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.

Canonical or hreflang?
I have four English sites for four different countries, UK, Ireland, Australia and New Zealand and I want to share some content between the sites. On the pages that share the content, which is essentially exactly the same on all 4 sites, do I use the hreflang tags like: or do I add a canonical tag to the other three pointing to the "origin", which would be the UK site? I believe it is best practice to use one or the other, but I'm not sure which make sense in this situation.

Can I set a canonical tag to an anchor link?
I have a client who is moving to a one page website design. So, content from the inner pages is being condensed in to sections on the 'home' page. There will be a navigation that anchor links to each relevant section. I am wondering if I should leave the old pages and use rel=canonical to point them to their relevant sections on the new 'home' page rather than 301 them. Thoughts?

Can OG titles be used as a substitute for Meta titles
We use og (open graph) titles in lieu of meta titles. Is there any downside to using just one. Should we be using both og and meta titles on our page. Appreciate any insight. Himanshu

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.

Why is Google replacing our title tags with URLs in SERP?
Hey guys, We've noticed that Google is replacing a lot of our title tags with URLs in SERP. As far as we know, this has been happening for the last month or so and we can't seem to figure out why. I've attached a screenshot for your reference. What we know: depending on the search query, the title tag may or may not be replaced. this doesn't seem to have any connection to the relevance of the title tag vs the url. results are persistent on desktop and mobile. the length of the title tag doesn't seem to correlate with the replacement. the replacement is happening at mass, to dozens of pages. Any ideas as to why this may be happening? Thanks in advance,

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
Technical SEO | | philscott2006
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 -
Why "title missing or empty" when title tag exists?
Greetings! On Dec 1, 2011 in a SEOMoz campaign, two crawl metrics shot up from zero (Nov 17, Nov 24). "Title missing or empty" was 9,676. "Duplicate page content" was 9,678. Whoa! Content at site has not changed. I checked a sample of web pages and each seems to have a proper TITLE tag. Page content differs as well -- albeit we list electronic part numbers of hard-to-find parts, which look similar. I found a similar post http://www.seomoz.org/q/why-crawl-error-title-missing-or-empty-when-there-is-already-title-and-meta-desciption-in-place . In answer, Sha ran Screaming Frog crawler. I ran Frog crawler on a few hundred pages. Titles were found and hash codes were unique. Hmmm. Site with errors is http://electronics1.usbid.com Small sample of pages with errors: electronics1.usbid.com/catalog_10.html
