What you get on the free tier
Free tiers usually include limited daily keyword lookups, basic SERP analysis, a few content optimization scores per month, and access to one or two key features. Enough for solo bloggers and side-project SEO.
When it is worth upgrading
Upgrade when keyword research volume exceeds the free quota, when you need backlink data, when team rank tracking matters, or when content calendar scale demands unlimited optimization scores.
