Yumpu E-Paper publishing

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 · 69% 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.

14 of the last 16 four- and five-star reviews came from accounts created within a month of posting the review.

Registering a wp.org account just to leave a review is common and often entirely legitimate. The share here is unusually high for the sample, so it's worth keeping in mind while reading the reviews.

   No response from author to critical error, by several support tickets. Plugin does not work. Do not waste time. It is dead.

   You are forced into signing up to a trial and then they charge your account after you have deleted the useless plugin and forgotten they exist. Developer website does not allow you to cancel your account, citing an error message. Complete fraudsters. Do not download this plugin!

   You need a paid account to use this. Misleading to say you only need a free account.

   Plugin description says required Yumpu account is free, but on entering API key from this free account get the error message “To use this feature, you must be a paid user” This seems misleading to me.

   Since months it doesn’t work. No answers, no support. All work and all words gone with the wind… This topic was modified 6 years, 6 months ago by Stephan Schmidt.

   I uploaded a Pdf on yumpu.com, apparently successfully. It was only during the upload process that I learned of the adverts to be put on the ePaper in the free version. I got the API and it was accepted by the WordPress plugin. However, the plugin did not list my Pdf from yumpu.com. I uploaded the same Pdf directly into the plugin, but it still did not list anything. I went to delete my yumpu.com account, but could not find a route to do so because it demanded a password, and I had signed up via Google and I so had never set a password. The yumpu.com profile change-password option demands the old password first, even though I am logged in. The login password reset email’s link simply goes to the yumpu.com home page, so I cannot set a password. Ah, that is while I am logged in! It does invite a new password if I open the email’s link in a private browser window… that’s a fail. Even now, with a password set, the delete-profile option fails: “Ooh no, something went wrong !”. How can I delete my yumpu profile?

   Not only does this plugin require registration on their website in order to get it to work, even just clicking on the link to add the API key completely rendered my admin access unusable until I restarted my browser.
