It’s a clear answer but Honnestly …

I m a little bit surprised about using nofollow link in 2011 (in a page rank perspectve)

In one part, We “heared” that using nofollow create an evaporation of page rank, in an ather part, I m sure that you have a strong knowledge to share, and if you recommand (in some case) the used of nofollow, i m sure that you know what you’re saying, so :

Do you recommand to use nofollow (between differents silos supporting page) for control the flow of “page rank” ?

or,

Do you recommand to use nofollow for control the “flow of relevance flow”/”flow of trust” within the pages (accepting to loose few points of page rank) ?

According to Bruce Clay guidelines we recommend that you link between supporting pages within a silo. Since the /ice-cream/black-strawberry.html page and the /ice-cream/strawberry.html both lie in the Ice Cream silo, and both are pointing to the Ice Cream landing page it is perfectly fine to add a link on the /black-strawberry.html page pointing at the /strawberry.html page.

It is treated differently however if you link from a supporting page in Silo A to a supporting page in Silo B (linking supporting pages within different silos). In this case, you can link to each other but remember to include the rel=nofollow attribute as the destination URL is not a landing page and you don’t want to cause PageRank bleed from the Ice Cream silo.

Ideally, you should move your /ice-cream/black-strawberry.html page to /ice-cream/strawberry/black.html to create a stronger silo around strawberry.

Hope that answers your question!

let me give you an example of situation that for me is problematic.

Lets say that i have a landing page about “ice cream”

url : /ice-cream/index.html for –> “ice cream”

And these subsection pages :

url : /ice-cream/strawberry.html for “strawberry ice cream”

url : /ice-cream/chocolate.html for “chocolate ice cream”

url : /ice-cream/black-strawberry.html for “black strawberry ice cream”

I know that this example is funny, but could i add a link on black-strawberry.html that point to strawberry.html (of course using it’s specific anchor text) and vice versa.

Thanks for your help

I hope you’ll help me to undersand one point concerning Siloing in 2011.

Historical rules of siloing says : To don’t link between subsection contents (also if they are part of the same directory ?)

Let say that i have a landing page that i m trying to rank for a single Keyword. Then i have athers pages (subsection contents) that :

> 1st, Are supposed to support my favorite landing page
> 2nd, I m trying to rank each for a more specific “keyphrase”

Let’s focus on these specifics pages now. Knowing that they have a verry strong “relation” between them (and not only with the landing page), why i couldn’t also link between them ? (of course using specific mid tail anchor text for each one of them ?)

If it’s really relevent in the context, why i couldn’t do it ?

Is it possible to try to think about a new and a little bit more “flexible siloing approach” that authorized (only if it’s really relevant) linking between these subsection pages ?

Thank you so much.

PS: If not, don’t you see a risk that these pages will be not often crawled by robots ?
