Ahrefs Lite is $129/mo. OCCS SEO Research ships on the Free tier.
OCCS SEO Research seeds keyword candidates from a topic, scores each by intent + difficulty, and generates content briefs you can hand to Blog Studio. Ahrefs is the gold standard for backlink-driven SEO, but if your work is keyword research + content brief generation, the $129 floor is paying for surfaces you'll touch monthly at best.
OCCS
SEO Research is included on every plan including Free. Keyword seeding and SERP teardown are unlimited (subject to your AI budget for each generation). Content briefs export straight into Blog Studio's scaffolder.
