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!

301 Redirect for multiple links
I just relaunched my website and changed a permalink structure for several pages where only a subdirectory name changed. What 301 Redirect code do I use to redirect the following? I have dozens of these where I need to change just the directory name from "urban-living" to "urban", and want it to catch the following all in one redirect command. Here is an example of the structure that needs to change. Old

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?

Should 301-ed links be removed from sitemap?
In an effort to do some housekeeping on our site we are wanting to change the URL format for a couple thousand links on our site. Those links will all been 301 redirected to corresponding links in the new URL format. For example, old URL format: /tag/flowers as well as search/flowerswill be 301-ed to, new URL format: /content/flowers**Question:**Since the old links also exist in our sitemap, should we add the new links to our sitemap in addition to the old links, or replace the old links with new ones in our sitemap? Just want to make sure we don’t lose the ranking we currently have for the old links.Any help would be appreciated. Thanks!

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.

Add to Cart Link
We have shopping cart links (<a href's,="" not="" input="" buttons)="" that="" link="" to="" a="" url="" along="" the="" lines="" of="" cart="" add="" 123&return="/product/123. </p"></a> <a href's,="" not="" input="" buttons)="" that="" link="" to="" a="" url="" along="" the="" lines="" of="" cart="" add="" 123&return="/product/123. </p">The SEOMoz site crawls are flagging these as a massive number of 302 redirects and I also wonder what sort of effect this is having on linkjuice flowing around the site. </a> <a href's,="" not="" input="" buttons)="" that="" link="" to="" a="" url="" along="" the="" lines="" of="" cart="" add="" 123&return="/product/123. </p">I can see several possible solutions: Make the links nofollow Make the links input buttons Block /cart/add with robots.txt Make the links 301 instead of 302 Make the links javascript (probably worst care) All of these would result in an identical outcome for the UX, but are very different solutions. What would you suggest?</a>
