Separate a bad contact from an unfinished sale
Spam, a duplicate, a request for a different service and a customer who is still thinking it over are different categories. If they all get the status "not sold," the report doesn't explain why. Introduce short values a sales rep can choose based on the conversation, not on a guess.
Review a sample of inquiries from two or three sources. For each, note whether it fits the service, whether the person could be reached, the stage and the reason it stalled. Use data without names or phone numbers in shared reports. The goal is to find a pattern, not to pass around customers' contact details.

Compare the promise with what the business offers
An ad might grab attention with the word "free," while only the initial consultation is actually free. People leave their details with a different expectation, and the sales rep spends time correcting it. A cheap lead in that situation is not a win.
Walk the path as a visitor would (see the landing page check): the creative, the page headline, the terms, the button, the form. Every step should be about the same offer. Key limitations need to be explained before someone gets in touch, not for the first time on a call.
Check what happens after submission
Does the team know a lead has come in? Is someone assigned to it? Can they see the selected service and the message? Losing this data forces the conversation to start from scratch and can look careless to the customer.
Look separately at how long it takes to give the first meaningful reply. An automatic "we've received your request" is not a consultation. Every working schedule needs a clear routine: who replies during business hours, what happens in the evening and how missed contacts are tracked.

Fix the cause you actually found
If irrelevant queries dominate, review your audience targeting, search terms and the offer copy. If the right people don't get a reply, start with your sales process. If conversations reach the proposal stage and then stall, look at your terms and the objections you hear.
Look at the whole path from the ad to the deal, not at a form counter: that's how lead generation works. Loss reasons and next steps are easy to track in a CRM for handling inquiries, and if the problem is the queries themselves, Google Ads management with regular cleanup will help.
