Welcome to the Q&A Forum

Have you logged into Google Webmaster Tools and looked for any notices? Having a duplicate website isn't a great thing, but let's make sure that there's also not some other cause. Was anything done to the code of the site? Any robots.txt or meta robots changed? Are you still fine in Bing/Yahoo?

I like to prepare in advance for future Algo Changes. With that said it is probably best not to get into the habit of putting the same 3 links on the blog post. Blog links aren't that valuable Most are set to no follow anyways If on same C-Block, will eventually be a red flag,  if not now then in the future. It is best to stick to the White Hat techniques. I just think about it this way. If my business is my website and I finally start generating a nice income from it and I violate some rule that shuts me down, how will that impact my lifestyle?

Or you could do <title>Red Tonka Firetruck | 10659 Toys In Stock</title> The important thing is the uniqueness of each, the 1st part needs to be the primary focus of the page, and you want to communicate "this page really is about the topic you searched for"...

Google knows u own both sites. Don't interlink them unless you are doing it to point someone to the other site for a store or something like that. In that case nofollow all of the links and you'll be fine. If you are doing it to try and pass PR and boost you rankings then don't do it or both sites could get penalized.

Keep them. The more content the better plus the pages probably accrued PR as long as it's accurate info and not outdated. If these pages have PR you might want to consider streamlining the links on these pages to pass PR to the homepage or main landing pages.

Marcus is dead on.

There could be many causes, but generally speaking, mobile SEO is constantly changing as more and more sites migrate to mobile.  At a much higher rate than new sites come on the desktop scene.  So the competition is continually growing.  If you have a mobile specific site, you need to understand that you need to continually work on your mobile-specific SEO to deal with that competition, and as Google does more and more to properly identify the best sites to show in mobile results.

Assuming these are all on the same domain (not separate subdomains), simply permanently redirect the URLs to an existing or new upper-level category page, which most closely matches the removed content. There's no perfect solution, but that's better than all 404 errors, especially if there are good links to those old pages. Good luck.

John Muller from Google published a good set of specifications for this. Maybe it will help. https://sites.google.com/site/webmasterhelpforum/en/faq-internationalisation There are several points in this list that you could check and double check (translations, currency, mentions of the target countries and so on). Hope it helps. If not and you have a more specific agenda get back with a reply here.

The first place I would start is by looking at what links you have to that page using OSE - http://www.opensiteexplorer.org/. If you don't have many decent links to that page you need to start looking at ways you can build these links through methods such as competitions, social media (build an audience/following and build relationships with authority figures for your niche, then you can put your great content in front of them for the exposure and links will come), informative articles about the brand and products, etc. There are lots of decent ideas and guides to building links on here so I won't reiterate them, just search for link building on here. You also need to look at your domain authority and how many decent links you have for that. Essentially on-page factors only act as a guide to what your content is about but links indicate this information is worth reading so improving you link profile will increase your rankings for keywords. Remember Great content + exposure = links Links give authority and help increase your rankings in the SERPs Hope this helps

something like this is very difficult to determine without the URL and being able to look at the sites. you sound like you know what you're doing so I assume you made sure your robots.txt wasn't accidentally updated to block your site or that you have noindex tags on the pages by mistake.

Thanks for the answer, but no, nothing mentioned happened.

Without examining your site I am left to guess. If you use WordPress or any other form of CMS or software, you may have pages you are not aware of. A crawl would need to be performed to discover those pages and/or relevant links. It is possible the canonical tag does not appear on those pages. Also, keep in mind the canonical tag is a recommendation to Google. They do not always follow it. I would not recommend using the canonical tag to cover up site issues.

**google bot crawled our new pages yesterday, canonical tag was placed maybe week ago. ** The canonical tag which is providing the adjustment is the one on the old page, not the new one. In order to fully update Google needs to crawl both the old and new pages. So it should see this tag, but looks like they ignore this tag. That is not true. Your understanding of how the process works is not complete. You are not using the best solution and you are expecting results way too fast. 301 redirection is not good idea as we loose ~10% of link juice, that's why it's recommended to use canonical. You lose a small amount of link juice when performing a redirect. That amount is estimated as between 1 and 10%. You lose the same amount when using a canonical tag. All of the above information is correct, but I sense you are convinced otherwise so perhaps this video from Matt Cutts will change your mind: http://www.youtube.com/watch?v=zW5UL3lzBOA

Hi Valdas, It depends if you would like to keep the content and rankings achieved from the individual sites. I would imagine this is important, in which case I think the best approach would be to transfer the sites from their current domains into the subfolders on the new domain. This way each page would still exist but just on the new domain e.g. www.newdomain.com/site1/post-1 This would then leave all the content in place and allow you to capture all the long tail traffic you were getting before. To do this would be more time consuming as you would need to 301 redirect each individual URL to the new URL but it would help you to make the most of the work you have done on each of the individual sites.

That's correct - having both www.site.com and just site.com causes duplication issues. You do not need to have redirects in place to solve this though - you can use a rel=canonical tag in order to specify which 'version' you wish search engines to use. Here are a few posts that should help you: Google's Explanation - http://support.google.com/webmasters/bin/answer.py?hl=en&answer=139394 SEOmoz Best Practices - http://www.seomoz.org/learn-seo/canonicalization John Doherty's blog post - "Should I use a Rel=Canonical or 301 Redirect?" - http://www.johnfdoherty.com/relcanonical-301-redirect/

Hi, The keyword closer to the root has a slight better impact but in some cases the subdomain can be considered by Google as separate items / domains so all teh DOmain authority from the main domain won't be passed. That is only in some cases when the domain has a totally different content, score, user flow etc. However since you can not control if Google will consider your subdomain as a separate item it is somehow risky. Personally I am always going with the folder - always. (just to be safe and to get the maximum out of any links to the domain) Hope it helps.

Yes, those links will still pass most of the juice. Matt Cutts has said in one of his videos that doing a 301 redirect passes almost all of the link juice, a very tiny bit is lost, which is not a concern. No need to worry
