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.

Broken canonical link errors
Hello, Several tools I'm using are returning errors due to "broken canonical links". However, I'm not too sure why is that. Eg.

Page URL: domain.com/page.html?xxxx
Canonical link URL: domain.com/page.html
Returns an error. Any idea why? Am I doing it wrong? Thanks,

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?

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?

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

Add to Cart Link
We have shopping cart links (<a href's,="" not="" input="" buttons)="" that="" link="" to="" a="" url="" along="" the="" lines="" of="" cart="" add="" 123&return="/product/123. </p"></a> <a href's,="" not="" input="" buttons)="" that="" link="" to="" a="" url="" along="" the="" lines="" of="" cart="" add="" 123&return="/product/123. </p">The SEOMoz site crawls are flagging these as a massive number of 302 redirects and I also wonder what sort of effect this is having on linkjuice flowing around the site. </a> <a href's,="" not="" input="" buttons)="" that="" link="" to="" a="" url="" along="" the="" lines="" of="" cart="" add="" 123&return="/product/123. </p">I can see several possible solutions: Make the links nofollow Make the links input buttons Block /cart/add with robots.txt Make the links 301 instead of 302 Make the links javascript (probably worst care) All of these would result in an identical outcome for the UX, but are very different solutions. What would you suggest?</a>

How to find links to 404 pages?
I know that I used to be able to do this, but I can't seem to remember. One of the sites I am working on has had a lot of pages moving around lately. I am sure some links got lost in the fray that I would like to recover, what is the easiest way to see links going to a domain that are pointing to 404 pages?
