Recencio Book Reviews


Recencio Book Reviews is a powerful and very flexible tool for managing your blog’s book review collection. It was designed with the book reviewer in mind and was built to be fast, easy and customizable.
The plugin even provides book reviewers the opportunity of earning residual income via adding their own book purchase affiliate links.

This plugin adds a custom post type for book reviews to your site. You can publish book reviews as standalone posts or include them in your normal posts and pages.
Organize your book reviews in any way you like. The plugin comes with some basic predefined taxonomies such as book author, genre, series, and publisher. As creating new book taxonomies is easy it’s up to
you which and how many taxonomies you want. Use listings embedded in pages to make your book reviews accessible by title or taxonomy name. Or use one of
the custom widgets to create tag clouds or top ten lists.

Of course you can use all the WordPress goodies you know from posts on book reviews as well: images, videos and comments.
Despite it’s simplicity, it’s giving book reviewer, administrators, designers and developers all the freedom to adapt the plugin to their needs. Features you don’t
need can be deactivated and are hidden from the UI. You can even create your own book review template files to gain complete control the look and feel of book reviews.

And, all of the above is SEO friendly by way of validated JSON-LD metadata for the ‘Book’ and ‘Review’ schema markup.

Best plugin for book reviews


Before testing Recencio plugin I tried many others but this is the best one I found.
The developer is really helpfull and constantly improving the plugin.

It offers all what you need to create a site for book reviews which is what I was looking for and offers quite a lot of flexibility to create a really nice style for your blog.

Great work and support

Great Little Tool

I just started an author page and wanted a book review plug-in. This does everything I need. Pulls info on books from Google Books or Goodreads, so I don’t have to input all the bibliographic info. Finds the book cover for inclusion. Has a star rating system. And looks so professional when it’s completed. Makes book reviews a breeze…now if it could just read the books and write the reviews for me! Just kidding. Great support also. Totally responsive. Thanks for developing this.

Great plugin

This plugin is exactly what i was looking for to use in my site and the support the author gives is 5 stars also.
