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.

Backlink quality vs quantity: Should I keep spammy backlinks?
Regarding backlinks, I'm wondering which is more advantageous for domain authority and Google reputation: Option 1: More backlinks including a lot of spammy links Option 2: Fewer backlinks but only reliable, non-spam links I've researched this topic around the web a bit and understand that the answer is somewhere in the middle, but given my site's specific backlink volume, the answer might lean one way or the other. For context, my site has a spam score of 2%, and when I did a quick backlink audit, roughly 20% are ones I want to disavow. However, I don't want to eliminate so many backlinks that my DA goes down. As always, we are working to build quality backlinks, but I'm interested in whether eliminating 20% of backlinks will hurt my DA. Thank you!

Should we Nofollow Social Links?
I've been asked the question of whether if we should nofollow all of our social links, would this be a wise thing to do? I'm not exactly getting a clear answer from search results and thought you guys would be best to ask 🙂 Thanks in advance.

Referencing links in Articles and Blogs
Hi I am wondering if the <sup>tag in html is picked up by google as a reference point?</sup> I.e when you put a superscript in word it puts a small number next to your sentence. Then you have a list of reference at the end of the blog/article does google recognise this?

Links from Instructables.com?
This is a silly newbie question. But will posting on www.instructables.com with some valuable content and url link back to my site help with "linking"? Or do they put a no-follow on all links on their site? Thanks for answering! Ron

Dofollow and Nofollow links
What is the difference between dofollow and nofollow links? I know that some sites/blogs only let you post nofollow links. In such a case how do I know if a comment I posted on a certain site will be a nofollow or dofollow? How about big traffic sites such as Huff Post. Do they only allow nofollow links?

Does Yelp pass link juice?
This is probably a profoundly obvious question, but I can't seem to find an explicit answer on the internet, so I'll ask it here: Yelp's links out to local business websites are not nofollow'd, but they go through a javascript-based redirect. My understanding is that javascript redirected links do not pass link juice, so a link from a yelp profile will not directly impact my page authority; however, it looks like yelp does use nofollow judiciously for internal links, so I don't understand why they would allow follow for these "useless" outbound links. Do yelp's javascript-redirected links pass link juice?
