I've been working on the page load speed on the Tri-County Web site.
My goal is to apply the techniques I have implemented here to the other site I manage. Google and Bing use page speed in factoring in page rankings. So the fast a site loads theoretically it should rank higher.
It has not been confirmed or denied by any entity that fast loading sites help with ranking. It does help with visitors, especially on mobile devices.
There is a new Google update planned in the not distant future which will take into consideration page speed so lets err on the side of caution and go for a fast loading website.
As you can see from the image below I have pretty much accomplished my goal.
NOTE: The site layout has changed since this article was written but the results are the same.
