ExtraSpace WordPress Plugin

WordPress Plugin · Slide-In Side Panel

Guide your visitors to where you want them to be.

ExtraSpace is a WordPress plugin that opens up a brand new space on your site: off the screen. A little tab on the right-hand side of your screen slides open a single, powerful message that you want to get across. Launching a product? Exhibiting at a trade show? Running a fundraiser? ExtraSpace gives you the space you need to let visitors know about.

Behind the scenes, your ExtraSpace is an open HTML block. Anything you can with an HTML block in WordPress you can do with your ExtraSpace. That includes shortcodes. And shortcodes means you can do anything.

Use ExtraSpace Pro on Unlimited Sites

ExtraSpace Pro gives you serious targeting power. With its natural-language visibility rules, you can pinpoint exactly who should see the panel and where it should appear. For example:

“Show when URL contains /events/ and visitor is logged out.”
or
“Don’t show on blog pages with the category lifestyle.”

The targeting engine alone is worth the upgrade. But here’s the part most plugins never offer: you can install ExtraSpace Pro on as many sites as you manage. Five sites? Great. Ten? Go for it. The only limit you need to think about is the combined monthly visitors across all your sites, not the number of installs.
