  • Shareaholic – Highly customisable and supports Share and Follow buttons for several social media platforms. Also adds a “Related Posts” feature if you need it.
  • Sharify – Adds beautiful and responsive sharing buttons to your website. Also comes with built-in caching support to reduce server load.

Contact Form 7 has to be the best in this category. It is easy to install, setup and use. It also allows you to add multiple forms to your website with AJAX and CAPTCHA support.



  • Ninja Forms – Neat form plugin with a drag and drop interface for easy creation of forms. Functionality can be extended using premium plugins.
  • Pirate Forms – Comes with built-in widget and shortcode support.

Updraft Plus is highly recommended to back up your site. You can back up to multiple locations, split backups or schedule automatic backups. Many more features are included as well.

Sucuri Security offers a wealth of security options such as Security Activity Monitoring, Malware Scanning, Blacklist Monitoring, and Security Hardening. It is probably the best plugin for monitoring your site without slowing it down.

  • All in One WP Security and Firewall – Gives your site a “Security score” based on the options you have activated on your website and helps you improve on that score.

The page builder plugin is useful if you are not technical and need to create custom layout for particular pages. Page Builder by SiteOrigin is the most advanced free page builder plugin for WordPress. Period.


There are a few plugins in this category.

WP Smush helps you to reduce your image size (by stripping unnecessary information from your images without quality loss) and make sure your site loads faster. Alternative to this include EWWW Image Optimizer and Kraken Image Optimizer


Regenerate Thumbnails is another image optimization plugin that helps you regenerate thumbnail sizes for image attachments after you altered thumbnail dimensions.

BJ Lazy Load does not optimize your images. In fact, it hides all your images and only loads them as the user scrolls through the page. This plugin can help you save bandwidth and make sure your website loads fast. BJ Lazy Load supports responsive images as well as iframe (such as Youtube embed, etc.).

Yuzo – Related Posts is highly recommended as it can display related posts to your stories with different features of text and image size. Best of all, it doesn’t slow down the site.



Notable mention: Many consider Yet Another Related Posts Plugin (YARPP) to be the best post related plugin with one of the most complete algorithms to find related posts. The con is that it can be very resource-intensive for a heavy site, and that’s why we don’t rever to it as the best here.

Caching your site is the best way to make sure your site loads fast and the server does not go down when there is a sudden spike in traffic. W3 Total Cache is probably the most advanced (and free) caching plugin available for WordPress.



  • WP Super Cache is the next most well-known caching plugin after W3 Total Cache. If you just need a simple caching mechanism, then WP Super Cache is strongly recommended over W3 total cache
  • Broken Link Checker – Monitors the links in your posts and notifies you if there are any broken links.
  • Edit Flow – Improves organization of your website’s contributors and offers a calender to view scheduled content.
  • WP Mail SMTP – Reconfigures the native WordPress mail function to use SMTP and make sure all your outgoing emails reaches their destination.
  • JetPack – Brings the best parts of WordPress.com to self-hosted WordPress. Highly recommended, though it can be overly bloated.
  • Askimet – Prevents comment spam on your website.
