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!

Old URLs Appearing in SERPs
Thirteen months ago we removed a large number of non-corporate URLs from our web server. We created 301 redirects and in some cases, we simply removed the content as there was no place to redirect to. Unfortunately, all these pages still appear in Google's SERPs (not Bings) for both the 301'd pages and the pages we removed without redirecting. When you click on the pages in the SERPs that have been redirected - you do get redirected - so we have ruled out any problems with the 301s. We have already resubmitted our XML sitemap and when we run a crawl using Screaming Frog we do not see any of these old pages being linked to at our domain. We have a few different approaches we're considering to get Google to remove these pages from the SERPs and would welcome your input. Remove the 301 redirect entirely so that visits to those pages return a 404 (much easier) or a 410 (would require some setup/configuration via Wordpress). This of course means that anyone visiting those URLs won't be forwarded along, but Google may not drop those redirects from the SERPs otherwise. Request that Google temporarily block those pages (done via GWMT), which lasts for 90 days. Update robots.txt to block access to the redirecting directories. Thank you. Rosemary One year ago I removed a whole lot of junk that was on my web server but it is still appearing in the SERPs.

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

Self-referencing links
I personally think that self-referencing links are silly. It's blatantly easy for Google to tell and my instinct says that the link juice for this would simply evaporate rather than passing back to itself. Does anyone have information backing me up from an authoritative source? I can't find any info about this linked to Matt Cutts, Rand or any of those I look up to.

Drop Down Menu - Link Juice Depletion
Hi, We have a site with 7 top level sections all of which contain a large number of subsections which may then contain further sub sections. To try and ensure the best user experience we have a top navigation with the 7 top level sections and when hovered a selection of the key sub sections. Although I like this format for the user as it makes it easier for them to find the most important sections / sub sections it does lead to a lot of links within every page on the site. In general each top section has a drop down with approx 10 - 15 subsections. This has therefore lead to SeoMoz's tools issuing its too many internal links warning. Then alongside this I am left wondering if I shouldn’t have to many links to my subsections and whether I would be better off being more selective of when I link to them. For instance I could choose the top 5 sub sections and place a link to them from our homepage and by doing so I would be passing a greater amount of link juice down the line. So I guess my dilemma is between ensuring the user has as easy a time traversing the site as possible whilst I try to keep a close watch on where, and how, our link juice is distributed. One solution I am considering is whether no-follow links could be utilised within the drop down menus? This way I could then have the desired user navigation and I would be in greater control of what pages link to which sub sections. Would that even work? Any advice would be greatly appreciated, Regards, Guy

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?

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.

Does the Referral Traffic from a Link Influence the SEO Value of that Link?
If a link exists, and nobody clicks on it, could it still be valuable for SEO? Say I have 1000 links on 500 sites with Domain Authority ranging from 35 to 80. Let's pretend that 900 of those links generate referral traffic. Let's assume that the remaining 100 links are spread between 10 domains of the 500, but nobody ever clicks on them. Are they still valuable? Should an SEO seek to earn more links like those, even though they don't earn referral traffic? Does Google take referral data into account in evaluating links? 5343313-zelda-rogers-albums-zelda-pictures-duh-what-else-would-they-be-picture3672t-link-looks-so-lonely.jpg Sad%20little%20link.jpg
