Figures on a free website traffic checker are never completely accurate – tests have shown there may be considerable deviations. Therefore, you should always consider the results as estimates and guidelines. The tools are more suitable for a quick traffic comparison of different websites than for determining precise key figures. Important: to ensure that the comparison is also meaningful, it is best to always use the same tool – otherwise the results can be heavily falsified.
Web analytics is the measurement of the behavior of visitors to a website. In a commercial context, it especially refers to the measurement of which aspects of the website work towards the business objectives of Internet marketing initiatives; for example, which landing pages encourage people to make a purchase. Notable vendors of web analytics software and services include Google Analytics, IBM Digital Analytics (formerly Coremetrics) and Adobe Omniture.
