JavaScript unmasks key,<br \/>\ndistinguishing information about the visitor (the pages they are looking<br \/>\nat, the browser they use, etc.), while cookies are responsible for<br \/>\nstoring all of this information and determining visitor uniqueness. When<br \/>\nusers turn off JavaScript or cookies, it reduces the quality of the<br \/>\ninformation.<\/p>\n<p><strong>Dependence on Cookies as a Unique Identifier:<\/strong> While<br \/>\nclient-side solutions profess to provide human visitor information, they<br \/>\nactually provide information about web browsers. The following<br \/>\nassumptions made in client-side data collection raise the probability of<br \/>\nerror:  <\/p>\n<\/p>\n<ul>\n<li>A single user equals a single browser<\/li>\n<li>A web browser will not have multiple users<\/li>\n<li>Cookies are not likely to be turned off<\/li>\n<li>People allow their browser&#8217;s cookie cache to accumulate<\/li>\n<li>People are loyal to a single browser<\/li>\n<li>People are reluctant to spend money on a new computer<\/li>\n<\/ul>\n<p><strong>Adding Page Tags to Every Page:<\/strong> Without a built-in<br \/>\nheader\/footer structure for your website, this step will be very time<br \/>\nintensive. Those who already have this structure set up can simply<br \/>\ninsert the page tag in a common header and footer file. For static sites<br \/>\n(that don&#8217;t use server-side includes), this tag will have to be<br \/>\nmanually inserted on every page to be tracked.<\/p>\n<p><strong>Tag Implementation Complexity:<\/strong> The complexity of<br \/>\nyour page tags and vendor selection will determine how long the project<br \/>\ntakes. Tagging can be done in a matter of hours or it can take weeks or<br \/>\nmonths.<\/p>\n<p><strong>Page Performance:<\/strong> Visitors may experience a change<br \/>\nin the download time of your site, as the JavaScript code needed to<br \/>\ntrack your pages is never zero-weight.  Vendors that tout otherwise are<br \/>\nincorrect.<\/p>\n<p><strong>Time Limits on Data Storage:<\/strong>  Many page tag vendors cannot store collected data indefinitely due to disk space and rising storage costs.<\/p>\n<p><strong>Limits on Type of Data Collected:<\/strong> Page tags have<br \/>\nsome restrictions in their ability to report on non-HTML views such as<br \/>\nAdobe PDF files, error pages, redirects, zipped files and multimedia<br \/>\nfiles.<\/p>\n<p><strong>Privacy Concerns:<\/strong> Privacy is a hot topic for<br \/>\nconsumers and legislators. Issues abound concerning the types of data<br \/>\ncollected, how they are used and where they are stored. Because of this,<br \/>\nmost client-side web analytics vendors issue a privacy policy notifying<br \/>\nusers of data collection procedures. It is a good idea for their<br \/>\nclients to post a privacy policy covering the client-side data<br \/>\ncollection as well. <\/p>\n<p>A final drawback of the client-side applications is their inability<br \/>\nto capture data from users who do not have JavaScript enabled (i.e.<br \/>\ncookies). <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dependence on JavaScript and Cookies: Page tags are reliant on JavaScript and cookies.
