Pricing
OnyxRank starts at $2,997/mo for the Growth retainer (8 articles, 100 keywords, technical SEO, GEO program, monthly reporting). Pro is $5,997/mo and Enterprise is $14,997/mo. Strategy Sprint is a one-off $597 engagement for teams that want a deep audit without a retainer.
ContentKing is a real-time seo monitoring priced from $170/mo ($170 to $700+/mo SaaS). It is software, not a team, and it does not produce articles or run outreach campaigns for you.

Ideal user
ContentKing is the right pick if you fit this profile: An enterprise SEO team that needs instant alerts on site changes.
OnyxRank is the right pick if you want the strategy, content production, technical SEO execution, GEO work, and revenue-attributed reporting delivered as a single managed engagement. We work best with B2B SaaS, ecommerce brands past initial PMF, professional services, and enterprise teams that need execution capacity.
Verdict
ContentKing solves a tool problem; OnyxRank solves an outcome problem. If you already have a senior in-house SEO team, ContentKing can amplify them. If you want SEO + GEO outcomes shipped end-to-end without staffing the function in-house, OnyxRank is the better fit.
Most clients land on a hybrid: they keep one or two best-of-breed tools in-house (Ahrefs, Search Console, Surfer) and hire OnyxRank to operate the program around them.
FAQs
Is OnyxRank a ContentKing alternative?
Not directly. ContentKing tells you what is wrong in real time. OnyxRank operates the team that fixes it. The two pair well together at enterprise scale.
Do you offer real-time monitoring?
We run weekly audits with alerting for critical regressions. For sub-hour monitoring, ContentKing or Conductor is the right tool.
Can I integrate ContentKing with OnyxRank?
Yes, we accept ContentKing alerts into our ops queue and ship fixes on the same cycle.
Do small businesses need ContentKing?
Usually not. Sub-hour monitoring is overkill for sub-100k-page sites. A weekly audit cycle from an agency catches almost everything.
