Successful marketing takes patience
If you are sure that your website is capable of attracting a lot of traffic and generate a substantial amount of sales for a certain company, you need to contact them to negotiate some sort of business agreement. They might not be as enthusiastic in the beginning, but don't let that put you down. Be patient because companies are approached everyday by affiliates just like you wanting to cut a deal.This business is unpredictable, so you can't really make any promises. Companies are aware of this thats why they have second thoughts when recieving an offer from you regarding an arrangement. It might take a little while to gain some attention, post there ads on your website and see how it goes. Make sure you have a marketing strategy in place so that users can know that your website actually exists.
Hey who knows these companies who have second thoughts might have a change of heart.
good luck!
