How Much Do I Bid?
The bigger PPC engines such as Goto and Sprinks require a minimum bid of $0.05. Startup engines have lesser minimums of $0.01.
How much to bid depends on your return-on-investment (ROI) calculations.
For example: If you bid $1.00 per visitor, and 1 in every 10 visitors buys your product, your cost-per-sale is $10.00.
So if each sale of your product produces a gross profit of $15, then your net profit will be $5.00 ($15 gross profit minus $10 cost-per-sale).
Your return-on-investment (ROI), before non-marketing expenses, is 50.0% ($5.00 net profit / $10 cost-per-sale). Always price your bids to achieve a positive ROI!

How Do I Track Clicks?
Most of
time, you'll notice that
number of clicks tracked by yourself is between 15% to 30% more than
clicks
PPC engine reports.
This is because reputable PPC engines such as Overture have installed anti-cheating mechanisms that prevent your competitors from repeatedly clicking on your listings and wasting your bid fees!
They will count multiple clicks within a specified timeframe from
same computer as only one clickthrough while your own log will usually register
multiple clicks.
There was once when I noticed that my log was registering less clicks than Overture's reports. They were experiencing some bug which prevented clicks from being properly delivered to
advertiser's website.
Because I was tracking my clicks, I notified them of
problem and they credited my account for
bad clicks. Tracking your clicks give you a more reliable picture of how well your PPC campaign is performing.
If you have access to your CGI directory, I recommend LnkinLite, a small yet powerful tracking software that can track clicks to your site in
background. Get it at http://www.dtp-aus.com/cgiscript/lnkinlte.shtml
Otherwise you can consider free online trackers at http://www.hypertracker.com or http://www.linkcounter.com
