Top SaaS sites and Google Ads conversion tracking: 66.7% count a click, page load or login
TL;DR. 62 of 93 top SaaS sites with a Google Ads conversion (66.7%, 95% interval 56.6 to 75.4%) send one on a click, a page load, a login or a trial end. Across all 684 B2B SaaS sites with Ads conversions in the 5 Nov study the share was 53.4%. The 93 here are part of that sample, the top-ranked slice, so this is a read of big sites, not a new random draw. We saw the container, not the Ads account: a conversion we flag may be secondary and harmless to bidding.
What did the 93 top SaaS sites send?
Share of the 93 sites with each pattern, next to the 684 B2B SaaS sites with Ads conversions from the 5 Nov study. A site can show several patterns, so rows overlap.
| Pattern | Top SaaS (n=93) | 95% interval | All B2B SaaS (n=684) |
|---|---|---|---|
| Any noise trigger | 66.7% 62 of 93 | 56.6 to 75.4% | 53.4% 365 of 684 |
| Button or link click | 46.2% 43 of 93 | 36.5 to 56.3% | 33.5% 229 of 684 |
| Page load (every page or a plain page view) | 34.4% 32 of 93 | 25.5 to 44.5% | 27.9% 191 of 684 |
| Duplicate conversions | 30.1% 28 of 93 | 21.7 to 40.1% | 22.4% 153 of 684 |
| Login counted | 12.9% 12 of 93 | 7.5 to 21.2% | 9.8% 67 of 684 |
| More than 8 conversion actions | 37.6% 35 of 93 | 28.5 to 47.8% | 23.8% 163 of 684 |
| No conversion value on any action | 62.4% 58 of 93 | 52.2 to 71.5% | 71.9% 492 of 684 |
| Enhanced conversions on | 51.6% 48 of 93 | 41.6 to 61.5% | 38.6% 264 of 684 |
Intervals are Wilson 95%. Where the interval holds the all-SaaS share, we can't say the top sites differ. Clicks and the share with any noise trigger sit above it; the share with no value sits slightly below it.
Do bigger sites send more conversions?
The median top SaaS site with an Ads conversion sends 6 conversion actions in its public container, against 4 across all 684 B2B SaaS sites. More actions means more places for a click, a duplicate or a missing value. The pattern fits the 5 Nov study, where Tranco top-10k advertisers had the highest noise rate.
What does each pattern mean?
- Click. The conversion fires when someone presses a button or link, not when a form is accepted. Fix: button click conversions.
- Page load. The conversion fires on a page view of a page that is not a clear success page, or on every page. Fix: conversions on every page.
- Duplicate. The same label sits on two tags, or one trigger fires two labels. Fix: duplicate conversions in GTM.
- Login. A login or account page is a conversion. Fix: login and trial conversions.
- No value. No conversion sends a value. Fix: conversion value for lead gen.
What can't we see?
- Primary vs secondary lives in the Ads account. A click conversion set to secondary does not drive bids.
- Server-side tags are not in the public container, so real rates are likely higher.
- Cause. Large sites run many tools and agencies. These are shares of what we saw, not proof that size causes them.
- Sample. The 93 are not random. They are the top-ranked slice of a list-built sample, and they are part of the 684 they are compared with, so the two columns are not independent.
Method
The 200 best-ranked sites (Tranco list JZPGY, all in the top 10k) of the 5 Nov B2B SaaS segment, read again on 12 Nov with the same static read: homepage, /pricing, /signup and /demo (robots.txt respected) and the public googletagmanager.com containers. 173 loaded, 2 were dropped as duplicate containers, n = 171. 93 (54.4%, interval 46.9 to 61.7%) send a readable Google Ads conversion. Numbers were recounted from the raw scan files by a second script. No forms, logins or bot evasion. Full rules: method. All-site results: the study; all B2B SaaS.
