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?

Dofollow letting the bot crawl the target page

Thank you for the help Tom!

dofollow links pass "SEO Juice".
nofollow links do not pass "SEO Juice".
If your curious as to whether or not a particular blog allows for dofollow links, you can view the source code of the webpage using any common web browser. Find the link in question, and look to see if it includes "rel=nofollow". If that tag doesn't exist, then the link is dofollow.

Presuming that you're going to be linking to your website in the comment, I'd probably keep it limited to your own niche, but there's definitely room for a few comments from other industries.
If your comments are engaging, provide value to that blog's community and are not on blogs that are spammed to death, then you won't be doing any harm. The key is to comment something of worth and to integrate yourself into the community.
I always think of blog commenting as a way of establishing a community presence and to raise unaided brand awareness. Any subsequent link of page strength is an after-thought for me.

Thanks for the reply Tom, you were really helpful.
I had another question regarding the process of commenting on blogs/articles. Should I only comment on blogs/articles that are relative to my own niche or can I also comment and link from blogs/articles that are outside my niche?

Hi. Everything Tom said and I also wanted to add another extension to this - If you use Firefox this is for checking nofollow and dofollow links. When you add the extension, if you right click and select the nodofollow it hghlights nofollows in red and dofollows in blue. I use it all the time.

A dofollow link will pass the SEO strength, or "PageRank" of the page to the site that it links to. A nofollow link, in theory, will not do this. That's the main difference between the two.
By that logic, you may assume that a nofollow link will not help you rank for a keyword, but I don't think this is completely the case. Having a link to your site in any capacity may improve the "authoritativeness" of your site. SEOMoz uses Page Authority and Domain Authority to measure this and, while not an official Google metric, it stands to say that if you have 2 identical sites, one has 5 nofollow links from newspapers and the other has none, Google may well think that the site with the links has more authority or trust and may treat it more favourably. We all know how much Google loves to promote real brands.
As for seeing if a link is dofollow or nofollow, you can either inspect the element in the source code, or a convenient and hassle-free way to test is with the SEOMoz toolbar. That toolbar contains an option to highlight the links on the page - green links are dofollow and pink links are nofollow. If you check previous posts on any website, you should be able to see a pattern of whether they allow for dofollow or nofollow links - but in the end, this is at the discretion of the webmaster.
Hope this helps!

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! 🙂

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

Footer Links with same anchor text on all pages
We have different websites targeted at the different services our company provides. (e.g. For our document storage services, we have www.ukdocumentstorage.com. For document management, we have www.document-management-solutions.co.uk). If we take the storage site for example, every single page has a link in the footer to our document management site, with the anchor text 'Cleardata Document Management' SEOMoz is telling me that these are seen as external links (as they are on a different URL's), and I'm just clarifying that would this be a major possible factor in the website not ranking highly? How should I rectify this issue?

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.
