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.

Does using Yoast variables for meta content overwrite any pages that already have custom meta content?
The question is about the Yoast plugin for WP sites. Let's say I have a site with 200 pages and custom meta descriptions / title tags already in place for the top 30 pages. If I use the Yoast variable tool to complete meta content for the remaining pages (and make my Moz issue tracker look happier), will that only affect the pages without custom meta descriptions or will it overwrite even the pages with the custom meta content that I want? In this situation, I do want to keep the meta content that is already in place on select pages. Thanks! Zack

Duplicate Content - Bulk analysis tool?
Hi I wondered if there's a tool to analyse duplicate content - within your own site or on external sites, but that you can upload the URL's you want to check in bulk? I used Copyscape a while ago, but don't remember this having a bulk feature? Thank you!

Duplicate content penalty
when moz crawls my site they say I have 2x the pages that I really have & they say I am being penalized for duplicate content. I know years ago I had my old domain resolve over to my new domain. Its the only thing that makes sense as to the duplicate content but would search engines really penalize me for that? It is technically only on 1 site. My business took a significant sales hit starting early July 2013, I know google did and algorithm update that did have SEO aspects. I need to resolve the problem so I can stay in business

Duplicate Content on Event Pages
My client has a pretty popular service of event listings and, in hope of gathering more events, they opened up the platform to allow users to add events. This works really well for them and they are able to garner a lot more events this way. The major problem I'm finding is that many event coordinators and site owners will take the copy from their website and copy and paste it, duplicating a lot of the content. We have editor picks that contain a lot of unique content but the duplicate content scares me. It hasn't hurt our page ranking (we have a page ranking of 7) but I'm wondering if this is something that we should address. We don't have the manpower to eliminate all the duplication but if we cut down the duplication would we experience a significant advantage over people posting the same event?

Page content length...does it matter?
As I begin developing my website's content, does it matter how long or short the actual text found in the is? I heard someone say before "a minimum of 250 words", but is that true? If so, what is the maximum length I should use?

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!

Would it be bad to change the canonical URL to the most recent page that has duplicate content, or should we just 301 redirect to the new page?
Is it bad to change the canonical URL in the tag, meaning does it lose it's stats? If we add a new page that may have duplicate content, but we want that page to be indexed over the older pages, should we just change the canonical page or redirect from the original canonical page? Thanks so much! -Amy
