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.

How to fix duplicate content for homepage and index.html
Hello, I know this probably gets asked quite a lot but I haven't found a recent post about this in 2018 on Moz Q&A, so I thought I would check in and see what the best route/solution for this issue might be. I'm always really worried about making any (potentially bad/wrong) changes to the site, as it's my livelihood, so I'm hoping someone can point me in the right direction. Moz, SEMRush and several other SEO tools are all reporting that I have duplicate content for my homepage and index.html (same identical page). According to Moz, my homepage (without index.html) has PA 29 and index.html has PA 15. They are both showing Status 200. I read that you can either do a 301 redirect or add rel=canonical I currently have a 301 setup for my http to https page and don't have any rel=canonical added to the site/page. What is the best and safest way to get rid of duplicate content and merge the my non index and index.html homepages together these days? I read that both 301 and canonical pass on link juice but I don't know what the best route for me is given what I said above. Thank you for reading, any input is greatly appreciated!

Duplicate content with tagging and categories
Hello, Moz is showing that a site has duplicate content - which appears to be because of tags and categories. It is a relatively new site, with only a few blog publications so far. This means that the same articles are displayed under a number of different tags and categories... Is this something I should worry about, or just wait until I have more content? The 'tag' and 'category' pages are not really pages I would expect or aim for anyone to find in google results anyway. Would be glad to here any advice / opinions on this Thanks!

Duplicate page titles and Content in Woocommerce
Hi Guys, I'm new to Moz and really liking it so far!
On-Page Optimization | | jeeyer
I run a eCommerce site on Wordpress + WooCommerce and ofcourse use Yoast for SEO optimalisation I've got a question about my first Crawl report which showed over 600 issues! 😐 I've read that this is something that happens more often (http://a-moz.groupbuyseo.org/blog/setup-wordpress-for-seo-success). Most of them are categorized under:
1. Duplicate Page Titles or;
2. Duplicate Page Content. Duplicate Page Titles:
These are almost only: product category pages and product tags. Is this problem beeing solved by giving them the right SEO SERP? I see that a lot of categories don't have a proper SEO SERP set up in yoast! Do I need to add this to clear this issue, or do I need to change the actual Title? And how about the Product tags? Another point (bit more off-topic) I've read here: http://a-moz.groupbuyseo.org/community/q/yoast-seo-plugin-to-index-or-not-to-index-categories that it's advised to noindex/follow Categories and Tags but isn't that a wierd idea to do for a eCommerce site?! Duplicate Page Content:
Same goes here almost only Product Categories and product tags that are displayed as duplicate Page content! When I check the results I can click on a blue button for example "+ 17 duplicates" and that shows me (in this case 17 URLS) but they are not related to the fist in any way so not sure where to start here? Thanks for taking the time to help out!

Duplicate Content - Blog Rewriting
I have a client who has requested a rewrite of 250 blog articles for his IT company. The blogs are dispersed on a variety of platforms: his own website's blog, a business innovation website, and an IT website. He wants to have each article optimised with keyword phrases and then posted onto his new website thrice weekly. All of this is in an effort to attract some potential customers to his new site and also to establish his company as a leader in its field. To what extent would I need to rewrite each article so as to avoid duplicating the content? Would there even be an issue if I did not rewrite the articles and merely optimised them with keywords? Would the articles need to be completely taken by all current publishers? Any advice would be greatly appreciated.

Duplicate Content for Men's and Women's Version of Site
So, we're a service where you can book different hairdressing services from a number of different salons (site being worked on). We're doing both a male and female version of the site on the same domain which users are can select between on the homepage. The differences are largely cosmetic (allowing the designers to be more creative and have a bit of fun and to also have dedicated male grooming landing pages), but I was wondering about duplicate pages. While most of the pages on each version of the site will be unique (i.e. [male service] in [location] vs [female service] in [location] with the female taking precedent when there are duplicates), what should we do about the likes of the "About" page? Pages like this would both be unique in wording but essentially offer the same information and does it make sense to to index two different "About" pages, even if the titles vary? My question is whether, for these duplicate pages, you would set the more popular one as the preferred version canonically, leave them both to be indexed or noindex the lesser version entirely? Hope this makes sense, thanks!

Duplicate Content for Spanish & English Product
Hi There, Our company provides training courses and I am looking to provide the Spanish version of a course that we already provide in English. As it is an e-commerce site, our landing page for the English version gives the full description of the course and all related details. Once the course is purchased, a flash based course launches within a player window and the student begins the course. For the Spanish version of the course, my target customers are English speaking supervisors purchasing the course for their Spanish speaking workers. So the landing page will still be in English (just like the English version of the course) with the same basic description, with the only content differences on that page being the inclusion of the fact that this course is in Spanish and a few details around that. The majority of the content on these two separate landing pages will be exactly the same, as the description for the overall course is the same, just that it's presented in a different language, so it needs to be 2 separate products. My fear is that Google will read this as duplicate content and I will be penalized for it. Is this a possibility or will Google know why I set it up this way and not penalize me? If that is a possibility, how should I go about doing this correctly? Thanks!

Is it better to drip feed content?
Hi All, I've assembled a collection of 5 closely related articles each about 700 words for publishing by linking to them from on one of my pages and would appreciate some advice on the role out of these articles. Backround: My site is a listings based site and a majority of the content is published on my competitors sites too. This is because advertisers are aiming to spread there adverts wide with the hope of generating more responses. The page I'm targeting ranks 11th but I would like to link it to some new articles and guides to beef it up a bit. My main focus is to rank better for the page that links to these articles and as a result I write up an introduction to the article/guide which serves as my unique content. Question: Is it better to drip feed the new articles onto the site or would it be best to get as much unique content on as quickly as possible to increase the ratio of unique content vs. external duplicate content on the page that links to these articles**?** Thank you in advance.
