The vocabulary premium-how the digital words rewards command over keywords

The other day, I was reviewing the statistics of this(and others) blog of mine, and it struck me that the most popular posts were the ones with jargon/keywords(thus increasing the traffic from Google and other search engines). The reason for this was perhaps that those posts showed up prominently in the results of certain keywords.

Other non trivial examples of this in practice are

• Journals insist on keywords for ease of indexing, but increasing with them going digital, these keywords are often most valuable to quickly locate the paper/article or to invite serendipity by browsing all content under a particular keyword. 
• Google Advertising has a successful 'Ad Words' program where advertisers bid for the right to exhibit their relevant content alongside the search results for certain keywords. 
• As the cybersquatting and legal domain name sale data shows, those who are creative enough to register popular domain names well in advance, can mint millions. 
• Blogs have a special term for keywords as 'tags','categories' etc so that the blog visitors can see similar content grouped together. 
• As veteran search engine users would have uncovered, an ounce of correct and comprehensive keywords can save a pound of laborious searching over hundreds of pages.  
• For patent landscape analysis or corporate name search, one needs creativity and a good vocabulary for finding out 'simillar' categories and names.
