How this one strategy get me 150+ visitors per day?

I am thrilled to publish my first post on Indie Hackers community...

After getting the approval to post here... I am super excited to announce my first achievement since I built new website from the scratch https://picsenhancer.com

Without implementing basic or advanced SEO strategies, running paid ads, email marketing or posting social media, I am achieving around 150+ users per day on my website globally.

Mostly from USA, India, UK, Brazil and many others.

And that's all come from just on digital strategy which is launching my product on PH (Product Hunt), Twitter, also my website is based on AI model so I'd also listed my site FuturePedia, Theresanaiforthat and many other AI tools listing sites.

This mean only word of mouth, listing site on directory websites and social media can get you most of the traffic in higher competition.

How do I generate the revenue?

Well, currently I am providing photo enhancement services free of cost and earning just from AdSense.

But in future I am willing to implement monthly subscription model to bootstrap my business.

What's your thoughts let me in the comment section.
