FAQ

About the extension.

Anything else: hello@overt.cc

Is the extension free?

Yes. Counting, filtering by format, A/B variants, languages and the download are free, with a free Overt account. The account is free for up to 5 companies followed, no card required.

Do I need an Overt account?

Yes. The extension signs in with your Overt account, so your watchlists are the same in the extension and in the web app. Creating one takes a minute and asks for no card.

Will the extension add Google or Microsoft ads?

No. The extension is built for LinkedIn Ads and stays that way: it does one thing where you already look, and does it well. Google and Microsoft ad activity lives in the Overt web app, next to LinkedIn, for every company you follow.

What’s in the download?

A ZIP with the ads you had on screen, as an HTML sheet and a JSON file, grouped by language and then by format. Filter first, download after: the file holds what you see.

Does it need access to my LinkedIn ad account?

No. Overt never asks for your ad accounts, or anyone else’s. The extension reads the LinkedIn pages you open yourself.

Does Overt see the websites I visit?

No. Recognizing the advertiser behind a site, and the ad trackers it runs, is checked on your device. The addresses of the sites you visit are never sent anywhere. Details in the Privacy Policy.
