Lots of talks going on these days regarding the use of managed crowd search to inflate rankings. Crowd search means you pay real people to search google for your keywords for which you are ranking may be in 2nd,3rd or 4th page etc and then visit your site and spend time making it look natural to google. Seo guru claim that one of the key factor in google algo is the ctr (click through rate). How many people are visiting a particular site from serps. If you are getting higher ctr than the site above you then google may place you above. Have you guys tried this.
