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.

Duplicate URLs ending with #!
Hi guys, Does anyone know why a site can contain duplicate URLs ending with hastag & exclamation mark e.g. https://site.com.au/#! We are finding a lot of these URLs (as duplicates) and i was wondering what they are from developer standpoint? And do you think it's worth the time and effort adding a rel canonical tag or 301 to these URLs eventhough they're not getting indexed by Google? Cheers, Chris

Trailing Slashes for Magento CMS pages - 2 URLS - Duplicate content
Hello, Can anyone help me find a solution to Fixing and Creating Magento CMS pages to only use one URL and not two URLS? www.domain.com/testpage www.domain.com/testpage/ I found a previous article that applies to my issue, which is using htaccess to redirect request for pages in magento 301 redirect to slash URL from the non-slash URL. I dont understand the syntax fully in htaccess , but I used this code below. This code below fixed the CMS page redirection but caused issues on other pages, like all my categories and products with this error: "This webpage has a redirect loop ERR_TOO_MANY_REDIRECTS" Assuming you're running at domain root. Change to working directory if needed. RewriteBase / # www check If you're running in a subdirectory, then you'll need to add that in to the redirected url (http://www.mydomain.com/subdirectory/$1 RewriteCond %{HTTP_HOST} !^www. [NC]

RewriteRule ^(.*)$ http://www.mydomain.com/$1 [R=301,L] Trailing slash check Don't fix direct file links RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} !(.)/$
RewriteRule ^(.)$ $1/ [L,R=301] Finally, forward everything to your front-controller (index.php) RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

Canonical URL & sitemap URL mismatch
Hi We're running a Magento store which doesn't have too much stock rotation. We've implemented a plugin that will allow us to give products custom canonical URLs (basically including the category slug, which is not possible through vanilla Magento). The sitemap feature doesn't pick up on these URLs, so we're submitting URLs to Google that are available and will serve content, but actually point to a longer URL via a canonical meta tag. The content is available at each URL and is near identical (all apart from the breadcrumbs) All instances of the page point to the same canonical URL We are using the longer URL in our internal architecture/link building to show this preference My questions are; Will this harm our visibility? Aside from editing the sitemap, are there any other signals we could give Google? Thanks

[E-commerce] Duplicate content due to color variations (canonical/indexing)
Hello, We currently have a lot of color variations on multiple products with almost the same content. Even with our canonicals being set, Moz's crawling tool seems to flag them as duplicate content. What we have done so far: Choosing the best-selling color variation (our "master product") Adding a rel="canonical" to every variation (with our "master product" as the canonical URL) In my opinion, it should be enough to address this issue. However, being given the fact that it's flagged as duplicate by Moz, I was wondering if there is something else we should do? Should we add a "noindex,follow" to our child products and "index,follow" to our master product? (sounds to me like such a heavy change) Thank you in advance

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 -
Submitting URLs multiple times in different sitemaps
We have a very dynamic site, with a large number of pages. We use a sitemap index file, that points to several smaller sitemap files. The question is: Would there be any issue if we include the same URL in multiple sitemap files? Scenario: URL1 appears on sitemap1. 2 weeks later, the page at URL1 changes and we'd like to update it on a sitemap. Would it be acceptable to add URL1 as an entry in sitemap2? Would there be any issues with the same URL appearing multiple times? Thanks.
