Everyone needs to download Yoast SEO if you are using WordPress.  Yoast allows you to keep track of your SEO for each page/post that you create.  It will tell you what you should be doing and how to fix any mistakes that you made.  If you want to take your SEO a step further, you can download the Yoast Premium version.  If you want to get this version and other awesome plugins you can find them on Woocrack.  I have been using Yoast SEO on my Paintless Dent Repair website for a while now and I love it.
