# The results of my PostHog AB Test are in!

In this video from my Tiny Improvements series, I'm diving into product analytics to improve newsletter signups on my personal site. Join me as I share my engineering process, from discovering a bug with my old provider to setting up an A/B test with PostHog to find the best-performing newsletter signup form. Despite fewer-than-hoped signups, I've gathered key insights to refine my strategy. Plus, a sneak peek into my next steps, like redesigning the signup popup and enhancing site SEO. If you're a startup founder or indie hacker, you’ll find plenty of actionable tips here!
