Penguin Penalty On A Duplicate url
-
Hi
I have noticed a distinct drop in traffic to a page on my web site which occurred around April of last year. Doing some analysis of links pointing to this page, I found that most were sitewide and exact match commercial anchor text.
I think the obvious conclusion from this is I got slapped by Penguin although I didn't receive a warning in Webmaster Tools.
The page in question was ranking highly for our targeted terms and the url was structured like this:
companyname.com/category/index.php
The same page is still ranking for some of those terms, but it is the duplicate url:
The sitewide problem is associated with links going to the index.php page. There aren't too many links pointing to the non index.php page.
My question is this - if we were to 301 redirect index.php to the non php page, would this be detrimental to the rankings we are getting today? ie would we simply redirect the penguin effect to the non php page?
If anybody has come across a similar problem or has any advice, it would be greatly appreciated.
Thanks

Hi Tom
Thanks for your reply and useful help. Your advice about the 301 tallies with what others have said about the matter.
With regard to your indexing question only the ranking url is being indexed.
Thanks again for your help.

Hi Alex
From my own tests and experiments, I'm confident that a 301 redirect passes on the penalty. Usually within 2-3 weeks of redirecting a penalised domain/URL to a fresh one, the new URL lost its rankings. With that in mind, I would not recommend that you do this.
April last year would coincide with the first Penguin refresh, so I think you're right in your penalty diagnosis there. However, when you talk about the duplicate category URL - are both URLs indexed by Google? And are both of them showing the same content?
If so, there is a good chance that you might be under a Panda algorithmic penalty as well. The duplicate content issue would also be effecting the rankings of both URLs and could, potentially, be affecting the entire site.
My recommendation would be to deindex the old, penalised URL by adding to the tag of the page (or blocking it through the robots.txt file. I would then concentrate on ranking the other URL in a safe way. By doing that, you may be able to recover the lost rankings with the new URL, without worrying about Panda or Penguin.
If you have similar duplicate URLs for other categories, I'd highly recommend that you do the same and noindex one version of them. If you're confident no other URL has a penalty attributed to it, you could also 301 redirect one of the URLs to the other.
Hope this helps and apologies if I've covered things here you're familiar with - just wanted to check!

Best to Fix Duplicate Content Issues on Blog If URLs are Set to "No-Index"
Greetings Moz Community: I purchased a SEMrush subscription recently and used it to run a site audit. The audit detected 168 duplicate content issues mostly relating to blog posts tags. I suspect these issues may be due to canonical tags not being set up correctly. My developer claims that since these blog URLs are set to "no-index" these issues do not need to be corrected. My instinct would be to avoid any risk with potential duplicate content. To set up canonicalization correctly. In addition, even if these pages are set to "no-index" they are passing page rank. Further more I don't know why a reputable company like SEMrush would consider these errors if in fact they are not errors. So my question is, do we need to do anything with the error pages if they are already set to "no-index"? Incidentally the site URL is www.nyc-officespace-leader.com. I am attaching a copy of the SEMrush audit. Thanks, Alan BarjWaO SqVXYMy

Penguin Apply To Internal Linking?
Is Penguin focused primarily on backlinks or does it also assess internal linking/anchor text? We've lost about 3,000 visitors a month since the rolling updates were implemented. I'm always careful not to over-react to algo updates but enough time has passed that I think the dust has settled. I try to stay white in all I do but I think if I've over-done anything its the internal linking related products/categories with exact match. My backlink profile also has an over-abundance of affiliate links but that's kind of out of my hands isn't it?

Dealing with Penguin: Changing URL instead of removing links
I have some links pointing to categories from article directories, web directories, and a few blogs. We are talking about 20-30 links in total. They are less than 5% of the links to my site (counting unique domains). I either haven't been able to make contact with webmasters, or they are asking money to remove the links. If I simply rename the URL (for example changing mysite.com/t-shirt.html to mysite.com/tshirts.html), will that resolve any penguin issues? The link will forward to the homepage since that page no longer exists. I really want to avoid using the disavow tool if possible. I appreciate the feedback. If you have actually done this, please share your experience.

http://www.eee.mysite.com
http://www.w.mysite.com The site these links are coming from is a html site. Any ideas whats going on or a way to get rid of these urls? When I visit the strange URLs such as http://www.dwww.mysite.com, it shows the home page of http://www.mysite.com. Is there a way to redirect anything like this back to the home page?0 -
Duplicate content across internation urls
We have a large site with 1,000+ pages of content to launch in the UK. Much of this content is already being used on a .nz url which is going to stay. Do you see this as an issue or do you thin Google will take localised factoring into consideration. We could add a link from the NZ pages to the UK. We cant noindex the pages as this is not an option. Thanks

Overly-Dynamic URLs & Changing URL Structure w Web Redesign
I have a client that has multiple apartment complexes in different states and metro areas. They get good traffic and pretty good conversions but the site needs a lot of updating, including the architecture, to implement SEO standards. Right now they rank for " <brand_name>apartments" on every place but not " <city_name>apartments".</city_name></brand_name> There current architecture displays their URLs like: http://www.<client_apartments>.com/index.php?mainLevelCurrent=communities&communityID=28&secLevelCurrent=overview</client_apartments> http://www.<client_apartments>.com/index.php?mainLevelCurrent=communities&communityID=28&secLevelCurrent=floorplans&floorPlanID=121</client_apartments> I know it is said to never change the URL structure but what about this site? I see this URL structure being bad for SEO, bad for users, and basically forces us to keep the current architecture. They don't have many links built to their community pages so will creating a new URL structure and doing 301 redirects to the new URLs drastically drop rankings? Is this something that we should bite the bullet on now for future rankings, traffic, and a better architecture?
