Do you block Googlebot from accessing Javascript, CSS or other important parts of your site’s code?

This used to be no big deal. But today, this is a VERY bad idea. Unless Google can fully crawl your page, they can’t tell its mobile-friendly or not. And if they’re not sure it’s mobile-friendly, good luck ranking in the google mobile-first index.

How do you know if this is an issue?

First, check out your robots.txt file. This tells Googlebot to not crawl or index certain parts of your site. This file is usually found at site.com/robots.txt. You can also see it inside of the Google Search Console.

While you’re there, click on “Google Index” —> “Blocked Resources”. This will let you know if you’re blocking Googlebot from crawling certain parts of your site.

If you’re not blocking anything important, you’re set.
