Too many businesses believe that the people who come to their website are unpredictable. That they’re out of control, entirely irrational and impossible to control.
This is nonsense.
The people who come to your website can only read the content that you present to them.
They can only click the links and buttons that you put in front of them.
If you don’t want so many of your visitors to go from the main page to the contact page, then remove it from the top navigation.
If you want more people to click on your main products page, then get rid of some of the other links and distractions. And make the link text more compelling. You can do better than Products can’t you?
You’re in control of what your visitors do when they arrive. Control your traffic.
