Vertical Search is a new dimension in search engine industry that focuses on specialized areas for its search activity.
Google and Yahoo are broad based search engines that index everything available on the web. When you enter term “make money” the broad base search engine such as Google, it would list all the pages from every nook and corner.
Google does not know who is at the other end and what he would be interested in. It would assimilate all pages with relevant keywords and arrange them in order it thinks is most relevant for the search term.
But for the same term a stock broker would have an interest in different pages and an internet marketer would want different pages to be shown.
Both of them would be looking for different sets of pages for the exactly same keywords.
With technology pampering us and our life becoming more and more focused, we want everything the way we want. Surprisingly, the technology always comes with an answer.
If we have two search engines one of which deals in internet marketing and other in stocks, both the persons would strike relevant pages at one go.
This is the basic concept behind vertical search.
Broad-based search engines fetch very large numbers of documents using a crawler. Another program called an indexer then reads these documents and creates a search index based on words contained in each document. Each search engine uses its own algorithm to create its indexes so that, ideally, only meaningful results are returned for each query.
Vertical search engines, on the other hand, send their spiders out to a highly refined database, and their indexes contain information about a specific topic. As a result, they are of most value to people interested in a particular area.
Google Blogsearch, Google Local are examples of vertical search engines. Other examples are Technorati, Pluggd, Retrevo etc.
As user base becomes more focused, so would vertical search engine marketing.
Vertical search would be a common thing in times to come. It has already made an impact on people’s mind. There would be academic search engines, veterinary search engines, stocks search engines, marketing search engines and soon.
We are used to go to one place to look for everything. Vertical search is soon going to replace that.
