Lead Quality Scoring: Assign Values to Your Leads

Why does counting every form fill hurt you?

In most lead generation accounts, the main conversion is a form submission. The bidding algorithm then works to produce as many form submissions as it can at your target cost.

It gets good at that. Within weeks you have more leads, a lower cost per lead, and a sales team frustrated that few of them close.

Lead quality scoring fixes the signal. You give each lead a value based on how likely it is to turn into revenue and send that value back to the ad platforms, so they optimize for outcomes instead of form fills.

Which lead stages should you define?

Before any technical work, agree with sales on the stages a lead passes through. A workable default:

1. Raw lead: form submitted.
2. Contactable: valid phone or email, and you reached them.
3. Qualified: fits your ideal customer profile and has a stated need.
4. Opportunity: meeting held, proposal in play.
5. Closed won: money received.

Write down the rule for each stage, so two salespeople would mark the same lead the same way.

How do you assign a value to each stage?

Work backwards from revenue, using your own CRM history. A worked example with made-up numbers:

• Average closed deal: €4,000
• 25% of opportunities close, so an opportunity is worth €1,000
• 40% of qualified leads become opportunities, so a qualified lead is worth €400
• 30% of contactable leads qualify, so a contactable lead is worth €120
• Raw lead: €0, or a token €1 so you can still see volume

Send the real deal value for closed-won.

The exact figures matter less than the ratios between stages. You’re telling the algorithm that one qualified lead is worth more than three contactable ones. Recalculate the values each quarter as your close rates change.

How do you send lead values to Google Ads and Meta?

The mechanics live in our offline conversion tracking setup guide. In short:

Google Ads: enhanced conversions for leads. Capture hashed customer data such as email on the form (and store the GCLID with the lead), then import each stage with its value when the lead moves in your CRM. Google recommends this over GCLID-only imports and handles imports through Data Manager (Google Ads Help).

Meta: Conversions API. Send the same stage events server-side with the value and the customer data or lead ID that ties them back to the original lead (Meta). For Instant Form leads, Meta’s Conversions API for CRM supports the Conversion Leads goal (Meta).

Whichever route you take, the CRM is the source of truth. If sales doesn’t update stages, the platforms learn from bad data.

How do you filter junk leads at the form?

Values improve the average lead. Filters raise the floor. Add:

• A honeypot field to catch bots without a visible captcha.
• Email validation that rejects disposable domains.
• One qualifying question, phrased as a routing question (“What’s your monthly budget?”) rather than a gate.
• Phone format validation for the countries you target.

Track raw and qualified lead volume before and after you add filters, so you can confirm you removed junk and kept good leads.

How long does it take to see results?

Offline values arrive with a delay. If leads take two weeks to reach qualified, the algorithm learns from two-week-old data, so changes show up slower than in e-commerce.

Give it a 60 to 90 day evaluation window. Upload stage changes daily, and leave targets alone for weeks at a time so the algorithm can adjust. Make sure your conversion window covers your sales cycle: Google Ads allows up to 90 days (Google Ads Help).

What does a working setup look like?

After a full cycle, expect cost per raw lead to rise, cost per qualified lead to fall, and pipeline value per euro spent to improve. If sales stops complaining about lead quality and you didn’t cut volume targets, the system works.

We build this for lead generation and B2B SaaS accounts, and run the bidding through our Google Ads management.

FAQ

What is lead quality scoring in Google Ads?

It’s assigning a value to each lead stage, such as qualified or opportunity, and importing those values as offline conversions so Smart Bidding favors clicks that turn into revenue.

How do I calculate the value of a qualified lead?

Multiply your average deal value by the share of qualified leads that close. With a €4,000 average deal and 10% of qualified leads closing, a qualified lead is worth €400.

Should I still count form submissions as conversions?

Keep them as a secondary conversion so you can see volume, and bid on a later stage with values. If your qualified volume is too low for bidding to learn from, keep bidding on form fills and import the stage values as secondary conversions until it grows.

How many conversions does bidding need to learn?

Google doesn’t publish one fixed number for every strategy. Pick the earliest stage that still separates good leads from bad, so you send enough events each month.
