Some traffic is worth having and some website traffic is just a waste of broadband. For example, a client who was receiving a large amount of traffic for having an image called 'spanner' which was ranked highly under Google images.
Although flattering that so many users over the world would prefer our spanner image, the traffic was useless from a commercial point of view
"traffic is for vanity, web sales
are for sanity"
At the end of the day traffic equals enquiries, and enquiries leads to sales and return on your website promotion investment (ROI).
