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!

Is link equity passed through redirect chains?
Hi there, When redirects are passed through multiple stages e.g. https://www.google.com 301 to http://www.bing.com 301 to http://www.yahoo.com Does http://www.yahoo.com still retain all link equity from the original referring domain, and is there a limit to the redirect chain before Google starts to not pass through link equity? Cheers

1 - Call To Action - Static to a landing page
10 Calculators - Static - These calculators I think are very useful to our users (financial website). So in total 17 total sidebar links, 11 static links, and 6 which change based on the content of the page. Do you think these static links from an SEO perspective can be hurting us? Is there some sort of best practice for sidebar links in regards to quantity as well as static vs non-static? Thanks!0 -
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?

Why are these internal pages not showing any internal links?
If you look at Author profile pages like this one, http://experts.allbusiness.com/author/denise-oberry (THE top contributor on the site with over 82 posts under her belt), or any Author profile page, they show zero internal links or Page Authority. The same goes for most posts for each author on the site. Author pages should show internal links from every post the author has on the site. And specific posts should also have internal links from categories, etc. Yet they show zero. The only posts that show internal links and PA are ones that were either syndicated to the root domain's homepage, or syndicated to Fox Small Business. ZERO internal links. Does anyone know why this is? The root domain does not act this way with Author pages and posts. And I see nothing blocking links or indexing via the robots.txt file or page level nofollow tags. A real head scratcher for this SEO nerd, that I'm sure someone here will have a really simple answer to.

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.

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?
