Tracking results for your online marketing is critical. This allows you to monitor both past and even real time data. The more up-to-date your data collection is the more likely you won’t waste money on online advertising. You will be able to see where the traffic is coming from allowing you to allocate your marketing dollars wisely.
Analytics for the web include both onsite and offsite analytics. Some examples of offsite analytics include syndication tracking and click-through rates for PPC advertising.
By knowing where you traffic comes from you can spend more time and money on that area while fine tuning test runs for less profitable traffic methods until they are fine tuned.
