Product hunt launch was definitely a turning point for us (Namify.tech). It got us crazy visibility. Which in turn led to tech experts on social media talking about it. Which increased direct traffic and brand searches. Which in turn boosted SEO too. So definitely Product Hunt FTW π
I'd say all the following ways are best on their own terms.
1) Direct sales - Doesn't take time as SEO or other means of marketing.
2) PH - Helps in getting a heavy influx of traffic and related prospects in a shorter span of time.
3) Affiliate/Influencer marketing - They already have an audience. This means we can reach our prospects faster just with a bit of profit cut from our end.
