Track real enquiries, not form fills.

Why are form fills the wrong goal?

A form fill only tells the platform someone submitted a form. It doesn’t say whether they were a real prospect, a competitor, a job seeker or a bot. Automated bidding then looks for more people like those who filled in forms, and the cheapest way to get more form fills is usually lower-quality traffic.

The result is familiar: cost per lead looks great in the dashboard, but the sales team says the leads are poor.

What should count as a conversion?

Something closer to revenue. Depending on your business, that might be:

• a qualified enquiry, checked by a person
• a booked appointment or discovery call
• a proposal sent
• a sale or signed client

The further down the funnel, the better the signal, but the fewer conversions you have. Platforms need a reasonable number of conversions to learn, so many businesses use qualified enquiries as the main goal and closed sales as a value signal.

How do you send real outcomes back to Google?

Google’s recommended approach is enhanced conversions for leads:

1. Your website’s Google tag captures hashed details, such as email address, when someone submits a form.
2. The lead goes into your CRM.
3. When the lead becomes qualified or turns into a sale, you upload that outcome with the same hashed details.
4. Google matches it to the ad interaction and learns which clicks produce real business.

It replaces the older offline conversion import that relied only on click IDs. Since June 2026, these uploads go through Google’s Data Manager rather than the older Google Ads API route, so check that your CRM connection has been updated.

And to Meta?

Meta’s Conversions API can receive lead stages from your CRM, such as qualified or converted, so Meta can optimise toward leads that progress rather than every submission. Lead forms inside Facebook and Instagram are especially prone to low-quality submissions, so feeding back outcomes matters even more there.

Where do you start?

1. Agree what a real enquiry is. Write a one-line definition the whole team uses.
2. Record it. Mark each lead in your CRM as qualified, not a fit, or spam. Even a spreadsheet works to begin with.
3. Capture the right details. Make sure forms collect a work email, and that your tag passes it to Google as an enhanced conversion.
4. Send outcomes back. Connect your CRM to Google and Meta, or upload outcomes on a regular schedule.
5. Change the goal. Once enough qualified conversions are flowing, make them the primary goal and demote raw form fills to secondary.

Does this work for small lead volumes?

Yes, with care. If you only get a handful of qualified leads a month, keep form fills as the bidding goal for now but monitor quality by campaign, and use qualified leads to decide where budget goes. As volumes grow, switch bidding to the better signal.
