We’ve been looking at different angles for planning out the next bit of Ye Olde Directed Edge Roadmap and we’re starting to run some numbers on how the number of online stores and media sites breaks down in the US and I wondered, “What’s the breakdown of the top 100 sites in the US?”  It’s the kind of thing that’s good to know when you’re trying to figure out how many sites on the interwebs might be able to make use of a recommendations engine.

Here are the total counts — the results were a little surprising:

• Media – 15
• Service – 12
• Search – 10
• Adult – 10
• Content – 7
• Blogging – 6
• Social – 6
• Images – 5
• Gaming – 4
• E-Commerce – 3
• Brick & Mortar Store – 3
• Advertising – 3
• File-sharing – 3
• Video – 2
• Auctions – 2
• Hardware – 2
• Maps – 2
• Software – 2
• Jobs – 1
• Music – 1
• Weather – 1

The top-100 list came from Alexa, and some of the categories are a wee  bit ad-hoc, but it does give an interesting idea of what the break-downs are.  I wouldn’t have guessed, for example, that adult sites beat e-commerce sites by a factor of more than 3-to-1 in the US top 100.

The full data is here in a PDF.  Holler if you want the spreadsheet version to bang on.
