This is a good list.<p>Press&#x2F;Retweets in and of themselves aren&#x27;t progress but they can be a good indicator of it (and also a poor indicator). I&#x27;ve had many conversations which have turned into sales that included that person talking about how they&#x27;ve been seeing my site everywhere these days.<p>Eyeballs&#x2F;Uniques are precisely why the advertising I sell is done on a monthly basis. Either the advertiser will like the results of the campaign by tracking the activity on their site, or they won&#x27;t.
