Can we know how fast google will index our webpages? As soon as you click 'submit post' button? What is the fastest time of google indexation rate? o.o5 sec? and what the slowest time of indexation rate? 2 day? just tell here if you ever experience that
Submit the website to google and you should be indexed (even if with <5 pages) almost instantly... Like in a few hours or less. Also, if you submit your site to google webmaster tools (as well as yahoo & bing webmaster tools) even better. This will mean also google analytics and pfft, you befriending google. +1 & adsense > fb like & cpa!
There is no fixed amount of time that will be required by Google to index your page. If the site is around five pages then it might get indexed instantly. It also depends on the information the site is sharing.
