Duplicate title while setting canonical tag.
-
Hi Moz Fan,
My websites - https://finance.rabbit.co.th/ has run financial service, So our main keywords is about "Insurance" in Thai, But today I have an issues regarding to carnonical tag.
We have a link that containing by https://finance.rabbit.co.th/car-insurance?showForm=1&brand_id=9&model_id=18&car_submodel_id=30&ci_source_id=rabbit.co.th&car_year=2014 and setting canonical to this url - https://finance.rabbit.co.th/car-insurance within 5,000 items. But in this case I have an warning by site audit tools as Duplicate Page Title (Canonical), So is that possible to drop our ranking.
What should we do, setting No-Index, No-Follow for all URL that begin with ? or keep them like that.

Using the disallow directive in the robots.txt file is probably the better bet as far as making sure that our tools don't crawl those pages and report duplicate page titles. I think the disallow directive is the way to go!
That said, I'm not an SEO expert, so it might be worth checking in with a web developer to see if they have different suggestions.

Thanks for you guys and sorry for lately replied,
@tawnycase, I need to setting robot to ignore those link right ?, So in this case it must setting by dissallow ?parameter because I don't need to setting no index for main folders.

Hi there! Tawny from the Help Team here.
Even with a NoIndex, NoFollow tag on those pages, our tools will still crawl and report on everything up to that tag and report on it. The best way to prevent our crawler from accessing these dynamically tagged pages would be to block it from accessing them using the disallow directive in your robots.txt file. It would look something like this:
User-agent: Rogerbot
Disallow: ?showFormetc., until you have blocked all of the parameters or tags that may be causing these errors. You can also use the wild card user-agent * in order to block all crawlers from those pages, if you prefer.
Here is a great resource about the robots.txt file that might be helpful: https://moz.com/learn/seo/robotstxt
I hope this helps!

You'll definitely want to keep that canonical tag in place. Some tools don't recognize canonicals, so I wouldn't worry too much about duplicate notifications due to parameters like that. If you noindex that page, it will apply to the root of that URL, not strictly the parameter'd version.

Duplicate titles from hreflang variations
Hi, I am working on a large global site which has around 9 different language variations. We have setup the hreflang tags and referenced the corresponding content as follows: (We have not implemented a version X-default reference, as we felt it was not necessary) Using DeepCrawl and Search Console, we can see that these language variations are causing duplicate title issues. Many of them. My assumption was that the hreflang would have alleviated this issue and informed Google what is going on, however i wanted to see if anyone has any experience with this kind of thing before. It would be good to understand what the best practice approach is to deal with the problem. Is it even an issue at all, or just the tools being over-sensitive? Thank you in advance.

How long does it take for canonical tags to work
How long on average does it take for a canonical tag to work? Understand that canonicals are just a suggestion, but after adding a canonical tag and submitting the page via Google fetch, assuming Google follows the canonical, would you expect it to work after a day or two or does it take longer? We added canonicals to old PPC landing pages that are ranking organically, though our new landing pages (which we want to rank organically) are not identical and have a bit more content/features. They are similar though. Canonicals were added to the old pages (pointing to new pages) and requested indexing via search console. Old pages are still ranking and new pages not so much. FYI we are unable to 301 old PPC pages due to other non negotiable reasons unfortunately. Thanks.

Do URLs with canonical tags get indexed by Google?
Hi, we re-branded and launched a new website in February 2016. In June we saw a steep drop in the number of URLs indexed, and there have continued to be smaller dips since. We started an account with Moz and found several thousand high priority crawl errors for duplicate pages and have since fixed those with canonical tags. However, we are still seeing the number of URLs indexed drop. Do URLs with canonical tags get indexed by Google? I can't seem to find a definitive answer on this. A good portion of our URLs have canonical tags because they are just events with different dates, but otherwise the content of the page is the same.

301 redirect: canonical or non canonical?
Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

Duplicate Title Tag issue due to Shopify CMS
Hi guys, I'm a novice really when it comes to SEO, yet have taken it in house for the next year or so, firstly because I have had my fingers burnt twice...and secondly, to allow me to recoup some of the loss from my prior campaigns. One thing I have noticed on my site (which uses a Shopify E-commerce CMS), is that Shopify duplicates a url for each my products. An example of this is http://www.vidahomes.co.uk/collections/designer-radiators-heating/products/reina-aliano

http://www.vidahomes.co.uk/products/reina-aliano Both products provide exactly the same information, yet appear in different ways subject to how the customer finds them. I contacted Shopify to find a fix to this issue when I noticed a high amount of Duplicate Title Tags in my SEO crawl. Their response was as follows. Using a rel canonical link will help prevent duplicate content issues with search engines. All you need to do is add this line of code: **<link rel="canonical" href="{{ canonical_url }}" />** ** before the tag in the theme.liquid file. It’s that simple :)** The theme liquid file basically generates the outer template for the whole site, and is only compromised when over-ruled. This all seems a little too easy for me, so I am hoping whether someone can elaborate as to whether this will work or not, as I'm not entirely sold on their response. I was always under the impression with canonical tags, that they should be added to the header section of the duplicate page in question, which refers back to the original page. The code I have been told to add above implies that the canonical tag would be added to every page in my site so the Google robot would have a hard time in finding anything at all of relevance Thanks in advance for any assistance with this. Kind Regards Phil Scott Vida Homes0 -
URL query strings and canonical tag
Hi, I have recently been getting my comparison website redesigned and developed onto wordpress and the site is now 90% complete. Part of the redesign has meant that there are now dynamic urls in the format: http://www.mywebsite.com/10-pounds-productss/?display=cost&value=10 I have other pages similar to this but with different content for the different price ranges and these are linked to from the menus: http://www.mywebsite.com/20-pounds-products/?display=cost&value=20 Now my questions are: 1. I am using Joost's All-in-one SEO plugin and this adds a canonical tag to the page that is pointing to http://www.mywebsite.com/10-pounds-products/ which is the permalink. Is this OK as it is or should i change this to http://www.mywebsite.com/10-pounds-products/?display=cost&value=10 2. Which URL will get indexed, what gets shown as the display URL in the SERPs and what page will users land on? I'm a bit confused so apologies if these seem like silly questions. Thanks

Should there be a canonical tag on my 404 error page?
In my crawl diagnostics, I notice some 4xx client errors. They are appearing for pages that no longer exist, so I'm not sure what the problem is. Shouldn't they just be dealt as 404's? Anyway, on closer inspection I noticed that my 404 error page contains a canonical tag which points to the missing page. Could this be the issue? Is it a good idea to remove the canonical tag from this error page? Thanks.
