In a different post i wrote about how adding keyword targeted articles of about 200 words on your website would be appealing for the searchengines.

But the fact might be that you at this time are not at the point in time where this might benefit you.

Depending upon where your market is, and what products you are offering you might not want to add these extra articles untill you have reached a pagerank of 3-5.

In the beginning you are better off writing articles or posts on your website that have significant value for users, these long articles are more likely to be linked to from other websites.

I think Wikipedia is a great example of a website with a wealth of information, and it is being linked to because of that reason.

People are linking to Wikipedia articles and bookmarking them because they found just what they need there.

And the bookmarking and linking will usually be done for their own future reference, and sometimes the reason might be that the article had just too much information to chew in one go, so they will have a look at it another time.

I am not saying any of us going to compete with Wikipedia, but it goes to show that useful information for users will go a long way for building Pagerank.

Your users will be less inclined to link to your short fluffy articles that do not really carry any real meat.

But those short articles will still gain some juice from your internal site linking, but only if you built Pagerank and relevant links in the first place from outside websites.

To be within Google guidelines you should up your short article/long article balance in a way that improves the userexperience of browsing your site.

The way i am doing this right here now is that this article will be an update to:
Seo main article

I will then add a link here to that article like i done above, and also update the main article with the most relevant parts of this article.
