posting tags on products and page

Hello

i was wondering guys what you think about this. I have a website like amazon and i was wondering for the products that i post like for example : (women jeans) should i be tagging each product that i post ? and should i tag my keywords to my website ? like my main 5 keywords in the tags or use other tags like (girls jean,jeans,women jeans) and so on ? or would i post my website keywords like (cheap shopping online,shopping online) ??

thank you

If you talking about an Amazon affiliate website, One of the ways you could use is to add affiliate links to the text and link to amazon. Alternatively you could have a product review page where you send visitors to from you blogposts. , that is instead of linking directly to amazon products , you link to a page on you website where you have reviews. Hope this helps.

yes i am talking about a amazon affiliate store or website.
but im manually posting the products and i want to know what tags is best to use for the products

following up . can someone help me out
