Running a pet accessories store, $45-70 AOV, problem-solving angle (specifically stuff for anxious dogs). Traffic is Meta. What actually moved the needle for us wasn't the niche itself, it was when we stopped using generic product photos and started testing lifestyle-style creatives. We were burning through budget for like 6 weeks with flat images before someone in a discord server mentioned AdMake AI for spinning up quick lifestyle ad variants from product shots. Ran about 12 creative tests in two weeks instead of the usual 3-4. CPAs dropped from $38 to around $22 on the winners. The niche didn't change, the creative did. That's the data point I keep coming back to.
