How many keywords should you put in advanced settings?
Using AIOSEO, at the bottom of my web post there is the 'Advanced' option that lets me add 'Additional Keywords'
How many additional keywords should I be adding here, and what sort of keywords should I add to it.
Please no links on how to find keywords or the AIOSEO tour (cos it doesnt tell you). It's the advanced SEO keywords I need to know about.
