We write about a lot of fancy stuff on the Portent blog, such as server log analysis, advanced keyword research, and Tom Cruise. I want to address something that doesn’t have to be fancy: site speed.

These may be basic, but you need to comfortable with the back end of your website to implement them. I don't think these are for beginners.
