Meta tags in importing coupons

Hi,

I just want to know if we use import option for couponpress from icodes or any other service or xml feeds how do we write the meta tags because i guess it is not done automatically. When manually feeding coupons we can write it in the seo plugins like all in one seopack. And if it can’t be done do we really rely on promoting our site through social circle/media or we can expect the listings to appear in serps. what are the best ways to promote a coupon site?

Regards,
