If you are planning to buy or sell a website, you probably already heard about Flippa. It is the largest online marketplace for websites. Most people who list a website for sale there, however, end up selling it for peanuts (e.g., $100), or not selling at all.

How come? Most of the times the seller didn’t do his homework. If you want to maximize your chances of selling (and your profit), the 10 tips below will help you.

1. Make Sure Your Website Is Making Money
This is the most important factor. If you want to sell a website successfully, it must be making money. Even if your site has a huge traffic, listing it before monetizing that traffic would be a bad decision. You would be able to sell it, but the money you would get would be far below the real value of the site. Remember that you’ll need to show proof of revenue, and that most buyers will calculate the revenues as the average of the past four or six months.

2. Make Sure You Have Google Analytics Data
Most serious buyers will want to see your Google Analytics data before making an official offer. They will use this to verify your traffic levels, and to make sure the pattern is compatible with the revenues you are claiming.
Google Analytics on it at least six months before the sale.
