Single access pages
Which pages are being viewed by themselves, where visitors aren’t even clicking to go to another page? Again, look at these pages carefully to see what you can provide on the page to keep up the interest of your visitors. You’re losing them, and you need to figure out why.
If 70-80% of your visitors only looked at one page, perhaps you need to look at your navigation system. Are visitors confused and unable to find what they’re looking for?
