ScriptMedia

I need a script that generates hits on my sites from keywords that are typed into search engines. The script aims to identify the machines or people who are searching for those words and when it accesses a site a new tab appear along with a pre defined site for us. so the browser will have two tabs open one with the site which entered related to the keyword searched in search engines and another tab with a page that will post. I know it's right because there Medias using visits to sell to your customers. The budget can talk, make proposals. Thank you
