my homework need within 10 hours..

I need at least 250 words each answer…

1. How are users paying Google for search-related advertising? How is it different from the way by which they pay for online ‘banner advertising’? How is the price determined in each case? 

 

2. Is Google facilitating, or limiting the Long Tail phenomenon in Marketing? (Read the Sloan Management Review article From Niches to Riches: Anatomy of the Long Tail).
