Percentage of duplicate content allowable

Can you have ANY duplicate content on a page or will the page get penalized by Google?
For example if you used a paragraph of Wikipedia content for a definition/description of a medical term, but wrapped it in unique content is that OK or will that land you in the Google / Panda doghouse?
If some level of duplicate content is allowable, is there a general rule of thumb ratio unique-to-duplicate content?
thanks!

I dont believe you have aproblem if you havea bit of duplicate content, google does not penilize you for duplicate content, it just dosent award you points for it.

That sounds like something Google will hate by default. Your problem there is page quantity to quality and uniqueness ratio.

It's quite difficult to provide the exact data as Google algorithm is Google's hidden treasure. Better to keep yourself safe by creating completely unique content, Referring to your example of Wikipedia definition, you can add something like " ACCORDING TO WIKIPEDIA ..... " while copying definition or adding reference links while copying any content from other sources.
Remember that Google is not only giving importance to unique content but it should be of high quality. That means the article should be innovative like a complete new thing & well researched, so it mustn't be of 200 or less words. So Google will compare the quality of the whole article with the copied content & then it'll decide whether it's a duplicate content article or not.

We recently launched a large 3500 page website that auto generates a sentence after we plug in statistical data in our database.
So the only unique content is a single sentence?
Within that sentence many of the words would need to be common as well. Consider a simple site that offered the population for any given location. "The population of [California] is [13 million] people."
In the above example only 3 words are unique. Maybe your pages are a bit more elaborate but it seems to me those pages are simply not indexable. What you can do is index the main page where users can enter the location they wish to learn about, but not each possible result (i.e. California).
Either add significantly more content, or only index the main page.

We recently launched a large 3500 page website that auto generates a sentence after we plug in statistical data in our database. All pages are relevant to users and provide more value than other results in serps, but i think a penalty is in place that the farmer update may have detected with a sort of auto-penalty against us.
I sent in a reconsideration request last week, the whole project is on hold until we get a response. I'm expecting a generic answer from them.
We are debating on either writing more unique content for every page or entering in more statistical data to run some cool correlations. The statistical data would be 3x more beneficial to the user I feel, but unique content is what Google seeks and a safer bet just to get us indexed properly.

We're currently observing a crumbling empire of websites with auto-generated content. Google is somehow able to understand how substantial your content is and devalue the page and even the whole site if it does not meet their criteria. This is especially damaging for sites who have say 10% of great unique content and 90% of their pages are generated via tagging, browsable search and variable driven paragraphs of text.
Having citations is perfectly normal but I would include reference section just in case.

You can have some duplicate content in the manner you mentioned above. It is a natural and expected part of the internet that existing sources of information will be utilized.
There is not any magic number which says "30% duplication is ok, but 31% is not". Google's algorithms are private and constantly changing. Use good sense to guide you as to whether your page is unique and offers value to users.

Do quotation marks in content effect SERPs?
Some of my art object products have words and phrases engraved on them. The words relate to the images on the product. In the product descriptions, I have been putting quotes around the entire list. Would I get better long tail results if I didn't use the quotation marks? In other words, do the quotes make everything between them an exact match phrase? For example:

Current product description:
The worlds around the edge of the lazy susan read, "Explore nature. Dream big. Take time to smell the flowers. Enjoy the changing seasons. Seize the day. Relish the night. Live life to the fullest." Thank you for helping with this, all comments on how to present this kind of content are welcomed- Stephen kSOjt5a0 -
Duplicate Content when Using "visibility classes" in responsive design layouts? - a SEO-Problem?
I have text in the right column of my responsive layout which will show up below the the principal content on small devices. To do this I use visibility classes for DIVs. So I have a DIV with with a unique style text that is visible only on large screen sizes. I copied the same text into another div which shows only up only on small devices while the other div will be hidden in this moment. Technically I have the same text twice on my page. So this might be duplicate content detected as SPAM? I'm concerned because hidden text on page via expand-collapsable textblocks will be read by bots and in my case they will detect it twice?Does anybody have experiences on this issue?bestHolger

Plagiarism or duplicate checker tool?
Do you know a plagiarism or duplicate checker tool where I can receive an email alert if someone copies my content? I know there's a tool like this (similar to http://www.tynt.com/ though people can still remove the link from the original source) but I forgot the name or site. It's like a source code that you must insert in each of your webpage. Thanks in advanced!

Page content length...does it matter?

What's the best practice for handling duplicate content of product descriptions with a drop-shipper?
We write our own product descriptions for merchandise we sell on our website. However, we also work with drop-shippers, and some of them simply take our content and post it on their site (same photos, exact ad copy, etc...). I'm concerned that we'll loose the value of our content because Google will consider it duplicated. We don't want the value of our content undermined... What's the best practice for avoiding any problems with Google? Thanks, Adam

Is content aggregation good SEO?
I didn't see this topic specifically addressed here: what's the current thinking on using content aggregation for SEO purposes? I'll use flavors.me as an example. Flavors.me lets you set up a domain that pulls in content from a variety of services (Twitter, YouTube, Flickr, RSS, etc.). There's also a limited ability to publish unique content as well. So let's say that we've got MyDomain.com set up, and most of the content is being drawn in from other services. So there's blog posts from WordPress.com, videos from YouTube, a photo gallery from Flickr, etc. How would Google look at this scenario? Is MyDomain.com simply scraped content from the other (more authoritative) sources? Is the aggregated content perceived to "belong" to MyDomain.com or not? And most importantly, if you're aggregating a lot of content related to Topic X, will this content aggregation help MyDomain.com rank for Topic X? Looking forward to the community's thoughts. Thanks!

Avoiding "Duplicate Page Title" and "Duplicate Page Content" - Best Practices?
We have a website with a searchable database of recipes. You can search the database using an online form with dropdown options for: Course (starter, main, salad, etc)
On-Page Optimization | | smaavie
Cooking Method (fry, bake, boil, steam, etc)
Preparation Time (Under 30 min, 30min to 1 hour, Over 1 hour) Here are some examples of how URLs may look when searching for a recipe: find-a-recipe.php?course=starter
find-a-recipe.php?course=main&preperation-time=30min+to+1+hour
find-a-recipe.php?cooking-method=fry&preperation-time=over+1+hour There is also pagination of search results, so the URL could also have the variable "start", e.g. find-a-recipe.php?course=salad&start=30 There can be any combination of these variables, meaning there are hundreds of possible search results URL variations. This all works well on the site, however it gives multiple "Duplicate Page Title" and "Duplicate Page Content" errors when crawled by SEOmoz. I've seached online and found several possible solutions for this, such as: Setting canonical tag Adding these URL variables to Google Webmasters to tell Google to ignore them Change the Title tag in the head dynamically based on what URL variables are present However I am not sure which of these would be best. As far as I can tell the canonical tag should be used when you have the same page available at two seperate URLs, but this isn't the case here as the search results are always different. Adding these URL variables to Google webmasters won't fix the problem in other search engines, and will presumably continue to get these errors in our SEOmoz crawl reports. Changing the title tag each time can lead to very long title tags, and it doesn't address the problem of duplicate page content. I had hoped there would be a standard solution for problems like this, as I imagine others will have come across this before, but I cannot find the ideal solution. Any help would be much appreciated.
