If a website is successful due to artificial link exchange, then the webmaster may not realize when it would be worthwhile to stop.

Thus within a local community it is fair to assume that the most cited resource is probably a solid authority for that industry. <br /> <br /> Teoma organizes its search results in this manner and Google has a patent for this technology titled "Ranking search results by reranking the results based on local inter-connectivity." <br /> <br /> Physical Example<br /> This concept can be applied to any topic, but is easily demonstrated if you think of physical location. For example, I live near an island called "Block Island." On the web there are lots of pages, but few pages are about that specific island. If we search Google for "Block Island" we will see that the top results are<br /> <br /> the Block Island home page <br /> the Block Island Ferry <br /> the Block Island newspaper <br /> Other sites may be able to sneak up and list well for the term, but due to grading local linking inter connectivity these results will remain at or near the top for a long time.<br /> <br /> If I were a small business owner on Block Island I may consider it a nice treat or added bonus to give my visitor a link to the Block Island Times home page. Each industry may fight amongst itself for top rankings, but many of the sites specific to things on Block Island will provide links to these sites without even thinking about it.<br /> <br /> How it Works<br /> When a user performs a search the search engine compiles a list of results in order of relevance. Then the search engine reviews the local link structure to see how the documents relate to one another.<br /> <br /> A resource which links to many other resources in a given field is considered a hub. A resource with many inbound links from these hubs and other related sites is then considered an accurate authority on the subject.<br /> <br /> See it in Action<br /> Teoma is the search engine which was purchased for $4,000,000 a few years back to power Ask Jeeves. While Ask Jeeves is consumer centric, the Teoma website does a better job of displaying the core technology which powers their search.<br /> <br /> Since Teoma is based on defining local authority it is not surprising to see the slogan "search with authority." The search results which appear on the left hand side of the page are the authority websites for the given search. <br /> <br /> The right column has two sections.
