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!

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!

Advice on Linking to an Adult Related Website
I have a question regarding whether or not Google would penalize my main website for linking to a website that has adult content. The site I am linking to is not a porn site, rather it is a site that sells web site templates for adult related stores selling sexy toys, videos, etc. For example my site that is linking to the adult related website is here: http://www.websitetemplatedesign.com/ and the link to the site is in the footer at the bottom left which is an icon. And it links to http://www.adultsextemplates.com/ Im just looking for advice as to whether or not this could be a penalty or not. I did suffer major SERP loss in the last month and Im trying to find what I am doing that may have caused this. Any advice would be appreciated.

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?

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?
