Scan any domain in 15 seconds. See exactly what's blocking AI crawlers from finding you — and get the fixes.
BoostLLMs is an AI readiness tool that scans any website domain and returns a 0–100 score across six categories that decide whether AI crawlers can read, understand, and surface your content. The free scan runs in about 15 seconds with no account required.
Obsessing over SEO while blocking GPTBot.
Somewhere around late 2024, I started noticing a pattern: companies spending real budget on SEO rankings while their robots.txt was quietly blocking GPTBot. The AI search channel was live and most sites were dark to it — not by design, just by neglect.
People increasingly ask AI assistants for "best tools for X" instead of running a search. If your site isn't structured for AI crawlers, you're not in the answer. No backlink strategy fixes that.
BoostLLMs starts with a free scan — paste a domain, get an AI-readiness score from 0–100 across six categories in about 15 seconds, no signup needed. The score isn't a vanity number: it's built from what blocks or helps AI crawlers.

Why I built it
Two things collided at the same time.
One: I kept seeing companies spending real budget on SEO while their robots.txt was quietly blocking GPTBot. The AI search channel was live and most sites were dark to it — not by design, just by neglect. That felt like a gap worth filling.
Two: I wanted to build a product where the hard part is invisible to the user but the output is meaningfully better because of it. The free scan takes 15 seconds. Getting that right — without asking anything of the user — was the interesting problem to solve.
The product is live. The free scan is genuinely free, no card required.
Built by Felipe Millán — a builder-marketer with over a decade in growth, SEO, and product, including time on the teams at SendGrid, Twilio, and Semrush.
Better up front than in the small print.
Some crawlers see updates later than others
Schema updates are picked up when a crawler renders your pages dynamically. Crawlers that only read static content won't see the latest markup right away. Most major AI crawlers (GPTBot, ClaudeBot, PerplexityBot) handle this — but not all, and not on every crawl.
llms.txt is still an emerging standard
Not all AI crawlers check for it yet. The spec exists, adoption is growing, but it isn't as established as robots.txt. I ship it anyway because early positioning in a new standard tends to matter.
URL credits are consumed on scan + schema generation
A site with 500 URLs that you rescan weekly will burn through credits fast. The pricing page is explicit about this before you hit a billing surprise.
It's a live, improving product
Scoring model, schema generation quality, and crawl depth are all actively being refined. There are rough edges I know about and am working through.

faq
What exactly is an AI readiness score?
It's a 0–100 composite score across six categories — crawler access, sitemap, indexability, metadata quality, structured data, and content depth — based on what blocks or helps AI crawlers read your site. Not a vanity metric: a low structured data score means AI can't extract entities from your pages. A blocked GPTBot means you're invisible to ChatGPT browsing.
What AI crawlers do you check against?
We check 19 known AI crawlers including GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended, Amazonbot, and others. The full list is on the site.
How does the schema update automatically?
Once installed, schema is generated from your existing content and kept current as your pages change. The major AI crawlers — GPTBot, ClaudeBot, PerplexityBot — see updated markup without you touching your site again. The one caveat we're upfront about: not every crawler picks up updates on every crawl.
What's llms.txt and why does it matter?
llms.txt is a proposed standard — analogous to robots.txt — that gives AI crawlers a structured overview of your site: what it is, who it's for, and links to key content. It's not universally supported yet, but early adoption tends to matter when standards emerge. We generate the Overview block, About section, and structured links the spec defines.
How are URL credits consumed?
Credits are consumed on scan and on schema generation. A Pro plan includes 100 URLs. Additional packs are $10/100 URLs. If you rescan a 500-URL site frequently, do the math before committing — the pricing page is explicit about this.
Is the free scan really free?
Yes. Paste a domain, get a score. No signup, no card, no catch. The free plan covers one domain with the Quick Scan permanently. Pro adds full-site scanning, per-page issue codes, schema generation, and llms.txt.
