Based on the excellent feedback I've been receiving here on Indie Hackers (https://www.indiehackers.com/post/latest-landing-page-revamp-thanks-to-your-help-b0a8a27344) I've significantly reworked the NullBox landing page over the past few weeks.
So far, I have done very little marketing for NullBox, primarily just involvement in a few online communities and submitting NullBox to some beta/startup registries. These efforts have been enough to get some early adoption to help validate the product idea and get some valuable user feedback.
However, I haven't wanted to invest a lot of effort or money into marketing if I didn't have a landing page capable of driving product registration. While there's always room for improvement, I feel like the landing page is now in a significantly better place and ready for me to start more actively attempting to increase site traffic.
