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.

		Size of image for article Schema
 Hi, I implemented schema markup for an article and all tested fine and I can see it being fired in preview mode of Google Tag Manager. But when I run the URL which has it applied through Google Structured Testing tool it is not appearing. I have now read that the image needs to be a certain size. For AMP articles this appears to be 12oo pixels wide http://www.thesempost.com/google-changes-image-size-requirements-amp-articles/ But what about non-AMP articles? Does it need to be that big too?

		Correct linking to the /index of a site and subfolders: what's the best practice? link to: domain.com/ or domain.com/index.html ?
 Dear all, starting with my .htaccess file: RewriteEngine On Technical SEO | | inlinear
 RewriteCond %{HTTP_HOST} ^www.inlinear.com$ [NC]
 RewriteRule ^(.*)$ http://inlinear.com/$1 [R=301,L] RewriteCond %{THE_REQUEST} ^./index.html
 RewriteRule ^(.)index.html$ http://inlinear.com/ [R=301,L] 1. I redirect all URL-requests with www. to the non www-version...
 2. all requests with "index.html" will be redirected to "domain.com/" My questions are: A) When linking from a page to my frontpage (home) the best practice is?: "http://domain.com/" the best and NOT: "http://domain.com/index.php" B) When linking to the index of a subfolder "http://domain.com/products/index.php" I should link also to: "http://domain.com/products/" and not put also the index.php..., right? C) When I define the canonical ULR, should I also define it just: "http://domain.com/products/" or in this case I should link to the definite file: "http://domain.com/products**/index.php**" Is A) B) the best practice? and C) ? Thanks for all replies! 🙂

		Blog article URL - with or without date?
 Quick question to all you folks: does including the date in a blog article's permalink affect rankings? For example, here's an article with the month and year, as well as the blog title: http://www.ayzanyc.com/blog/2012/12/difference-between-hot-chocolate-hot-cocoa/ Is it better to omit the date and just put the blog title? Also, if is better to avoid using the date, is it worth it to change the link structure of our previous articles (given that the URL will now be different), or should we just focus on future articles? Thanks ahead of time for your advice. Technical SEO | | onurkiyak0

		Odd backlinks from yahoo news
 Can anyone explain what this backlink does? The original content was syndicated on Yahoo News from Mashable. At first glance it appears to be a straight up follow link from Yahoo to Mashable, but upon closer inspection I saw this in the code. went public just three months ago Here's the article on yahoo news: http://news.yahoo.com/facebook-zynga-generates-12-revenue-them-175509319.html I've rarely seen backlinks from yahoo for any content partner let alone follow links. The us.lrd.yahoo.com in the hyperlink makes me highly suspicious. Technical SEO | | inc.com0

		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? Technical SEO | | pauledwards0
