Although Latent Semantic Indexing is believed to impact only the content of a website, there is no denying that LSI has also impacted the way search engine optimizers carry out link building. To better understand the way LSI has impacted link building, it is important to understand LSI. LSI is a patented technique employed by Google to index and cache pages based on their keyword density. Before LSI, Google focussed on the web elements while it was indexing and caching pages, however LSI has changed the way Google generates search results.



Every time a Google bot visits a webpage, it uses the LSI algorithm to carry out a keyword density on the web page it is visiting. Once Google has used LSI to calculate the density of various keywords on the webpage, it then indexes the web page for the keywords. Whenever a user runs an organic search for a particular keyword, Google looks up web pages that have been indexed using LSI and displays web pages with the relevant keyword density for the search result. Although the LSI algorithm might not look like it can influence incoming links to a webpage, there is one very important aspect overlooked by webmasters.

Every time a Google bot visits a web page, it indexes more than just the content on the page. Google bots index pretty much everything that is textual on the webpage, this means that the text on every single link is also cached and indexed by Google. For example, if an outgoing link has the content ?click here for used cars?, Google will index this content also and the outgoing link will be associated with the keyword used cars.

Anyone who has logged in to Google Webmaster Tools will have noticed that Google has a section dedicated to what other websites see about the site. In a nut shell, an incoming link is only meaningful if it is embedded within relevant keywords. LSI has forced search engine optimizers to rethink the way they carry out link building. Instead of simply paying for advertisements and banner ads, it is makes much more sense to pay a website to sport a text rich out going link to a website. In fact, webmasters have started preferring text links because Google pays special emphasis on the content of the outgoing links of a website.

If you are looking to carry out link building it is important that you pay special attention to the content of the webpage on which your link is being displayed. In addition, make sure that the content of the link is also keyword rich and has the keywords you are targeting. What is equally important is making sure that the content of the web page that has an outgoing link to your websites is also keyword rich. Another factor to keep in mind is that the actual content of each link should vary to avoid repetition of content.
