How to deal with duplicate content when presenting event and sub-events information?
-
Hi,
I'm have a sport event calendar website.
It presents events that may have multiple races.
The event has its own page as well as the races.example :
Event: /event/edinburgh-marathon-festivalRaces:
/race/emf-half-marathon
/race/emf-10-km
/race/edinburgh-marathon
/race/emf-5-kmThe pages may have a lot of information in common (location, date, description) and they all link to each other.
What would be the best practices to avoid having the pages considered duplicate content by Google?Thanks

I like your idea of regrouping on information on one page. My only concern is that the race page has already tabs and that it will lower the number of page vues for the site. As the site revenues come from advertisement ...
Thanks

Thank you for your explanations. I'll give the canonical tag a try. As I have more than 20 000 races, It's impossible for me to create unique descriptions. Most races don't have one.
I'll start by adding the canonical tag on the race pages, linking to the corresponding event page.

Hi Jean-Loup,
I like Gary's idea for canonicalisation as long as you are not too concerned about search traffic that is specifically dedicated to finding information about (for example), the Edinburgh Marathon 5km race. If the 5km race page is canonicalised to the main marathon page and that main marathon page doesn't mention the 5km, your ranking chances are fairly poor.
One other option to consider is presenting this additional information as tabbed content on the main page. Without seeing the actual pages, it's hard to say what this would look like, but essentially you'd have a primary page that lists all the main info about the event, then has tabs in a secondary navigation that use CSS to show content about the 10km, the 5 and the half marathon. You clearly do not have to repeat the general information about the full marathon festival event on each of these tabs, just include information about the specific races. All the HTML about each event is presented in the source code of the one Edinburgh marathon festival page.
This is not considered underhanded or "cloaking" - it's a common way to present information on the same or very similar topic on one URL. As long as the content behind each tab is highly relevant to the original topic (e.g. the marathon and other races) and is not unduly long (don't try to post a 1,000 word blog post in a tab), you will be fine.
This might be a big stylistic undertaking, but it's another option and it also means that just one URL receives the benefit of all the links people point to the event page.

Ok, I hope this is going to be helpful, but I have created two options for you...
- Option 1: Create unique descriptions for each page if you can?
This will take some time and probably a lot of investment. I've experienced this before with clients who always seem to write something very similar for each description, so be very careful with this. - Option 2: OR, Canonicalize all the variations your ' race event' product - what is the best marketable page?
I highly recommend you use the canonical tag to tell search engines that you are fully aware that these 'similar' products are using the same info descriptions, as well as heading etc (if they are). This will help you to keep everything the same for your users, and the bonus is, you do not have to rewrite any new product copy, and... of course this will help avoid getting 'dropped' by search engines. Do this by looking at Google Analytics, what page is working for you, what needs improving? Your analysis will help to create a canonical tag that uses that URL. You should then drop this same tag into allthe products in the set, including the your best page after working out which is working for you (canonical tags can be self referential causing zero problems).
- Option 1: Create unique descriptions for each page if you can?

Duplicate Content in Footers (Not as routine as it seems)
Hello there, I know that content in the footer of sites are safe from duplication penalisation; however, what if the footers where replicated across different subdomains? For instance, the footer was duplicated across: www.example.com blog.example.com blog2.example.com I don't see it as a big issue personally; however, outsourced "specialists" seem to think that this is causing duplication problems and therefore negatively affecting the ranking power of "lesser" subdomains i.e. not the www version, which is by far the strongest subdomain. Would be good to get some insight if anybody has any. Thanks.

Delete or not delete outdated content
Hi there!
On-Page Optimization | | Enrico_Cassinelli
We run a website about a region in Italy, the Langhe area, where we write about wine and food, local culture, and we give touristic informations. The website also sports a nice events calendar: in 4 years we (and our users) loaded more than 5700 events. Now, we're starting to have some troubles managing this database. The database related to events is huge both in file size and number of rows. There are a lot of images that eat up disk space, and also it's becoming difficult to manage all the data in our backend. Also, a lot of users are entering the website by landing on outdated events. I was wondering if it could be a good idea to delete events older than 6 months: the idea was to keep only the most important and yearly recurring events (which we can update each year with fresh information), and trash everything else. This of course means that 404 errors will increase, and also that our content will gettin thinner, but at the same time we'll have a more manageable database, and the content will be more relevant and "clean". What do you think? thank you 🙂 Best0 -

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

Suggestions to avoid duplicate content
Hi, we have about 6500 products, almost all with descriptions. SEOMOZ is showing about 2500 of them with duplicate content. The reason for this is that only one or two words are different for each product. For example, we have 500 award certificates. All are the same size and have the same description. But one is swimming, one baseball, one reading, etc, etc. Apparently the 1 word difference is not enough to differentiate. We have the same issue with our trophies - they are identical, except for figures. Does anyone have any good tips on how to change the content to avoid this issue and to avoid making up content for 2500 items? Thanks! Neil trophycentral.com

Duplicate Content - Site Wide or Internet Wide?
Hello... I am creating a new website and i was wondering how you guys would define duplicate content? If my new site had the same page titles and descriptions as my existing site, would that be duplicate content? Or does duplicate content mean same titles and descriptions in the same site? I'm wondering if i can upload the same database (with page titles and descriptions and alt tags) to my new site or if that would be looked at as duplicate... Thanks

Duplicate content on homepage?
Hi I have just created a new campaign and it states that I have duplicate page content which would affect search rankings. Basically it is counting my site www.mydomain.com and www.mydomain.com/index.php as two seperate pages. How can I make it so that only www.mydomain.com is visible reducing the duplicate content issue? Many Thanks
