How Moz takes a page title is duplicate?

[vayush]

Suppose i have added suffix and prefix to each of my product (ex: i have two tittles like buy online t-shirt at abc.com & buy online poster at abc.com, so in this buy online and abc.com are suffix and prefix) so .. will it take these two page tittles as duplicates ?

No, they wont be treated as duplicates - neither at Moz and nor under Goggle WMT

Take it this way - you are selling apparels - so by default the page title would be including the product name. This will mark the page unique as long as the internal text, product description and content of the page too also is regarding the information about that apparel

If it helps, you may accept this as answer
