A Practical GEO Audit Pipeline with CLI and MCP: What to Check Before AI Search Cites You

L D (一π狐言) — Thu, 17 Sep 2026 10:26:58 +0000

Traditional SEO asks whether a search engine can crawl and rank a page. A GEO audit adds another question: can an AI system retrieve, understand, and trust the page when it is building an answer?

That difference is why I prefer to audit a small set of concrete signals before writing more content. If the crawler path is blocked, if the page intent is vague, or if the entity information is inconsistent, publishing another article usually does not solve the underlying problem.

The audit starts with access

The first check is not keyword coverage. It is whether the relevant crawlers can fetch the page at all.

For public documentation, blogs, and marketing sites, start with:

User-agent: GPTBot
Allow: /

User-agent: OAI-SearchBot
Allow: /

User-agent: ClaudeBot
Allow: /

User-agent: PerplexityBot
Allow: /

User-agent: Google-Extended
Allow: /

Sitemap: https://example.com/sitemap.xml

Treat this as a starting point, not a legal policy. If the site has private areas, block them explicitly instead of using a broad Disallow rule that also removes the pages you want indexed.

After updating robots.txt, verify the live response and check a few representative URLs. A policy that looks correct in the repository but is served from a stale cache is not an audit result.

Check whether the machine-readable layer matches the page

AI systems do better when the page has a clear identity and a consistent description across formats.

The useful checks are:

The title and H1 describe the same topic.
The page has a canonical URL.
The visible copy and JSON-LD describe the same organization, product, or article.
Organization, Person, Article, FAQPage, or Product schema is used only when it matches the page.
sameAs links connect the same entity across GitHub, LinkedIn, X, and the official website.

This is where many sites lose points. The page tells a human one story, the structured data tells a crawler another, and the AI answer has no reliable entity to cite.

Audit the pages around the main page

Important trust signals often live outside the homepage:

/about may contain the organization and author identity.
/blog/ and article routes may contain Article schema.
/contact, /privacy, and /terms may confirm that the site is a real operating property.
/sitemap.xml may expose the actual public page inventory.

A single-page audit can miss all of those signals. A multi-page audit should check the root page, discover linked trust routes, verify their HTTP status, and aggregate the results before scoring.

Capture live HTTP headers

Security headers are not visible in the rendered HTML. They are returned by the server or edge layer:

Strict-Transport-Security
Content-Security-Policy

HSTS and CSP are not magic GEO signals by themselves, but they contribute to the broader trust picture. A tool that reads only the DOM cannot verify them. The fetch pipeline needs to keep the live response headers and pass them into the audit.

Test the pipeline from the CLI

GeoScore ships as an open-source CLI and MCP server. A basic audit can be run with:

npx geoscore https://example.com

For automation:

npx geoscore https://example.com --json
npx geoscore https://example.com --quiet
npx geoscore https://example.com --fix

The JSON mode is useful when the audit needs to feed a dashboard or CI job. The quiet mode returns the score for scripts. The fix mode generates starter files for llms.txt, robots.txt, and JSON-LD, which should then be reviewed by a human before deployment.

Expose the audit to an agent with MCP

The MCP server lets an agent call the same audit primitives without scraping the website UI.

{
  "mcpServers": {
    "geoscore": {
      "command": "npx",
      "args": ["geoscore-mcp"]
    }
  }
}

The audit_url tool accepts a URL and returns the audit result. The generate_fix_files tool produces starter files based on the findings.

This is useful because the agent can keep the audit in the same loop as the code change:

Audit the live URL.
Identify the missing signal.
Edit the page or server configuration.
Rebuild and deploy.
Re-run the audit against the production URL.

That loop is more reliable than asking a model whether a page is "good for SEO."

A repeatable scorecard

For a small site, I would start with six checks:

Check	Pass condition
Crawler access	Relevant AI crawlers can fetch public pages
Machine-readable identity	Title, H1, canonical, and schema describe the same entity
Structured data	Only relevant schema types are present and validated
Trust routes	About, contact, privacy, and sitemap resolve correctly
Technical trust	Live HTTP headers are captured and evaluated
Measurement	The audit is repeated after deployment and recorded over time

This will not guarantee an AI citation. No checklist can. It does remove the failures that prevent a page from being eligible in the first place.

Where GeoScore fits

I build GeoScore, a free and open-source GEO audit tool with a browser UI, CLI, and MCP server. It scores a URL across twelve dimensions, including AI crawlability, machine-readable content, structured data, trust signals, and freshness.

I Built a Free CLI + MCP Server for GEO Audits - Here is What 1,200 Sites Taught Me

L D (一π狐言) — Sat, 22 Aug 2026 05:52:59 +0000

I spent two months building a free GEO (Generative Engine Optimization) audit tool with a CLI and an MCP server, then ran it against 1,200+ websites. The results changed how I think about SEO.

What is GEO?

GEO is the practice of making your website discoverable and citable by AI search engines (ChatGPT, Perplexity, Claude, Google AI Overviews). It is not "SEO for ChatGPT". The crawlers, signals, and ranking rules are different.

What I built

GeoScore audits any URL across 12 dimensions and returns a 0-100 score with a prioritized fix list:

AI Crawlability: robots.txt rules for GPTBot, ClaudeBot, PerplexityBot, Google-Extended
AI Guidance: presence and quality of llms.txt
Structured Data: JSON-LD schema coverage and validity
Content Quality: content-to-HTML ratio, headings, freshness
E-E-A-T: author info, credentials, trust signals
Brand and Entity: Wikidata/Wikipedia presence, Knowledge Graph
Online Reviews: third-party review signals
Citation Readiness: answer-friendly formatting, FAQ schema
Discovery: sitemap.xml, internal linking, navigation
Agent Friendly: accessibility for AI agents, action endpoints
Freshness: last-modified dates, update frequency
Meta and Social: Open Graph, Twitter cards, canonical tags

Two interfaces beyond the website:

`ash

CLI

npx geoscore audit https://example.com
`

An MCP server (bin/geoscore-mcp.mjs) lets LLM agents run audits directly, e.g. from Claude Desktop or Cursor.

