Google Business Profile, in detail
The Google Business Profile is the primary asset that determines map pack ranking. It is a free Google product. Most studios have one. Most studios treat it as a "set and forget" listing, which is why most studios do not rank.
The non-negotiables for a London fitness business profile: complete every field, no exceptions. Pick the most specific primary category (Yoga Studio, Pilates Studio, CrossFit Box, Boxing Gym, Reformer Pilates Studio, Personal Trainer, not generic "Gym"). Add every relevant secondary category. Set hours accurately. Add holiday hours and bank holiday closures. Upload at least 50 photos covering the studio exterior, interior, equipment, classes in progress, the team, and any treatment or recovery rooms.
Then keep it active. Post weekly: a class spotlight, a member story, a new programme launch, an instructor profile, a recent transformation. Respond to every review within 48 hours. Upload a few new photos every month. Update the timetable link if class times change.
The single biggest unforced error London fitness studios make is letting the Business Profile go stale. A profile that gets weekly posts will outrank a profile with the same review count but no recent activity. Recency is a strong ranking signal.
