Google is like the ageing history teacher you had at your secondary school-coming across all cool and friendly, but if you push the boundaries too much you’ll get a board rubber thrown at your head. If you (or your Busby SEO Test friend) think you’ve come up with a great way to trick Google, think again. It’s been done, it’s been spotted and anyone else who tries it will be penalised. Google hates cheats and the penalties can be severe.
The highest-profile case of Google throwing its toys out of the pram has to be the German BMW site in early 2006. BMW.de had created a load of keyword-heavy “doorway” pages that were only visible to the Googlebot; human users would be redirected to a different page. Now this goes againts Google’s rules:
“If an SEO creates deceptive or misleading content on your behalf, such as doorway pages or ‘throwaway’ domains, your site could be removed entirely from Google’s index.“
Google’s response? Well BMW.de was effectively removed from the Google’s index; they no longer existed as far as searchers were concerned. They were given a PageRank of 0, no cached versions of pages could be found and there was no mention of BMW.de anywhere within Google. Are you remember about one of the famous blogger “John Chow” is punished for his ‘evil’ ways at variance with Google Slogan “Don’t be evil” 
. Imagine how its can be happen to you. Pretty harsh. you can learn from that and how john chow can get his ranking on google. Well, Following the webmaster guidelines can help Google find, index and rank your site. Good Luck!
