Server-based versus tag-based analytic The advantages of server-based analytic are primarily in its integration and SEO solutions. This method uses the server logs that are already created by the company and so nothing new need be built; this also means that the company owns and retains the data at times, which is a key consideration all when buying data services from a supplier. Also, because the server-based method includes search engine spider data it can provide better S information than the tag-based solutions. This is because you have access to the real spider data itself rather than having limited data pulled into your tag-based software. Google Analytic, for example, is well known to have decreased its SEC analytic within its-based solution looking Tag-based analytic is by far the more preferable method when for rich user interaction data. This method enables logging of specific actions on elements within the page and gathering of advanced user data such as browser. Tag-based analytic also has the advantage of being able to count cached pages, which account for around one-third of all visits.
