Ask HN: How important is website SEO for a mobile app-only marketplace?

We have a decent marketing website explaining what we do and how it works. We also post blogs on the site once in a while.

But, so far we haven't focussed on SEO at all as the website hasn't been our primary focus and also as SEO is not easy (?) and not our strength.

Almost all our ads take the user directly to the App Store/ Play Store.

Ultimately, to gain organic traffic, SEO is key. So, is it better to invest on it sooner rather than later?
