Certain uses for WordPress, such as a showcase or gallery site might call for a user rating system. You may also want to implement one in your blog just to see how you improve over time and how it affects your user’s experience.
A popular plugin for serving up star ratings to your visitors is WP-Post Ratings. Its easy to display the rating form with a function, and you can customize the rating images in a variety of colours and styles. Also, WP-Ratings allows you to filter the ratings by different groups like by author, category, month, or year. This would typically be the first plugin you would find searching through WP.org for any sort of rating system, but dig a little deeper and you might unearth some of these useful gems.
Vote the post – This is a simple plugin that doesn’t nag at you with a lot of options. It offers a simple, user-friendly rating system with votes like “Below Average”, “Needs Work” ,”Average”, “Very Good” and “Excellent”.
Post Star Rating – This plugin installs quick and easy. It shows the highest rated posted for the month. It also lists the most popular posts at the moment and moves them up and down the list in realtime.
I personally use Outbrain because it doesn’t interfere with Disqus…found that Post Ratings did.
I found that most readers don't even comment so a rating system is too much for readers. Just keep them reading, subscribing and commenting and I think you will get enough feedback with targeted criticism or praise.
Maybe it is just my niche though!
That would be very helpful for my blog. In fact, it will only give an idea about what preferences readers are making in my site. Thanks for the idea. Would love to try post rating thing.
