SeaOcean is a web-based SEO audit and AI Search Optimization (GEO) platform used by more than 150 reviewers, running technical on-page checks alongside LLM visibility tracking and automatic llms.txt generation. It tracks whether AI answer engines cite a site at all, not just whether Google ranks it.
About SeaOcean
SeaOcean is a web-based SEO audit platform built for the shift toward AI-powered answer engines. Instead of optimizing only for traditional Google rankings, it treats visibility inside ChatGPT, Claude, and Perplexity as a measurable channel, tracking how often a site's content actually gets cited in AI-generated answers rather than just listed in search results. The platform is aimed at SEO professionals, digital marketers, and small agencies that want AI search optimization bundled with standard technical auditing, instead of running a separate citation-tracking subscription alongside their usual audit tool. It works entirely through the browser, so there is nothing to install before running a first scan.
Pricing
Free tier: basic audits. Pro: $19/month. Agency: $49/month. All tiers web-based with no installation required.
Key Features
- 75+ Parameter SEO Audit: Audits websites across title tags, meta descriptions, Open Graph, JSON-LD, sitemaps, and Core Web Vitals with instant reports and AI-powered fix recommendations.
- AI Search Optimization (GEO): Provides tools specifically for optimizing content visibility in AI-powered answer engines like ChatGPT, Claude, and Perplexity, beyond traditional search engine rankings.
- LLM Visibility Tracking: Monitors how frequently the site appears in AI-generated answers and analyzes which content receives citations from large language model systems.
- llms.txt Auto-Generation: Automatically generates llms.txt files that signal to AI crawlers how to index and cite site content, using a format designed for AI search engine compliance.
- Weekly Monitoring with Email Alerts: Runs automated weekly SEO checks and sends email alerts on changes, covering keyword tracking and competitor comparison without manual re-auditing.
Pros
- Bundles standard technical SEO auditing with dedicated AI Search Optimization (GEO) tools in one dashboard, so teams do not need a separate subscription just to monitor visibility in ChatGPT, Claude, and Perplexity.
- Automatically generates and maintains an llms.txt file, handling a newer AI-crawler standard that most mainstream audit tools do not yet support natively.
- Free tier covers basic audits, giving smaller sites a way to try the technical checks with no cost or card required.
Cons
- Does not publish a developer API as of 2026, so teams that need programmatic access to audit or citation data have to work through the web dashboard manually.
- LLM visibility tracking depends on how often AI crawlers actually index a site, so the data can lag noticeably for lower-traffic or newly launched websites.
- Has limited public brand recognition compared to established SEO suites, so there are fewer independent tutorials or third-party integration guides available.
Frequently Asked Questions
What does SeaOcean actually cost?
SeaOcean has three tiers: Free for basic audits, Pro at $19 a month, and Agency at $49 a month for teams managing multiple client sites. All three run entirely in the browser, so there is no separate software to install.
Does SeaOcean have a free plan?
Yes, the free tier covers basic technical SEO audits with no time limit. The GEO tools, including LLM visibility tracking and llms.txt generation, along with weekly monitoring and email alerts, require the Pro or Agency plan.
What are SeaOcean's closest competitors?
CiteLens is a closer match for teams that only need multi-LLM citation tracking, running from a free plan up to $1,499 a month for its Agency tier. NEURONwriter fits better if the priority is AI-assisted content writing and semantic SEO scoring rather than technical audits, starting near the same price point as SeaOcean's own Pro tier.
Is SeaOcean better than CiteLens?
CiteLens focuses only on tracking brand and site citations across ChatGPT, Perplexity, Claude, and Gemini, with pricing that scales up to $1,499 a month for high-volume enterprise monitoring. SeaOcean instead bundles that same AI-citation tracking with a full technical SEO audit in one lower-cost plan, so smaller teams get both jobs without paying for two separate tools.
How long does it take to get going with SeaOcean?
One sign-up and one scan is all it takes: create a free account at seaocean.io, no installation or credit card required, then point the audit at your site's URL and the results come back in that same session. Upgrading to Pro or Agency for GEO tracking or multi-site monitoring can happen later, straight from the dashboard.
Top Alternatives
- CiteLens: Dedicated multi-LLM citation tracking at enterprise scale is CiteLens's specialty, running up to $1,499/month for it. SeaOcean folds that same AI-citation tracking into a full technical SEO audit at a lower price point instead, one tool covering both jobs.
- NEURONwriter: NEURONwriter is built for drafting new pages with semantic writing assistance. SeaOcean instead audits pages you've already published and tracks how AI engines cite them, a different stage of the same content pipeline.
