google indexed 4% and traffic fell. We shipped 1,412 and hit 97%. The difference was a quality gate.

The site migration that doesn't lose traffic

Most migrations lose organic traffic for reasons decided weeks before launch. The checklist that matters, and the three failures that account for nearly all of it.

Structured data that actually earns rich results

Most sites emit schema nobody validated. It fails silently, with no error and no warning, and the markup is simply ignored. Here's what breaks and how to catch it.

Your locations shouldn't all use the same GBP category

The standard multi-location advice is one consistent Google Business Profile category across every branch. Now that AI Overviews query a location against its category, that consistency is actively excluding the branches whose real business doesn't match it.
