If Santa Claus said he would let you rank #1 for one term on Google for one week, what term would you want to rank for? Second question, if Santa said because you've been particularly good this year, he'll let you rank number one on google for one entire year, would you still pick the same term, or what would it be, and why? So, if you could rank #1 for a week, what would you pick? And if you could rank #1 for a year, what would you pick? And why? Merry Christmas!
I would like to rank #1 on Google for the keyword "web hosting". Why? Because there is a lot of money to be made with web hosting affiliates. They pay well.
The top keyword for porn niche. Everybody knows that already. I don't want to post it here. I might get banned porn = $$$$$$$$$$
I would ask for "Barack Obama", really just to mess with people. Or better yet, have santa add 100,000 global searches to the keywords I'm already ranked for.
With all the resources Google has.. I'm pretty sure in less than an hour, your #1 ranking in the word "Google" will be replace right away by the actual Google itself, heck they will even delete your network of websites in their SERP.
