My product isn't yet at a point where it has a market fit but I came up with a small excel file that goes in the same direction as my product. I can offer that for free and it starts to pull in organic traffic from google, bing and other places like forums where I suggest my free tool as a solution for someone's problem. My tip for most SaaS out there: If your "keyword + excel/pdf/template" is an easy target, then think about creating a free sub-product with a decent landing-page for it.
