Does using data-href="" work more effectively than href="" rel="nofollow"?

[JDatSB]

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>

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.

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>
