Hello hestheman
Depending on the service provider who your order traffic from can determine who is honest, provides the best results. Most traffic sites don't show you where the traffic comes from, some do. Not all traffic sites are the same.
We run a network of sites, and domain names and when a client asks for a demo of how we deliver traffic we can show them in minutes live on line. If you order banners on our network you will see your banners live, and we give you a list of the sites they appear on, we can also show you how we deliver traffic with the domain names that we own with our master domain redirection sytem that we have in place.
No all traffic sites are honest, but you have to search for the good ones. Yes, at times we use other advertisers, and wholesales to provide traffic to clients. If we ever find an advertiser using unfair pratices, they no long do business with us.
Most traffic business's run on a part time basis, and there customer support is week. You should deal with someone who runs the business full time, and who has your interest in making your business gain actual visitors to your site. No traffic business can guarantee that people will either buy your products, or use your services, that is up to the site to deliver that.
