Welcome to WebmasterWorld Guest from 126.96.36.199
To give you an idea about the ballpark my site is in: 150 hits from page 1 on Google in December (300 hits so far in January).
Bids for my keywords are low - most less than 10c. Will I ever spend the $100?
Sprinks also has a new minimum...so most of the bids you might be seeing are only in pure search, not guidesites or they are grandfathered.
i seem to remember hearing something about a .20 thing - that might be to get place on a subject area or within a newsletter - not sure on that.
