Traffic rank is determined by analyzing browser reports for millions of Crawler Toolbar users. Obtained reports are sorted, tabulated, and analyzed to determine a given website’s traffic rank. This process renders the results reported in the Crawler Traffic Ranking screen.
Ex: example.com has a scope of 7% - meaning an average of 70,000 (per million) users visit this site.
- The Crawler Toolbar works only with the Internet Explorer browser. Sites frequented mainly by users of other browsers will be undercounted. For example, the AOL/Netscape browser is not supported, which means that we collects little data from AOL users, and our traffic to aol.com is likely lower than it would be for a more representative sample.
- The Crawler Toolbar works only on Windows operating systems. Although a large majority of the Internet population currently uses Windows, traffic to any sites which are disproportionately visited by users of other operating systems will be undercounted.
- In some cases traffic data may also be adversely affected by our "site" definitions. With tens of millions of hosts on the Internet, our automated procedures for determining which hosts are serving the "same" content may be incorrect and/or out-of-date. Similarly, the determinations of domains and home pages may not always be accurate. When these determinations change (as they do periodically), there may be sudden artificial changes in our traffic rankings for some sites as a consequence.
- The Crawler Toolbar turns itself off on secure pages (https:) for privacy/security reasons. Sites with more secure page views will be under-represented in our traffic stats.
