Part 1 of a new series Completing A SEO Technical Audit begins with a popular topic Page Speed WordPress Optimization. Its popular for good reason, in an article I note an example where a site ranks higher on mobile search than its bigger, higher DA competitor because of page speed.
I don’t usually use Jetpack and prefer Cloudflare for the CDN but in this site’s case I lacked access to the domain DNS servers which hamper Cloudflare installation.
Jetpack is a plugin of last resort, and I honestly don’t recommend it. Its broken more sites than helped in my experience.
