{ Urgent Help } – How to hide coupon listings urls in google search .

Last week i have installed theme in my site and noticed that my one coupon url is indexed at google search .
I want to index only store urls on google and don’t want to index coupons url .
Indexing coupon url will hurt the site seo as it doesn’t have enough content .

Before buying this theme sales staff told me that coupons url will not index in google but now its indexing on google .
You can check it at site:bankoffersclub.com

Is there any other way to stop showing coupons listing on google search rather than setting it noindex from Yoast SEO Plugin .

Waiting for quick reply

Thanks
