Google released a report on general statistics of web pages on the Internet. The report lists basic information they retrieved over the course of “Google’s crawl and indexing pipeline.”
The key highlights include:
- The average web page takes up 320 KB on the wire.
- Only two-thirds of the compressible material on a page is actually compressed.
- In 80% of pages, 10 or more resources are loaded from a single host.
- The most popular sites could eliminate more than 8 HTTP requests per page if they combined all scripts on the same host into one and all stylesheets on the same host into one.
Google analyzed over 4.2 billion pages and of those, Google considered about 10% of those “top sites.” 17 million of the pages analyzed were SSL pages, which typical load slower and take up more server resources.
