ROI (return on investment) is a highly chased goal for most of web projects which have any way to convert their attendance to money. It is pretty simple to understand the main meaning of ROI: each action, development step of investment you make is compared with the funds it brings afterwards. If you invest less then you get in result, than your ROI is positive. Of course, you could not accomplish positive ROI always (unless you live in a perfect world) but the aspiration to the perfection is clear.
One of the most important aspects of ROI is the usage of any tool you have access to. That is why we are talking about footer as one of such aspects, although it is surely not the highest priority tool to consider. The reason is that there were lots of guides about headers, text content, visuals and other parts of any website but footer is usually ignored. We will try to show you the way this part of your WordPress website can also serve for the sake of ROI and overall user experience improvement.
