Glory
Say there's a little Tex-Mex joint down the street from your house. The place looks sad from the outside, but the cheese enchiladas are to die for, the white salsa for the chips is heaven in a bowl, and the margaritas are the best you've ever tasted. The staff is friendly and the prices are reasonable. You eat out at this restaurant at least once a week and, by golly, you think more people ought to give it a shot.
So, you go online and put up positive reviews on every foodie website and social media outlet you can think of. You take your friends out to eat at this restaurant, and soon they're regulars who're bringing family members, friends, and co-workers to eat there, too. Now, when you go to eat at the restaurant, it's always crowded, but the food is still amazing and the owner still greets you by name every time you walk in the door.
You've singlehandedly brought more business to a restaurant that deserves as many customers as it can get. You've started a movement. You are a shining example of the good restaurant critics can do. You get a cookie.
