Findings

high Readability without JavaScript

Very little text on the page for either humans or machines

Evidence: 241 words of body text after rendering.
Why it costs citations: Assistants need extractable prose to quote. A page that is mostly imagery and headings gives them nothing to lift, so a competitor with written detail wins the mention.
Fix: Add 400+ words that answer the questions buyers actually ask: what you do, who for, where, what it costs, how to start.

high Machine-readable structure

No Organization / LocalBusiness structured data

Evidence: No JSON-LD found in the raw HTML.
Why it costs citations: This is the block that tells an assistant the entity name, what kind of business it is, where it operates and how to contact it. Without it the assistant has to guess from prose, and it frequently guesses a competitor with clearer markup.
Fix: Add a server-rendered JSON-LD Organization (or LocalBusiness for a physical location) with name, url, logo, description, telephone, address, sameAs links to your profiles, and areaServed.

high Answer-readiness

No headings are phrased as questions people actually ask

Evidence: 1 headings, none in question form.
Why it costs citations: Assistants retrieve by matching a user question to a passage. A heading that restates the question, followed immediately by a direct answer, is the highest-probability shape for being lifted and cited.
Fix: Convert or add headings like "How much does X cost in <city>?", "How long does X take?", "Do you offer X on weekends?" — each followed by a 2–3 sentence direct answer.

high Answer-readiness

No machine-readable way to contact the business

Evidence: tel: links 0, mailto/emails 0, WhatsApp links 0. Phone-shaped strings in text: 2605.
Why it costs citations: When an assistant recommends a business, the next thing it tries to supply is how to reach it. A phone number that exists only inside an image or a JS widget cannot be handed to the customer, so the recommendation goes to whoever published a plain tel: link.
Fix: Add <a href="tel:+91…">, a mailto: link, and a wa.me click-to-chat link in the server-rendered HTML, plus telephone/email in your Organization schema.

medium Machine-readable structure

No FAQPage structured data

Evidence: No FAQPage / Question markup in the raw HTML.
Why it costs citations: Question-and-answer markup is the format answer engines lift most directly, because each answer is already a self-contained, attributable unit.
Fix: Publish 6–10 real customer questions with short direct answers, marked up as FAQPage, rendered server-side.

medium Answer-readiness

No lists or tables in the raw HTML

Evidence: 4 paragraphs, 0 lists, 0 tables.
Why it costs citations: Lists and tables are the easiest structures for an assistant to extract cleanly and reproduce — pricing tiers, service areas, timings, inclusions.
Fix: Convert dense prose about pricing, coverage and process into <ul> and <table> markup.

low Machine-readable structure

No BreadcrumbList structured data

Evidence: Not found in raw HTML.
Why it costs citations: Breadcrumbs help a retrieval system understand where a page sits in the site hierarchy, which improves how it is described when cited.
Fix: Add BreadcrumbList JSON-LD on inner pages.

low Answer-readiness

No machine-readable dates on the page

Evidence: No <time datetime> elements and no dated schema.
Why it costs citations: Assistants prefer sources they can date, and prefer recent ones when a question is time-sensitive.
Fix: Add <time datetime="YYYY-MM-DD"> for published/updated, and datePublished/dateModified in schema.

pass Crawler access

All major answer-engine crawlers are allowed

Evidence: OAI-SearchBot, Claude-SearchBot, PerplexityBot, Googlebot, bingbot, Applebot, Amazonbot, DuckAssistBot, YouBot
Why it costs citations: Nothing in robots.txt stands between the site and AI citations.

pass Crawler access

llms.txt is published

Evidence: 15010 bytes at /llms.txt.
Why it costs citations: An emerging, not-yet-universally-consumed convention. Harmless and occasionally useful; do not expect ranking effects.

pass Readability without JavaScript

Content is present in the raw HTML

Evidence: Raw HTML carries 241 of 241 rendered words (100%).
Why it costs citations: AI crawlers receive substantially the same content a human sees. This is the single biggest thing most sites get wrong, and it is right here.

pass Technical foundations

Sitemap found with 1651 URLs

Evidence: https://nodejs.org/sitemap.xml
Why it costs citations: Crawlers can enumerate your pages.
