Post Volume Stats


This plugin looks at the volume of posts in each category, tag, the volume of posts per year, month, day-of-the-month, day-of-the-week, hour, author, number of words-per-post and the number of days between posts. You can specify a year and/or an author to just look at the post volume stats for that year/author. The bar and pie charts can be added to a sidebar with Post Volume Stats widget. Lists and line graphs can be exported to a new post to show the change in category, tag and custom taxonomy posts over the years. You can also export the “Compare Years” data into a CSV spreadsheet. The latest feature is the “Date Range” page which applies a date range to the data on the main page.

Thank you for your plugin its great! my petition is if you can give us the option to view a chart of posts volume by authors, and have the possibility to view a chart by months, or weeks to see which author is performing the best per week, month and year, would be awesome to have that chart view Thank you for your effort!

With dozens of authors and posts per day, this plugin gives a very nice overview of who does what and when.
