Hi. We offer SEO as part of the digital marketing services we offer, and I have run multiple SAAS companies, and helped others. However, unless you plan to add a lot of content to your website, SEO is not likely to deliver the results you are hoping for. Changes are it may even lose you money. There are a lot better ways to promote a SAAS company (such as external content marketing, PR, affiliate partnerships, Google Ads) and to get a better return on the efforts (email marketing, retargeting, CRO). Even if you do engage with SEO via a lot more content on the site (not a bad strategy in itself), be prepared for it to be a slow return.
