Introducing Markdown For Agents
Cloudflare, Thursday, February 12th, 2026
The way content and businesses are discovered online is changing rapidly. In the past, traffic originated from traditional search engines, and SEO determined who got found first. Now the traffic is increasingly coming from AI crawlers and agents that demand structured data within the often-unstructured Web that was built for humans.
Why markdown is important
Feeding raw HTML to an AI is like paying by the word to read packaging instead of the letter inside. A simple ## About Us on a page in markdown costs roughly 3 tokens; its HTML equivalent - <h2 class="section-title" id="about">About Us</h2> - burns 12-15, and that's before you account for the <div> wrappers, nav bars, and script tags that pad every real web page and have zero semantic value.
This blog post you're reading takes 16,180 tokens in HTML and 3,150 tokens when converted to markdown. That's a 80% reduction in token usage.
