1、The webmasters tool allows you to check crawl issues, back links, outbound links and also sitemap.
2、When dealing with links, you either want the inbound or outbound links or both.
3、You can only really control your outbound links, so make sure they are good ones, however you determine the value of the links.
4、And as authorities, the outbound links they choose to make carry that much more value (you don't get to be an authority in your field by randomly linking out to irrelevant, junk sites).
