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.

Upper and lower case URLS coming up as duplicate content
Hey guys and gals, I'm having a frustrating time with an issue. Our site has around 10 pages that are coming up as duplicate content/ duplicate title. I'm not sure what I can do to fix this. I was going to attempt to 301 direct the upper case to lower but I'm worried how this will affect our SEO. can anyone offer some insight on what I should be doing? Update: What I'm trying to figure out is what I should do for our URL's. For example, when I run an audit I'm getting two different pages: aaa.com/BusinessAgreement.com and also aaa.com/businessagreement.com. We don't have two pages but for some reason, Google thinks we do.

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.

Removing duplicate content
Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

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.

Does Google Read URL's if they include a # tag? Re: SEO Value of Clean Url's
An ECWID rep stated in regards to an inquiry about how the ECWID url's are not customizable, that "an important thing is that it doesn't matter what these URLs look like, because search engines don't read anything after that # in URLs. " Example http://www.runningboards4less.com/general-motors#!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 Basically all of this: #!/Classic-Pro-Series-Extruded-2/p/28043025/category=6593891 That is a snippet out of a conversation where ECWID said that dirty urls don't matter beyond a hashtag... Is that true? I haven't found any rule that Google or other search engines (Google is really the most important) don't index, read, or place value on the part of the url after a # tag.

Problems with ecommerce filters causing duplicate content.
We have an ecommerce website with 700 pages. Due to the implementation of filters, we are seeing upto 11,000 pages being indexed where the filter tag is apphended to the URL. This is causing duplicate content issues across the site. We tried adding "nofollow" to all the filters, we have also tried adding canonical tags, which it seems are being ignored. So how can we fix this? We are now toying with 2 other ideas to fix this issue; adding "no index" to all filtered pages making the filters uncrawble using javascript Has anyone else encountered this issue? If so what did you do to combat this and was it successful?
