The aim for most people building websites or webapps is to create a source of revenue aka to become rich. This is a shallow goal, but definitely the most important in any business. It starts by building a prototype and getting paid for it. Most people seek to monetize their efforts by selling ads, but this is slippery slope because they’ll have to compete double.

Compete double is? the concept of competing in two completely different fields. By selling ads you’ll have to compete against Google, Facebook and many more for the advertisers; moreover, you’ll have to compete against other apps in your space. For example: If I was building an app to handle project collaboration, I’ll have to compete against Basecamp, Activecollab, Zoho and many more. On top of that, I’ll have to compete against many more for the advertisers money.

Be careful becuase monetizing is a slippery slope specially is your model is based on selling ads. It has worked great for Facebook or Google, but it may be a dead sentence for many because they’ll have to compete double and create the infrastructure to sell those ads.

What do I mean by creating the infrastructure to sell ads? It starts by having the proper technology in place to count, rotate and display the ads. There are many open source software that can be use for this purpose, but this is just deviating attention from the core product. People are needed to sell the ads or build that system to support it. It just adds a tremendous burden to the entire organization. Let’s assume the technology stack is already in place to support selling ads. I believe it is equally or more difficult to get somebody to pay for an ad that is to make people pay for your product or the vision of it.
