One day last summer, Google’s search engine trundled quietly past a milestone. It added the one trillionth address to the list of Web pages it knows about. But as impossibly big as that number may seem, it represents only a fraction of the entire Web.
Beyond those trillion pages lies an even vaster Web of hidden data: financial information, shopping catalogs, flight schedules, medical research and all kinds of other material stored in databases that remain largely invisible to search engines.
The challenges that the major search engines face in penetrating this so-called Deep Web go a long way toward explaining why they still can’t provide satisfying answers to questions like “What’s the best fare from New York to London next Thursday?” The answers are readily available — if only the search engines knew how to find them.
Now a new breed of technologies is taking shape that will extend the reach of search engines into the Web’s hidden corners. When that happens, it will do more than just improve the quality of search results — it may ultimately reshape the way many companies do business online.
Anyone who has ever broached the subject of web design or search engine marketing is familiar with the term ‘keyword’. If you do any pay-per-click advertising then you should be spending a fair amount of time researching and tailoring your keywords to maximize your advertising budget.What I’ve found though, as time goes by, is that most people have truly only scratched the surface in terms of their knowledge of keywords and keyword phrases.
