Is it ok to add rel=CANONICAL into the desktop version on top of the rel="alternate" Tag (Mobile vs Desktop version)
-
Hi mozzers,
We launched a mobile site a couples months ago following the parallel mobile structure with a URL:m.example.com
The week later my moz crawl detected thousands of dups which I resolved by implementing canonical tags on the mobile version and rel=alternate onto the desktop version. The problem here is that I still also got Dups from that got generated by the CMS.
?device=mobile
?device=desktop
One of the options to resolve those is to add canonicals on the desktop versions as well on top of the rel=alternate tag we just implemented. So my question here:
is it dangerous to add rel=canonical and rel=alternate tags on the desktop version of the site or not? will it disrupt the rel=canonical on mobile?
Thanks

Hi Taysir,
Great question! Honestly, I'm not confident what would happen if you add the rel=canonical and rel=alternate tags to the desktop version (and whether that will disrupt the rel=canonical on mobile or not). My advice is to test it out on a few select pages (I would recommend not testing your most important/highest revenue driving pages first, but on less critical pages) and see how the search engines deal with these pages. If the duplicates are removed and traffic to the mobile site isn't affected, then I would start scaling the rel=canonical out on other pages. However if you do see an issue with the combination of rel=canonical and rel=alternate on the desktop version, then it may be worth fixing the CMS, so that it no longer creates these duplicate pages.
Best,
Stephanie

Only the mobile version of the site is being indexed
We've got an interesting situation going on at the moment where a recently on-boarded clients site is being indexed and displayed, but it's on the mobile version of the site that is showing in serps. A quick rundown of the situation. Retail shopping center with approximately 200 URLS Mobile version of the site is www.mydomain.com/m/ XML sitemap submitted to Google with 202 URLs, 3 URLS indexed Doing site:www.mydomain.com in a Google search brings up the home page (desktop version) and then everything else is /m/ versions. There is no rel="canonical" on mobile site pages to their desktop counterpart (working on fixing that) We have limited CMS access, but developers are open to working with us on whatever is needed. Within desktop site source code, there are no "noindex, nofollow, etc" issues on the pages. No manual actions, link issues, etc Has anyone ever encoutnered this before? Any input or thoughts are appreciated. Thanks

SEO Concerns From Moving Mobile M Dot site to Responsive Version?
I currently have my mobile site set up as a m dot site. I have designed a new responsive/adaptive version of my desktop site I would like to start using. When I search from google on mobile, my website is indexed as the m dot site. When I make the switch, this will no longer be the case as I will only have one url for both mobile and desktop. The m dot url's will no longer work. Are there any SEO consequences from making this shift?

Rel=next/prev for paginated pages then no need for "no index, follow"?
I have a real estate website and use rel=next/prev for paginated real estate result pages. I understand "no index, follow" is not needed for the paginated pages. However, my case is a bit unique: this is real estate site where the listings also show on competitors sites. So, I thought, if I "no index, follow" the paginated pages that would reduce the amount of duplicate content on my site and ultimately support my site ranking well. Again, I understand "no index, follow" is not needed for paginated pages when using rel=next/prev, but since my content will probably be considered fairly duplicate, I question if I should do anyway.

Taking up an "abondoned" domain?
Hi, As far as SEO goes, are there any direct contradictions to picking up an approximately 1 year old domain, where the only thing that has ever been on is a static "Hello world" page from a wordpress install done when the domain was created? I'm thinking about picking it up again, as if it was a totally fresh domain, add content, and do SEO on it. What are your thoughts friends? Thanks.

What does this kind of rel="canonical" mean?
It looks like our CMS may not be configured correctly as there is an empty section in the rel="canonical" rel="canonical" href="{page_uri}" /> Will having the above meta tag be harmful to our SEO?

Disabling a website - What to do with "link juice"?
Hi I built a website for a client a long time ago now and for a number of reasons I have decided to shut down the website. None payment being one of the reasons! My question to all you SEO guru's out there is, what should I do with 301 redirects. The site is an e-commerce based website and my personal website is simply advertising my services and portfolio. If I 301 redirect all the traffic from the customer website, will there be any issue with Google (or any search engine) seeing that my website is receiving traffic for search phrases such as "Coffee Mugs"? I.e. abolutely no relevance at all to my website content! My worry is my site could be penalised for a flurry of thousands of redirected links. Also, if I redirect everything to my site and the customer decides to pay the bill in due course, I will then remove the redirects - I guess this will have a massive impact on the rankings of the site? Thanks for reading and any advice.

"Iffy" Question
Hi Guys and Girls, I have been studying SEO for a few years now. I have learned quite a bit along the way. One thing that I have had BEAT in my head is "Create Quality Content". When I used to ask "What Should I do to get more visits?" I was told, "Create QUALITY CONTENT". That was great advice, and I have done that. I have created over 600 pages since then. I went from 200 visits per month to now just over 5,000. Even more importantly, I have increased my lead conversions. I say all of this because, about two years ago I told a competitor basically how you rise up in the search engines. He turned around and bought a domain that was 3 years older than mine and had a main keyword in the domain. He then just started building links with a bunch of blog comments and forum posts (The blog comments have like 2,000 comments on them). In other words, he did what I would NOT do yet he is #5 for this keyword and I am #9. (Although, I turned around and built another site and now I am at #13 for that and it has been up for a year now. I say all this, not to bore you but to tell ask you, DOES IT WORK IF YOU DO BLOG COMMENTING, FORUM POSTING, LINK WHEELS, ETC. Do you obtain higher rankings? Should I be doing a bit of video marketing? I know a lot of people will say, "Why would you spend your time on things that may slightly impact your rankings, but obviously it did something for this guy. Any help you can give would be greatly appreciated.

Duplicate Content, Campaign Explorer & Rel Canonical
Google Advises to use Rel Canonical URL's to advise them which page with similiar information is more relevant. You are supposed to put a rel canonical on the non-preferred pages to point back to the desired page. How do you handle this with a product catalog using ajax, where the additional pages do not exist? An example would be: <colgroup><col width="470"></colgroup>

| .com/productcategory.aspx?page=1 /productcategory.aspx?page=2 /productcategory.aspx?page=3 /productcategory.aspx?page=4 The page=1,2,3 and 4 do not physically exist, they are simply referencing additional products I have rel canonical urls' on the main page www.examplesite.com/productcategory.aspx, but I am not 100% sure this is correct or how else it could be handled. Any Ideas Pro mozzers? |0
