Links from PubMed (nlm.nih.gov) not appearing in backlinks for articles
-
Content from our medical journals gets indexed by the National Library of Medicine / PubMed on a monthly basis. The link to the full article appears in the upper-right corner on PubMed, yet I'm unable to find PubMed (nlm.nih.gov) backlinks in the reporting tools.
Example:
Article Title: Respiratory Syncytial Virus Infection in Children (allintitle query)
Article URL: http://www.aafp.org/afp/2011/0115/p141.html
PubMed URL: http://www.ncbi.nlm.nih.gov/pubmed/21243988The PubMed link is to http://www.aafp.org/link_out?pmid=21243988 ,
a 301 redirect to the article, http://www.aafp.org/afp/2011/0115/p141.htmlAny idea why this link isn't appearing in backlinks? This isn't just for one article, we have roughly 2,000 articles from 1998 to the present. Articles from the past 12-months are access-restricted, and after 12-months the articles become public.

I feel very silly for posting this question.
Looking at the Pubmed source:
Doh!

The reason for this is most likely the use of a "out-link" with 301 redirect. Not 100% sure, but i would assume this is the reason for it not appearing in backlinks.

Internal Links issue in webmaster
we implemented our website on the basis of WordPress, then we migrate our website to PHP (YII Framework). after a while, we found out an issue around internal links which they were increasing severely. when we check our landing pages in webmaster (for example Price list), in contains 300 internal links but the reality is that there are no href tags on this page. it seems that webmaster calculate most of our links with the links of a single page and show them to us. is it natural or a mis configuration has been happened?

Should I no follow all external links?
I have worked with a few different SEO firms lately and a lot of them have recommended on the sites I was working on to "no-follow" all external links on the site. On one hand this traps all the link equity/Pagerank. On the other I would think this practice is frowned upon by Google. What are some opinions on this?

Ratio of linking C-blocks to Linking domains
Hi, Our linkbuilding efforts have resulted in acquiring a high number of backlinks from domains within a C-block. We all know Google issues penalties whenever someone's link profile looks unnatural. A high number of backlinks but a low number of linking C-blocks would seem to be one of reasons to get penalized. Example: we have 6,000 links from 200 linking root domains coming in from 100 C-blocks. At what point should we start to worry about being penalized/giving off an unnatural look to mr G?

Is having too many outgoing external links bad?
I'm currently writing articles for my site Eugene Computer Geeks and remember reading somewhere that having more then 100 outgoing links is a bad idea. I plan on writing lots of guides, and most of them will have several relevant links. Some examples are: a virus removal/prevention guide I want to link to the different antivirus programs I'm recommending. Or on the "Free WIFI in Eugene, OR" guide, I plan on linking to all the businesses' websites that offer free wifi. **Would having too many outgoing links hurt my rankings in anyway? ** If so, should I use the "nofollow" tag to prevent any harm? I always thought that having lots of relevant outgoing links was a good thing, but lately have been reading otherwise. What is all your opinions here at SeoMoz?

Too many on page links
Hello I have about 800 warnings with this. Example of one url with this problem is: http://www.theprinterdepo.com/clearance?dir=asc&order=price I was checking and I think all links are important. But I suppose that if I put a nofollow on the links on the left which are only for navigation purposes I can get rid of these warnings. Any other idea?

Internal linking to subdomains
Hi *, I have a main site called example.org, and a lot of user generated pages to foo.example.org / bar.example.org and so on. Most of those pages link back to example.org. In example.org I have a page that links to all subdomains. How can I optimize the pagerank of the list page? Should I add nofollow to subdomain sites to avoid passing link juice to those sites and keep normal linking from subdomain sites?
