Teoma reckons Google does not produce highly entirely relevant sites, an argument pondered by professionals since Google arrived over three years ago.
Google finds sites via other search engines, which rate their popularity by analysing links between pages and determining which sites have received the most links from 'authority' sites, which in turn are measured by the links to them.
Teoma believes the method is flawed. their method looks for clusters of web pages focused on a particular topic. Then it analyzes the links to find which pages are most rated by members of specific interest groups, rather than recommendations by mass audiences.
Meanwhile Wisenut, Looksmart's search engine, reckons Google's method is open to manipulation. Wisenut claims to scrutinise page content more thoroughly to avoid this.
Altavista updates parts of its database four times a day to attract visitors.
But Google remains confident. It says the popularity of its search engine speaks for itself. Nobody can compete with its database, which carries 1.5 billion fully indexed documents, compared to Wisenut's 800 - 900 million, Altavista's 600 million and Teoma's 200 million.
Only time will tell....
