I am currently working on Labour.Quest (https://labour.quest/), a service that allows professionals to host & share their resume using custom themes (sort of like Tumblr).
I am trying to get my wait-list to a decent number of contacts to no with very mediocre success.
I have tried Product Hunt & Beta List. These however, have not moved the by needle much.
Indie Hackers is a bit arbitrary on how one can be able to post their project there.
1. What strategies do you recommend I try?
2. What have you used that has ever worked for you?
3. Basically, what is the most effective way for me to get a decent number of sign-ups for the wait-list?
You could pay for topical google ads to drive people to a landing page?
You could do outreach to professional communities that you feel might benefit from it. Given your description, I could see this being useful to freelance webdevs and designers.
You could write a few months of content around this topic and build some SEO.
