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 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.
Creating new book taxonomies is so easy it’s up to you to decide which and how many taxonomies you want to add.

Use listings embedded in pages to make your book reviews accessible by title or taxonomies such as series or author. 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 its 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.

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

I am getting a 404 page when I visit a book review

Try flushing your permalink settings. Visit Settings -> Permalinks and just save without changing anything. Also, make sure you are using the singular form of the word you are
using for your custom slug. So, instead of “books”, use “book” or instead of “lists” use “list”.

I have no particular knowledge of coding, but I was looking for a plugin to create a sort of collection of books: a bibliography and, at the same time, a library. I'm not interested in selling and things like that. Additionally, I needed to be able to automatically import a book's details via its ISBN. Well, even though this beautiful plugin was probably not created for this, it works perfectly for my needs. There really must be a lot of work behind it. It takes a bit of patience to understand certain mechanisms (I'm not an expert in coding) and the documentation is minimal (but I don't reproach the author of the plugin who is always present on the support forum to resolve any doubts). The plugin can probably still improve, but the project is mature and very useful for those who want to deal with books and collections. My suggestion, for what it's worth, is to release more general documentation on the use of shortcodes and make more customization of rendering possible (although I suspect that I'm probably the one who doesn't have much expertise with CSS and such things). Thank you so much for this wonderful plugin.

For a free book review plugin, this is the best one out there. It's not perfect (maybe "unfinished" is the better word to use) but you still can't go wrong with it.

You can use this plugin to sell paper books, ebooks online/offline, you can even use your creativity to evaluate products to make money with affiliate marketing… A big thank you to the Plugin author for providing the world's wordpress fans with a great Plugin!

I'm starting my book review site and have been looking for the perfect plugin to help me organize it. I have tons of reviews already that I'm slowly migrating to my new site so I've been looking for a plugin to speed up the process. I'm amazed at how intuitive and easy to use Recencio is. I don't know much about coding so I rely on plugins to not break my site. Recencio was easy to install and even easier to set up. It has every single feature I was already doing manually and more. And the creator of the plugin is so quick to lend a hand when needed! I've never come across a plugin with so much tech support in a matter of minutes. I was stuck trying to change the appearance of one of my pages and Kemory patiently answered my questions and guided me to make the changes I needed in a matter of minutes. Truly an incredible plugin and I will be recommending it to all of my blogger friends.

I tried it years ago and was impressed. I'm making a new site for my books and didn't even think of any other option. It's absolutely perfect for index cards or book reviews. Thanks a lot!

This is already the best plugin of its kind, and with a few tweaks and more customisation options, it will be even better. It's an excellent plugin and the developer is clearly passionate about it. The level of support is great also. Thank you.
