This is a rant. But a rant with a solid basis: Get rid of those popups, they are hurting your website! It’s not a stretch to argue that readers don’t like popups on websites. (They’re seriously annoying!) So Google made a call that websites that use pop-ups and interstitials should rank them lower. Just think about it – if your website has a popup opt in form, and your competitor does not, you may be ranked lower because of it.
Maybe when they were new, they were effective. (You know, 5 years ago.) But now? They are basically ignored. I specifically hate those sites with popups that appear every few seconds on every page – they’re like irritating sales girls!
What can you do instead? Place your opt-ins or call to actions strategically throughout your site – on your homepage, sidebar, after your content, or before you content. If your pitch is effective, people are going to want to subscribe. You don’t have to shove it in their faces every 3 seconds. Other than music that autoplays, nothing else makes people leave your website in a hot second.
