I gave this presentation at the 2015 SLC|SEM Digital Marketing Conference. I'm always grateful to have the opportunity to speak at conferences and the folks who run SLC|SEM are great people.

The deck outlines some of the biggest mistakes I felt I made/contributed to, during the recent replatforming project that has consumed me for the past year.


  1. No Dedicated QA or stable staging environment
  2. Performance / load testing was not performed on checkout
  3. Marketing team didn't have a good understanding of the new promotions engine
  4. Didn't obsess over old external and internal links
  5. Didn't understand the SEO impact when switching from http to https
