[Enhanced] Review Bar Plugin with Schema Review Output V4.0.8

Hello,

you may have come here from our other post, which now redirects to this one. With this plugin, we had the goal, to create a simple, yet powerful plugin to showcase Reviews. Free, reliable, and safely.

We were deeply annoyed by all the Freemium-Versions of Review Plugins for WordPress, and especially their old coding, when we basically just needed a small, simple Plugin structure. So we made it ourself with the Help of Perplexity Pro.

Great News! THIS PLUGIN NOW SUPPORTS AUTO-UPDATES. As of Version 4.0.3 this plugin will update automatically in your backend. Just activate Automatic Updates in the Plugin Section of your Backend.

You can download Version 4.0.14 Enhanced (December 11th 2025) here for free.

To use this plugin, just download and install on your WordPress Installation. What this Plugin does:

1. Adds meta boxes in the Post Editing Screen
2. Fills the data into a shortcode, that appends the review to the end of the post
3. Uses an intelligent filter to detect the SKUs structur (ISBN, ISBN-13, etc.)
4. The Review Bar is colored, based on your rating. From 0 to 30 red, 31 to 50 orange, 51 to 75 yellow, 76 to 100 green.
5. Create a Rich Snippet Schema Output
6. Display multiple criteria for your review (f.ex. product design, ingredients, etc.) and rate each one
7. Mathematically outputs the correct rating based on all criteria rating
8. Uses the featured image as the display image
9. Uses the post excerpt as the description
10. Adds additional user information for Google
11. Checkbox to disable the plugin on a per-post basis

To use on posts:

Fill the following fields on your Post Edit Screen:

Value: Rating in % (0-100)
Price: Accepts , and . / All currencies available
Brand: Add the Name of the Brand
SKU/EAN/IBAN: Enter the barcode

If everything is filled in, on your frontend it will show a valid schema output for a Review.
