Penalty for duplicate content on the same website?

Is it possible to get a penalty for duplicate content on the same website?
I have a old custom-built site with a large number of filters that are pre-generated for speed. Basically the only difference is the meta title and H1 tag, with a few text differences here and there.
Obviously I could no-follow all the filter links but it would take an enormous amount of work.
The site is performing well in the search.
I'm trying to decide whether if there is a risk of a penalty, if not I'm loath to do anything in case it causes other issues.

Your ranking will be decreased. It is better to use canonical URL to avoid duplicate contents in your website.

It wouldn't cause a literal penalty from Google, however, yes, it can hurt your site's rankings.
It sounds like those filters use URL parameters? If so it's possible for all parameterized URLs to be controlled or use canonical tags to indicate duplicate content.
What types of filters are these? EG what is changing on the page when you select the filters? Is this like an ecommerce category experience where you're filtering product listings?

Hi seoman10,
there is no penalty for duplicated content but rankings can be impacted negatively because of the duplicated content and your web may have a worst performance on Google.
This is because Google will waste many time searching in all your similar content to decide which page to show in the search results, wasting also your "crawl budget", and probably will also divide the authority between more than one of the similar pages, losing authority in this process.
Also, Google may choose to show in the search results a filter version of the page that is not your preferred one.
I recommend you to use canonicals to solve this problem, pointing all the filter versions of the page with canonical to the non-filter one.
Hope that helps
Good luck!

Duplicate content across domains?
Does anyone have suggestions for managing duplicate product/solution website content across domains? (specifically parent/child company domains) Is it advisable to do this? Will it hurt either domain? Any best practices when going down this path?

Semi-duplicate content yet authoritative site
So I have 5 real estate sites. One of those sites is of course the original, and it has more/better content on most of the pages than the other sites. I used to be top ranked for all of the subdivsion names in my town. Then when I did the next 2-4 sites, I had some sites doing better than others for certain keywords, and then I have 3 of those sites that are basically the same URL structures (besides the actual domain) and they aren't getting fed very many visits. I have a couple of agents that work with me that I loaned my sites to to see if that would help since it would be a different name. My same youtube video is on each of the respective subdivision pages of my site and theirs. Also, their content is just rewritten content from mine about the same length of content. I have looked over and seen a few of my competitors who only have one site and their URL structures arent good at all, and their content isn't good at all and a good bit of their pages rank higher than my main site which is very frustrating to say the least since they are actually copy cats to my site. I sort of started the precedent of content, mapping the neighborhood, how far that subdivision is from certain landmarks, and then shot a video of each. They have pretty much done the same thing and are now ahead of me. What sort of advice could you give me? Right now, I have two sites that are almost duplicate in terms of a template and same subdivsions although I did change the content the best I could, and that site is still getting pretty good visits. I originally did it to try and dominate the first page of the SERPS and then Penguin and Panda came out and seemed to figure that game out. So now, I would still like to keep all the sites, but I'm assuming that would entail making them all unique, which seems to be tough seeing as though my town has the same subdivisions. Curious as to what the suggestions would be, as I have put a lot of time into these sites. If I post my site will it show up in the SERPS? Thanks in advance

Duplicate Internal Content on E-Commerce Website
Hi, I find my e-commerce pharmacy website is full of little snippets of duplicate content. In particular: -delivery info widget repeated on all the product pages -product category information repeated product pages (e.g. all medicines belonging to a certain category of medicines have identical side effects and I also include a generic snippet of the condition the medicine treats) Do you think it will harm my rankings to do this?

Category Pages For Distributing Authority But Not Creating Duplicate Content
I read this interesting moz guide: http://moz.com/learn/seo/robotstxt, which I think answered my question but I just want to make sure. I take it to mean that if I have category pages with nothing but duplicate content (lists of other pages (h1 title/on-page description and links to same) and that I still want the category pages to distribute their link authority to the individual pages, then I should leave the category pages in the site map and meta noindex them, rather than robots.txt them. Is that correct? Again, don't want the category pages to index or have a duplicate content issue, but do want the category pages to be crawled enough to distribute their link authority to individual pages. Given the scope of the site (thousands of pages and hundreds of categories), I just want to make sure I have that right. Up until my recent efforts on this, some of the category pages have been robot.txt'd out and still in the site map, while others (with different url structure) have been in the sitemap, but not robots.txt'd out. Thanks! Best.. Mike

How to remove duplicate content, which is still indexed, but not linked to anymore?
Dear community A bug in the tool, which we use to create search-engine-friendly URLs (sh404sef) changed our whole URL-structure overnight, and we only noticed after Google already indexed the page. Now, we have a massive duplicate content issue, causing a harsh drop in rankings. Webmaster Tools shows over 1,000 duplicate title tags, so I don't think, Google understands what is going on. <code>Right URL: abc.com/price/sharp-ah-l13-12000-btu.html Wrong URL: abc.com/item/sharp-l-series-ahl13-12000-btu.html (created by mistake)</code> After that, we ... Changed back all URLs to the "Right URLs" Set up a 301-redirect for all "Wrong URLs" a few days later Now, still a massive amount of pages is in the index twice. As we do not link internally to the "Wrong URLs" anymore, I am not sure, if Google will re-crawl them very soon. What can we do to solve this issue and tell Google, that all the "Wrong URLs" now redirect to the "Right URLs"? Best, David

How are they avoiding duplicate content?
One of the largest stores in USA for soccer runs a number of whitelabel sites for major partners such as Fox and ESPN. However, the effect of this is that they are creating duplicate content for their products (and even the overall site structure is very similar). Take a look at: http://www.worldsoccershop.com/23147.html http://www.foxsoccershop.com/23147.html http://www.soccernetstore.com/23147.html You can see that practically everything is the same including: product URL product title product description My question is, why is Google not classing this as duplicate content? Have they coded for it in a certain way or is there something I'm missing which is helping them achieve rankings for all sites?
