Of course it does...we have people coming to the site looking for coupons. Our popup is a free eBook on how to save money using coupons. It doesn't popup every time, only for first time visitors.
Do we get 100% of the people submitting an email..of course not. Does anyone get annoyed, of course. Do we get higher conversion rates than without out..of course. That's why we use it!
If we judged everything by the cover, we'd never get anywhere. All the decision made on a site, need to be tested & measured. Hence what I was asking above in the article. If someone had data & ran some tests to suggest that a popup would have an effect on a popup, then that would be helpful information to have as I'm trying to address the drop in rankings.
