Using robots.txt to deal with duplicate content
-
I have 2 sites with duplicate content issues.
One is a wordpress blog.
The other is a store (Pinnacle Cart).
I cannot edit the canonical tag on either site. In this case, should I use robots.txt to eliminate the duplicate content?

It will be any part of the URL that doesn't handle navigation, so look at what you can delete off the URL without breaking the link to the product page.
Take a look at this: http://googlewebmastercentral.blogspot.com/2009/10/new-parameter-handling-tool-helps-with.html
Remember, this will only work with Google!
This is another interesting video from Matt Cutts about removing content from Google: http://googlewebmastercentral.blogspot.com/2008/01/remove-your-content-from-google.html

If the urls look like this...
Would I tell Google to ignore p, mode, parent, or CatalogSetSortBy? Just one of those or all of those?
Thanks!!!

For Wordpress try : http://wordpress.org/extend/plugins/canonical/
also look at Yoast's Wordpress SEO plugin referenced on that page - I love it!
and for the duplicate content caused by the dymanic content on the pinnacle cart you can use the Google Webmasters tool to tell the Google to ignore certain parameters - go to Site configuration - Settings - Parameter handling and add the variables you wish to ignore to this list.

Hi,
The two sites are unrelated to each other so my concern is not duplicate content between the two, there is none.
However, on each of the sites I have the duplicate content issues. I do have admin privileges to both sites.
If there is a Wordpress plug in that would be great. Do you have one that you would recommend?
For my ecommerce site using pinnacle cart, I have duplicates because of the way people can search on the site. For example:
|
http://www.domain.com/accessories/
http://www.domain.com/accessories/?p=catalog&mode=catalog&parent=17&pg=1&CatalogSetSortBy=date
http://www.domain.com/accessories/?p=catalog&mode=catalog&parent=17&pg=1&CatalogSetSortBy=name
http://www.domain.com/accessories/?p=catalog&mode=catalog&parent=17&pg=1&CatalogSetSortBy=price
|
These all show as duplicate content in my webmaster tools reports. I don't have the ability to edit each head tag of pages in order to add a canonical link on this site.

What are your intentions here? Do you intend to leave both sites running? Can you give us more information on the sites? Are they aged domains, is one/any/both of them currently attracting any inbound links, are they ranking? What is the purpose of the duplicate content?
Are you looking to redirect traffic from one of the sites to the other using 301 redirect?
Or do you want both sites visible - using the Canonical link tag?
(I am concerned that you say you 'cannot edit the tag'? Do you not have full Admin access to either site?
There are dedicated Canonical management plugins for Wordpress (if you have access to the wp-admin area)
You are going to need some admin priviledges to make any alterations to the site so that you can correct this.
Let us know a bit more please!

Duplicate Content/Similar Pages
Hello, I'm working on our site and I'm coming into an issue with the duplicate content. Our company manufactures heavy-duty mobile lifts. We have two main lifts. They are the same, except for capacity. We want to keep the format similar and the owner of the company wants each lift to have its own dedicated page. Obviously, since the layout is the same and content is similar I'm getting the duplicate content issue. We also have a section of our accessories and a section of our parts. Each of these sections have individual pages for the accessory/part. Again, the pages are laid out in a similar fashion to keep the cohesiveness, and the content is different, however similar. Meaning different terminology, part numbers, stock numbers, etc., but the overall wording is similar. What can I do to combat these issues? I think our ratings are dropping due to the duplicate content.

Duplicate content : domain alias issue
Hello there ! Let's say my client has 2 webshops (that exists since long time, so many backlinks & good authority on both) : individuals.nl : for individuals (has 200 backlinks, let's say) pros.nl : exact same products, exact same content, but with a different branding intended to professionnals (has 100 backlinks, let's say) So, both websites are 99% identical and it has to remain like that !!! Obviously, this creates duplicate content issues. Goal : I want "individuals.nl" to get all ranking value (while "pros.nl" should remain accessible through direct access & appear on it's own brand queries). Solution ? Implement canonical tags on "pros**.nl**" that goes to "individuals.nl". That way, "individuals.nl" will get all ranking value, while "pros.nl" will still be reachable through direct access. However, "individuals.nl" will then replace "pros.nl" from SERP in the long-term. The only thing I want is to keep "pros.nl" visible for its own brand queries -> it won't be possible through organic search result, so, I'm just gonna buy those "pros" queries through paid search ! Put links on all pages of pros.nl to individuals.nl (but not the other way around), so that "pros.nl" will pass some ranking value to "individuals.nl" (but only a small part of the ranking value -> ideally, I would like to pass all link value to this domain). Could someone advise me ??? (I know it sound a bit complicated... but I don't have much choice ^^)

Tired of finding solution for duplicate contents.
Just my site was scanned by seomoz and seen lots of duplicate content and titles found. Well I am tired of finding solutions of duplicate content for a shopping site product category page. You can see the screenshot below. http://i.imgur.com/TXPretv.png You can see below in every link its showing "items_per_page=64, 128 etc.". This happened in every category in which I was created. I am already using Canonical add-on to avoid this problem but still it's there. You can check my domain here - http://www.plugnbuy.com/computer-software/pc-security/antivirus-internet-security/ and see if the add-on working correct. I recently submitted my sitemap to GWT, so that's why it's not showing me any report regarding duplicate issues. Please help ME

SEOMOZ and non-duplicate duplicate content
Hi all, Looking through the lovely SEOMOZ report, by far its biggest complaint is that of perceived duplicate content. Its hard to avoid given the nature of eCommerce sites that oestensibly list products in a consistent framework. Most advice about duplicate content is about canonicalisation, but thats not really relevant when you have two different products being perceived as the same. Thing is, I might have ignored it but google ignores about 40% of our site map for I suspect the same reason. Basically I dont want us to appear "Spammy". Actually we do go to a lot of time to photograph and put a little flavour text for each product (in progress). I guess my question is, that given over 700 products, why 300ish of them would be considered duplicates and the remaning not? Here is a URL and one of its "duplicates" according to the SEOMOZ report: http://www.1010direct.com/DGV-DD1165-970-53/details.aspx

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1

http://www.discoverafrica.com/js/jquery.cookie.js?v=1.1
http://www.discoverafrica.com/js/global.js?v=1.2
http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0
