In my last post I scanned 106 semiconductor sites and the average score was 42/100 — an F.
Then I ran the same scanner on our own homepage.
29/100. Also an F.
So I spent one afternoon fixing it. We got to 83/100 (A).
Here are the three highest-ROI changes, ranked by effort. All of them are free and most take under an hour.
1. Add markdown content negotiation (15 min)
The single biggest waste: when an AI agent requests Accept: text/markdown, most servers still dump a wall of HTML. A typical chip-company homepage costs an agent 40,000–90,000 tokens to parse. The same content as clean markdown is 1,000–2,500 tokens — a 95% reduction.
If you use a modern framework (Next.js, Astro, SvelteKit, etc.) you can do this in one middleware block:
if ((req.headers.get('accept') || '').includes('text/markdown')) {
return new Response(markdown, {
headers: { 'Content-Type': 'text/markdown; charset=utf-8' }
});
}
Or at the edge (Cloudflare Workers / Vercel Edge):
export default {
async fetch(request) {
const url = new URL(request.url);
if (request.headers.get('accept')?.includes('text/markdown')) {
const md = await getMarkdownForPath(url.pathname);
return new Response(md, {
headers: { 'Content-Type': 'text/markdown' }
});
}
return fetch(request);
}
};
Impact: ~25 point jump on our score.
2. Write an llms.txt (20 min)
llms.txt is a simple markdown index at /.well-known/llms.txt that tells an AI agent which pages matter and what they contain. Think of it as a robots.txt for language models.

## Products
- [Scanner](https://aireadify.ai/scan): Free 0–100 score for any URL, ~2s, no signup
- [Leaderboard](https://aireadify.ai/leaderboard): 106 semiconductor sites ranked
## Content

- [Methodology: 20 signals we check](https://aireadify.ai/blog/methodology)
That's it. No schema, no JSON, no XML. Just markdown links with descriptions.
Impact: ~20 point jump.
3. Add structured data for products (30 min)
Most B2B sites have product catalogs that are invisible to AI agents because they're rendered client-side or buried in unstructured HTML.
Add JSON-LD Product schema to each product page:
{
"@context": "https://schema.org",
"@type": "Product",
"name": "CT8000 3D Hall Sensor",
"description": "±40 mT, I²C / SPI, AEC-Q100 Grade 1",
"sku": "CT8000-WL-TR",
"brand": {
"@type": "Brand",
"name": "YourCompany"
}
}
And expose a simple MCP endpoint so agents can query it directly instead of scraping:
// POST /mcp/search_parts
{
"query": "3D hall sensor I2C automotive"
}
Impact: ~10 point jump.
The full checklist
| Fix | Time | Point gain |
|---|---|---|
| Markdown content negotiation | 15 min | ~25 |
| llms.txt | 20 min | ~20 |
| JSON-LD structured data | 30 min | ~10 |
| robots.txt + sitemap.xml | 10 min | ~5 |
| Open Graph + Twitter Cards | 15 min | ~5 |
| Total | ~90 min | ~65 |
We went from 29 → 83 in roughly that order. The last 17 points are diminishing returns — semantic HTML, dark-mode meta tags, RSS feeds — nice-to-haves.
Why this matters beyond the score
Buyers are researching inside ChatGPT, Claude, and Perplexity now. If your site costs an agent 90k tokens to parse, it gets deprioritized or hallucinated. If it serves clean markdown with an index, it gets cited.
The score is a proxy for "how likely is an AI to recommend you?"
