SearchWiki adds two buttons to the right of each result that let users move their favorite or most relevant results to the top spot or kill out a result entirely for their page only, as well as add notes for yourself on certain results and add entirely new results to that crucial first page.
“With just a single click you can move the results you like to the top or add a new site,” Google said. “You can also write notes attached to a particular site and remove results that you don’t feel belong.”
Others and you personally will be able to see the changes your username has made, along with aggregate numbers for other users’ actions.
In order to see how to use and do the changes, please watch the video given in the link below.
