Can anybody explain about drop down keywords in Google Suggestion Box ?

Hi Friends,

Google suggestion box is showing different keyword suggestions when we type anything in Google Search.

What my problem is recently when I typed a keyword of mine in Google, it is showing some inappropriate keywords along with my keyword. These keywords are negative and inappropriate. I am not mentioning those keywords here because, if I write those keywords the volume of those negative keywords may increase. That is why i am not mentioning those negative keywords.

These negative keywords causes very trouble to my website. Because of those keywords, the value of the site as well as Company drops.

My sincere request is please give the solution for " How to remove Negative or inappropriate keywords from Google Suggestion Box ? "

Or

"How to overcome those negative keywords with positive keywords with the help of SEO?"

Anybody, please help me if you know the solution.

My mail id is sharonlaura@ymail.com

Sharon
