Paying More Attention To Page Segmentation For SEO Benefits  By
David Harry
Brother Bill expertly covered (yet another) patent on page segmentation the other day; this time from Yahoo. It is certainly an area that SEOs really might want to be paying more attention to these days. Considering that each of the big three have dabbled into it (to varying degrees) over the last ˝ decade, there is every reason to believe that something might be here (all that 'where there is smoke'... yada yada). Page segmentation has widely been developed for use in OCR applications to better understand text/image relationships. More recently, we've seen this area of expertise brought to the online world. One important aspect that should be of particular interest to those in the SEO world is in the link related ramifications. Let us consider that Google, the king of link reliant search engines, would certainly find a huge benefit from this approach for valuating links (or even indexation decisions). An interesting example is the recent update to the Google Blog search that fixed the issue of Google indexing blog roll links (problematic when using the link: command). As soon as that news broke I thought, 'How'd they do that I wonder?' - Obviously page segmentation came to mind. Benefits of page segmentation Now, as fastidious little detectives, the first thing we need to look for is motive. Why would a search engine want to do this? A few of the potential benefits include; • Crawling/indexing resources - once the template structure of a site is prioritized, infrequent crawling of, or discarding certain layers would save on computing and storage costs. • Topic Drifting - some pages will have more than one topic and search engines can struggle to properly index/categorize them.
• False positives - it can also better deal with problems that arise when a page contains links/citations to other topics not directly related to the content of the page. This approach would help improve the quality of the results in avoiding such false positives. • Spam Detection - obviously understanding boilerplate and other inherently spammy elements would be an important part of the value and attraction. • Paid links - it can also could go a long way in fighting link spam and paid links even. By devaluing segments or altogether passing them over, it makes the practice less enticing and handicaps the activity. These are but a few ways that page segmentation can be a useful tool for search engines. There are more, but I just wanted to get you up to speed (for more see last post on it). What we're concerned with this time is how it has the potential to change the world of links as we know it... m'kay? Continue reading this article.
