So, a fair bit recently I have been looking for various things, and I like to use reviews to gauge how a firm is to deal with or a restaurant is to eat at.
For travel and restaurants, TripAdvisor is my favourite, but google reviews is one less step.
I have recently discovered a bit jump in the average rating of many places I've looked at and reading the reviews, I often will see a lot of 1 Review Reviewers giving 5 star reviews.
Recently we wanted a heat pump, magically my facebook feed started getting some "good deals" offered by companies I'd not heard of before. Investigating google says they have 4.9 stars of 170 reviews. When looking they are almost all (but not entirely) 5 star reviews by people with foreign-sounding names (Which isn't a problem on it's own). No mention of this company at ALL on nocowboys for example.
Same thing with a local pizza place that opened recently. 4.7 stars average, 90 reviews, most looking pretty suspicious.
Not sure what point I wanted to make, just sharing in case anyone else has anything to add I guess.
