people visit your site and five give you permission to send them information by giving you their email address, your opt-in rate is 5%.   Metric # 4 - Traffic stats   Traffic stats could consist of any number of metrics. However, knowing how many daily unique visitors came to your site is an important metric.   Metric # 5 - Source of visitors   Knowing where your traffic came from is also important, especially if they were driven to your site through a paid promotion. Your web stats package should be able to tell you which search engines your visitor originated from, in addition to, the URLs of the websites your visitors came from.   Metric # 6 - Average visitor time   Knowing how much time your visitor spent on a certain webpage (such as your home page) will let you know to what degree your visitor finds your site interesting. It can also tell you approximately where your visitors are jumping off. This metric is important to know for each webpage.   Metric # 7 - Most viewed web pages   Knowing which of your web pages are popular and which ones arent will tell you where your visitors interests lie, how well your visitor stays on their pathway to the closing page, and what webpages should be dropped (or tweaked).   With the metrics that I just mentioned youll be able to answer several key questions about your sites performance. But perhaps the most important is, "How much is each unique visitor worth to me?" This key metric will drive all your decisions about how much you can spend to profitability acquire new customers.   For example, if your visitor value is $1.00, you cant afford to pay $1.20 per click to drive new visitor to your site (unless youre strategically acquiring new customers at a loss).   Mistake # 14 - No Focus On A Niche.   In the offline world there is an old saying: "If everyone is your target market, no one is your customer." What this means that if you try to target a large segment youll appeal to nobody in particular.   General Niche Electronics Palm Pilots Women Pregnant Mothers Business Marketing for CPAs
