Recently dived in to the nutrition market and its very competitive. My ads did not work at all for months. One of my items, which I have on google shop, is matcha tea. The ctr was .5 for a while but I wanted to make it better since the benchmark is 1.0. So I changed the description on the feed to add some more keywords then uploaded it again. Since then the ctr is at 0.00 and Im on day 3 now like this. Any clues on why this is going on. Anything I can do other than up bids to like 2 dollars. Thanks in advance.
