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.

Do Canonical Tags Pass Link Juice?
I have an ecommerce website where some pages link to a product page with a different URL. EXAMPLE: 1: /category/product1.html (not indexed by Google) with canonical pointing to product1.html Other page link to the product like below. 2: product1.html (indexed by Google) Now the question is, does 1: pass any link juice to product1.html or not? Is it worth to change everything and link only to one URL? My site is running on Magento!

How can I stop a tracking link from being indexed while still passing link equity?
I have a marketing campaign landing page and it uses a tracking URL to track clicks. The tracking links look something like this: http://this-is-the-origin-url.com/clkn/http/destination-url.com/ The problem is that Google is indexing these links as pages in the SERPs. Of course when they get indexed and then clicked, they show a 400 error because the /clkn/ link doesn't represent an actual page with content on it. The tracking link is set up to instantly 301 redirect to http://destination-url.com. Right now my dev team has blocked these links from crawlers by adding Disallow: /clkn/ in the robots.txt file, however, this blocks the flow of link equity to the destination page. How can I stop these links from being indexed without blocking the flow of link equity to the destination URL?

How does link juice flow through hreflang?
We want to use the hreflang tag on our site (direct users searching for the Spanish version of spanishdict.com to spanishdict.com/traductor). Before doing so, we were wondering how link juice flows through hreflang? Any insight or resources on this would be very helpful. Thanks!

Updating inbound links vs. 301 redirecting the page they link to
Hi everyone, I'm preparing myself for a website redesign and finding conflicting information about inbound links and 301 redirects. If I have a URL (we'll say website.com/website) that is linked to by outside sources, should I get those outside sources to update their links when I change the URL to website.com/webpage? Or is it just as effective from a link juice perspective to simply 301 redirect the old page to the new page? Are there any other implications to this choice that I may want to consider? Thanks!

How to find all crawlable links on a particular page?
Hi! This might sound like a newbie question, but I'm trying to find all crawlable links (that google bot sees), on a particular page of my website. I'm trying to use screaming frog, but that gives me all the links on that particular page, AND all subsequent pages in the given sub-directory. What I want is ONLY the crawlable links pointing away from a particular page. What is the best way to go about this? Thanks in advance.

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?

Forum Profile Links
Are they really important? Many preach they are, and there are tonnes of services out there who give you thousands of forum profile links in no time. I strictly believe in genuine links built the hard way, and definitely don't want to get into anything which is black hat. Please suggest if building several Forum Profile Links is an appropriate way of building links?

Is link cloaking bad?
I have a couple of affiliate gaming sites and have been cloaking the links, the reason I do this is to stop have so many external links on my sites. In the robot.txt I tell the bots not to index my cloaked links. Is this bad, or doesnt it really matter? Thanks for your help.