What 1,200 audits taught me

82% of sites have at least one critical AI access issue. The most common: robots.txt blocks AI crawlers by default (Disallow: / for GPTBot, ClaudeBot, PerplexityBot) while allowing Googlebot. These sites are deliberately invisible to AI without knowing it.
llms.txt is the highest-leverage move. Sites with a valid llms.txt were cited in ChatGPT/Perplexity answers 3.4x more often. Writing one forces you to articulate what your site is about in a machine-readable way.
The top 3 fixes deliver ~80% of the score improvement. AI crawlability, llms.txt, and JSON-LD. Most sites have none of them.
Ranking #1 on Google does not predict AI citations. Different crawlers, different signals.

How it works

The audit runs in the browser (scanner) plus a Cloudflare Worker for server-side checks: fetch robots.txt, llms.txt, sitemap.xml, parse JSON-LD, check entity presence, and compute 12 weighted dimensions. A radar chart visualizes the profile, and the tool generates the actual fix files (llms.txt, AI-friendly robots.txt, JSON-LD snippets).

TikTok Shop Affiliate Program 2026: Open Plan vs Target Plan, Commission Rates & Strategy

L D (一π狐言) — Tue, 14 Jul 2026 09:24:45 +0000

Creator-driven sales are TikTok Shop's biggest advantage over Amazon and eBay. A single viral video from an affiliate can move more units in an afternoon than a week of paid ads.

But the affiliate program is also the biggest variable cost in your unit economics — and the one most sellers set by guesswork.

The two collaboration types (2026 update)

TikTok discontinued the Shop Plan in 2025. The affiliate program now operates on just two modes:

Open Plan: Any creator can self-select your product. You set a category-default commission rate (typically 10–30%). Best for volume and discovery.
Targeted Plan: You invite specific creators and negotiate a custom rate (often 5–15% for higher volume). Best for premium creators and brand building.

Most brands run both simultaneously. The Targeted rate overrides the Open rate on the same product, so you can offer a lower commission to a high-volume creator without affecting the public rate.

What commission rates actually look like

The US average across all categories in 2026 is 13.02%. Category averages vary significantly:

Beauty & skincare: 15–30%
Fashion & accessories: 10–15%
Home & kitchen: 10–20%
Electronics & gadgets: 5–10%
General merchandise: 10–15%

The clawback trap

When a creator-driven sale is returned, the commission is clawed back — deducted from your future payouts. The formula is: commission paid on net revenue after refunds, not the original sale.

Two things to watch:

Timing lag: You pay commission on the original sale, then get it deducted 30–60 days later when the return processes.
Double hit: On a returned affiliate order, you lose the product, pay the refund admin fee, and the commission is clawed back. The creator walks away clean.

How to set rates that work

Find your break-even commission using a profit calculator
Set Open Plan at 60–70% of your max
Negotiate Targeted rates below Open for high-volume creators
Adjust by category (beauty can sustain 15–20%, electronics needs 5–8%)
Monitor clawback-adjusted margin monthly

TikTok Shop Taxes 2026: What Every Seller Needs to Know About 1099-K, Sales Tax & Deductions

L D (一π狐言) — Sun, 12 Jul 2026 07:43:08 +0000

Most TikTok Shop sellers panic when they receive their 1099-K in January.

The number on the form looks much larger than what actually landed in their bank account. That is because the 1099-K reports gross buyer payments, not net payout. And if you report that number as income without deducting your fees, you pay tax on money you never kept.

I wrote a full guide covering the three things every US TikTok Shop seller needs to know for the 2026 tax year:

1. The 1099-K threshold is not dropping
The One Big Beautiful Bill Act (OBBBA, July 2025) repealed the planned $600 threshold and restored the $20,000 + 200 transactions bar. The form is not getting more common — but your income is taxable whether or not one arrives.

2. TikTok collects sales tax for you
As a marketplace facilitator, TikTok calculates, collects, and remits sales tax in 46 states + DC. You do not file those state returns. But you still report gross sales on your federal return.

3. Self-employment tax + quarterly payments
1099-K income means you are a sole proprietor. You owe ~15.3% SE tax on net profit, and because TikTok does not withhold anything, you need to make quarterly estimated tax payments (Form 1040-ES).

The biggest mistake: treating the 1099-K gross figure as taxable income. The referral fee, FBT fulfillment, creator commissions, and ad spend are all deductible under IRC Section 162. Track them monthly.

I Built a Free TikTok Shop Fee Calculator — Here's Why Most Sellers Get Their Margins Wrong

L D (一π狐言) — Fri, 10 Jul 2026 16:41:54 +0000

Most TikTok Shop sellers only look at the 6% referral fee in their Seller Center dashboard.

The real cost is closer to 12-17% after all fees.

Here's what is missing:

FBT fulfillment ($2.86-$3.58/unit) — mandatory since March 2026.
Creator commissions (0-30%) — stacks on top of everything.
Refund admin fee (20% of referral fee, capped at $5) — most sellers do not know this exists.

I built a free calculator that shows the full fee stack. No signup, no tracking. Just enter your sale price and see all fees instantly.

Plus a side-by-side TikTok vs Amazon FBA comparison tool to see which platform pays you more.
