How do you measure someone’s presence online? Everyone knows that 1 unique user session, is better than 1 visit, which is better than 1 page impression, which is still better than 1 hit. 1 unique user session, however, doesn’t compare to 1 videocast or podcast download or to 1 rss download of an article. 1 unique user session is nothing to getting 1 optin email address, or 1 person to post a comment. 1 unique user session is worthless compared to 1 new friend on Facebook, MySpace, or LinkedIn. 1 unique user session is meaningless to 1 indexed back link on Google, Yahoo, or MSN. Internet marketing is about learning to forget traffic, and think engagement.
