Every web site project will use plugins to compliment the core functionality of WordPress. These are our Top 4.

1. Yoast SEO
   Yoast SEO is the No. 1 Wordpress plugin for search engine optimization. Along with a properly coded WordPress theme, it is a cornerstone in the foundation of your WordPress site (assuming you want customers to find you, that is). The Yoast SEO plugin also makes it easy to effectively share your web site on Facebook, Twitter and other social media platforms. It generates site maps, hooks into Google Web master tools, and provides other essential features that every web site needs
2. BackUpWordPress
   Does exactly what it says, with the option to schedule backups for only files, only the database, or a combination thereof.
3. Wordfence
   The leading security plugin on the market, with over 22 million downloads
4. Smush Image Compression and Optimization
   Widely known as WP Smush It — or sometimes just Smush It or Smush — this plugin from WPMU Dev optimizes images as you upload them to WordPress. And since bloated images are the leading cause of slow web sites, this is one plugin you can’t afford to live without

There are many other plugins that we use widely, but these are part of every project no matter the scale or scope.
