Thus the time for data collection would increase greatly. For similar reasons, previous studies have also traditionally set a limit on the length of domain names-for example, the Vaughan and Thelwall (2004) study set a limit of four letters. It is acknowledged that this sampling method excluded websites that have more than six letters in their domain names, introducing a bias favoring abbreviated domain names. However, this bias should not undermine the findings and conclusions from the study, as the focus of the study is to make a relative comparison of coverage of sites from different countries.

Sites with longer domain names from all countries were excluded.
