Duplicate URLs ending with #!

[jayoliverwright]

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

The URL you displayed as an example looks like in-page bookmarking and as far as my knowledge goes this does not make the content duplicated.

But as far as the canonicals are concern, adding a canonical URL on the website is better as it can save you from any unforeseen problems but as far as the problem you are mentioning is concern, I don’t think this will create a duplicate content within your website.

Hope this helps!
