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!

Should internal links in my table of contents be tagged as nofollow?
Hi All, I have the LuckyWP Table of Contents plugin installed. I recently noticed that you can tag your internal links with and nofollow. I understand that it's always a good idea to link internally and to pass link juice to my own content. But with detailed posts that have over 20 headings, I'm thinking that internal linking for headings may actually hurt me because it takes my links well above 100. Any ideas what the best practises are in this scenario? Thanks.

Referencing links in Articles and Blogs
Hi I am wondering if the <sup>tag in html is picked up by google as a reference point?</sup> I.e when you put a superscript in word it puts a small number next to your sentence. Then you have a list of reference at the end of the blog/article does google recognise this?

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+)

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.

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

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?

Does Yelp pass link juice?
This is probably a profoundly obvious question, but I can't seem to find an explicit answer on the internet, so I'll ask it here: Yelp's links out to local business websites are not nofollow'd, but they go through a javascript-based redirect. My understanding is that javascript redirected links do not pass link juice, so a link from a yelp profile will not directly impact my page authority; however, it looks like yelp does use nofollow judiciously for internal links, so I don't understand why they would allow follow for these "useless" outbound links. Do yelp's javascript-redirected links pass link juice?

Is link cloaking bad?
I have a couple of affiliate gaming sites and have been cloaking the links, the reason I do this is to stop have so many external links on my sites. In the robot.txt I tell the bots not to index my cloaked links. Is this bad, or doesnt it really matter? Thanks for your help.
