Google Adsense Tips and Reviews

As I found, there are new earning terms for referrals were established:

* AdSense:
o When a publisher who signed up for Google AdSense through your referral first earns $5 within 180 days of sign-up, you will be credited with $5.
o When that same publisher earns $100 within 180 days of sign-up and is eligible for payout, you will be credited with an additional $250.
o If in any 180-day period you refer 25 publishers who each earn more than $100 within 180 days of their respective sign-ups and are all eligible for payout, you will be awarded a $2,000 bonus (bonus payouts are limited to 1 per year).
* Firefox plus Google Toolbar: When a user you've referred to Firefox plus Google Toolbar runs Firefox for the first time, you'll receive up to US$1 in your account, depending on the user's location. Your referral must be a Windows user, who has not previously installed Firefox, in order for you to receive credit.
* AdWords:
o When an advertiser you refer first spends $5 within 90 days of sign-up (in addition to the $5 sign-up fee) you will be credited with $5.
o When that same advertiser spends $100 within 90 days of sign-up, you will be credited with an additional $40.
o If in any 180 day period you refer 20 advertisers who each spend more than $100 within 90 days of their respective sign-ups, you will be awarded a $600 bonus (bonus payouts are limited to 1 per year).
* Pack: When a Windows user you've referred to Pack downloads and installs the product, you'll receive up to US$2 in your account.
