Mobile URL parameter (Redirection to desktop)
-
Hello,
We have a parallel mobile website and recently we implemented a link pointing to the desktop website. This redirect is happening via a javascript code and results in a url followed by this paramenter: ?m=off
Example:
http://www.m.website.com redirects to:
http://www.website.com/?m=offQuestions:
- Will the "http://www.website.com/?m=off" be considered duplicate content with "http://www.website.com" since they both return the same content?
- Is there any possibility that Google will take into consideration the url ending in "/?m=off"? How should we treat this new url?
- The webmaster tools URL parameter configuration at the moment isn't experiencing problems but should we submit the parameter anyway in order not to be indexed or should we wait first and see the error response?
- In case we should submit this for removal... what's the best way to do it? Like this?
- Parameter: ?m=off
- Does this parameter change page content seen by the user? - doesn't affect page content
Any help is much appreciated.
Thank you! -
Hi again!
It's normal that you feature very similar or even, duplicate content through both your mobile and desktop Website versions, what it is fundamental though is that you use the rel alternate and canonical tags that I shared with you in my previous answer. I've just checked your site and you're not using them.
If you correctly add these tags in your mobile and desktop URLs as I described in my previous answer you shouldn't have any content duplication or cannibalization issues in Google's search results.
Thanks!

Thanks Aleyda, mobile website development is something new for and since we developed this in house, we are not sure if we have done the right thing, if we have duplicate content. Is there any way we can check for duplicate content? Could you take a look at our website and its mobile version and let us know what you think?
Thank you!

Hi there!
It's ok (and needed) in these circumstances to use a parameter in the URL since you cannot simply add a direct link otherwise your mobile users who select to switch to the desktop version will end-up in a redirection loop. What you can do to avoid any type of content duplication issues in this type of settings is:
- Add a link rel="alternate" tag in each of the desktop URLs referring to their specific mobile URL versions and a link rel="canonical" tag in all of the mobile URLs referring to their specific desktop URLS versions, as specified here by Google. Take a look at an example here
- Configure the appropriate canonical tags in your Desktop URLs as specified here by Google, so they always refer to their original URL versions (without parameters). This means that in http://www.website.com/?m=off you should add this canonical tag:```
pointing to its original URL version... and do this with every URL (referring to its own original URL version).
By doing this you won't have any content duplication issues. If you want to learn more about Mobile SEO take a look at the Webinar I did sometime ago in SEOmoz here and this post where I answer the most common Mobile SEO questions.
Thanks,
Aleyda

The page ending in ?m=off is non existent. We are using Joomla and such page does not exist and cannot be configured via canonical tags. Any other suggestion?
Thank you!

Query parameters can become indexed by Google and can lead to duplicate content. Just make sure that you are using the canonical tag in your header pointing to the non-query parameter page, that way Google will know to index the proper URL.

Redirection chain and Javascript Redirect
Hi, A redirection chain is usually defined as a page redirecting to another page which itself is another redirection. URL1 ---(301/302)---> URL2 ---(301/302)---> URL3 But what about Javascript redirect? They seem to be a different beast: URL1 ---(301/302)---> URL2 ---(200 then Javascript redirect)---> URL3 From what I know if the javascript redirect is instant Google counts it as a 301 permanent redirection, but I'm still not sure about if this counts as a redirection chain. Most of the tools (such as moz) only see the first redirection. So is that scenario a redirection chain or no?

How do you fix redirect chains and temporary redirects?
Hi, I have a lot of issues popping up with temporary redirects and redirect chains. I'm still confused as to what exactly redirect chains are and I don't know how to find where the "chains" are or how to fix them. I'm having two issues mainly:1. Temporary RedirectsI have around 100 pages on our www.twowayradiosfor.com website that are being flagged as temporary redirects. All of them have one thing in common: they are review pages (basically, when a customer clicks on the Review button to review a certain product, they are redirected to a review page for that product).URL Example: https://www.twowayradiosfor.com/reviewhelpful.asp?ProductCode=CLS1410-COMBO&ID=44&yes=noI went into our website and set any URL containing the following as noindex:/review.aspWill that fix the issue? If yes, will I also need to do that for any URL containing /reviewhelpful.asp?2. Redirect ChainsIt seems like basically every product page on my website has this issue (over 100 pages). Here's an example of one:https://www.twowayradiosfor.com/Motorola-CLS1110-p/cls1110.htmI don't see any broken links on this page or links that redirect to another page that redirects, etc. What is causing this? Is it something on my header bar that is redirecting (since that header bar appears on every page, maybe that is why this issue shows up on a lot of pages)?I am new to Moz and still trying to figure this stuff out. I really appreciate any help. Thanks, Sawyer

