Joined three ad programs today

Aside from my search optimising tasks from my client, I have joined three of the best and long term affiliate programs in my blog and these are:

1. Amazon

2. Adbrite

3. Azoogle (pending)

One of the top bloggers today which is John Chow, advised me to keep joining more affiliate programs because you will gain a lot more potential earnings from your blog. I am so attracted with Amazon because it pays 4% to 6% commission per sale, and for Adbrite it pays per click and CPM (cost-per-milli) or 1,000 hits. Together with search optimising, these ad programs are going to add up my potential earnings in the near future.
