I have been doing freelance projects and the clients initially with me for first 3 months. After they get on top of the search engines they simply asks me to stop SEO. Every client is doing the same things. Can anyone help in sustaining these clients. What i have to do. I also inform them that if we stop SEO then naturally the competitors will come up and our site will be pushed down. It is also happened for few clients who had stopped SEO with me. Is it possible for me to maintain a long term relationship with those clients.? How can i achieve it.?
