Dropped ranking - Penguin penalty or duplicate content issue?
-
Just this weekend a page that had been ranking well for a competitive term fell completely out of the rankings. There are two possible causes and I'm trying to figure out which it is, so I can take action.
I found out that I had accidentally put a canonical on another page that was for the same page as the one that dropped out of the rankings. If there are two pages with the same canonical tag with different content, will google drop both of them from the index?
The other possibility is that this is a result of the recent Penguin update. The page that dropped has a high amount of exact anchor text. As far as I can tell, there were no other pages with any penalties from the Penguin update.
One last question: The page completely dropped from the search index. If this were a Penguin issue, would it have dropped out completely,or just been penalized with a drop in position?
If this is a result of the conflicting canonical tags, should I just wait for it to reindex, or should I request a reconsideration of the page?

Yes I think it was a Penguin drop. There is one other thing about the page that dropped. It is using a 301 re-direct. I had updated the page url a while ago, but nearly all of the links to the page are to the old page. So this penalty might be a combination of signals that collectively have tagged that page.
I'm working on cleaning up the link profile right now. I think that Penguin is a very imperfect animal. But I cant change the beast, so I will just have to make some changes here.

It's unlikely the canonical is to blame here, if I'm understanding it correctly. If you tried to canonicalize Page B to Page A, and they were clearly different, one of two things should happen:
(1) Google will just ignore it.
(2) Google will follow it anyway, and drop Page B from the index.
Now, it's theoretically possible that, if Google thought you were using the canonical tag inappropriately to benefit Page A, they could punish Page A, but I've honestly never seen that happen (I've seen it with 301-redirects). Typically, Page B would also have to have a lot of links that you were trying to "clean" (think money laundering). Since Page B is new, this seems very unlikely.
If you're hitting exact-match (or close to it) anchor text hard on Page A, it's certainly possible Penguin came into play, especially if Page A is pushing keywords a bit too hard. It's been tough to confirm Penguin cases, but most of the verified ones I've seen are sudden drops. It's not a subtle, gradual impact.
You could wait for the next Penguin data update, but I suspect you may have to do some link clean up. If there's anything that's not only exact-match anchor text but is sitewide (especially footer links), I'd start there. They seem to be major targets of Penguin. Truthfully, though, we're still collecting data on it.

Thanks for the reply!
What happened was that I added a new page and accidentally used the canonical for the page that was ranking well for search terms on that new page.
So to state it a different way - I added a new Page B to the site, but instead of using the canonical for that page, I accidentally used the canonical for Page A. Page A is the page that previously had ranked well for search terms. On Saturday night or Sunday, Page A dropped out of all of the search terms that it ranks for. However, I did a little more research and Page A is still in the index, it just doesnt rank for any of the search terms it used to. Page B is also in the index, but since it is a new page, it does not really rank for any terms. Obviously, I have fixed the canonical on Page B and Google already has the new page in its cache.
As far as over-optimization penalties, Page A has nearly all the inbound links with anchor text that is only a slight variation of the search term. It is the page on the site that I would have expected to have got hit by Penguin. There are some other pages that have lost a little bit of ranking, but nothing drastic.
I am just surprised that if it is a Penguin penalty, it would completely lose ranking on the terms in a single day, rather than moving down the rankings to maybe the third or fourth page. Do you find that Penguin penalties usually result in a lower ranking, or completely losing rankings?
Either way, I'm going to go in and clean up the link profile, but it would be nice to know how aggressive I should be to try to recover that page.

I've seen some reports of sites being hit by the Penguin data update ("Penguin 1.1") on Friday night, but I'm not clear on the severity. If it's just one page, though, and it was completely de-indexed, that's pretty unlikely.
It is definitely possible for a bad canonical tag to drop a page from the index. I'm a little confused on what you're saying about the two pages. Are they both canonical'ed to a third page, or to each other? Could you give an example (maybe show us two tags that are similar to what you have, but with the exact details changed)?

Content Strategy/Duplicate Content Issue, rel=canonical question
Hi Mozzers: We have a client who regularly pays to have high-quality content produced for their company blog. When I say 'high quality' I mean 1000 - 2000 word posts written to a technical audience by a lawyer. We recently found out that, prior to the content going on their blog, they're shipping it off to two syndication sites, both of which slap rel=canonical on them. By the time the content makes it to the blog, it has probably appeared in two other places. What are some thoughts about how 'awful' a practice this is? Of course, I'm arguing to them that the ranking of the content on their blog is bound to be suffering and that, at least, they should post to their own site first and, if at all, only post to other sites several weeks out. Does anyone have deeper thinking about this?

Fix Duplicate Content Before Migration?
My client has 2 Wordpress sites (A and B). Each site is 20 pages, with similar site structures, and 12 of the pages on A having nearly 100% duplicate content with their counterpart on B. I am not sure to what extent A and/or B is being penalized for this. In 2 weeks (July 1) the client will execute a rebrand, renaming the business, launching C, and taking down A and B. Individual pages on A and B will be 301 redirected to their counterpart on C. C will have a similar site structure to A and B. I expect the content will be freshened a bit, but may initially be very similar to the content on A and B. I have 3 questions: Given that only 2 weeks remain before the switchover - is there any purpose in resolving the duplicate content between A and B prior to taking them down? Will 301 redirects from penalized pages on A or B actually hurt the ranking of the destination page on C? If a page on C has the same content as its predecessor on A or B, could it be penalized for that, even though the page on A or B has since been taken down and replaced with a 301 redirect?

