Dangling Links

Dangling links

pagerank, page rank "Dangling links are simply links that point to any page with no outgoing links. They affect the model because it is not clear where their weight should be distributed, and there are a large number of them. Often these dangling links are simply pages that we have not downloaded yet..........Because dangling links do not affect the ranking of any other page directly, we simply remove them from the system until all the PageRanks are calculated. After all the PageRanks are calculated they can be added back in without affecting things significantly." - extract from the original PageRank paper by Google’s founders, Sergey Brin and Lawrence Page.

A dangling link is a link to a page that has no links going from it, or a link to a page that Google hasn't indexed. In both cases Google removes the links shortly after the start of the calculations and reinstates them shortly before the calculations are finished. In this way, their effect on the PageRank of other pages in minimal.

The results shown in Example 1 (right diag.) are wrong because page B has no links going from it, and so the link from page A to page B is dangling and would be removed from the calculations. The results of the calculations would show all three pages as having 0.15.

It may suit site functionality to link to pages that have no links going from them without losing any PageRank from the other pages but it would be waste of potential PageRank. Take a look at this example. The site's potential is 5 because it has 5 pages, but without page E linked in, the site only has 4.15.

Link page A to page E and click Calculate. Notice that the site's total has gone down very significantly. But, because the new link is dangling and would be removed from the calculations, we can ignore the new total and assume the previous 4.15 to be true. That's the effect of functionally useful, dangling links in the site. There's no overall PageRank loss.

However, some of the site's potential total is still being wasted, so link Page E back to Page A and click Calculate. Now we have the maximum PageRank that is possible with 5 pages. Nothing is being wasted.

Although it may be functionally good to link to pages within the site without those pages linking out again, it is bad for PageRank. It is pointless wasting PageRank unnecessarily, so always make sure that every page in the site links out to at least one other page in the site.

Next giant networking

Why Twitter is the next networking giant

I’m not sure that it will be to be honest. However, since I have seen a lot of bloggers make the move lately, I feel that Twitter could well become the next social media giant, especially in the Internet marketing niche.

Time will tell I guess. For the time being I will take every day as it comes. I’m not addicted yet with Twitter but am intrigued to see where this will lead anyway.

How about you? have you succumbed to the lure of Twitter yet?

Communitiy confusion

I am debating on all of these communities on which one of them is the best. I have joined all of these I have listed and many more. FriendFeed is great for keeping track of all of your entry feeds, pay per post is great if you can get someone to pay you to post, Blog reviews are nice because it helps your rating or PR, and Blogger Choice Award is also good for your rating, and PR. Like I said before these are just a few communities to help boost your blogs.

Companies that adopt blogs must realize that developing a candid dialog with customers is the best way to build a meaningful customer relationship.
Originality/value – This study is the first attempt to systematically investigate the corporate blogging phenomenon.

FriendFeed Picture


My site was nominated for Best Blog About Blogging!Mascot

The key or I should say the "point I am trying to get across" is that their are so many communities, and they become confusing on which one to join to help direct traffic or make money with your blogs. I am totally confused at this moment on what/ which one to join that would benefit my blogs.
