10 days are gone since launching, and still, no user signed up on my website? How can I gear up?

Check your serpdog . io email. I sent you a note 10 days ago that could potentially be a way to get traction.

As a marketer, I think you should educate people about your tool. Be specific about your niche. You have to try paid ads.

What kind of marketing do you have?
Users won't come by their own. You need to guide them onto your website.

For our startup era.sh (a markdown note-taking tool for developers), we started with Twitter, I posted there for several months to gain an audience for our niche and slowly people come and download our tool.

Beside that try to interact with people who could be potential customers. Not only on Twitter - you can use platforms like Indiehackers, Reddit or HN, too.

Be present everywhere. That will lead to customers.
But don't expect miracles.

Btw. I would add some spacing between the ✅ symbols on your landing page. It looks quite squeezed.

Cheers,
Alex
