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:

http://moz.com/learn/seo/redirection - Best practices article on redirectsI hope that helps!

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.

My url disappeared from Google but Search Console shows indexed. This url has been indexed for more than a year. Please help!
Super weird problem that I can't solve for last 5 hours. One of my urls: https://www.dcacar.com/lax-car-service.html Has been indexed for more than a year and also has an AMP version, few hours ago I realized that it had disappeared from serps. We were ranking on page 1 for several key terms. When I perform a search "site:dcacar.com " the url is no where to be found on all 5 pages. But when I check my Google Console it shows as indexed I requested to index again but nothing changed. All other 50 or so urls are not effected at all, this is the only url that has gone missing can someone solve this mystery for me please. Thanks a lot in advance.

Mass URL changes and redirecting those old URLS to the new. What is SEO Risk and best practices?
Hello good people of the MOZ community, I am looking to do a mass edit of URLS on content pages within our sites. The way these were initially setup was to be unique by having the date in the URL which was a few years ago and can make evergreen content now seem dated. The new URLS would follow a better folder path style naming convention and would be way better URLS overall. Some examples of the **old **URLS would be https://www.inlineskates.com/Buying-Guide-for-Inline-Skates/buying-guide-9-17-2012,default,pg.html

https://www.inlineskates.com/Buying-Guide-for-Aggressive-Skates/buying-guide-7-19-2012,default,pg.html The new URLS would look like this which would be a great improvement https://www.inlineskates.com/Learn/Buying-Guide-for-Inline-Skates,default,pg.html

https://www.inlineskates.com/Learn/Buying-Guide-for-Inline-Hockey-Skates,default,pg.html
https://www.inlineskates.com/Learn/Buying-Guide-for-Aggressive-Skates,default,pg.html My worry is that we do rank fairly well organically for some of the content and don't want to anger the google machine. The way I would be doing the process would be to edit the URLS to the new layout, then do the redirect for them and push live. Is there a great SEO risk to doing this?
Is there a way to do a mass "Fetch as googlebot" to reindex these if I do say 50 a day? I only see the ability to do 1 URL at a time in the webmaster backend.
Is there anything else I am missing? I believe this change would overall be good in the long run but do not want to take a huge hit initially by doing something incorrectly. This would be done on 5- to a couple hundred links across various sites I manage. Thanks in advance,

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?

Multiple 301 redirects for a HTTPS URL. Good or bad?
I'm working on an ecommerce website that has a few snags and issues with it's coding. They're using https, and when you access the website through domain.com, theres a 301 redirect to http://www.domain.com and then this, in turn, redirected to https://www.domain.com. Would this have a deterimental effect or is that considered the best way to do it. Have the website redirect to http and then all http access is redirected to the https URL? Thanks

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
