Hello I know someone who sells men's clothing on his website. He has never done SEO and wants to hire me. He has asked for a price quote and I really don't know how much I should say. I have checked keywords like "mens clothing store" "mens suits online" "buy mens tuxedo online" and these seem extremely competitive. Am I right that these keywords are extremely competitive? And I think the search volume is not very much. So I am not sure how an online clothing store like this could invest in SEO. is my logic wrong? How much should I charge?
