Open SEO - Okay, we can talk about it now
Let's start with a hard truth
SEO can easily take a year to get any results.
Even if you do everything right, you can get nothing out of it.
Doing SEO well takes up an enormous amount of resources.
Any SEO hacks you do to overcome the above can get you banned from Google.
All this to say: SEO is REALLY hard, will take up all of your time and could get you nothing. Which is why I am about to go over a ton of research you need to do before you even begin.
You are going to spend 500+ hours on SEO, you need that time put in just the right place, or it will be wasted.
An important question
With everything, I just described, is SEO worth your time as a startup? Can you focus somewhere else and do SEO later?
The answer is... sort of?
When done right, it can lead to incredible growth for a company. It's also technically "free" in that you can do it without spending any money. Instead, it uses your time.
What I generally recommend to my clients is to do SEO in separate parts.
