Yahoo! Site Explorer counts the number of spiderable links (sites) linking to a website. The more InLinks a site has, the better. While all InLinks are given equal weight this does not mean that all InLinks are valuable or useful.

PageData counts the number of unique pages that Yahoo! is able to spider on a given website. This includes information on all subdomains of a URL.

It returns an approximate count that reflects duplicate documents and all documents from a host. deephits, therefore, is invariably equal to or larger than TotalHits. The deephits value is normally used as an information display on a search result page, reporting how many total documents matched the search terms.

The Data Analyzer delivers information for domain names which are not currently registered (in the zone file). It delivers a relative ranking number (1 to 10 with 10 being highest) for the number of DNS queries a domain name receives. The queries include all types of DNS traffic and can include automated bot traffic. Currently only .com domain names can be analyzed through Data Analyzer.

You can use up to 4 keywords in your search. Each keyword must be at least 3 characters in length. Using "begins with", "ends with", "contains any", and "exact match" will return all domains matching any of the keywords. Using "contains all" will only return domains that contain all of the keywords.
