Adding a website is similar to adding to any other search engine. We'll obey any robots.txt files, so you must either not have one, or not disallow User-Agent "veryhip" from downloading at least the index file from your website.
Once you submit your URL, and we're allowed to index at least your main page, we'll categorize your website based on the keywords and content on your site. Others may rate your site. Your rating will determine how likely you are to appear as a similar site to others.
All we need is the URL to get started. You don't even have to log in. We review all sites, and flag spam sites. Once approved (approximately 72-96 hours), your website will get a link from us.
