Which WordPress Plugin Should You Avoid?

If you are a beginner on WordPress and don’t have a consistent audience yet, I would highly recommend you to avoid installing the Forms plugin, for instance, WPForms Lite.

For example, you might want to add a Contact Form plugin on the ‘Contact Us’ page of your website so people can contact you for queries and feedback. But this might lead to a lot of spam comments instead.

Website ss

It is much better to simply mention your email address so only legitimate users can contact you. I have done the same on my personal blog.


So, these were some of the Best Free WordPress Plugins that should be installed on every WordPress site for enhanced security and performance. If you wish to implement additional security on your website, here are a few WordPress Security Tips that you can follow!
