Alexa tells us there are 18 million unique sites on the Web, but…
if you take Alexa’s Top 100,000 sites you’ll find that almost 3 out every 4 clicks are spoken for. In other words, almost 75% of all the traffic on the web goes to the sites in the Top 100K list, leaving the remaining 18 million or so sites to fight over the scraps.
Like the distribution of wealth on the planet, the distribution of traffic on the Web is extremely lopsided. The Top 500 are champagne and caviar. Sites 501 – 100,000 are meat and potatoes. The rest are hungry.
