Welcome to the Q&A Forum

I love these questions because they defy the laws of Google gravity!  There are many "indicators" outside of the commonly discussed you find most often in these forums.  You are on the right track in suspecting that Google takes the format of a site's content into consideration.  If a site has relevant textual content along with a variety of downloadable .doc or .pdf files with relevant titles, preference may be swayed toward the site that seems to offer the most relevant information.  Variety does matter, whether you're offering content that's supported by images, videos, outbound links, .doc documents, or .pdf documents, etc. I also suspect that .net extension carries more weight than .ro, but there's no conclusive evidence that I can find.

It's not april 1st so what's going on. <meta name="pagerank"  var="11" />

no, it's very important, i just thought that you had a tool to mesure link juice to a page (other than pr or authority). Thanks for the answer

Hey seo.academy, It sounds like your site hasn't been reindexed by Linkscape or like those other links are deeper than Linkscape is going on your site. Most new sites and links will be indexed by our spiders and available in Linkscape and Open Site Explorer within 60 days, but some take even longer for a plethora of reasons, including crawl-ability of sites, the amount of inbound links to them, and the depth of pages in subdirectories. Just so you know, here's how we do our index: we take the last index, take the 10 billion URLs with the highest mozrank (with a fixed limit on some of the larger domains), and start crawling from the top-down until we've crawled 40,000,000,000 pages (which is about 1/4 of the amount in Google's index). Therefore, if the site is not linked to by one of these seed URLs (or one of the URLs linked to by them in the next update) then it won't show up in our index We update our Linkscape Index every 3 to 5 weeks. Crawling the whole internet to look for links takes 2-3 weeks. And then we've got 1-2 weeks of processing to do on those links to determine which are the most important links etc. You can see a schedule of how often we update, and planned updates here: http://seomoz.zendesk.com/entries/345964-linkscape-update-schedule Linkscape focuses on a breadth-first approach, and thus we nearly always have content from the homepage of websites, externally linked-to pages and pages higher up in a site's information hierarchy. However, deep pages that are buried beneath many layers of navigation are sometimes missed and it may be several index updates before we catch all of these. If our crawlers or data sources are blocked from reaching those URLs, they may not be included in our index (though links that points to those pages will still be available). Finally, the URLs seen by Linkscape must be linked-to by other documents on the web or our index will not include them. I hope this information helps! It definitely sounds like for your issue specifically, it's a matter of those links not getting indexed yet. Also, I'd definitely recommend you use OSE instead of the Linkscape tool - OSE is much better. In the future, if you have a question about our site or tools, please email it to help@seomoz.org to get faster service. Thank you!

As mentioned, a "flat architecture" is measured by how many clicks away pages are from the home page. You could put everything in the main directory and still have pages that require 10 clicks to get to, or have files within 7 folders that are linked to from the homepage. That said, a logical hierarchy will make the most sense to you and your users.

I would not say they are more valued than any other kind of link but they do provide some distinct benefits and opportunities. when people land on the page from a web search, it provides a simple tool and a convention no less for anchoring yourself within the hierarchy of the site and navigating back a level depending on the source ordering it can often be the first link to the parent pages so can be used for keyword rich anchor text (where natural to do so) it can be some of the first text on the page so it provides a natural way to get your keywords (product name etc) at the beginning of the page which can also help Generally it is a good way to get your keywords on the page again without having to worry about working them into the body text in a natural way (which is not always possible) So, in summary, they are good for users, good for SEO (internal linking, keywords, relevancy) and they can help improve the format of your listing in the SERPs so... what's not to like? Hope it helps! Marcus
