Serpstat starts at $50/month (around £40) for a full SEO suite that, as of 2026, also includes AI-powered content brief generation and article drafting. Illumae is £40/month per domain with a fact-consistency audit and direct CMS publishing built into its content pipeline.
Serpstat is a full-featured SEO suite — rank tracking across 230 regions, a technical site audit, backlink analysis with lost/new link tracking, and keyword research — that has pushed heavily into AI in 2026, adding content brief generation, article drafting, and an LLM brand-monitoring tool tracking how AI models describe your brand. It's a genuine, direct competitor on the content side, not just SEO fundamentals.
Illumae also includes AI content generation, but built as a fuller publishing pipeline: every draft runs through a fact-consistency audit before publishing and can be pushed directly to your CMS. Both tools compete more directly here than most Illumae comparisons — what follows is an honest breakdown of where each genuinely fits.

Comparison based on publicly available Serpstat pricing and feature information as of 2026. Serpstat pricing is billed in USD; GBP figures are approximate.
Serpstat's Individual plan is $50/month (roughly £40) on annual billing, covering 5 projects, 100 daily searches, and up to 30,000 audited pages/month, with AI content and brand-monitoring tools now included rather than a separate add-on.
Illumae is £40/month per domain, a near-identical entry price. The practical difference is depth of the content pipeline (Illumae's fact-consistency audit and direct publishing versus Serpstat's brief-and-draft tools) versus breadth of AI brand-monitoring (Serpstat's LLM tracking versus Illumae's lack of one).
Serpstat's rank tracking scale (230 regions, unlimited competitor monitoring per project) and its AI-model brand monitoring — tracking how ChatGPT, Claude, and other models describe your brand across real prompts — go further than anything Illumae currently offers. If tracking brand visibility inside AI chat responses specifically matters, Serpstat has a purpose-built tool for it.
Illumae's content pipeline goes further on the publishing side specifically: every article runs through a fact-consistency audit and can be pushed directly to your CMS, rather than producing a brief or draft you still review and publish yourself.
You can add your existing tracked keywords directly into Illumae's Keyword Research tool, and connect Google Search Console in a couple of clicks to bring in your real performance data immediately. Most users are fully set up within 15-20 minutes.
Yes — Serpstat added AI-powered content briefs and article drafting in 2026, a genuine, real feature, not something Illumae uniquely offers. The difference is depth of pipeline: Illumae runs every draft through a fact-consistency audit and can publish directly to your CMS.
No — Illumae doesn't currently offer AI-model brand monitoring. Serpstat's LLM Brand Monitor is a dedicated feature for this that Illumae doesn't have an equivalent for.
They're close — Serpstat's Individual plan is around £40/month on annual billing versus Illumae's £40/month per domain, with no annual commitment required. Which is actually cheaper depends on your billing preference and how many domains you're managing.
Yes. Illumae is priced per domain at £40/month each, with no per-seat charges — an agency managing 3 client sites pays £120/month total, each domain getting its own full toolset.
Yes. Illumae offers a free plan that includes 3 AI article generations, keyword research tools, a content calendar, and a basic dashboard. No credit card is required to sign up.
