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.

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.

What are partial urls and why this is causing a sitemap error?
Hi mozzers, I have a client that recorded 7 errors when generating Xml sitemap. One of the errors appear to be coming from partial urls and apparently I would need to exclude them from sitemap. What are they exactly and why would they cause an error in the sitemap. Thanks!

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.

Url structure for multiple search filters applied to products
We have a product catalog with several hundred similar products. Our list of products allows you apply filters to hone your search, so that in fact there are over 150,000 different individual searches you could come up with on this page. Some of these searches are relevant to our SEO strategy, but most are not. Right now (for the most part) we save the state of each search with the fragment of the URL, or in other words in a way that isn't indexed by the search engines. The URL (without hashes) ranks very well in Google for our one main keyword. At the moment, Google doesn't recognize the variety of content possible on this page. An example is: http://www.example.com/main-keyword.html#style=vintage&color=blue&season=spring We're moving towards a more indexable URL structure and one that could potentially save the state of all 150,000 searches in a way that Google could read. An example would be: http://www.example.com/main-keyword/vintage/blue/spring/ I worry, though, that giving so many options in our URL will confuse Google and make a lot of duplicate content. After all, we only have a few hundred products and inevitably many of the searches will look pretty similar. Also, I worry about losing ground on the main http://www.example.com/main-keyword.html page, when it's ranking so well at the moment. So I guess the questions are: Is there such a think as having URLs be too specific? Should we noindex or set rel=canonical on the pages whose keywords are nested too deep? Will our main keyword's page suffer when it has to share all the inbound links with these other, more specific searches?

Canonical URLs and Sitemaps
We are using canonical link tags for product pages in a scenario where the URLs on the site contain category names, and the canonical URL points to a URL which does not contain the category names. So, the product page on the site is like www.example.com/clothes/skirts/skater-skirt-12345, and also like www.example.com/sale/clearance/skater-skirt-12345 in another category. And on both of these pages, the canonical link tag references a 3rd URL like www.example.com/skater-skirt-12345. This 3rd URL, used in the canonical link tag is a valid page, and displays the same content as the other two versions, but there are no actual links to this generic version anywhere on the site (nor external). Questions: 1. Does the generic URL referenced in the canonical link also need to be included as on-page links somewhere in the crawled navigation of the site, or is it okay to be just a valid URL not linked anywhere except for the canonical tags? 2. In our sitemap, is it okay to reference the non-canonical URLs, or does the sitemap have to reference only the canonical URL? In our case, the sitemap points to yet a 3rd variation of the URL, like www.example.com/product.jsp?productID=12345. This page retrieves the same content as the others, and includes a canonical link tag back to www.example.com/skater-skirt-12345. Is this a valid approach, or should we revise the sitemap to point to either the category-specific links or the canonical links?

Url with hypen or.co?
Given a choice, for your #1 keyword, would you pick a .com with one or two hypens? (chicago-real-estate.com) or a .co with the full name as the url (chicagorealestate.co)? Is there an accepted best practice regarding hypenated urls and/or decent results regarding the effectiveness of the.co? Thank you in advance!

URL Length or Exact Breadcrumb Navigation URL? What's More Important
Basically my question is as follows, what's better: www.romancingdiamonds.com/gemstone-rings/amethyst-rings/purple-amethyst-ring-14k-white-gold (this would fully match the breadcrumbs). or www.romancingdiamonds.com/amethyst-rings/purple-amethyst-ring-14k-white-gold (cutting out the first level folder to keep the url shorter and the important keywords are closer to the root domain). In this question http://www.seomoz.org/qa/discuss/37982/url-length-vs-url-keywords I was consulted to drop a folder in my url because it may be to long. That's why I'm hesitant to keep the bradcrumb structure the same. To the best of your knowldege do you think it's best to drop a folder in the URL to keep it shorter and sweeter, or to have a longer URL and have it match the breadcrumb structure? Please advise, Shawn
