It took me a really, really long time to accept that site speed is one of the most important factors when it comes to increasing traffic to your blog. Google likes it, Pinterest likes it, users like it. Any longer than 3-4 seconds for your blog to load and (supposedly) your traffic starts dropping off by double digit percentage points.
That means that for a lot of us, increasing site speed could increase our traffic by double digit percentage points.
The pot gets even sweeter from there because most ads run smoother when your site loads faster, so if you’re on an ad network, you could also start seeing higher RPMs.
