SEO Nerve: full site audit in a minute - free score, report from $5
SEO audits today are inconvenient. Semrush asks $129/month, Ahrefs - $99. Ordering an audit from an agency means $500+ and several business days of waiting. And free checkers dump a hundred problems without priorities: fix whatever you want.
We got tired of it. We regularly check sites - our own and clients’ - and subscriptions costing hundreds of dollars a month don’t pay off here. So we built a tool for our own pain and opened it to everyone. That’s how SEO Nerve was born.
How it works
You enter a URL. In a minute or two (mobile Lighthouse takes the longest) you get the overall site score, five directional ratings, and more than thirty sections with specifics. No registration, no account, no email - just a link and a report.
One score at the top so you immediately understand the scale. For example, 76 out of 100. It’s not pulled from thin air: it’s a weighted aggregation where basic SEO checks account for 55%, AI agent readiness - 15%, Lighthouse speed - 20%, and accessibility - 10%. Under the main score are five ratings, each covering its own zone:
- AI visibility - whether ChatGPT, Perplexity, and Claude can see you
- E-E-A-T - whether Google trusts you: author, date, contacts, organization schema
- Agent-Ready - 18 readiness checks for AI agents and crawlers
- Performance - Lighthouse mobile: LCP, FCP, CLS and other metrics
- Accessibility - contrast, ARIA, alt tags, navigation
These are concrete numbers, not “the site seems fine.”
What we check that others don’t
Classic SEO audits look at title, meta tags, and links. We added what will be decisive in 2026-2027 - site readiness for AI search. And this isn’t marketing wrapping, it’s real requests and parsing.
The Agent-Ready section runs 18 checks that neither Semrush nor Ahrefs have. Is there a llms.txt file. Does robots.txt allow by name GPTBot, ClaudeBot, PerplexityBot, Google-Extended and others (at least three needed). Does the site return markdown when asked with an Accept: text/markdown header. Is there an MCP Server Card, API Catalog, OAuth-discovery for agents. This score essentially predicts how much the site will be cited by AI systems as search fully shifts their way.
The second block others miss is AI visibility and E-E-A-T. For AI visibility, the engine counts 11 signals: structured data, FAQ markup, tables and lists, whether author and date are specified, whether robots blocks AI bots, whether there are unique data and quotes. For E-E-A-T - 14 signals: About and Contact pages, physical address, phone, email, privacy and terms, links to authoritative sources, Organization schema. Google accounts for this already, AI systems - even more so.
Not a bug list, but ready-to-use code
Most checkers show a problem and leave you with it. We went further: in the full tier, the report provides ready snippets. Need to close security gaps - here’s the nginx config, copy and paste. Need to allow AI bots - here are the lines for robots.txt. Not “fix the headers,” but a ready piece of code.
The logic is simple: copy, paste, recheck. Or hand it to a developer with exact instructions, no lengthy explanations.
Pricing
Three tiers, all one-time payments. No subscriptions, no contracts.
Free at $0 shows the final score, five ratings, Google site preview, and basic page information. Basic at $5 opens full problem lists with recommendations, all 18 Agent-Ready checks, Lighthouse details, security headers, and a report in PDF and Markdown. Full at $7 adds fixes with ready-to-use code, AI visibility and E-E-A-T details, crawling up to five internal pages with duplicate checks, top keywords, and the site’s technology stack.
Card payment. Currently accepting payments from these countries: Kazakhstan, Azerbaijan, Tajikistan, Ukraine, Uzbekistan, Turkmenistan, Kyrgyzstan, Armenia, Belarus, Georgia, Moldova, and China. The report doesn’t expire and is accessible via a direct link.
Why this matters for an agency or freelancer
One of the most common scenarios is a cold pitch to a client. You found a potential customer, ran their site for $5, got a PDF with thirty sections and specific problems. Then you write: “You have these 12 issues, we’ll fix them for X.” The client sees numbers and ready recommendations instead of vague words. Lead cost - $5, average deal - hundreds of dollars.
Under the hood
SEO Nerve runs on our server: Python and FastAPI, Lighthouse through a separate renderer, Google PageSpeed Insights, Firecrawl for clean markdown. AI comments are generated by the latest Claude and OpenAI models - we keep the engine on current versions, so analysis is always from the latest generation of AI. The report is available in three languages (Russian, English, Ukrainian) and three formats: web, PDF, and Markdown for GitHub or Jira. Audits are cached for 30 minutes so the paid report and PDF show the same numbers. Self-hosted, no vendor lock-in.
This is our product from start to finish - from architecture to deployment. This is exactly how we build client systems too: a content factory that produces articles and posts on its own, or an AI secretary that handles business administration by voice.
