Services.
Compete.com provided two categories of information: 
Compete Toolbar.
The Compete Toolbar allowed users to view the Compete Trust Scores and the US Internet ranks of websites they visit. This was done by sending the URLs that users visit to Compete.com. Compete.com then sent back the trust scores and internet ranks from its database to the users.
Additionally, users of the Compete Toolbar had the option of participating in Community Share. By participating in Community Share, users were assigned a user number, and that number will be submitted along with the URLs of the websites that these users visit. This information was used to roughly determine how many users visit each website.
Although no personally identifiable information was submitted to Compete.com, the server received the originating IP address.
History.
