Duplicate title while setting canonical tag.

[ASKHANUMANTHAILAND]

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.

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.

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: ?showForm

etc., 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!

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.

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.
