If you have a website of your own, I am sure you wouldn't want that to be taken down just the way I wouldn't want mine too to be taken down. Since we run websites for one good reason or the other, we have to incur some necessary costs on keeping it live and functional. These costs include registering a domain name for the website, hosting the website, and performing the various search engine optimization tasks for the websites.
To ensure that your website does not get taken down, you must be fully active online, ensuring that all possible ways to get traffic to your website should be worked upon. If it entails spending some little amounts of money, you should be willing to spend it.
