Link Harvester is a free link analysis tool that returns:
unique linking domains
their IP addresses & unique c block addresses of the links
links from .gov, .mil, .edu, or .ac.uk domains. Links from these domains
are likely rated better in authority type algorithms such as Hilltop
or TrustRank.
Link Harvester also bolds and autochecks domains that link from 5 or more
pages. You can then requery the Yahoo! database and spider deeper than the
1,000 link limit.
Link Harvester uses the Yahoo! API, provides CSV outputs, and is an open
source tool. If you are a heavy user or the query limit (5,000 daily requests)
is exceeded feel free to host your own copy of Link Harvester on your site.
Setup should take under a minute.
Link Harvester also links to the Internet Archives, WhoIs Source, and Google
cache near each link.
