Simple but effective SEO Tool to use

I have been using the Yoast SEO tool since I built my WordPress website 8 years ago. It is an easy and effective way to optimize pages and posts without having to have technical know how. I have referred several colleagues and clients to the tool as well. One colleague told me it garnered her thousands of dollars in sales after she optimized one of her pages. I too find it brings in good traffic and is very easy to use.
