Do you own any domain names that are parked? You have to be careful with advertising your domains. I put my domains up for sale in ads and also mentioned them in domain discussion forums.
Because a few of my domains received increased traffic and ad clicks, my parking account was canceled today. I paid over $100 for that account. In addition, the $250 sitting in the account will be voided out.
The lesson is to use hosting accounts that allow you to advertise your domains. It's not fair to keep your domains in the cave, especially when these domain companies do nothing to promote them. You have to spend money in order to make money.
When you advertise your domains, you're more than likely to receive traffic. The lesson learned here is that you have to read between the lines. If you plan to sell your domains, I would point them to another location such as a blog or an existing website.
Domain companies seem to make up excuse as to why they don't want to pay for commission. The same event took place when I used a coupon site to make cashback. The domain company failed to pay the company for referring me to their site.
In addition, I only received a small portion of the cashback, whereas now a large amount is unpaid for. You have to look into other alternatives to making money. Don't depend on domain companies to help you make a sale and or to paid up on revenue you've earned using their services. It's definitely some to think about when trying to sell and park domains.
