Google Ranking Factors
This will be a very short post. I've been trying to figure out why my site isn't showing up in search results (I've looked at upwards of 30 pages of search results - no sign of my site) and stumbled across this: www.backlinko.com/google-ranking-factors.
This is a pretty long document, but I learned quite a bit on my first casual perusal.
Hope it is useful!
