Pulse Analysis

Rebranding a well‑known online service is a massive undertaking, yet the most visible sign of success is often the name that appears in Google’s search results. In a recent exchange on Bluesky, John Mueller of Google was asked why a UK‑based appointment platform that switched from ‘Wahanda’ to ‘Treatwell’ in 2015 still displayed the old brand in its SERP title tags. Despite a complete on‑page overhaul, 301 redirects, and a clean URL structure, the legacy name persisted, prompting the SEO community to wonder what hidden signals keep Google from updating its index.

The persistence can be traced to several subtle factors. Google’s crawler still encounters the former brand in footer referral codes and in a sitemap that references 404 pages bearing the old name. Even a single outdated link can act as a legacy signal, reinforcing the historic brand in the index. Mueller’s recommendation—to use the domain name as an alternate site name—leverages Google’s site‑name algorithm, which gives higher weight to the domain when title‑tag data is ambiguous. Removing all residual references and submitting a refreshed sitemap are essential steps to break the loop.

For marketers, the episode underscores that rebranding is not solely a design exercise; it demands rigorous technical hygiene. Brands must audit every corner of their web property—footers, structured data, sitemaps, and even third‑party backlinks—to ensure consistency. Monitoring SERP titles after a name change provides early warning of indexing lag, allowing teams to file a reconsideration request or use Google’s troubleshooting guide. Ultimately, a clean, domain‑centric site name helps preserve brand equity, improves click‑through rates, and signals to Google that the new identity is definitive.
