Many websites do not publish their traffic figures, so it can often be difficult to get accurate values. However, some commercial websites offer media data as PDF files or else on an extra advertising page: there you will find all relevant traffic figures and even demographic data on visitor groups. Because information about traffic and target groups is extremely important for companies that want to advertise on websites, website operators only publish their figures out of self-interest to woo potential advertising partners.
Websites produce traffic rankings and statistics based on those people who access the sites while using their toolbars and other means of online measurements. The difficulty with this is that it does not look at the complete traffic picture for a site. Large sites usually hire the services of companies such as the Nielsen NetRatings or Quantcast, but their reports are available only by subscription.
Once you have your list, choose an email marketing service provider that can provide design templates, send the emails for you and help you comply with CAN-SPAM and privacy regulations. Track the results of your email campaigns using analytics tools from your email marketing service provider, and update your email database regularly to ensure the addresses are still current.
I find it interesting that you talked about nutrition supplements for athletes. I am very close to launching such a product for enhancing aerobic exercise performance in women (ie. improved times in a 3 mile run).. The product contains no stimulants or exotic herbs. In fact three of the five ingredients are well known minerals, but in forms not found in most multi-vitamin-mineral supplements. The research behind the product comes from me. The credibility behind the research is that I am a professor of human nutrition with over 100 research papers. Now, the trick will be to use my connections and credibility in a business savvy way.
The majority of website traffic is driven by the search engines. Millions of people use search engines every day to research various topics, buy products, and go about their daily surfing activities. Search engines use keywords to help users find relevant information, and each of the major search engines has developed a unique algorithm to determine where websites are placed within the search results. When a user clicks on one of the listings in the search results, they are directed to the corresponding website and data is transferred from the website's server, thus counting the visitors towards the overall flow of traffic to that website.
