Plenty of easy-to-understand info is available to describe everything Yoast-related. So I have a very strong sense of what my plugins are supposed to be doing. In other words, you don't need to be overly tech savvy, just be smart enough to look at all the information as it becomes available. Never a complaint!

I use the Yoast SEO plugin on two of my websites and to me it's like a reminder of general guidelines and best practices in the SEO world. Very user friendly, so good tool for beginners and non initiated or for more experienced people with less time to spend on their content but see some value in search engine optimization. Quite inexpensive tool

I like the fact that it analyses the readability of your text and tracks the use of your keyword. It's mostly accurate in highlighting what it considers as in need of improvement about your text (passive voice, too many words in a sentence, etc.).
