Since I am relatively new to traffic exchanges, I will try my best to explain how they work.
There are many, many different Traffic Exchanges and they all work similarly.
The way they work is when you sign up you will be given a free account with a chance to upgrade your account. A free account does not require any purchases so, I found that this is the best way to start until you get the idea on how to use them and see if it is working for you.
However, when you first sign up you will most likely be presented with an offer which is very hard to resist. For example, a lifetime membership to one of the highest levels for one price instead of monthly fees.
In any event the way traffic exchanges work is as follows:
Your account may start with some credits. These credits are worth visits to the site you are trying to promote. 1 credit is equal to 1 visitor to your website.
The way you earn credits is one of two ways: Either through purchasing credits or surfing. If you surf, you will start seeing other members ads for a set period of time. The time could be 15 sec, 20 seconds or even 30 seconds. After the set time has elapsed, you will be credited some fraction of a credit. Depending upon what level membership you enrolled in, depends on the conversion rate. It may be that 1 surf = 0.75 credits or it may be 0.33, or 0.5 or 1.0 or more.
The whole idea is that you post your ad as well through either text ads, text impressions or banners which also have a credit conversion to use.
So, what basically happens is that there may be let's say 30,000 members signed up with an equal number or more ads which are rotated based upon how many credits you assign to your ad. So, if you assign 100 credits, your ad will be continually rotated and displayed with everyone who watches the ads views your ad until 100 visitors have seen your ad. Then your credits will be 0 and then you start the process again. The advantage of purchasing credits is that you may be able to get 10,000 credits for perhaps $25.00. This means you can kind of set your ad going and not bothering to check it for a while until 10,000 visitors have seen your ad. Every one's ads are exchanged in continual rotation, much like when products on a shop at home cable channel are advertised.
If someone is interested in your ad, clicks your ad and makes a purchase, you get a commission.
If you just go with a free account, you will have to surf a lot by clicking other members ads to earn enough credits to start posting your own ad.
Safelists are similar except you are emailing your ads to the members. This is what I have learned in the online course. It is true that there may be a lot of individuals with the same ad. So, I think the key is to post a unique ad or hopefully find out what people are interested in, which is not easy.
Obviously, however, many people are successful with this, otherwise I would think that this business would have died off a long time ago.
That is my take on traffic exchanges. If I am wrong on any points feel free to correct me as I am still learning and understanding this.
