SaaS start-ups need a website. The majority of your marketing efforts will revolve around your brand website, forming a hub for email campaigns, landing pages, content marketing, and your SEO efforts. This is your most important asset, so creating this is a top priority.
Treat your brand website home page as a landing page for users who are aware of your product. If a visitor lands on your homepage chances are they’ve arrived via organic search or via your sales strategy (different ways you can generate leads for your SaaS).
You can use all the same best practices for a landing page with the exception of navigational links. Use your menu to help visitors dive deeper into your SaaS.
