Hi there,
Your question isn’t quite as simple as that. Conversions always depend on the quality of traffic and I find general averages of little value unless the source of the traffic is known.
For example, Pay Per Click search engines vary considerably, from my experiences.
Overture has consistently converted better than 3% for Unique visitiors to real money players. 7 Search on the other hand has been around 0.5% conversion.
Also, conversions may not have any meaning unless you factor in the cost of the advertising and player value. Again, Overture may convert at 3% or 30 real players for every 1000 uniques, but it may have cost you $7 per click through. 7 Search on the other hand may have only cost $0.30 per CT and produced 5 real players for every 1000 uniques. So whats the per player value and which got the best result based on cost of advertising versus player value. If player value was $300 per, then Overture cost $7000 and paid out $9000. 7 Search would have cost $300 and produced $1500.
Also, consider other factors, branding value, advertising that gets you lots of views but little conversions is still a a positive thing even though immediate monetary rewards are negligible. Then theres the issue of traffic volume. I’ve used PPC’s that have great conversions for me, but they were so small that even with great conversions they never generated enough traffic to even make a dent in my bottom line.
Keep in mind these scenarios are only hypothetical but it helps you understand what I’m getting at.
FYI – The only PPC’s I’ve ever made a “serious” profit with are Overture, Findwhat and ePilot. ePilot only made it because it landed me a few whales (players who spent more than $10,000) and 7 Search gave me players but they always seemed to win!
Hope this helps you think about things in terms of profit rather than general conversions.
