How we can protect your ads from ad bots please suggest me better solution

I would recommend reviews, and honestly just make a really good product. An advertisement for a product is usually my red flag to avoid it I try to find products that speak based on their quality. If you do go for something like a YouTube review make sure it's with a YouTuber that has a clear stance on not letting reviewers control the message because that gives users significantly more confidence in that review. Which means that they are more likely to purchase that item

I don't know how practical it is for your particular product, but I'd strongly encourage using reviewers or sponsorships over traditional ads. Ads will get you a very non-tech savy crowd, but most people with even a bare modicum of tech knowledge are going to be running ad blockers. So not only are you paying for bots to click your ad, depending on your product you might not even be reaching those that would even be interested in your product in the first place.
