How much FREE traffic can I expect? Lets be extremely conservative and assume that your page and everybody else's pages only get 10 sign ups:

Hits to your page 1: 10 people visit your page and get their own page,
producing 10 x 1 = 10 hits: 10

2: Those 10 pages each get 10 sign ups themselves,
producing 10 x 10 = 100 hits: 100

3: Those 100 pages each get 10 sign ups themselves,
producing 100 x 10 = 1000 hits: 1000

4: Those 1000 pages each get 10 sign ups themselves,
producing 1000 x 10 = 10,000 hits: 10,000

5: Those 10,000 pages each get 10 sign ups themselves,
producing 10,000 x 10 = 100,000 hits: 100,000

6: Those 100,000 pages each get 10 sign ups themselves,
producing 100,000 x 10 = 1,000,000 hits: 1,000,000 Total FREE hits to your site: 1,111,110
