Dotcom-Monitor recently chose 20 midsized online companies to monitor for one week from those ranked 500-600 in the Internet Retailer 2011 ranking. We focused our monitoring on a demographic that encompasses what is considered a mid-size company, not large enough to have inexhaustible budgets, and just large enough to begin considering ways to optimize web site performance. By testing their websites at a 15-minute frequency from nine North American monitoring locations for seven days using a non-caching, Internet Explorer browser we were able to pinpoint potential areas to improve and issues to avoid.
