Footer size and construction somewhat depends on your location and type of dirt, etc. Living here in New Mexico the frost line is relatively shallow so a 14 inch deep footing was all that was required. I happen to have a bunch of cinder blocks left over from another project, so I used those. I simply stacked the cinder blocks without mortar and packed the cavities with dirt.
You don't want the CB's to be in contact with the earth as they will wick up moisture and degrade. With the cinder blocks being above ground level, I then started with the rows of CB's, each level mortared. You can stack these blocks without mortar but that makes it difficult to keep each course level, as each block varies in size slightly.
It has been up for 3 years now and it has not budged one bit. No cracking, degrading or any signs of movement.
