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.

Reusing an already 301 redirected URL for a very important keyword
I have a question about reusing an already 301 redirected URL Till now I never reused an URLs that has been already redirected with a 301 redirect. However, I just started working on a website where in past they created a lot of 301 redirects without thinking about the future, and now certain URLs, that are currently redirected with a 301, would be very useful (exact match) and needed (for some of the most important keywords for this specific business), to maintain an optimal, homogeneous and "beautiful" URL structure. Has any of you ever reused a URL that was previously redirected with a 301 redirect? If yes what are your experiences with it? Can content on the reused URL (that was previously 301 redirected and than the redirect removed) normally rank if the page is reestablished and the redirect is removed (and you do great content, on page, internal linking, backlinking, .... ) or is such an URL risky / not recommended / "burned" forever and not recommended to be reused again... especially for very important keywords since it present the exact match ?! Thank you very much for all your help! Regards

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!

My homepage redirects to itself?
Hi there - I'm not a SEO so help would be appreciated! Moz is telling me we have a redirect loop but the URLs are the same. https://www.example.com/ to https://www.example.com/ Why is my homepage creating a redirect loop to itself? We use Wordpress and I do not have any redirects listed for our homepage. Could this have something to do with switching to https in April? Thanks, Katherine

301 redirect adding trailing slash to url
I am looking into a .htacess file for a site I look after and have noticed that the urls are all 301 redirecting from a none slash directory to a trailing slashed directory/folders. e.g. www.domain.com/folder gets 301 redirected to www.domain.com/folder/ Will this do much harm and reduce the effect on the page and any links pointing to the site be lessened? Secondly I am not sure what part of my htaccess is causing the redirect. RewriteCond %{HTTP_HOST} !^www.domain.co.uk [NC] RewriteCond %{HTTP_HOST} !^$

RewriteRule ^(.*) http://www.domain.co.uk/$1 [L,R,NE] RewriteCond %{THE_REQUEST} ^./index.php
RewriteRule ^(.)index.php$ /$1 [R=301,L] or could a wordpress ifmodule be causing the problem? Any info would be apreciated.0 -
Redirect typo domains
Hi, What's the "correct" way of redirecting typo domains? DNS A record goes to the same ip address as the correct domain name Then 301 redirects for each typo domain in the .htaccess Subdomains on typo urls still redirect to www or should they redirect to the subdomain on the correct url in case the subdomain exists?

How do I deindex url parameters
Google indexed a bunch of our URL parameters. I'm worried about duplicate content. I used the URL parameter tool in webmaster to set it so future parameters don't get indexed. What can I do to remove the ones that have already been indexed? For example, Site.com/products and site.com/products?campaign=email have both been indexed as separate pages even though they are the same page. If I use a no index I'm worried about de indexing the product page. What can I do to just deindexed the URL parameter version? Thank you!

Redirect URLS with 301 twice
Hello, I had asked my client to ask her web developer to move to a more simplified URL structure. There was a folder called "home" after the root which served no purpose. I asked for the URLs to be redirected using 301 to the new URLs which did not have this structure. However, the web developer didn't agree and decided to just rename the "home" folder "p". I don't know why he did this. We argued the case and he then created the URL structure we wanted. Initially he had 301 redirected the old URLS (the one with "Home") to his new version (the one with the "p"). When we asked for the more simplified URL after arguing, he just redirected all the "p" URLS to the PAGE NOT FOUND. However, remember, all the original URLs are now being redirected to the PAGE NOT FOUND as a result. The problems I see are these unless he redirects again: The new simplified URLS have to start from scratch to rank 2)We have duplicated content - two URLs with the same content Customers clicking products in the SERPs will currently find that they are being redirect to the 404 page. I understand that redirection has to occur but my questions are these: Is it ok to redirect twice with 301 - so old URL to the "p" version then to final simplified version. Will link juice be lost doing this twice? If he redirects from the original URLS to the final version missing out the "p" version, what should happen to the "p" version - they are currently indexed. Any help would be appreciated. Thanks
