Does using data-href="" work more effectively than href="" rel="nofollow"?
-
I've been looking at some bigger enterprise sites and noticed some of them used HTML like this:
<a <="" span="">data-href="http://www.otherodmain.com/" class="nofollow" rel="nofollow" target="_blank"></a>
<a <="" span="">Instead of a regular href=""
Does using data-href and some javascript help with shaping internal links, rather than just using a strict nofollow?</a>
-
I think this is actually a really good question. The main reason most SEOs these days don't "sculpt" or "shape" with nofollow links anymore has to do with the fact that they will still take away from the total amount of pagerank available to be passed on to other links on the page. So the question I'm reading above seems to be:
Do<a data-href...="" links="" still="" take="" a="" portion="" of="" pagerank="" away="" from="" the="" total="" pr="" available="" to="" be="" passed="" on="" other="" same="" page?<="" p=""></a>
<a data-href...="" links="" still="" take="" a="" portion="" of="" pagerank="" away="" from="" the="" total="" pr="" available="" to="" be="" passed="" on="" other="" same="" page?<="" p="">My answer is "I don't know" but I'd like to see a test if anyone can think of a way to try it out.</a>
<a data-href...="" links="" still="" take="" a="" portion="" of="" pagerank="" away="" from="" the="" total="" pr="" available="" to="" be="" passed="" on="" other="" same="" page?<="" p="">However, even if the test came back saying "No, these are treated differently and do not currently affect the total amount of PR available to other links on the page" I still would not use it for the purpose of pagerank sculpting. The reason is that how Google treats these links today can change tomorrow, making "tactics" like this a bad idea IMHO. It just leaves a mess for either you or some other poor SEO to cleanup later.
If I don't want pagerank to pass through a link on a page I simply don't put the link on the page. In extreme circumstances where there is no other way around it I might consider obfuscating the link with some javascript, for instance. However, even if you block the .js file that handles this "link" in the robots.txt file Google still executes it (as you can see when viewing the cached version on Google for pages that do this).</a>

Hi Jonathan,
I highly doubt it, you normally use the data-href to trigger some events with JavaScript and as these links still have the rel="nofollow" it probably will have the same value (0, as it's nofollow) to search engines.

In writing the url, it is better to use the language used by the people of my country or English?
We speak Persian and all people search in Persian on Google. But I read in some sources that the url should be in English. Please tell me which language to use for url writing?

Quick Fix to "Duplicate page without canonical tag"?
When we pull up Google Search Console, in the Index Coverage section, under the category of Excluded, there is a sub-category called ‘Duplicate page without canonical tag’. The majority of the 665 pages in that section are from a test environment. If we were to include in the robots.txt file, a wildcard to cover every URL that started with the particular root URL ("www.domain.com/host/"), could we eliminate the majority of these errors? That solution is not one of the 5 or 6 recommended solutions that the Google Search Console Help section text suggests. It seems like a simple effective solution. Are we missing something?

Does my "spam" site affect my other sites on the same IP?
I have a link directory called Liberty Resource Directory. It's the main site on my dedicated IP, all my other sites are Addon domains on top of it. While exploring the new MOZ spam ranking I saw that LRD (Liberty Resource Directory) has a spam score of 9/17 and that Google penalizes 71% of sites with a similar score. Fair enough, thin content, bunch of follow links (there's over 2,000 links by now), no problem. That site isn't for Google, it's for me. Question, does that site (and linking to my own sites on it) negatively affect my other sites on the same IP? If so, by how much? Does a simple noindex fix that potential issues? Bonus: How does one go about going through hundreds of pages with thousands of links, built with raw, plain text HTML to change things to nofollow? =/

"Fourth-level" subdomains. Any negative impact compared with regular "third-level" subdomains?
Hey moz New client has a site that uses: subdomains ("third-level" stuff like location.business.com) and; "fourth-level" subdomains (location.parent.business.com) Are these fourth-level addresses at risk of being treated differently than the other subdomains? Screaming Frog, for example, doesn't return these fourth-level addresses when doing a crawl for business.com except in the External tab. But maybe I'm just configuring the crawls incorrectly. These addresses rank, but I'm worried that we're losing some link juice along the way. Any thoughts would be appreciated!

Using the word "FREE" in domain name
Hi, This may seem like a simple question but a new client of mine wishes to use a domain name with the word "free" in it. The website will offer free activity vouchers. I couldn't see this being a problem as there a lot of websites that do this although he was told it may present a problem with the search engines thinking the site was spammy. It won't be and will be offering information and vouchers on local sporting activities. I was wondering if anybody could clarify this please so I can give him a more definitive answer to his question. Thanks for your help.

Wordpress "incoming search terms" plugin
Hello everyone! newbie to SEO and have been trying to keep everything nice and ethical but I've seen on a couple of blogs today "incoming search terms" at the bottom of the blogs, then a bullet pointed list of search terms beneath it. So I had a quick search about the use of it and noticed wordpress has a plugin that automatic ally generates these "incoming search terms". I ask is this a legitimate plugin or will this harm my blog? I assume it generally will as I can't see this being much use for the audience, rather it would be 100% for trying to lure in search engines.

Why crawl error "title missing or empty" when there is already "title and meta desciption" in place?
I've been getting 73 "title missing or empty" warnings from SEOMOZ crawl diagnostic. This is weird as I've installed yoast wordpress seo plugin and all posts do have title and meta description. But why the results here.. can anyone explain what's happening? Thanks!! Here are some of the links that are listed with "title missing, empty". Almost all our blog posts were listed there. http://www.gan4hire.com/blog/2011/are-you-here-for-good/ http://www.gan4hire.com/blog/2011/are-you-socially-awkward/

What is best practice for redirecting "secondary" domain names?
For sites with multiple top-level domains that have been secured for a business or organization, I'm curious as to what is considered best practice for setting up 301 redirects for secondary domains. Is it best to do the 301 redirects at the registrar level, or the hosting level? So that .net, .biz, or other secondary domains funnel visitors to the correct primary/main domain name. I'm looking for the "best practice" answer and want to avoid duplicate content problems, or penalties from the search engines. I'm not trying to game the system with dozens of domain names, simply the handful of domains that are important to the client. I've seen some registrars recommend hosting secondary domains, and doing redirects from the hosting level (and they use meta refresh for "domain forwarding," which I want to avoid). It seems rather wasteful to set up hosting for a secondary domain and then 301 each URL.
