Do keyword research prior to writing any of your content. There are tools out there like
Google Keyword Planner or
Ahrefs that allows you to search for keywords (or keywords with like-terms) and find keywords that generate a decent amount of traffic and aren't too difficult to rank for. I am currently testing this out on my own blog, and seeing if I can rank for several smaller/less competitive keywords.
This will ultimately start driving more traffic to
my site, while building up a higher domain authority (making it easier to rank for the more difficult keywords).
