Hello, I am confused to what I am seeing in this product meta tags [English Products Name: Harley Davidson post earring in 316L carved words Products Model: HDE-1 Price: $15.00 Title/Tagline: Cheap wholesale jewelry | Cheap used cars | guaranteed used car loans | cheap electronics
Meta Tag Title: Earrings in 316L with Carved words Harley Davidson motor cycles
Meta Tag Keywords: Harley Davidson jewelry, fashion earrings, biker earrings, hog jewelry, stainless steel jewelry,
Meta Tag Description: 316L stainless steel earrings with carved words Harley Davidson Motor Cycles.]

The top Title/Tagline say my website title, should this not say the Meta description for the product. As I believe the search engines are just reading the Title Tagline and not the product descriptions. So I think my products are not showing in separate pages? Can you explain this to me please.
Thank you,
Ron
