Copyscape Premium

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 · 91% 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.

A small install base leaves thin data to model from. The range spans more than 10x because wp.org publishes install counts as broad bands, and conversion and price compound on top. Read the midpoint as an order of magnitude, not a valuation.

   The plugin is not working. I paid for the service, checked all the settings. After pressing the check button, the page is updated, but nothing changes, and the limits are not written off. This topic was modified 1 year, 5 months ago by Просування сайтів.

   I personally installed the plugin in my site to detect plagiarised content that i did not notice before. and well just for 10$ I got almost unlimited credits to check for it on product and posts pages. The tool is perfect detecting spam. The only thing is that it also autodectects the same website content as duplicate. And also after saving Twice, The plugin conflicts a little with wpml plugin and changes the language of the post which damages the page. Though i need the plugin and still works. I hope others check this great tool to fight the latest google spam updates more easily. and I hope the author can do a great update for this great plugin!!!!

   You need to register and pay for the API, no complain, this is clearly said before even installing, so all good here (user complaining on that is unfair) The plugin is very easy to install and use Admin and user setting are very good Many options to check plagia when user want … but it is pushing to sell more 😉 … and that can cost very quicly several dollars per articles if you don’t pay (pun intended) attention So please, copyscape team: – optional: by defaut, deactivate all automatic checks. Users may select them back – nice to have: do indicate the remaining credit on the account in the post edit page – a must: do indicate how much credits it will cost to check, BEFORE CHECKING

   This plugin is a worthless. There is nothing free, not even one trial search. When you go to there website they sell credits, but they don’t tell you what the credits are worth or how many searches you get. These people are not transparent and only want your money without even telling you what they will give you for it. They should be banned from being on wordpress.

   when i click copyscape check on post page, it shows “Copyscape was not able to check your post – you have no search credits remaining.”, so i must pay this plugin if i want to use it. Not much like this. I thought it’s free.

   If you concerned about duplicate content and Google rankings then you need some type of plagiarism checking software. I found CopyScape to be highly recommended, inexpensive, easy to use and multiple capabilities. I had a little trouble with the API, but I realized I was capitalizing the first letter on my user name. (Don’t capitalize the first letter of your user name.) Once I figured that out it works great! The WordPress detail page states CopyScape has not been tested with the latest version of WordPress(3.9.1), but I’m not having any problems.
