BungeeBones offers a unique business relationship between the BungeeBones “system” and the web master. For a website to go from being a BungeeBones customer (a “mere” buyer of our advertising (we love you! to a “partner” participating in the business opportunity it requires an investment on your part but not one inviolving money but involving web traffic coming to your site.
In order to do a financial assessment of the benefits of using BungeeBones you need to have a clear view of the financial investments you have already made into your website so that you have a general idea of the ROI (return on investment) that you are currently getting.
Without getting into too much detail, add up how much you spent building and launching the site. Then add up how much you spend to maintain it. Then, add the amount you spend advertising the website. That one is a bit difficult to place an absolute value on but every time you place your web address in an ad, which then causes that person to go to your website rather than going to your business, a portion of the cost of that ad should be (IMHO) attributed or charged to the cost of the website.
After you have added up all the costs of building, owning and operating a website then you need to come up with a realistic value of the income it generates. I suggest you use the same criteria that you use to assess all the other advertising methods you use because the main goal is to be able to compare the cost of web advertising to the other methods in order to determine the best place to spend your advertising dollars.
