I was looking at these guides at Yahoo Travel where they reference third party sites. Example: http://travel.yahoo.com/p-article-1...travelguide;_ylt=As2nahZZUuEhGINCoBPDzGfRFWoL One example is say "Amsterdam Travel Guide - VCarious - guides" The link to this third party site is: http://us.lrd.yahoo.com/_ylt=AiMQBu...s.com/Travel-Guide/Netherlands/Amsterdam.html My question is does this have any SEO value? Is there a way to tell if this backlink can be read by Search Engines? I've looked at Alexa's sites linking in tool but do not see it receiving a link from Yahoo Travel. Thanks,
Search engines can read such links. Backlinks are based on search engines. To be counted as a backlink, both page and linked page shall be indexed by a search engine like google, yahoo, alexa, etc.
