Duplicate Content - Just how killer is it?
-
Yesterday I received my ranking report and was extremely disappointed that my high-priority pages dropped in rank for a second week in a row for my targeted keywords. This is after running them through the gradecard and getting As for each of them on the keywords I wanted.
I looked at my google webmaster tools and saw new duplicate content pages listed, which were the ones I had just modified to get my keyword targeting better. In my hastiness to work on getting the keyword usage up, I neglected to prevent these descriptions from coming up when viewing the page with filter parameters, sort parameters and page parameters... so google saw these descriptions as duplicate content (since myurl.html and myurl.html?filter=blah are seen as different).
So my question: is this the likely culprit for some pretty drastic hits to ranking? I've fixed this now, but are there any ways to prevent this in the future? (I know _of _canonical tags, but have never used them, and am not sure if this applies in this situation)
Thanks!
EDIT: One thing I forgot to ask as well: has anyone inflicted this upon themselves? And how long did it take you to recover?

The canonical tags are definitely applicable to this situation once Google goes everything again and sorts it all out with the new tags.

Just a note. Besides the canonical fix, you can also go into google webmasters and instruct them if you want them to show the www version or non www version. This can fix the url side of duplicate content. This doesn't fix the whole problem but is a good feature to utilize. I hope this helps.

Duplicate content can pack a double punch since not only does it potentially look like spam to Google but it also divides up the value of the pages between the multiple sources. Best case is to eliminate duplicate content, but often the easier fix--especially when parameters are involved--is to use canonical.
Google doesn't always seem to respect the canonical tag, but it should help mitigate duplicate content errors that can definitely drag down the rankings.

Https Duplicate Content
My previous host was using shared SSL, and my site was also working with https which I didn’t notice previously. Now I am moved to a new server, where I don’t have any SSL and my websites are not working with https version. Problem is that I have found Google have indexed one of my blog http://www.codefear.com with https version too. My blog traffic is continuously dropping I think due to these duplicate content. Now there are two results one with http version and another with https version. I searched over the internet and found 3 possible solutions. 1 No-Index https version

How different does content need to be to avoid a duplicate content penalty?
I'm implementing landing pages that are optimized for specific keywords. Some of them are substantially the same as another page (perhaps 10-15 words different). Are the landing pages likely to be identified by search engines as duplicate content? How different do two pages need to be to avoid the duplicate penalty?

Duplicate content issue with trailing / ?
Hi ,I did a SEOmoz Crawl Test and found most pages show twice, for example: A: www.website.com/index.php/dog/walk B: www.website.com/index.php/dog/walk/ I've checked Google Analytics and 90% of organic search traffic arrives on the URLs with the trailing slash (B). Question 1: Can I assume I've a duplicate content problem? Question 2: Is it best to do 301 redirects from the 'non trailing slash' pages to the 'trailing slash pages'? Question 3: For some reason every web page has a '/index.php' in it (see A&B) above. No idea why. Should it be a SEO concern? Kind regards and thank you in advance Nigel

Duplicate page content issue needs resolution.
After my last "crawl" report, I received a warning about "duplicate page content". One page was: http://anycompany.com and the other was: http://anycompany.com/home.html How do I correct this so these pages aren't competing with each other or is this a problem?

Duplicate content
I am getting flagged for duplicate content, SEOmoz is flagging the following as duplicate: www.adgenerator.co.uk/ www.adgenerator.co.uk/index.asp These are obviously meant to be the same path so what measures do I take to let the SE's know that these are to be considered the same page. I have used the canonical meta tag on the Index.asp page.
