I don't use keywords on the WA platform. As far as I'm concerned, what I write here is for the consumption of the WA community. Nobody else (except me).
I'm going to split in this case with my opinion, I agree with the wealthy affiliate training that keywords are important and that they have the potential to increase rankings in search engines. However I am also going to agree with Mitch on this one and say that when your content is discovered if the reader realizes that the content is from the heart and your true words they are more likely to believe what you say, and then become a true loyal visitor.
It's good to get used to using keywords all the time. I don't think I've been using it for writing my blogs here at WA except in writing content on my website.
