I've done a ton of reading on Siloing, and I am getting ready to SEO a new site. I believe that Silo architecture is incredibly important. I see a lot of people claiming to be building silo architecture in WordPress, but every one of them has a persistent main navigation bar. If a site has a Nav bar, it can't really be siloed, can it? I am assuming, of course that the Nav is not being obfuscated by Flash, etc. Please tell me if I am wrong here. - If I am trying to silo a landing page , and all of the supporting pages have the navigation bar, then this is not a silo. You are bleeding link juice to all of the links in the nav. Am I wrong here? If I am, please explain why. is Siloing with a persistent nav bar effective? I am having a real hard time with this. In a true silo: 1. You need to strip out all navigation on the supporting pages except for: 2 . 1 link to the landing page 3. links to all of the other supporting pages. 4. Links from the landing page to all of the supporting pages Ex: Silo Landing page: widgets supporting pages: blue widgets red widgets steel widgets plastic widgets. "widgets" will link to all supporting pages supporting pages link to each other and "widgets" - 4 links each - no other navigation.
