The Importance of Relevant CONTENT Links
TheGypsy recently penned a good write-up on phrase based optimization (Part I, Part II). I wanted to write a prequel of sorts on why building relevant content links are important.Page Segmentation…I know it’s a dead duck, but it seems everyone has different ideas on what this actually is. I’m not an IR expert, but here is my view on the subject. Page segmentation attempts to extract the sections of a web page. This is not based on anything visual as some people often proclaim. It will extract blocks from the document in order to find the more important sections of a page. Repetitive information such as navigation and advertisements can be easily pulled out and given a lower weight, as these components are often placed in certain positions and formats on the site in question and throughout the structure of the web, as well as often use the same text throughout. This is done using a ‘shingling’ algorithm to determine duplicate content and to filter out those noisy links.
Based on this interpretation, different blocks may contain links to different topics. Traditional link analysis did not differentiate links out of different semantic blocks. There is a fair amount of math involved which I will skip over, but the just of it is that sections with semantically relevant content that have passed the shingling filters are more important than those that are in navigational (margin) areas. It should also be noted the user will probably be viewing the larger content related blocks with a higher frequency and be more inclined to follow those links. There are additional formulas for determining relationships between blocks on a page, as it is likely some blocks in the navigational area are related. This is why the weight of these can fluctuate.
Another theory is to use an authority score on both the entire page and on each individual block together. This is calculated by first pulling the most important pages, then looking at the most important blocks on those pages. Theoretically this will allow the search engine to filter out the noise of advertisement and navigation type links. You can see that links in advertisements are normally in less important blocks, and could be assigned a lower weight (or none at all) than those in main content areas.
Lesson here? Get your links inside relevant content. Forget sidebar and ROS links when you can. Then go and read about phrase based indexing so you actually use the correct linking model. Then go buy some content links and have a heyday.

WOW! That’s some great stuff. First off, I doubt FEW PEOPLE get our techno-babble ( IMO of course). That’s why Part I NEEDED Part II. Outside of that Pge Segmentation is a GREAT area of study I have gotten into a bit. Email me – once again I think we could work together on ‘stuff’
Thanks again for the ‘Love’ …. Jus lookin for reality

Hey Dave! Thanks for the shout out, and I agree about the techno-babble…I try to keep it as simple as possible but sometimes it’s tough. And for workin on somethin, I’m in. I’ll shoot you over something soon and we can come up with some ideas.

i agree this, Always content page link only increase our page quality, resources page link doesn’t improve our page ranks, content page link only useful and get our site in top place in search engine using good and quality keywords
