What is everyone doing for SEO and discoverability?

Heya reddit,

I recently started my SaaS in January and it's been doing really good so far with 600 signups but I'm struggling a little with getting more people to find me. Some days it's like a wave of people and other days I average around 3-5 signups per day.

What are some of you guys with proven results doing? Do I need to hire someone for content/blogs? Or should I just work on improving my existing content?

I run a fintech SaaS if that helps.
