While using the All-In-One-SEO plugin my website was ranked #1 on the first page of Google. But because my hosting provider said that the AIO-SEO plugin was resource intensive they recommended I remove it and use another plugin. So I installed this Yoast SEO plugin. The Yoast SEO plugin caused my site to move down to #9 on the first page of Google.
I installed Yoast on another site at the same time and that site is not searchable on Google at all. This Yoast SEO plugin is absolutely horrible.
