Advertise with Adsense. Advertise on 10 sites at a time, or only 1?

[John_Melin]

I have decided to advertise on about 10 different websites with Adsense. Should i spread my money equally between these sites and run the campaigns at the same time, or should i focus on one site at a time?

If i focus on 1 site at a time i will probably find the site that has enough ROI for my advertising without spending money on the other sites.

What do you think?

I would go with all 10 sites for 2 days , then look at stats to find ROI ,
You need to decide what YOUR ROI is
1 If for branding ( number of impressions per $ )
2 If clicks overall cost per click ( number of clicks per $ )
Or a combination of both