I have a question about the impact of a root domain redirect on site-wide redirects and slugs.
I have a question about the impact (if any) of site-wide redirects for DNS/hosting change purposes. I am preparing to redirect the domain for a site I manage from https://siteImanage.com to https://www.siteImanage.com. Traffic to the site currently redirects in reverse, from https://www.siteImanage.com to https://siteImanage.com. Based on my research, I understand that making this change should not affect the site’s excellent SEO as long as my canonical tags are updated and a 301 redirect is in place. But I wanted to make sure there wasn’t a potential consequence of this switch I’m not considering. Because this redirect lives at the root of all the site’s slugs and existing redirects, will it technically produce a redirect chain or a redirect loop? If it does, is that problematic? Thanks for your input!

Is there a tool to see all redirects?
I'm thinking this is a silly question, but I've never had to deal with it I thought I'd ask. Ok is there a tool out there that will show all the redirects to a domain. I'm working on a project that I keep stumbling on urls that redirect to the site I'm studying. They don't show up in Open Site or ahrefs as linking domains, but they keep popping up on me. Any thoughts?

Does it really matter to maintain 301 redirect after de-indexing of old URLs?
Today, I was reading latest blog post on SEOmoz blog about. Uncrawled 301s - A Quick Fix for When Relaunches Go Too Well This is very interesting study about 301 & How it useful to maintain traffic. I'm working on eCommerce website and I have done similar stuff on my website. I have big confusion to manage 301 redirect. My website generates new URLs due to following actions. Re-write dynamic URLs. Re-launch entire website on different eCommerce platform. [osCommerce to Magento Commerce] Re-name category. Trasfer one product from one category to another category. I'm managing my 301 redirect with old practice. Excel sheet data from Google webmaster tools and set specific new URLs for redirect. Hoooo... Now, I have 8.5K redirect in htaccess... And, I'm thinking it's too much. Can we remove old 301 redirect from htaccess or not? This is big question for me. Because, all pages are not hyperlink on external website. Google have just de-indexed old URLs and indexed new URLs. So, Is it require to maintain 301 redirect after Google process?

Redirect non-www if using canonical url?
I have setup my website to use canonical urls on each page to point to the page i wish Google to refer to. At the moment, my non-www domain name is not redirected to www domain. Is this required if i have setup the canonical urls? This is the tag i have on my index.php page rel="canonical" href="http://www.mydomain.com.au" /> If i browse to http://mydomain.com.au should the link juice pass to http://www.armourbackups.com.au? Will this solve duplicate content problems? Thanks

What tools produce a complete list of all URLs for 301 redirects?
I am project managing the rebuild of a major corporate website and need to set up 301 redirects from the old pages to the new ones. The problem is that the old site sits on multiple CMS platforms so there is no way I can get a list of pages from the old CMS. Is there a good tool out there that will crawl through all the sites and produce a nice spreadsheet with all the URLs on it? Somebody mentioned Xenu but I have never used it. Any recommendations? Thanks -Adrian

If a redirecting URL has more value than the website should I move it?
Client has two website addresses: Website A is a redirect to Website B. It has one indexed page. But this is the URL being used in collateral. It has the majority of back links, and citations everywhere list Website A as the URL. Website B is where the actual website lives. Google recognizes and indexes the 80+ pages. This website has very few backlinks going to it. This setup does not seem good for SEO. Moreover, the analytics data is completely messed up because Website B shows that the biggest referral source is... you guessed it Website A. I'm thinking going forward, I should: Move all the content from Website B to Website A. Setup Website B to permanently 301 Redirect to Website A. Is that the best course of action?
