I just discovered the following and wanted to share. The domain .com.com gets alot of traffic. This means if you add .com to any url ending in .com (ex. cnn.com becomes cnn.com.com), you will not end up on your intended page, but end up on the webpage for .com.com. I remember analyzing that domains traffic many year ago and was impressed by the volume. Unfortunately the PPC conversions were weak so we passed on it.
It seems that.xyz currently uses these accidental typos to redirect to a domain sales page for .xyz. I think the video on the page is well done. I’d love to know how its converting.
