Average Web Page Breaks 1600K
Summary: The size of the average web page passed 1600K for the first time in July. Page size appears to inversely correlate with site traffic.
The size of the average web page of the top 1000 websites passed 1600K for the first time in July (see Figure 1). At the same time the number of objects in the average web page increased to 112 objects in July 2014.

Average Web Page versus Survey Size
In the HTTParchive.org site, the data also revealed that the average web page for the top 300,000 pages is 1829K in size made of up 96 objects on average. So the top 1000 pages have more objects (112 vs. 96) but less K (1622K vs. 1829K). The top 100 web pages average 1612K with 90 requests per page (see Figure 2). So page size appears to be inversely related to site traffic. The more traffic a site has, the smaller the pages. For the average number of web objects the correlation holds true for the top 100 and 1000 pages, but not the top 300,000.

The Effects of Caching and other relevant statistics
Charzinski's 2010 paper shows the beneficial effects of caching on performance. Table 1 shows that the average top 500 home page goes from 507K and 64.7 requests upon initial cache-cleared load to 98.5K and 16.1 requests. One average, caching on these popular sites saves 81 percent of the bytes, and 75 percent of the requests.
Other data from the study showed that Akamai still dominates CDNs, with 43.6 percent of the top 500 using Akamai, delivering 22.3% of the initial load, and 25.8 percent of the cached loads overall. Limelight, Footprint, Panther Express and Google round out the top five CDNs. 167 (33.4%) of the top 500 sites employed one or more of the Web 2.0 technologies (XHR, JSON, or GWT Google Web Toolkit).. 38 percent employed from 1-10 web bugs on their home pages.

- e-mail to author (July 27, 2007). In a random survey of 500 pages indexed by Google for the author, 62.6% of pages used the TABLE tag while 85.1% used the DIV tag. Tables nested to an average maximum depth of 1.47, with an average number of 12.57 table tags per page. The average maximum HTML depth was 15.35, demonstrating how DIVs are replacing table nesting.

Using the Googlebot, Sreeram analyzed both 380 million top sites and 4.2 billion websites to see what the average web page consists of. He found that the average web page is 320K in size, using 43.91 resources per page.Just 66% of compressible bytes were compressed using HTTP compression in the entire Web. 64.3% of the average web page was taken up by images (205.99K of images divided by 320K size of average web page). There were 7 scripts and 3.2 external style sheets. The uncompressed size of the top sites was 477.2K, while the uncompressed size of the average web page (4.2 billion) was 376.7K. Interestingly, the top sites network size (bytes delivered down the pipe) was smaller (312K vs. 320) than the overall average web page, due in part to the increased used of HTTP compression (89% versus 66%).
