Hi, One of my old clients referred me to his friend and now I am doing SEO (link building). He has 2 words keywords which are very tough to rank. His own SEO employees cannot rank it. I ranked them and now he says if you got under 5th position then I will pay you $700. If you are on 2nd position then $900 and first $1100. I thought he is paying me for each keyword but yesterday on our telephonic conversation he said if you got all 5 kws on under 5th position then you will get many more projects he has around 49 websites. Now I am confused. Should i charge him on keyword bases or all 5 keywords under $700, $900 and $1100 price. I am doing campaigns individually for each keyword and its continuous link building. Do guide me gurus.
