If you sell a product or service, tracking visits and visitors to your site has very little overall value as an independent metric. Where tracking visits does become valuable is in conjunction with other metrics.
Traffic metrics themselves can be easily manipulated. And many web marketers actually engage in practices that are designed to drive up visitor hits to the site without any consideration as to whether those visitors are the site’s target audience. For many, this is just old-fashioned SEO. Their job is to get rankings (and traffic), but it’s up to the business to convert that traffic into customers.
Unfortunately, this is an outdated SEO philosophy, and one that provides little value to the customer.
