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?

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?

Fake Links indexing in google
Hello everyone, I have an interesting situation occurring here, and hoping maybe someone here has seen something of this nature or be able to offer some sort of advice. So, we recently installed a wordpress to a subdomain for our business and have been blogging through it. We added the google webmaster tools meta tag and I've noticed an increase in 404 links. I brought this up to or server admin, and he verified that there were a lot of ip's pinging our server looking for these links that don't exist. We've combed through our server files and nothing seems to be compromised. Today, we noticed that when you do site:ourdomain.com into google the subdomain with wordpress shows hundreds of these fake links, that when you visit them, return a 404 page. Just curious if anyone has seen anything like this, what it may be, how we can stop it, could it negatively impact us in anyway? Should we even worry about it? Here's the link to the google results. https://www.google.com/search?q=site%3Amshowells.com&oq=site%3A&aqs=chrome.0.69i59j69i57j69i58.1905j0j1&sourceid=chrome&es_sm=91&ie=UTF-8 (odd links show up on pages 2-3+)

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!

Should I nofollow search results pages
I have a customer site where you can search for products they sell url format is: domainname/search/keywords/ keywords being what the user has searched for. This means the number of pages can be limitless as the client has over 7500 products. or should I simply rel canonical the search page or simply no follow it?

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.

International Site Links In Footer
We have several international sites and we have them linked in the footer of our main .com site . Should we add "nofollow" to these links? Our concern is that Google could see these sites as a network?

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?