Duplicating relevant category content in subcategories. Good or bad for google ranking?
In a travel related page I have city categories with city related information.
Intermediate & Advanced SEO | | lcourse
Would you recommend for or against duplicating some relevant city related in subcategory pages. For visitor it would be useful and google should have more context about the topic of our page.
But my main concern is how this may be perceived by google and especially whether it may make it more likely being penalized for thin content. We already were hit end of june by panda/phantom and we are working on adding also more unique content, but this would be something that we could do additionally and basically instantaneously. Just do not want to make things worse.0 -

Duplicate content on subdomains
Hi All, The structure of the main website goes by http://abc.com/state/city/publication - We have a partnership with public libraries to give local users access to the publication content for free. We have over 100 subdomains (each for an specific library) that have duplicate content issues with the root domain, Most subdomains have very high page authority (the main public library and other local .gov websites have links to this subdomains).Currently this subdomains are not index due to the robots text file excluding bots from crawling. I am in the process of setting canonical tags on each subdomain and open the robots text file. Should I set the canonical tag on each subdomain (homepage) to the root domain version or to the specific city within the root domain? Example 1:
Intermediate & Advanced SEO | | NewspaperArchive
Option 1: http://covina.abc.com/ = Canonical Tag = http://abc.com/us/california/covina/
Option 2: http://covina.abc.com/ = Canonical Tag = http://abc.com/ Example 2:
Option 1: http://galveston.abc.com/ = Canonical Tag = http://abc.com/us/texas/galveston/
Option 2: http://galveston.abc.com = Canonical Tag = http://abc.com/ Example 3:
Option 1: http://hutchnews.abc.com/ = Canonical Tag = http://abc.com/us/kansas/hutchinson/
Option 2: http://hutchnews.abc.com/ = Canonical Tag = http://abc.com/ I believe it makes more sense to set the canonical tag to the corresponding city (option 1), but wondering if setting the canonical tag to the root domain will pass "some link juice" to the root domain and it will be more beneficial. Thanks!0 -
Duplicate content across hundreds of Local sites and they all rank #1
Usually when we discuss duplicate content, we're addressing the topic of penalties or non-indexing. In this case, we're discussing ranking high with duplicate content. I've seen lots of dental, chiropractor and veterinarian sites built by companies that give them cookie cutter sites with the same copy. And they all rank #1 or #2. Here are two companies that do that:
Intermediate & Advanced SEO | | katandmouse
http://www.rampsites.com/rampsites/home_standard.asp?sectionid=4
http://mysocialpractice.com/about/ The later uses external blogs to provide inbound links to their clients' site, but not all services do that, in fact, this is the first time I've seen them with external blogs. Usually the blog with duplicate copy is ON SITE and the sites still rank #1. Query "Why Your Smile Prefers Water Over Soft Drinks" to see duplicate content on external blogs. Or "Remember the Mad Hatter from the childhood classic, Alice in Wonderland? Back then, the process of making hats involved using mercury compounds. Overexposure could produce symptoms referred to as being" for duplicate content on chiropractor sites that rank high. I've seen well optimized sites rank under them even though their sites have just as much quality content and it's all original with more engagement and inbound links. It appears to me that Google is turning a blind eye on duplicate content. Maybe because these are local businesses with local clientele it doesn't care that a chiropractor in NY has the same content as one in CA, just as the visitor doesn't care because the visitor in CA isn't look at a chiropractor's site in NY generally. So maybe geo-targeting the site has something to do with it. As a test, I should take the same copy and put it on a non-geo-targeted site and see if it will get indexed. I asked another Local SEO expert if she has run across this, probably the best in my opinion. She has and she finds it difficult to rank above them as well. It's almost as if Google is favoring those sites. So the question is, should all dentists, chiropractors and veterinarians give it up to these services? I shudder to think that, but, hey it's working and it's a whole lot less work - and maybe expense - for them.0 -
Duplicate WordPress Home Page Issue
I have an issue where I've created a site, (www.tntperformance805.com), using WordPress as a CMS. I enabled the option to use a static page as the home page, and created that page as /home. Well, now the issue that exists is that Google is indexing both www.tntperformance805.com, and www.tntperformance805.com/home/. I've already setup a 301 redirect, pointing /home/ to the main domain, and even have rel=canonical set up automatically, pointing every page to the www version of that particular page. However, Google Webmaster Tools is still reporting the pages as having duplicate page titles and descriptions. I've even had the page removed from Google's cache and index. I'm assuming Google is not considering the 301 redirect, even though it's setup properly. Should I add rel="canonical" href="http://www.tntperformance805.com" /> to the body of the /home/ post, to ensure that it is giving credit to the main domain? I am assuming the page is only redirecting to , as that's the www version, but I thought the 301 redirect would enforce that the search engines should give all credit to the main domain. Thanks in advance for the help everyone. I look forward to some insightful feedback. Best Regards, Matt Dimock

ECommerce syndication & duplicate content
We have an eCommerce website with original software products. We want to syndicate our content to partner and affiliate websites, but are worried about the effect of duplicate content all over the web. Note that this is a relatively high profile project, where thousands of sites will be listing hundreds of our products, with the exact same name, description, tags, etc. We read the wonderful and relevant post by Kate Morris on this topic (here: http://mz.cm/nXho02) and we realize the duplicate content is never the best option. Some concrete questions we're trying to figure out: 1. Are we risking penalties of any sort? 2. We can potentially get tens of thousands of links from this concept, all with duplicate content around them, but from PR3-6 sites, some with lots of authority. What will affect our site more - the quantity of mediocre links (good) or the duplicate content around them (bad)? 3. Should we sacrifice SEO for a good business idea?
