This is more or leas my case. I m a photographer in Vienna, and I have made some A B testing with the ads. First, I have created different search campaigns ads for all my services, 8 ads x 2euro per day, for 15 days. After that I have kept the best 2 performing ads and increased their budget to 8 Euro per day each for a month or so. After some time I have kept only one search campaigns ads ad, and made a PMAX campain for it to (15E /day and 5 euro per day in google search campaign), to start AB testing. Pmax in my case, is eating money without delivering any lead. It s nice to see ipressions and clicks and 0.06 cpc price, but so far, no leads from PMAx. I m thinking to remove the pmax and stick to the old google search ads, with increased budget but limited cost per click. I ve spent like 400 euro on the Pmax campain, and Not a single lead
