A founder opens Google Ads on a Monday and sees forty new trial sign-ups from last week. Good week. Three days later, the sales team has emailed all forty. Six replied. Two booked a demo. One of the forty was a student writing a paper on project management tools, three used addresses that bounced, and a handful never logged in after the welcome screen.
Google Ads saw forty wins. It will spend this week's budget looking for forty more people exactly like them, including the student.
That gap, between what the ad account counts and what sales can close, is this chapter. It builds the measurement we put under every software account: each entry point tagged, the sign-up followed across web addresses, the CRM reporting its verdict to Google Ads, and a single funnel stage steering the bids. The examples come from twelve project management, CRM, payroll and scheduling companies we found running Search ads in the US. Your product and your numbers will differ. The setup is the same.
A Free Sign-Up Costs the Buyer Nothing and Tells Google Ads Almost Nothing
Of the eleven free trials on those twelve sites, ten say no credit card is needed. Most of the sign-up forms ask for four fields or fewer, and seven of the eleven let a visitor skip the form entirely with a Google account. That is good product design: a curious buyer is inside the app before the curiosity wears off.
It also means a sign-up proves almost nothing. Nobody hesitates over a free account that asks for an email address. Competitors sign up to look around, students for coursework, job seekers to prepare for interviews, and bots because the form lets them.
None of that would matter if the sign-up were only a number in a report. It isn't. Whatever you mark as a conversion becomes the definition of success Google's bidding chases. Feed it sign-ups and it gets very good at finding people who sign up. In one Reddit thread, a software founder who had been bidding on sign-ups found that roughly 30% of them were low-quality or fake, and worried, reasonably, that the bidding had been trained on the junk. One account, not a benchmark, but the mechanism applies to all of them.
Keep counting sign-ups. Stop letting them steer.
Software Buyers Come In Through Trials, Demo Calendars, Sales Forms and the Phone. Google Counts Only the Ones You Tag.
Before anything gets filtered, every way in needs its own counter. Across the twelve sites, the doors looked like this:
- The trial or free plan. Eleven of twelve offer one. Count the completed sign-up, meaning the moment the account exists, not the click on the "Start free trial" button.
- The demo calendar. Of the eleven sites that offer a demo, ten let the buyer pick a meeting time right away instead of waiting for a callback. Five of those ten use Calendly, and Calendly gives you two ways to count a booking. The simplest is its built-in Google Analytics 4 connection: mark the booking as a key event and import it into Google Ads. If the calendar sits on your page through Calendly's own embed code, it also announces each booking to the page, so Tag Manager can fire the conversion directly. A plain Calendly link still works if bookers land on a thank-you page you tag. With any other demo tool, check for the same paths before you assume a booking counts.
- The contact-sales form. Fire the conversion on the confirmation screen, after the form actually submits.
- Chat. Seven of the twelve run one. Count it only when it collects contact details.
- The phone. Only a few of the sites print a phone number, and they are the HR and payroll companies. If you take calls, Google's own call tracking counts calls from ads and from a forwarding number on your site. A call becomes a conversion once it lasts longer than a threshold you set, and Google's help pages leave the number to you. We set 30 seconds, because a buyer leaving a voicemail is still a buyer. CallRail and CallTrackingMetrics add recordings and CRM connections, if your sales team lives on the phone.
- Email clicks, content downloads and webinar sign-ups. Track them, but as secondary signals. A PDF download is interest, not intent.
Six of 11 Software Sign-Ups We Checked Finish on a Different Web Address. Google Ads Loses the Trail Unless the Tag Follows.
The ad sends a visitor to www.yourproduct.com. They click the trial button and finish signing up on app.yourproduct.com, or account., or signup., or auth. Six of the eleven self-serve sign-ups we checked finish on a different address from the marketing site. The login link points to a separate address on eleven of twelve.
To a tag, a new address can look like a new visitor: the click stays behind on the first site, and the sign-up on the second arrives as an orphan. Google Analytics solves it with cross-domain measurement, which keeps one visitor recognized as the same person while they move between your addresses. List every address the sign-up touches, and the click travels with the visitor.
Two more installation rules keep the counts honest:
- One tag manager, not three. Google wants its Google tag doing the conversion tracking, and on a site that loads both the bare tag and Tag Manager it tells you to pick one method, leaning toward Tag Manager. Eight of the twelve sites show a Tag Manager container in their page code.
- Check before you trust. Tag Assistant shows what fires on each page. Run it through a full test sign-up, across both addresses, before any campaign spends a dollar.
Primary Conversions Steer the Bids. Secondary Conversions Only Report.
Google splits conversion actions into two kinds. Primary actions appear in the Conversions column and are used for bidding. Secondary actions appear in the All Conversions column and are only reported.
