Questions

Does hook rate apply to image ads?

No. It needs video views, so it is calculated only for video ads.

What counts as a good hook rate?

As a rule of thumb in Cofoundr, above 25 percent is strong and below 15 percent is weak. Compare against each account's own norm.

Can it pause weak ads?

Only if you turn on the optional rule. By default it only diagnoses.

Where does the data come from?

From your connected Meta ad accounts, using the same date window as the dashboard.

Does it work for Google Ads?

Not yet. Cofoundr works with Meta Ads (Facebook and Instagram) today.
