I find this keyword red shoes has a 10,000 searches volume. I search "red shoes" in Google and "red shoes" has 1,000,000 SERPs. But I also find nobody use domain to SEO this keyword. All SERPs are pages.
Should I SEO this keyword? No domain still means high competetion?
Many guides I read are going to tell me that I shouldn't SEO this keyword. But I don't know why.
Someone can explain it to me?
