HollerBox — Fast & Effective Popups & Lead-Generation

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 87% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.

   Works without problem. Simple configuration.

   I installed the plugin and when trying to create my first popup I got the following error: “We could not load the editor because the defined template is no longer available.” I can’t create any popups. Very disappointing, I really wanted to try this.

   I was looking for something lightweight, simple, and, with an intuitive real-time interface for my client. This met the requirements. Here are some sugestions for improvement, though. Adding a template with a picture and button. Now, the only templates with pictures are the ones with sign-up forms. Adding an option to set a lifetime of a cookie when the modal window is closed, including a session cookie for example. Adding an option to open a link assigned to a button in a new window. Don’t load styles when no window is active. It can be simply done by checking whether any post of hollerbox type is published.

   I was hoping that this plugin was good… Luckily I only installed it on my staging page. That page got permanently spammed by a message that says “Attention: It looks like MailHawk is installed but is not connected to the MailHawk service.” I don’t have Mail Hawk and I don’t want it. But this message appears on top of all my sites in the admin area now, even after deleting the holler box plugin. Thankfully I can just renew my staging page and the spamming is over. But that’s real shady business!

   Garbage plugin, installed on 10 websites, after an update all popups stopped working. When I try to edit it says “We could not load the editor because the defined template is no longer available.”

   No. The software was riddled with bugs and modal popups that would display when the code threw an error. Really amateurish. I got a refund.

   Popup won’t hide even if the user clicks the “X” button. I have it set to hide if the user hides it. I absolutely HATE popups that won’t go away. And this one also doesn’t stop showing if I refresh, despite that the setting is not to activate until after 5 days.
