If I have a website that sells running shoes, I should map the keyword phrase 'Asics Gel-Kayano 20' to
1) a product page for Asics Gel-Kayano 20
2) a blog post about the benefits of Asics Gel-Kayano 20
3) a category page for all Asics running shoes
4) a homepage banner promoting Asics Gel-Kayano 20
