It's not a lie, though.

It just means they saw some value in the product but didn't feel enough motivation to actually follow through and signup/use the product.

This is similar in many ways to someone answering "it's too expensive". The value prop is either not strong enough, not being marketed well enough, too complicated to start using... or the product is solving a pain point that people don't care enough about to build a business around it. Which is a serious question the OP needs to ask themselves. Unless their traffic<costs>conversion rate ratio is sufficient.

You can't expect customers to articulate that everytime (10-20% seems about right to me) because most people aren't actually thinking their actions through when visiting a landing page. Especially when it's via an ad... not something they searched out on Google or via referral.

Even if they did tell you they wouldn't necessarily know why... because you're assuming it was a rational thought process, or something they spent time thinking through, which is rarely the case. Books about how customers acting 'irrational' [1] are very useful at explaining this and are important to always be considering when doing marketing/UX design.
