What You Shouldn't Use Ads as Your Primary Business Model

Only 3% of the top 100 YC companies use an advertising business model as their primary way to make money. We can also see that very few advertising businesses become big winners. And so it's really important to remember that you should not use ads as your primary business model, unless you expect to be a top 10 site on the internet. Otherwise, it's too hard to monetize and build a huge scale to become a massive company.
