SSL Zen — SSL Certificate Installer & HTTPS Redirects

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 · 65% 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 declining trend compresses what a buyer would pay.

   Thank you very much, I am not a developer and working with WooCommerce was very difficult for me. But WooCommerce helped me solve everything in a very easy way. My site is ready to launch❤️ This topic was modified 10 months, 1 week ago by jannatcosmetics23.

   I was impressed with the support I received from the SSL ZEN team. I was struggling to obtain a reasonable SSL certificate that most web services charge outrageous prices for. I took the time to explore and found SSL ZEN through the help of the WP FORCE SSL PRO plugin. Both companies provided me with the suport with my understanding of how SSL works, how to save money with SSL certificates, and how to add them to C-Panel, and activate. Thank you for such a wonderful way to save money with SSL.

   This worked really well with Patmos hosting. Much easier then creating the certificates with the domain provider, then manually entering the keys
