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.

Good to use disallow or noindex for these?
Hello everyone, I am reaching out to seek your expert advice on a few technical SEO aspects related to my website. I highly value your expertise in this field and would greatly appreciate your insights.
Technical SEO | | williamhuynh
Below are the specific areas I would like to discuss: a. Double and Triple filter pages: I have identified certain URLs on my website that have a canonical tag pointing to the main /quick-ship page. These URLs are as follows: https://www.interiorsecrets.com.au/collections/lounge-chairs/quick-ship+black
https://www.interiorsecrets.com.au/collections/lounge-chairs/quick-ship+black+fabric Considering the need to optimize my crawl budget, I would like to seek your advice on whether it would be advisable to disallow or noindex these pages. My understanding is that by disallowing or noindexing these URLs, search engines can avoid wasting resources on crawling and indexing duplicate or filtered content. I would greatly appreciate your guidance on this matter. b. Page URLs with parameters: I have noticed that some of my page URLs include parameters such as ?variant and ?limit. Although these URLs already have canonical tags in place, I would like to understand whether it is still recommended to disallow or noindex them to further conserve crawl budget. My understanding is that by doing so, search engines can prevent the unnecessary expenditure of resources on indexing redundant variations of the same content. I would be grateful for your expert opinion on this matter. Additionally, I would be delighted if you could provide any suggestions regarding internal linking strategies tailored to my website's structure and content. Any insights or recommendations you can offer would be highly valuable to me. Thank you in advance for your time and expertise in addressing these concerns. I genuinely appreciate your assistance. If you require any further information or clarification, please let me know. I look forward to hearing from you. Cheers!0 -
Should we Nofollow Social Links?
I've been asked the question of whether if we should nofollow all of our social links, would this be a wise thing to do? I'm not exactly getting a clear answer from search results and thought you guys would be best to ask 🙂 Thanks in advance.

Rel=canonical Weebly
My problem is with my website as it says I have duplicate page titles and contents because of a /index.html. It says the duplicate content is due to the fact that my homepage on my website is www.seacandytackle.com but it is also www.seacandytackle.com/index.html because I use weebly. How can I use the tag to fix this? It won't let me do a 301 redirect because it is a home page. How can I fix this? What code would I have to use and which url? Also it says that I have duplicate page content between http://www.seacandytackle.com/index.html and http://www.seacandytackle.comhttp://www.seacandytackle.com but I don't recall having any page that looks like http://www.seacandytackle.com http://www.seacandytackle.com from weebly. How can I fix this issue as well? Thank you for any help. Step by step implementation would be particularly helpful in using the rel= tags to fix these duplicate issues.

Staging site and "live" site have both been indexed by Google
While creating a site we forgot to password protect the staging site while it was being built. Now that the site has been moved to the new domain, it has come to my attention that both the staging site (site.staging.com) and the "live" site (site.com) are both being indexed. What is the best way to solve this problem? I was thinking about adding a 301 redirect from the staging site to the live site via HTACCESS. Any recommendations?

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.

Using a non-visible H1
I have a developer that wants to use style="text-indent:-9999px" to make the H1 non-visible to the user. Being the conservative person I am, I've never tried this before and worry that Search Engines may think this is a form of cloaking. Am I worrying about nothing? And apologies if it's already been covered here. I couldn't find it. Thanks in advance!!!!

How valuable is content "hidden" behind a JavaScript dropdown really?
I've come across a method implemented by some SEO agencies to fill up pages with somehow relevant text and hide it behind a javascript dropdown. Does Google fall for such cheap tricks? You can see this method used on these pages for example (just scroll down to the bottom) - it's all in German, but you get the idea I guess: http://www.insider-boersenbrief.de/ http://www.deko-und-kerzenshop.de/ How is you experience with this way of adding content to a site? Do you think it is valuable or will it get penalised?

Is "last modified" time in XML Sitemaps important?
My Tech lead is concerned that his use of a script to generate XML sitemaps for some client sites may be causing negative issues for those sites. His concern centers around the fact that the script generates a sitemap which indicates that every URL page in the site was last modified at the exact same date and time. I have never heard anything to indicate that this might be a problem, but I do know that the sitemaps I generate for other client sites can choose server response or not. What is the best way to generate the sitemap? Last mod from actual time modified, or all set at one date and time?
