ChatGPT Ads vs. Google Ads vs. Meta Ads: What €100 Actually Delivered for One Business

Is it worth advertising on ChatGPT, or would I get better results spending my budget on Google Ads or Meta Ads?
Rather than relying on industry averages, we decided to examine the actual results from one of our clients.
At izivizi, we ran advertising campaigns for the same education business across Google Search Ads, Facebook and Instagram, and ChatGPT.
The campaigns promoted the same business, with similar offers and messaging, and directed visitors to the same website.
We analyzed 34 days of advertising data to answer one simple question:
What does €100 of advertising actually deliver on each platform?

Google Search Ads delivered the lowest cost per click and the lowest reported cost per conversion.
Meta Ads came surprisingly close on conversion costs, despite its higher cost per click.
ChatGPT Ads delivered traffic at a cost comparable to Meta, but its reported conversion cost was substantially higher.
That last finding deserves a closer look.
How does ChatGPT Ads performance compare to Google Ads and Meta Ads?
One of the most interesting observations wasn't how much a click cost. It was what happened after that click.
Our average cost per click was:
Meta Ads: approximately €0.57
ChatGPT Ads: €0.61
A ChatGPT click cost only about 7% more than a Meta link click.
At first glance, that doesn't seem like a dramatic difference.
But when we compared reported conversions, the picture changed.
Meta's cost per lead was approximately €12.60, while ChatGPT's cost per reported conversion was €70.62.

That made a reported ChatGPT conversion approximately 461% more expensive than a Meta lead.
The lesson is straightforward: similar traffic costs don't necessarily produce similar business results.
A platform can generate affordable clicks without generating equally affordable conversions.
What €100 delivered on each platform?

To make the comparison easier to understand, we normalized the results to a €100 advertising budget.
Google Ads: 8.85 reported conversions
Google generated 92.97 conversions from approximately €1,050 in advertising spend. The vast majority were recorded as lead-form submissions.
Meta Ads: 7.94 reported leads
Meta generated 41 Pixel Lead events from approximately €517 in advertising spend.
ChatGPT Ads: 1.42 reported conversions
ChatGPT generated seven reported conversions from approximately €494 in advertising spend.
These figures describe what the advertising platforms recorded, not necessarily the number of unique or qualified customers acquired.
Nevertheless, the difference is substantial enough to warrant investigation.
