Factual, an “open data repository” analyzed 4 million websites via data from Common Crawl, a non-profit group designed to crawl the web and provide data for anyone to use. Check out the stats below.
*28% of sites have Google Analytics
*5% of sites link to their Twitter or Facebook profile
*2% of sites display both a Twitter and Facebook link
Danny Sullivan, a search engine expert analyzed another chart by Factual that showed additional stats but without exact percentages. After reviewing the charts he estimated about:
*20% of sites use Flash
*19% of sites have an RSS feed
*6% of sites show a sitemap file
*1% of sites have Quantcast tracking code
*0.5% of sites have a Creative Commons attribution
It would be fascinating to see a similar study done for nonprofit organizational websites and compare how nonprofits data measures up to the data from the 4 million random sites that were selected for this study.
