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?

A penalty is something google will have to manually remove and you will be able to see that in webmaster tools. A devaluation is when you are adjusted by the algorithm and lowered as a result because each thing that google does not like acts as points against you but you can quickly change and see your results return. Does that make sense?
-
We decided that it was worth a large investment as we would own the content ourselves and not worry in the future about anyone claiming ownership to the content as google gets stricter. So we re wrote half a million words!
-
Also could you fully explain the difference between devaluation and a penalty?
-
Do you mind if I ask how much of the content you re-wrote? My main fear is the amount of work that this would take since a lot of content goes up on the site daily. If the content is re-written did you do the same amount of content or did you re-write your office space listings with less content?

This is a Panda issue.
Google has said many times with affiliate sites that use the same content that if they do a better job than the original site it will rank them. So its not all bad when you look at it from that point of view.
However, Google loves unique content and will do its best to rank sites first that have the unique content. I have a business in the office space industry and a few years back we used to aggregate office apace listings which were shared amongst 30+ sites. The display of these listings would be different for many searches but the content was the same as all the other sites. This slowly put us in a PANDA DEVALUATION (there is no panda penalty).
After re-writing them with our clients we saw a significant change once the content had be re-crawled.
So it can have a great effect. If Google starts to see that large parts of your site are duplicate content it will start to question the authority you have in your industry.
Could you offer and incentive to your customers to write something unique? And also maybe inform your users not to copy and paste their own content on your site as this could affect them negatively in Google?
If you are an authority could you tell users that if you want to be listed it must be unique? Or if its a paid service have an ad on service for a few bucks where you write a professional description? Might become a nice additional income?

Duplicate content in sidebar
Hi guys. So I have a few sentences (about 50 words) of duplicate content across all pages of my website (this is a repeatable text in sidebar). Each page of my website contains about 1300 words (unique content) in total, and 50 words of duplicate content in sidebar. Does having a duplicate content of this length in sidebar affect the rankings of my website in any way? Thank you so much for your replies.

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!

Thoughts on archiving content on an event site?
I have a few sites that are used exclusively to promote live events (ex. tradeshows, conference, etc). In most cases these sites content fewer than 100 pages and include information for the upcoming event with links to register. Some time after the event has ended, we would redesign the site and start promoting next years event...essentially starting over with a new site (same domain). We understand the value that many of these past event pages have for users who are looking for info from the past event and we're looking for advice on how best to archive this content to preserve for SEO. We tend to use concise urls for pages on these sites. Ex. www.event.com/agenda or www.event.com/speakers. What are your thoughts on archiving the content from these pages so we can reuse the url with content for the new event? My first thought is to put these pages into an archive, like www.event.com/2015/speakers. Is there a better way to do this to preserve the SEO value of this content?

Duplicate page titles and hreflang tags
Moz is flagging a lot of pages on our site which have duplicate page titles. 99% of these are international pages which hreflang tags in the sitemap. Do I need to worry about this? I assumed that it wasn't an issue given the use of hreflang. And if that's the case, why is Moz flagging them as an issue? Thanks.

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

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?
