Project Wonderful is a resource that enables users to economically advertise on other project wonderful members blogs and websites. Project Wonderful is in essence a broker of advertising; keep in mind the word broker because I'm going to come back to this later.
When you sign up with Project Wonderful you begin by depositing money into an account so that you have funds to advertise with. Then you begin searching for blogs or websites that you think fit what you are trying to sell. Keep in mind that you don't have to advertise on sites that are similar to your market, the best practice is to find sites that are outside of your genre, but attract your potential buyers.
Advertising can cost nothing, pennies, or dollars per day. Obviously, you want to find the best places to advertise at the lowest cost. What you will be doing is actually bidding on an advertising position. If you look at the right column, of my blog and find, the four project wonderful ad spots, below that is the amount it currently costs to advertise. In my "bidding on my ads" queue on Project Wonderful are many more than four people vying for those ad spots. That is how the price to advertise is determined and the reason it fluctuates. Also, not all of those spots are going for that listed rate, some are less, but that is the amount to buy into my advertising space now.
When I place my advertising, I search out spaces that look like a fit for my product. Then I place my bidding range. I look at the advertisers stats and place my bid accordingly. I will start my bid at .00 up to what I deem reasonable. Here is the important part and where brokering comes into play. I always place my bid for a month or more. Usually three months. You may be saying, "well I can't afford that!" Well, you probably can. The reason is that your ad is not going to be up all of the time and you only pay for the space if it shows up that day.
Keep in mind that on the blog/website that you want to advertise on other ads are going to expire. When those ads expire and if your bid fits, you have the opportunity to get your ad on that space, at least until it is bumped by a higher bidder. It may also appear at the least cost that you bid. So you may be getting great exposure for almost nothing. If the advertiser has more than one ad space you should always click on each space for advertising potential. While the top or bottom space may seem to be a premium position, in this case it doesn't really matter. What you want is to get your ad up there at the least cost and most exposure. I believe on blogs as you are scrolling down, if that space catches your eye, you are going to look at all of the ads anyway and decide to click or not.
Brokering these ad spaces is a lot like the stock market. You want to buy in at the lowest price possible and get the most return on your investment. Putting your ad up for only a day or two generally means you are going to pay the highest price that you have bid. Putting your ad up over a period of a month or more, means that you will get more exposure for either a lower or equal cost. Just like in the stock market, you generally get a better return the longer you can leave your investment grow.

To recoup your costs you should also consider putting advertising on your own blog or website for people to purchase from you. I invested $25 into my Project Wonderful advertising account last March and have never had to add more funds. My account fluctuates between having $20 and $35 to spend, depending on the amount of advertising I am running and what I am earning. I always have advertising up and running. I truly believe that recognition of a brand is important. So, if you see my avatar in many different places you may at some point click and find out who is behind that avatar –which may in turn result in sales.
