SEO & Content Marketing
SEO and content tools research what an audience searches for, guide how a page should be written to rank for it, and track where that page lands over time.
Organic search is the compounding channel: expensive to start, nearly free at scale, and the reason content marketing survives every budget cut. The category has been reshaped twice recently, first by AI writing and now by AI answers that summarize pages instead of sending clicks. The tools worth tracking for a startup are the focused ones that answer a specific question well without the five-figure annual commitment the suites ask for.
