So you are selling your website. Now you have questions, like how do I transfer ownership to the new buyer?
Well first off you want to be sure the payment was received before transferring anything. Generally using Paypal for payment is good, but if you are selling a high dollar site, you may want to consider a Bank Transfer or Escrow. The buyer may also want to use Escrow to protect themselves. Escrow is like a third party that makes sure everything goes through ok. You can learn more about Escrow services on the web, but it is not difficult. Once payment is verified, you can proceed.
Basically a website will have 2 things (although some could have more)
1. A Domain Name. Your Domain Name is the URL of your site. For example: SnicksList.com. The Domain is registered to you and will need to be registered to the new owner. You will need to go to the registrar and login to change the information. You may have registered your domain and then setup hosting with another company, or you may have done it all through one company, like HostGator for example. Regardless, you need to determine who the registrar is and change the contact and billing information. If you don’t know who the registrar is, try contacting your hosting company or try looking it up at: Whois.net
2. The Hosting Account Billing. It is possible that the new owner wants to host it with someone other than who you are using. They can request with their hosting company for the site to be moved. They will need an EPP/Authorization key from you before they can transfer it. Ask your hosting company for it and send it to the new owner. If they are keeping the same host, just go into your hosting account and change the billing info and password to the new owners information. You can change the password to something like newowner123 so that you are not giving away yours. They can then access it and change the password to what ever they want.
Recap:
1. Change the domain name contact (and billing) info with the registrar.
2. Change the hosting account contact and billing info. (If transfering it to another host, have the new owner start request the transfer and ask your host for an EPP code.)
If the website has other things included, like say if it is an e-commerce site, you would probably be giving the new owner the contact information for the suppliers you use. Sometimes the site may use Aweber (for managing contacts and emails) or you may have set up support software. Try to have all the information for any other services/parts of the operation all ready to speed up the transfer. I usually start getting it together as soon as I have a solid prospect. Like I said before, I usually change my passwords to something new to give to the new owner. It really is not as hard as it may sound, just think of what you would need if buying a site and you will be fine.
If anything, ask your hosting company what is required and how to change the necessary information and they should help you out.
