What helps me is to flip the traditional script. The question isn't: "How do I get more attention?" The question is:

"How can I help more people?"

Think about who you aim to serve, where they are, what problems they have, and how you can solve them.

You ask how can you drive attention to a web scraping service. My question would be, how does that web scraping service help them?

And if what you build doesn't provide value to others, all the growth hacks in the world aren't going to help you.
