TestSpy🔎 is a Chrome Extension that tells you what A/B tests and Personalization campaigns are running on a web page 🤓
IT’S CURRENTLY PENDING APPROVAL IN THE CHROME WEB STORE 🙂
Why would anybody want to know that?
I can think of a couple reasons if you’re a marketer or product owner:
Figure out what kind of experiments your competitors are running. Of course you won’t just go copy them, but it doesn’t hurt to know what they’re testing … and monitor to see if they get a win.
Debug your own pages. If you’ve got a lot of pages and a lot of campaigns live, sometimes it’s confusing to figure out what’s running where.
And if you’re an agency or freelancer, here’s a thought:
Analyze and critique experiments as part of your sales process. There are tons of people out there paying for A/B testing tools but not using them – or using them in trivial ways. Now you can know exactly what they’re trying to test before reaching out.
How’s it work?
You install it TODO_LINK_TO_EXTENSION here.
Then just visit a web page and click the icon. If a test is running, you’ll see info about it:
TestSpy🔎 currently supports the following tools:
- Google Optimize
- Adobe Test & Target
These three make up the majority of the market!
So if someone’s running experiments, there’s a very good chance you’ll detect it. (However, if you don’t detect an experiment, that doesn’t prove that they’re not running one. They could be using one of the less popular tools.)
Google Optimize anonymizes experiment and variation names by default, so all you’ll learn is that a thing is running:
If you want to reverse engineer the experiment to find out what all the variations are, your best bet is to visit in Incognito repeatedly and visually inspect the page for differences. But at least TestSpy🔎 tells you where to look!
How do I know you’re not stealing my datas?
TestSpy🔎 is open source. You can view the code on GitHub.
(Also I promise I’m not stealing your datas, if that helps.)
It’s not working! I need help!
Please reach out and I’ll take a look.
