Noticed a lot of newbies lately, looks like IM is attracting more and more people, that is great, there is always room for an extra one ;-) That said, hope this list I collected of free tools for back-linking analysis helps ya out: Using blekko.com and typing in a url and including "/seo" at the end is a fast, free and an easy way to get link and other SEO related data. http://www.opensiteexplorer.org http://www.majesticseo.com http://www.backlinktest.com/ http://beta.openlinkgraph.net/ http://www.online-utility.org/webmaster/backlink_domain_analyzer.jsp http://journik.com/socialnetwork http://www.linkdiagnosis.com/ Google Webmaster Tools is pretty great for analyzing your own site as well, for those that have not set it up. http://www.seoheap.com/backlink-checker/.... I think it finds more links than other tools, give it a shot and compare... Also try Open Site Explorer, Back Link Watch and Web Link Validator... Also since the shut down of Yahoo explorer, I suggest http://ahrefs.com/ . it updates DB frequently and it meets many people's demand without buying it's service. Kinda Kewl.. Hope this helps. Enjoy !
