Oh interesting links

Apparently an About page is a flag Google search uses to increase trust rating
on your site. Dunno how much or if it's complete bs but can't hurt.

Comparison pages, your customers are very well educated and most likely have
looked at 4-5 different solutions.

Guide them to why your SaaS may or may not be the best solution for them.

I think FAQ is not enough. Knowledge Base is essential.

Knowledge base in addition to FAQ and support. Extremely important is active
support. We have an app,

The Cloud Tutorial

, this reduces repetitive customer support tickets and is a combination of FAQ,
tutorials, and knowledge base.

Definitely real testimonials (videos are even better) from current clients (or
beta testers) for building trust and credibility, "Solution for" pages, Privacy
Policy (Terms & Conditions), Integrations page if you have some, also "Why *your
product's name*" may come in handy.
