Duplicate Titles caused by multiple variations of same URL
-
Hi. Can you please advise how I can overcome this issue. Moz.com crawle is indicating I have 100's of Duplicate Title tag errors. However this is caused because many URL's have been indexed multiple times in Google. For example.
www.abc.com
www.abc.com/?b=123What can I do to stop this issue being reported as duplictae Titles, as well as content?
I was thinking maybe I can use Robots.txt to block various query string parameters. I'm Open to ideas and examples.

Depending on how you implement the canonicals, you should see a decrease in your duplicate errors, which will be replaced by canonical notices. Ideally, there won't be anything to ignore.

Thank you for your response.
Does this mean for each main page I have i.e.
etc,
if I put a Rel="canonical", I can then ignore messages of duplicate content for URL's reported such as
abc.com/page1 (put a rel="canonical" on this page)
abc.com/page2 (put a rel="canonical" on this page)
abc.com/index.html (put a rel="canonical" on this page)
etc,
?

*Edit: Miki beat me to it, but here's a little more explanation.

The first thing to note here is that Google's indexing doesn't actually have any effect on your Moz crawl report. All of the data you see there comes from our very own rogerbot, which crawls similarly to googlebot.
Though Google's crawler has a wide variety of ways to locate and index content, rogerbot can only crawl links on your site. If your crawl report is picking up each of these URLs, then there must be links pointing to those URLs somewhere on your site. The danger here is that Google and the other search engines will pick up those variants and not be able to determine which of them is the "real" one. That could lead to a) Google listing a URL you'd rather it didn't, or b) Google not understanding how to list your site at all.
A few of these have pretty simple fixes—index.html should be 301 redirected to your root domain, for example. Rel="canonical" is very applicable here, too. Here are a couple resources you may want to check out:

I would redirect all variations to www.abc.com as well as REL=Canonical back to www.abc.com. This should solve you issues.

Will disallowing URL's in the robots.txt file stop those URL's being indexed by Google
I found a lot of duplicate title tags showing in Google Webmaster Tools. When I visited the URL's that these duplicates belonged to, I found that they were just images from a gallery that we didn't particularly want Google to index. There is no benefit to the end user in these image pages being indexed in Google. Our developer has told us that these urls are created by a module and are not "real" pages in the CMS. They would like to add the following to our robots.txt file Disallow: /catalog/product/gallery/ QUESTION: If the these pages are already indexed by Google, will this adjustment to the robots.txt file help to remove the pages from the index? We don't want these pages to be found.

Attack of the dummy urls -- what to do?
It occurs to me that a malicious program could set up thousands of links to dummy pages on a website: www.mysite.com/dynamicpage/dummy123 www.mysite.com/dynamicpage/dummy456 etc.. How is this normally handled? Does a developer have to look at all the parameters to see if they are valid and if not, automatically create a 301 redirect or 404 not found? This requires a table lookup of acceptable url parameters for all new visitors. I was thinking that bad url names would be rare so it would be ok to just stop the program with a message, until I realized someone could intentionally set up links to non existent pages on a site.

Is Google indexing Mp3 audio and MIDI music files? Can that cause any duplicate problems?
Hello, I own virtualsheetmusic.com website and we have several thousands of media files (Mp3 and MIDI files) that potentially Google can index. If that's the case, I am wondering if that could cause any "duplicate" issues of some sort since many of such media files have exact file names or same meta information inside. Any thoughts about this issue are very welcome! Thank you in advance to anyone.

Overly-Dynamic URL
Hi, We have over 5000 pages showing under Overly-Dynamic URL error Our ecommerce site uses Ajax and we have several different filters like, Size, Color, Brand and we therefor have many different urls like, http://www.dellamoda.com/Designer-Pumps.html?sort=price&sort_direction=1&use_selected_filter=Y http://www.dellamoda.com/Designer-Accessories.html?sort=title&use_selected_filter=Y&view=all http://www.dellamoda.com/designer-handbags.html?use_selected_filter=Y&option=manufacturer%3A&page3 Could we use the robots.txt file to disallow these from showing as duplicate content? and do we need to put the whole url in there? like: Disallow: /*?sort=price&sort_direction=1&use_selected_filter=Y if not how far into the url should be disallowed? So far we have added the following to our robots,txt Disallow: /?sort=title Disallow: /?use_selected_filter=Y Disallow: /?sort=price Disallow: /?clearall=Y Just not sure if they are correct. Any help would be greatly appreciated. Thank you,Kami

Duplicate page titles Wordpress SEO/Yoast
Hi I have a Wordpress site using the Wordpress SEO plugin by Yoast. Everything appears to be fine except that on 1 Feb SEOMoz crawl suddenly picked up a bunch of errors. The errors are duplicate page titles, and these exist only for the mysite.com/page/X pages. I can't find any setting in Yoast that looks wrong or tells me how to fix this. The pages are also dynamically canonicalizing to themselves - not sure if this makes any difference although I don't know how this is happening. Does anyone know how to fix this duplicate title error? Alex
