Multiple Versions of Mobile Site
-
Hey Guys,
We have recently finished the latest version of our mobile site which means currently we have 2 mobile sites. Depending on what device and Os will depend on which site you will be presented with.
e.g.
iPhone 3 or 4 users on iOS4 will get version 1 of our mobile site
iPhone 5 users on iOS5 will get the new version (version 2) of our mobile site.Our old mobile site is currently indexed in Google and performing pretty well.
Since the launch of the second mobile site we have not see any major changes to our visibility in Google and so was curiousMy main concern here is duplicate content so I am curious can Google detect that we have 2 mobile site that we serve depending on device? And if Google can detect this, why has our sites not been penalized!
Thanks,
LW
I know the first thing that comes to your mind is Duplicate content

Hi LW,
Sorry for the extreme delay here - the Q&A notification system went wonky for a bit and I never got the response message for this thread.
I'm sure you're passed this issue by now, but yes - Googlebot Mobile should just index the mobile version of the page.
Best,

Hey Mike,
Thanks for your feedback, it is really helpful.
We are serving up unique source code on the same URL per device, with the user agent being detected on the server-side.
Am I right in assuming that he Googlebot Mobile will only see one version of the pages and index accordingly?
Cheers,
LW

Hi LW,
I'm wondering about some particulars of your setup for this.
How are URLs handled between the three sites (1 desktop, 2 mobile)?
Are you serving up unique source code on the same URL per device, or do you have device-specific URLs for all content?
What are you using to detect the useragent and redirect the user? Is this happening server-side, or with JavaScript?
The particulars of your setup will determine your best approach. When in doubt I would follow the instructions on this page.
I would not expect two mobile versions of your site to cause a duplicate content issue - more likely that Googlebot Mobile will only see one version of the pages and index those (but as above, the technical particulars will determine this).
Best,
Mike -
Thanks for your response, You raise a very valid point about the time taken for Google to index it. The new site has been live for a couple of weeks now, so I was hoping to see the new site to be starting to get indexed by Google by now!
In regards to rel="canonical", Yes we have implemented on the mobile site referencing the desktop site.
Reason behind developing a new version rather than just updating the previous version was because we had new functionality to include and a fair few changes to design based on learning from the old site. That being said code from the first site was still being used so it wasn't a completely new build.

If you have only just launched the new version of your mobile site, it may take some time before Google indexes it and detects that there are duplicate content with your previous version. Google bot doesn't crawl all new sites instantly.
Just wondering, have you done anything to prevent duplicate content penalty, such as using rel="canonical" tag? Also, why not update your previous version instead of creating a different mobile site entirely?

Google URL Shortener- Should I use one or multiple???
I have a client with a number of YouTube videos. I'm using Google URL Shortner to allow the link to show in the YouTube text (as its a long URL). Many of these links go to the same page ex .com/services-page Should I use a single short URL for each video linking to the .com/services-page or should they be unique each time? If unique, would Google possibly think I'm trying to manipulate results? Thanks in advance. I'm just not sure on this one and hope someone knows best practice on this. Thanks!

Preventing CNAME Site Duplications
Hello fellow mozzers! Let me see if I can explain this properly. First, our server admin is out of contact at the moment,
White Hat / Black Hat SEO | | David-Kley
so we are having to take this project on somewhat blind. (forgive the ignorance of terms). We have a client that needs a cname record setup, as they need a sales.DOMAIN.com to go to a different
provider of data. They have a "store" platform that is hosted elsewhere and they require a cname to be
sent to a custom subdomain they set up on their end. My question is, how do we prevent the cname from being indexed along with the main domain? If we
process a redirect for the subdomain, then the site will not be able to go out and grab the other providers
info and display it. Currently, if you type in the sales.DOMAIN.com it shows the main site's homepage.
That cannot be allow to take place as we all know, having more than one domain with
exact same content = very bad for seo. I'd rather not rely on Google to figure it out. Should we just have the cname host (where its pointing at) add a robots rule and have it set to not index
the cname? The store does not need to be indexed, as the items are changed almost daily. Lastly, is an A record required for this type of situation in any way? Forgive my ignorance of subdomains, cname records and related terms. Our server admin being
unavailable is not helping this project move along any. Any advice on the best way to handle
this would be very helpful!0 -
Bad keywords sending traffic my site, but can't find the source. Advice?
Hi! My site seems to be the target of negative SEO (or some ancient black hat work that's just now coming out of the woodwork). We're getting traffic from keywords like "myanmar girls" and "myanmar celebrities" that just started in late June and only directs to our homepage. I can't seem to find the source of the traffic, though (Analytics just shows it as "Google," "Bing," and "Yahoo" even though I can't find our site showing up for these terms in search results). Is there any way to ferret out the source besides combing through every single link that is directing to us in Webmaster Tools? I'm not even sure that GWT has picked up on it since this is fairly new, and I'd really love to nip this in the bud. Thoughts? Thanks in advance!

Untrusted site - malware!
I recently had my link profile done as I was badly effected by something in 2012 (Penguin, Panda.. who knows? never got a message from google in webmaster about anything). Loads of INBOUND links were identified as being 'dodgy'' and the person highlighted them in different colors. However, another seo éxpert' told me to leave them (perhaps remove just 3 of them) and don't bother with the rest. Now I am not sure what to do? Any opinions? RED

3 were highlighted as being from untrusted malware. I think I should disavow them but really, would 3 make that much difference for a fall in my site? ORANGE
240 were said to be spam articles and I was advised:
The following pages highlighted in orange are on sites created for the purpose of publishing articles for link building. Since the same articles appear on multiple sites, Google views this as duplicate content. Links to Monteverde Tours in these articles should be removed or tagged "nofollow." Where this is not possible, the domains should be disavowed. YELLOW
85 were said to be from Low-quality directories
The following pages highlighted in yellow are on low-quality directories and link farms. Links to Monteverde Tours on these pages should be removed or the domains disavowed. GREEN
340 were said to be from sites were the page was not found , Account suspended, Problem loading page, Link removed, domain expired
The following pages highlighted in green include pages whose links to Monteverde Tours have been removed and pages that were inaccessible for various reasons, as shown in the Comments column. These pages or their domains should be disavowed to remove them from the Google index. I have read (and asked on this forum) about disavow but the more I read the more I am getting confused about the next action. I tried for one year to get rid of any bad outbound links, did blogging, social media, improved content, landing pages etc but all to no avail. Any opinions appreciated. I am not looking for a magic bullet, I know there isn't one. I know I need to keep improving content etc but after a year of NO improvements should I consider the link removal route? <colgroup><col width="215"></colgroup>

Has my site been penalized by google
Hi all I have noticed a sudden drop in rankings for most of my keywords on kerryblu ,co,uk and was thinking the site may have been manually penalized by google. I have not received any notification of this in webmaster tools but can't think of any other reason for the loss of rankings. I have searched the web for info on this but can't find a definite answer. Is there any way of knowing for sure. At the time of the crash the only real change I made was adding google adsense to my blog. Could this be responsible. Thanks for looking.

A friend of mine has a pagerank 3 website that links to all my pages on my site on every page of his site. The anchor text of all these links are the title of each page that it links to.

Should we add our site to Google Webmaster Tools
Hello, Should we add our site nlpca(dot)com to google webmaster tools? Everything's very white hat but we do have a section on each of our 4 sites for "Our other Sites" that link to the others. It's been there for many years. We're looking for clues as to why we've dropped in rank Thanks!
