Imagine you're a restaurant owner, the goal is to analyze the reviewers other activity, such as whether they've reviewed your competitors, their average spending range, and their favorite types of dishes and more, all based on their reviews in other places in general. This would give you a more complete picture of who they are.
Do you think this kind of insight would be useful?
Do you even consider people who leave Google Maps reviews to be actual customers? And would having detailed information about them help you make more informed business decisions?
Would love to hear your take on this
He had a problem with someone and half his friends and family left bad reviews that were fake. The worst part is he didn't want to sell something to that person because the product had a problem but that person thought he didn't want to sell to him and got mad.
Go and ask restaurant owners. They are your potential customers.
Or better yet, ask them what their problems are and work on those.
The best likely outcome is you gain experience trying to talk to potential customers. Some experience acting instead of imagining. Good luck.
