Duplicate Title Validator

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

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. 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.

Reviewers say it does what it promises, with a few asking for faster checks, clearer notices, and slug duplicate handling.

   Hi I really want this plugin, But before that I need some information about it.. Does it work well with 4.2.4? And how does it verify the title everytime its entered? Does it send a query to check all the post titles each time? And if that is the case. Doesnt that slow down the database and the website?

   Update: updated my rating based on the changes made by plugin author. The plugin works nicely and does exactly what it promises. However, the notices are not very understandable, probably due to language barrier. I would be happy to help the author improve notices. Another issue is that the plugin can help prevent duplicate post titles, but it can not help prevent similar looking URL slugs. For example if a user entered a duplicate title ‘Once Upon a Time’ their second post will have a URL slug like: http://example.com/once-upon-a-time-2 It would be nice if this could be prevented as well. Alternately, the red notification can also include a warning about reviewing the URL slug. Thanks
