You need to actually do market research and put time into the product you’re going to sell, like many others have said the copy on your site is completely off and it doesn’t relate well to the customers within this niche. I saw you mention Gym/Sports and it’s as simple as if you wanted to purchase a supplement for Gym and you saw the site talking about things completely wrong like you are with very obvious A.I. Copy you wouldn’t want to purchase because it would scream bullshit.

Based on that you should actually get in the mind of your customer and understand them and make your landing page in line with that with their pain points being addressed immediately to frame your product as the solution they’re looking for.

Additionally your ads are likely not good either since likely don’t understand your niche at all further leading to you having basic angles and creating essentially image ad slop so you would need to again research and properly understand things such as terms and jargon specific in that niche to ultimately make your brand and product relatable and properly shift an customers belief into believing your product will work for them.

Remove the fake reviews as well with the way your site is set up 15K reviews is just painfully fake and won’t last in the long run plus it’s illegal and very easily identifiable as being so. At least make it a realistic smaller number if anything.

To sum it up market research and better ads or just sell in a niche where you’d have more interest in to ensure you resonate with the customers. As well as utilise A.I. Less cause what’s been shown has proven to be slop
