Take a glimpse at the procedure:

Take nothing for granted. Use every resource you have.....google, page title, page source, hidden links etc .No information is left accidental. If you think anything doesn't/shouldn't  belong to the page, then think again. Many a times ,the key to the next step is embedded in the page. So, don't trust any piece of information .Besides ,your brain should be with u through out the battle.

Now get on next page !
