Forms for Mailchimp by Optin Cat – Grow Your MailChimp List

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 · 62% 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.

   Your products are great but I didn’t have a great experience with your pre-sales. I asked a question regarding the pro version of your soft and didn’t get any answer several weeks later. but as of the optin cat, I’m really happy with it. the landing page cat as well for simple landing pages. sometimes it’s all that you need 🙂
