There are over 1.1 billion websites on the internet, but the vast majority of all traffic actually goes to a very select list of companies. Google (GOOG) for example, has an astounding 28 billion visits per month. The next closest is also a Google-owned property, Youtube.com, which brings in 20.5 billion visits.

Today’s infographic comes to us from Vodien, and it lists the 100 highest ranking websites in the US by traffic, according to website analytics company Alexa.

The information is grouped by company – for example, you can see that Google controls four sites in the Top 100 (Google, Youtube, Blogger, and Google User Content), while Verizon owns the Huffington Post and AOL.com (they will also control Yahoo (YHOO) and Tumblr when that deal closes in Q2). The data is also sorted by industry, so sites in a similar category are grouped in the same color.

A Steep Drop-off

The dropoff from #1 to #100 is significant. Google.com has 28 billion visits, but a website like Citi.com (ranked #98) only has 53 million visits a month. That’s a 500x difference!

Meanwhile, a website like ours gets one million visits per month, and is ranked #33,000 in the United States – a 50x difference from Citi (C). Further down the trail – there are literally millions of tiny websites that get thousands or just hundreds of visits per month, and some that don’t get any love at all.

The whole distribution is quite fascinating, and it is clear that the spoils go overwhelmingly to the very top of the food chain. However, that also means that there is an entire world of millions of websites out there that almost no one (except Google’s crawler) has ever seen.
