Potential problems with Google Website Optimizer

GWO.md

• Adds at least 4 new JavaScript scripts to the site.
  • Makes the site load slower.
  • Makes the site be larger, that may be an issue for mobile devices.
• Has some past with Cross-Site Scripting (XSS) attacks
• Doesn't do too good job with dynamically generated data.
  • Needs more setup
  • Needs more custom JavaScript for every case
• A/B testing needs manually create each version of the page, and requires redirect
• For MVT the markup of the section needs to be changed to add the script tags for each and every item that is to be tested.
  • Adds development work
  • Makes it harder to roll out, and to roll back MVT tests.
• GWO affects every user to the site, as the script tags are there for every user.
• Not convinced that it is ready for Enterprise usage.
  • A/B testing is recommended for '''fewer''' then 1000 views a week
