How to track button click in iframe?

Question

Google Analytics

I give contextual advertising, a form is inserted into the page in an iframe. How to calculate the click of the submit button of this form as a metric or analytics.

Answer 1

There are a lot of difficulties with analytics in frames.
If contextual advertising is in AdWords, then the easiest way is to insert the conversion code on the "thank you for filling out the form" page.

Answer 2

Yes, pasting the code on the thank you page is a good solution.
Another option is that when the button is pressed, a page is pulled out, for example, the same thank-you.html, but it does not load visually, but is simply visible in the code. if you look. If you just put Google Analytics tracking on this page and add it as a goal, this will be the conversion indicator for clicking the button.

Answer 3

Use Post Message.
