What Is the First 50 Words Rule?
The first 50 words rule states that AI systems disproportionately weight the opening paragraph of a web page when deciding what the page is about and whether to cite it. Pages that open with a clear, specific definition are significantly more likely to be cited than pages that open with marketing copy, greetings, or vague introductions.
This happens because AI systems process content sequentially. The opening paragraph sets the context for everything that follows. If the opening is vague, AI has to read much further to understand what the page is about — and may classify it incorrectly or skip it entirely.
The rule applies to every important page on your site: homepage, product pages, pricing pages, blog posts, and documentation. The first 50 words should tell AI exactly what the page is about, who it’s for, and what value it provides.
The Formula for a Citation-Worthy Opening
The Formula
“[Entity] is [what it is] for [who it’s for]. It [what it does] by [how it does it]. [One specific fact that makes it quotable].”

Common Opening Mistakes
These opening patterns actively hurt AI citation rates.
"Welcome to..."
Tells AI nothing about the page's topic. Wastes the most valuable real estate on your page.
Fix: Start with a definition of what the page is about.
"We're passionate about..."
Marketing sentiment that AI can't cite. No factual content to extract.
Fix: Replace with what you do and for whom.
"In today's fast-paced world..."
Generic filler that could apply to any topic. Forces AI to read further to find the actual topic.
Fix: Lead with the specific topic and a concrete fact.
"[Long company history]..."
If your opening is about your founding story instead of what you do, AI won't understand your product.
Fix: Move company history to an About page. Lead with value.
"Click here to get started..."
CTA-first openings give AI no substantive content to evaluate.
Fix: Define what users are getting started with first.
