Is there anyone can help me with the question of SEO?

I'm struggling with this particular client I want to change some of his website. But we are not going well and the website there is a need to change the client suggests some changes to the Web site could get penalized in the first place. I do not like the idea and the client has been proposed for the fix, to see the discomfort on my face is not listening to his suggestions. I suggested his way to convince the client that might destroy his web site even more than previously available? Do you have any suggestions anyone?
