A quick test: view the page source, or fetch it with `curl`, and check that the key text is there. ## Raw HTML vs script-injected text, run I ran this. A text extractor that ignores scripts sees the heading and the paragraph but not the pricing line that JavaScript adds later, so `Pricing` is not found. ```python from html.parser import HTMLParser html_raw = ("<html><body><h1>Acme Tasks</h1><p>Simple boards for small teams.</p>" "<div id='app'></div><script>document.getElementById('app')" ".innerHTML='<p>Pricing from 5 USD</p>'</script></body></html>") class Txt(HTMLParser): def __init__(s): super().__init__(); s.t = []; s.skip = False def handle_starttag(s, tag, a): s.skip = tag in ("script", "style") def handle_endtag(s, tag): s.skip = False def handle_data(s, d): if not s.skip and d.strip(): s.t.append(d.strip()) p = Txt(); p.feed(html_raw) print(p.t, "Pricing" in " ".join(p.t)) ``` Output: ``` ['Acme Tasks', 'Simple boards for small teams.'] False ``` ## Check with curl Run `curl -s https://your-site/pricing | grep -i "5 USD"`.

# Readable HTML Without JavaScript — AI Visibility and LLM Brand Discovery Source: https://www.geekswithgeeks.com/en/ai-visibility/tech-renderable-html > Make sure your key content exists in the raw HTML, not only after scripts run. ## What a simple crawler sees Many AI crawlers fetch the page's HTML and **do not execute JavaScript**. If your pricing, product details or articles are injected by client-side scripts, those crawlers may see an empty shell. Prefer **server-side rendering** or **static generation** for important content, give each page a unique URL, a clear ``, headings and descriptive text, and avoid hiding key facts in images or only in interactive widgets.
