All these latest Google Search algorithm changes are making our visitor stats going wild both ways. The most important thing many webmasters forget to check after building a website is it’s loading speed. So many of them loading over 4 sec., even those with basic WordPress installation.
(try W3 Total Cache plugin).
I was dismissing Google algorithm changes at first, until I saw the stats for one of our websites; http://webimenik.biz to be exact. Website visits fell to over year and a half old averages. When I checked loading time it was obvious, WebImenik load time was over 5 sec. and first 3 was taken by CPU getting necessary data to show the front page.
