Several people ask me how to improve ranking of their Websites. Often I tend to send them to this Google 101 article. That is what you should have in mind if you are developing a site and want to understand how Google crawls it.
However, when developing it is important that you understand what you should and should not do in order to respect the organic results. Here they are, The Webmaster Guidelines. By following these guidelines, you will help Google to find, index and Rank your Site and avoid unnecessary problems.
I hope these light articles will help you to understand more about Google WebSearch in particular and SEO.
Have a nice day