For a new software account the sorting usually goes like this:
- Primary: the qualified lead or held demo, once your CRM sends it back (the next two sections). Until it does, the booked demo or the completed sign-up has to stand in.
- Secondary: raw sign-ups once qualified leads are flowing, contact-sales forms that duplicate the demo, chats, calls, downloads, webinar sign-ups.
Three settings sit inside each conversion action:
- Count. For leads, set it to One. A buyer who fills out the same form three times is still one buyer.
- Conversion window. Google defaults to 30 days and allows up to 90 for Search, depending on the source. A buyer who books a demo three weeks after the click still belongs to it, so set leads to 90 days.
- Attribution. Leave it on data-driven, Google's default. Last click is still available; the older rule-based models are gone.
Then clean house. A conversion that fires on every page view or every button click teaches the bidding to find visitors, not buyers. If an old account counts "pricing page viewed" as a primary conversion, demote it before the first new campaign launches.
Your CRM Knows Which Sign-Ups Became Real Prospects. Google Ads Hears Nothing Until You Send It.
The website can only report that someone signed up. Your CRM knows what happened next: whether sales qualified them, whether the demo took place, whether a deal opened and what it was worth. Google Ads learns none of that unless you send it back.
For businesses outside Google's sensitive categories (health, debt relief and similar), Google's preferred route is enhanced conversions for leads. When the lead form is submitted, the tag captures the email (and phone, if you ask for it), hashes it, and sends it to Google. Later, when your CRM marks that lead qualified, you upload the same hashed email with the new stage, and Google matches the two. Google is blunt about the older method: "Offline conversion import is a legacy feature, and it doesn't have the durability features that enhanced conversions for leads offers." If you capture the click ID (GCLID), send it too; Google asks for it where you have it.
HubSpot and Salesforce, the two CRMs Google builds into Data Manager, connect differently:
- HubSpot. Google's built-in connector, set up in Google Ads Data Manager, builds conversion actions from HubSpot's Lifecycle Stage field, and every rule you set has to include it. If you want the deal's dollar amount as the conversion value, HubSpot's own ad conversion events can send "the Deal amount" from the associated deal. How many of those events you get depends on your Marketing Hub tier.
- Salesforce. Google's connector reads the Opportunity Stage field and the Lead Status history, so "Opportunity Stage becomes Closed Won" can be its own conversion action. You can map any Salesforce value field to the conversion value. Field history tracking has to be on for the fields you use.
- Anything else. Since June 15, 2026, a new custom upload pipeline has to use Google's Data Manager API, because the Google Ads API stopped taking new offline-import users. File uploads and the built-in connectors still work.
There is a clock on all of it. An enhanced conversions for leads record sent more than 63 days after its click gets thrown away, and the cutoff for a click-ID record is 90 days. A software deal that takes four months to close never reaches the bidding, however carefully you upload it. Send it anyway. Just don't bid on it.
Google Wants 15 Conversions a Month on the Stage You Bid On. A Qualified Lead Gets There Long Before a Paid Plan Does.
With every stage flowing back, pick one for the bidding to chase. Google is specific about what makes a good one. Pick a stage that logs 15 or more conversions a month, that buyers usually reach within a week of clicking, and keep it to that one stage. Google warns that bidding toward several stages of the funnel in one strategy "can be duplicative and lead to suboptimal performance."
Run the stages through those tests:
- The sign-up passes on volume and speed, and fails on meaning. It is the stage the first section of this chapter warned about.
- The paid customer or closed deal passes on meaning and fails everything else. It is rare, it often lands weeks or months after the click, and a deal that closes past the 63- or 90-day window never arrives at all.
- The qualified lead or held demo is usually the earliest stage that predicts revenue while still happening often enough and soon enough for Google to learn from it.
So the qualified lead (or the held demo, if that is how your sales team qualifies) goes in as the primary conversion. Closed-won comes back too, as a secondary conversion, so you can report revenue by campaign and keyword even though it isn't steering.
One caution for small accounts. If you sell into a narrow niche, even qualified leads may never reach 15 a month. That doesn't change what you track. It changes how you bid, and Chapter 7 covers setting bids by hand while the volume builds. Chapter 3 turns these stages into what a customer can cost, and Chapter 15 covers products that run a free trial and a sales demo side by side.
Next: "What Is a CRM" Wants a Definition. "CRM for Small Business" Wants a Product.
Now the account learns from buyers instead of browsers. Chapter 2 sorts software searches by how close the searcher is to buying, and shows where the first dollar belongs.
Every chapter, from tracking to brand campaigns, competitor campaigns and the rules for free trials, is on the guide's home page.
On the software accounts we run for clients through Google Ads management, the CRM link goes live first and the keyword list comes later. Doing it yourself? Open your conversion actions today and check which one is marked primary. If it's the sign-up, you know where to start.
