Abstract: 
The primary webometric method for estimating the online impact of an 
organization is to count links to its website. Link counts have been available 
from commercial search engines for over a decade but this was set to end by 
early 2012 and so a replacement is needed. This article compares link counts 
to two alternative methods: URL citations and organization title mentions. 
New variations of these methods are also introduced. The three methods are 
compared against each other using Yahoo!. Two of the three methods (URL 
citations and organization title mentions) are also compared against each 
other using Bing. Evidence from a case study of 131 UK universities and 49 
US Library and Information Science (LIS) departments suggests that Bing's 
Hit Count Estimates (HCEs) for popular title searches are not useful for 
webometric research but that Yahoo!'s HCEs for all three types of search and 
Bing's URL citation HCEs seem to be consistent. For exact URL counts the 
results of all three methods in Yahoo! and both methods in Bing are also 
consistent. Four types of accuracy factors are also introduced and defined: 
search engine coverage, search engine retrieval variation, search engine 
retrieval anomalies, and query polysemy.
