If someone visiting your site is using an ad blocker, it’s because they have enough internet experience to dislike automated ads…not advertisements from actual sponsors that you purposefully post, but the mostly irrelevant junk ads, like the ones I always see for “plus size” clothes that don’t go above an American medium.
A popup trying to force people to turn off their ad blocker is not going to get people to view the ads. It will just make them angry and they will leave your site and probably ignore links to your site from now on. Bonus, they might report you to Google or other search engines as “clickbait”. That’s what it is if you lure people to your site with supposedly informative articles as a ruse to serve them ads. So if you are a webmaster, and you’re thinking of installing one of these popups, don’t. It will kill your traffic.
