Questions
What is the most used of the monitoring tools?

How is market share measured here?
By websites: we read the homepage code of every site in our crawl and count the sites that load each tool. A site that runs two counts for both, so the shares can add up to more than 100%. It's a count of sites, not of revenue or orders.
