      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 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!

                        Should we Nofollow Social Links?

                        I've been asked the question of whether if we should nofollow all of our social links, would this be a wise thing to do? I'm not exactly getting a clear answer from search results and thought you guys would be best to ask 🙂 Thanks in advance.

                        Should we nofollow footer social links?

                        Like most sites today we have a whole raft of social links in our footer, these are on every page of the site and link out to Facebook, Twitter, YouTube, etc Should these links be nofollow to avoid juice leaving our site or would you recommend allowing them to be followed to increase the power of these social sites? Is there a definitive Yay or Na on these social links?

                        301 with nofollow ?

                        Hi, our ecommerce link penalty was revoked by google back in Feb 26th 2013, but to this day we have not seen any improvement on our rankings. Due to 80% revenue loss we had to layoff quite a few people to stay alive. Situation now is more dire then ever for our company. We have millions of dollars invested in our business and google just busted it for some "low quality" or "spammy links" as they call it. We want to try to move to a different domain and do a 301 from the old domain to make sure our previous customers can still find us as a last effort to stay alive. But doing so we do not want to the bad links juice to flow to our new domain. Can we do a 301 with nofollow and will that have any negative impact or any impact at all.? any suggestion is greatly appreciated. Thank you Nick We are planning on moving to a different domain after 10 years, and laying off bunch of people due to loss of revenue.

                        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.

                        Having www. and non www. links indexed

                        Hey guys, As the title states, the two versions of the website are indexed in Google. How should I proceed? Please also note that the links on the website are without the www. How should I proceed knowing that the client prefers to have the www. version indexed. Here are the steps that I have in mind right now: I set the preferred domain on GWMT as the one with www. I 301 redirect any non www. URL to the www. version. What are your thoughts? Should I 301 redirect the URL's? or is setting the preference on GWMT enough? Thanks.

                        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
