I searched 'seo uk' and clicked on one of the ads because it was a company i hadn't heard of before, and the ad lead to this URL :
http://www.firstfound.co.uk/lp/201608/adwords/seo-na/?k=Best-SEO-Company&gclid=CjwKEAjwps2_BRC5jduHor-h8xESJADGT-LtGgBkhPrHl5EnCObA3N2H90bE5_Iaxbwat6xzY0KmtxoCUeDw_wcB
not a very good ad for the company unless people take the trouble to navigate to the home page!
