Observations on Web Site Data

How compressible is web data? For a recent project of mine...

• 135 GB of web pages downloaded.

• 15 GB of actual data extracted.

• 0.6 GB compressed data archives.

So, about a 25:1 compression ratio for text data.

Derived from the above:

• 15/135 ~= 10%

So, approximately 90% of the web is crud.
