When they come to your website, your visitors give you three seconds. 40% of visitors will abandon your website if it takes too long to load.

Worse, a one-second delay in page response might result in a 7% decrease in conversions. You'll lose 40% of your website traffic, with 80% of those visitors never returning.

I could go on and on about these alarming loading time data, but the simple fact is that if you want to increase traffic and conversions, your website must be fast. You'll lose hundreds of thousands of dollars every year if you don't work on improving loading speeds.

Fortunately, there is a workaround: use a WordPress cache plugin.
