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!

Hreflang tags with link to redirect loop
Hi guys, I'm having a bit of an issue on a client site that I'm hoping someone can help me with. Basically, the client has two domains, one serving users in the Republic of Ireland (http://www.americanholidays.com), showing Euro prices, and the other serving users in Northern Ireland (http://www.americanholidays.com/gb_en/) showing £ prices. The issue I'm having is that the URL for the Northern Ireland page has a 302 on it and goes through another 2/3 301 redirects until it resolves as http://www.americanholidays.com, however it does then show the £ prices. You can see the redirect chain here: http://tools.seobook.com/server-header-checker/?page=single&url=http%3A%2F%2Fwww.americanholidays.com%2Fgb_en%2F&useragent=1&typeProtocol=11 The homepage is using the Hreflang tag, and pointing search engines to serve the http://www.americanholidays.com/gb_en/ page to users using EN-GB as their language. The page is also using a self-referencing canonical, which I believe may negate the whole Hreflang tag anyway? My main question is - is the fact that the Hreflang for the gb_en page is pointing to a chain of redirects negatively affecting it? (I understand too many redirects are never good). Also, is the canonical negating the Hreflang? Any help/info would be great as I just can't get my head around it! Thanks guys Daniel

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?

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!

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.

Is there a suggested limit to the amount of links on a sitemap?
Currently, I have an error on my moz dashboard indicating there are too many links on one of my pages. That page is the sitemap. It was my understanding all internal pages should be linked to the sitemap. Can any mozzers help clarify the best practice here? Thanks, Clayton

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 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
