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.

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/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,

Best-practice URL structures with multiple filter combinations
Hello, We're putting together a large piece of content that will have some interactive filtering elements. There are two types of filters, topics and object types. The architecture under the hood constrains us so that everything needs to be in URL parameters. If someone selects a single filter, this can look pretty clean: www.domain.com/project?topic=firstTopic
Intermediate & Advanced SEO | | digitalcrc
or
www.domain.com/project?object=typeOne The problems arise when people select multiple topics, potentially across two different filter types: www.domain.com/project?topic=firstTopic-secondTopic-thirdTopic&object=typeOne-typeTwo I've raised concerns around the structure in general, but it seems to be too late at this point so now I'm scratching my head thinking of how best to get these indexed. I have two main concerns: A ton of near-duplicate content and hundreds of URLs being created and indexed with various filter combinations added Over-reacting to the first point above and over-canonicalizing/no-indexing combination pages to the detriment of the content as a whole Would the best approach be to index each single topic filter individually, and canonicalize any combinations to the 'view all' page? I don't have much experience with e-commerce SEO (which this problem seems to have the most in common with) so any advice is greatly appreciated. Thanks!0 -
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]

Case Sensitive URLs, Duplicate Content & Link Rel Canonical
I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

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

URL mapping for site migration
Hi all! I'm currently working on a migration for a large e-commerce site. The old one has around 2.5k urls, the new one 7.5k. I now need to sort out the redirects from one to the other. This is proving pretty tricky, as the URL structure has changed site wide. There doesn't seem to be any consistent rules either so using regex doesn't really work. By and large, the copy appears to be the same though. Does anybody know of a tool I can crawl the sites with that will export the crawled url and related copy into a spreadsheet? That way I can crawl both sites and compare the copy to match them up. Thanks!
