Getting Leads But Most Are Not Good

The quality of leads should first be analyzed via keywords or search terms, and then against location, device, and landing page intent. If the clicks are relevant, yet the leads are poor, then there is an issue with the form/offering.

You can try checking your keywords and targeting first and also check the search terms to see where the low quality leads are coming from and then you can adjust the targeting and focus more on the traffic that brings the real customers.
