Marketing tools are priced for companies, which makes the entry points steep and the free tiers unusually restrictive. Keyword research platforms in particular are expensive because the underlying index is expensive to maintain, and there is no honest way around that. What you can do is avoid paying for three tools that overlap. Most teams need one source of search data, one email platform, and one analytics tool; everything beyond that is usually a duplicate with a different dashboard. The listings below highlight where the free tier is actually usable, which tools charge per contact versus per email sent, and which ones have a self-hosted or open-source alternative that removes the bill entirely. For a new site, the honest advice is to spend nothing on marketing tools until you have traffic worth measuring.
