  • Zigpoll alternatives for post-purchase survey attribution

    Zigpoll is a reasonable place to start with post-purchase surveys. It is quick to install, it handles on-site and exit intent surveys alongside post-purchase, and the free Lite tier gives…


  • Tableau alternatives for e-commerce reporting

    Tableau is a serious analytics platform, and for most stores under $20M that is exactly the problem. It assumes you already have clean, modeled data sitting somewhere and an analyst…

About

Six years in e-commerce. Three Shopify stores across different niches, one scaled past seven figures. I’ve tested hundreds of ad creatives, obsessed over email flows, and learned more from my failures than my wins.

Now I focus on conversion optimization, retention marketing, and the analytics behind it all. This blog is where I share what actually works, backed by real numbers. No fluff, no guru energy.
