[UPDATE] Its been 4 days since I paid and here are the results so far:
The 3 sites I'm using are:
1) 5 year old site
on page 2 right now for the targeted keyword which gets 3,000 searches a month according to google keyword tool.
RESULTS TO DATE: dropped to page 3
Since this is a site that has been around for years, it will be a good measurement.
2) Totally new domain
single page site
targeted keyword gets 3,600 searches per month
RESULTS TO DATE: indexed and on page 10 of google
3) Totally new domain
multi paged, highly SEO optimized site (proven by real life first page ranking achieved last month, site taken down due to investors pulling out)
targeted keyword 320 searches per month
BTW 1st page achieved for keyword that got 880 searches per month without any SEM(offsite SEO)
RESULTS TO DATE: indexed and on page 15 of google
