Welcome to the Q&A Forum

I currently launched my eCommerce startup hosted in Shopify and linked with MOZ. From my first Crawl Report I am getting 580 Duplicate Page Title i.e. all my Collection page have the same title. I have googled and have been checking the MOZ community but cannot find a fix to it. Some of the URL's are -

http://www.onlypetstore.com/collections/all

http://www.onlypetstore.com/collections/all?page=10

http://www.onlypetstore.com/collections/all?page=100

http://www.onlypetstore.com/collections/all?page=101

http://www.onlypetstore.com/collections/all?page=102

http://www.onlypetstore.com/collections/all?page=103

I am new to SEO and any suggestions will be a great help to me.
