I created this tutorial to help you understand how much Yoast can help your SEO. It's just like having a SEO professional standing behind you while you write. My personal experience with Yoast has been so good that it made me want to help others realize the power behind this plugin.
If you have not installed Yoast go do it now! Click on Plugin then click Add New. Type Yoast SEO into the search box. Install and Activate, now you're ready to roll!
After you have installed and activated Yoast you will need to set up your Titles and Metas before you being to create or update posts and pages.
Go into your WordPress dashboard. Click on the SEO to open the drop down menu. Then click on Titles and Metas.
It will open a page with these options at the top. Click on Post Types.
Now you will see the options below. Set it to Index Meta Robots, Hide Date in Snippet Preview and Show Yoast SEO Meta Box. Then scroll to the bottom and Save Changes.
You will also see a Help Center on every section of your Yoast Plugin. If you are ever unsure what to do click on it for further instructions.
Now it's time to start writing!
