Trying to find what rank a website has for certain keywords in google (out of the top 100 results, case insensitive).

  Multiple keyword searches, spaces between keywords, one set of keywords per line:<br />

  target url:&nbsp;<input type="text" name="target_url"  maxlength="256" />
 <br />&nbsp;<br />
  <input type="Submit" value="Submit" />
