SEO never stops evolving.
Just when you think you have all the facts straight, you learn something you were missing in your strategy, or Google updates their algorithm again, or you realize you’ve been slightly behind the curve.
So far, in 2018 alone, there have already been 12 major Google algorithm updates — confirmed and unconfirmed — and that’s not counting the regular, small updates they do daily.
The year isn’t over, either.
Keeping up has to involve keeping your finger on the SEO pulse, reviewing your strategy regularly, and implementing new best-practices in smart ways.
