Semrush starts at $139/mo. OCCS tracks 5 keywords for free, forever.
Rank Tracker in OCCS checks Google daily, stores the top 10 plus your position, and surfaces decay + theft alerts. Semrush bundles rank tracking with a dozen other tools — backlink analysis, content audits, position tracking, the works — and prices accordingly. If rank tracking is most of what you need, OCCS gets you 80% of the value at 0% of the price on the Free tier.

Semrush's value compounds when you actually use the rest of the toolkit (audits, backlinks, content briefs). If you only need rank tracking, the floor price is paying for surfaces you ignore. OCCS Free is genuinely free for 5 keywords; Scale matches Semrush Pro's keyword count at $249/mo with the rest of the OCCS platform included.
