We will be launching an e-commerce website that will focus on the sale of refrigerator filters and other replacement filters. Important keywords will include the major brand names of refrigerators. For example Samsung fridge filter, LG fridge filter, Whirlpool fridge filter etc. we will also have the major part numbers listed. We will have over 100 different models to choose from. a client wants me to do the seo for 3 sites all targeting filters 1 for canada 1 for usa and 1 for the rest of the world these are some serious highly competitive keywords he wants to rank for and told him he would need a huge budget and still maybe it wouldnt rank what would be a decent price i could charge him a month?
