Case Study

"What am I missing?"

As we outline here, privacy-first browsing neutralizes 72,000+ cookies, pixels, scripts, tags, and trackers. This affects over 800 martech companies, many of whom are household names.

This state of affairs impacts analytics data in profound ways. Our research suggests we may only see 11% of available events. That's not a typo. And it means that, in some cases, we could be wasting $0.89 of every $1 we spend on our marketing tools.

This tweet made us wonder ...

"How much data do analytics platforms like Mixpanel and Google Analytics typically miss? How much can Confection help users recover?"

Let's Find Out

So we ran an experiment. It went like this:

We have hundreds of videos embedded on company-specific landing pages.

Each video is hidden from Vimeo, can be embedded and played exclusively here (@, and only appears on one page.

Confection Impact Videos @ Vimeo

Bottom line:

If someone plays one of these videos, they do so @ and nowhere else.

Vimeo tells one story.

Between 1/29 and 2/4/21, visitors to watched 16 videos on 16 pages 46 times.

On average, visitors watched 56% of each video. Each play in the chart resulted in the visitor watching at least 15% of the video.

Google Analytics tells another.

Between 1/29 and 2/4/21, Google Analytics logged just 9 relevant pageviews.

Four of these pageviews logged no time on page (0:00:00).

A video play, like any page interaction, would trigger > 0 values. As such, it’s possible none of the the 0:00:00 pageviews are associated with video plays.

Assuming a 1:1: relationship between pageviews and video plays ...

We’d expect to see 46 pageviews in Google Analytics. At minimum, we’d expect to see 16.

However, at best ...

Google Analytics was only able to log 20% of the relevant events. At worst, it was only able to log 11%. In either case, 80-89% of events went untracked.

We know what you're thinking: "What about bots?"

"Did Google Analytics filter that traffic out? Could that explain the discrepancy?"

The short answer is, "It's unlikely." A longer answer follows:

No system is perfect, but uses Cloudflare's various bot management tools to keep this kind of traffic at bay. Combining these tools with Vimeo's privacy resources gives us a reasonable degree of confidence that Vimeo Analytics captured real video plays that took place during real pageviews by real people.

So why is Google Analytics is missing 80-89% of the same pageview events?

We believe those visitors used privacy-first browsers, tools, or settings that blocked scripts like and Blocking these scripts on the browser level would prevent transmission of pageview events from to our Google Analytics account.

See This in Action @

After analyzing hundreds of different sites, we've discovered seven different Google Analytics scripts neutralized by privacy-first. And we've found at least one of these scripts on 72% of the sites we've analyzed. In other words, while the 80-89% figure did surprise us -- we expected 20-25% -- this is a very common issue. Like Mixpanel and the other data gathering applications we include on our demo, Google Analytics is heavily impacted by privacy first.

We have found two blocked Vimeo scripts, but these attempt to gather information about the page on which the video iframe is embedded. The iframe and video inside it are unaffected.

Why is this?

Browsers treat the video iframe itself like a top-level browser window. This means that, in essence, when played via iframe, Vimeo video embeds are just sending data directly from to It's as if the video itself is playing on instead of, and this sort of first-party data transfer triggers far fewer privacy-first alarms.

We thought we were living in an environment of 20-25% waste.

Based on this, it’s actually 3x that (or more). So much for waiting until 2022.

“What are the financial implications of this?”

Google Analytics is a free platform.

Imagine this is Mixpanel, Segment, &c. You're suddenly wasting $0.89 of every $1 spent.
