This is a great question. Often, it's hard to tell if the product is wrong or if you're just failing to explain the value clearly on your landing page.
If you're worried about 'bad conversion' being the noise, I actually built a tool (AI Website Roast) that gives a brutal/honest look at exactly where a landing page is losing people. Might help you figure out if you need a pivot or just better positioning. Happy to run it on your URL if you want a second set of eyes? You can also put it in and try it.
