Run a speed test on your website.
If your website is slow, people will not read it. Worse, Google will not index it. So get out there and run a speed test!
There are two things modern web surfers will wait for, their online bank statement and their online credit card statement. If you’re not a bank, stop making people wait for things.
Anecdotally I can prove this to you. When I worked as the head geek for a university we had a device that could throttle (limit) the speed of the Internet by the website. That means that I could choose to retard the speed of a website and that’s exactly what we did to a major social media site.
Instead of blocking from our users, we simply made it unbearably slow. Instead of reading status updates, staff returned to work.
