In the past I've heard that TripAdvisor has 60% market share for local reviews in the UK. Did Google Maps really climb that quickly? Are Instagram and TikTok not shaping tastes in London too? I feel like she might be assigning too much power to it just because that's what she used.
That's not to say I don't have gripes with how Google Maps works, but I just don't know why the other factors were not considered.
I don’t think I’ve met anyone in the UK who routinely checked tripadvisor for anything!
I just checked a few local restaurants to me in London that opened in the last few years, and the ratio of reviews is about 16:1 for google maps. It looks like stuff that’s been around longer has a much better ratio towards trip advisor though.
Almost certainly Instagram/tiktok are though. I know a few places which have been ruined by becoming TikTok tourist hotspots.
