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.

301 Redirect for multiple links
I just relaunched my website and changed a permalink structure for several pages where only a subdirectory name changed. What 301 Redirect code do I use to redirect the following? I have dozens of these where I need to change just the directory name from "urban-living" to "urban", and want it to catch the following all in one redirect command. Here is an example of the structure that needs to change. Old

Fake Links indexing in google
Hello everyone, I have an interesting situation occurring here, and hoping maybe someone here has seen something of this nature or be able to offer some sort of advice. So, we recently installed a wordpress to a subdomain for our business and have been blogging through it. We added the google webmaster tools meta tag and I've noticed an increase in 404 links. I brought this up to or server admin, and he verified that there were a lot of ip's pinging our server looking for these links that don't exist. We've combed through our server files and nothing seems to be compromised. Today, we noticed that when you do site:ourdomain.com into google the subdomain with wordpress shows hundreds of these fake links, that when you visit them, return a 404 page. Just curious if anyone has seen anything like this, what it may be, how we can stop it, could it negatively impact us in anyway? Should we even worry about it? Here's the link to the google results. https://www.google.com/search?q=site%3Amshowells.com&oq=site%3A&aqs=chrome.0.69i59j69i57j69i58.1905j0j1&sourceid=chrome&es_sm=91&ie=UTF-8 (odd links show up on pages 2-3+)

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

Link Volume - calculate what you need?
Hi everyone, an interesting question here. How do you determien what link volume you should try and get into your website? What analysis do you do to determine the number of links you feel is right to go into a back-link profiel every month? obviously there is no magic number but its an interesting question to know what others do. Obviously you don't want to build too many or too little. If you have been penalised for bad links in the past and are now back on track - how do you calculate the volume? Do you take links dropping out into consideration?

Do Backlinks to a PDF help with overall authority/link juice for the rest of the domain?
We are working on a website that has some high-quality industry articles available on their website. For each article, there is an abstract with a link to the PDF which is hosted on the domain. We have found in Analytics that a lot of sites link directly to the PDF and not the webpage that has the abstract of the article. Can we get any benefit from a direct PDF link? Or do we need to modify our strategy?
