Hi onlineexpo,

in short: No, there is not that much potential in the finnish market to generate 100.000 Clicks on finnish relevant sites who use adsense within 2 weeks. No good idea. Use AdWords first, these clicks are more expensive, but they have better performance, that after all, the AdWords search traffic performance will be better than AdWords Content (AdSense) traffic performance. Use the Google Keyword Tool and Traffic Estimator to generate Keywords (also long-tail keywords).

Some random points you have to consider:
- What are your goals (for example: With a budget of xyz: Generating new customers at the max CpL at xx €)
- You need a decent keyword-based tracking system, best would be an automated bidmanagement system for adwords like searchignite, td searchware, doubleclick dart search et. al.
- You need a deep understanding of Google AdWords, try to make the google advertising professional test first, to see where you are.

After all. you really need a professional company or sem consultant, who plans and operates that campaign, otherwise you _will_ burn that money.
