I would like to take a moment to present a very powerful link building technique that has been long overlooked by webmasters. It’s actually quite a shame. Every SEM I’ve ever met has managed to just skip right over the subject of Document Links without a second look.
Search engine engineers are very adamant in talking about their engines indexing power in regards to the term “documents.” MSN, Yahoo, and Google all worked very hard so their engines can index and understand other forms of documents than just HTML pages. They also worked very hard so they can analyze the links within those documents and extract them for credit as well. If I was in the same boat I’d demand the people writing the FAQs and guidelines to use the proper term(document) as well. After all it’s the least they could do. So why not take it literally?
