What makes a website AI-readable in the first place
Five things decide whether AI engines can read, understand, and eventually act on your website:
- Raw HTML rendering. GPTBot, ClaudeBot and PerplexityBot mostly don't execute JavaScript. If your content only appears after scripts run, they see nothing.
- Schema support. Can you add LocalBusiness, FAQ and Service markup, page by page, without fighting the platform?
- Root-file control. Can you host llms.txt and control robots.txt for AI crawler access?
- Clean semantic markup. Proper headings and readable structure, not div soup, so machines can parse what's an answer and what's decoration.
- Agent readiness. The emerging one: as AI assistants start acting for users (filling enquiry forms, booking jobs), simple standard forms and clear contact paths beat clever custom widgets.
How the platforms compare
Webflow: strong. Server-rendered HTML by default, so AI crawlers see everything. Per-page schema fields and custom code support, and, as of this year, a native llms.txt upload in site settings. Clean markup if the site is built well. This is what we build client sites on, and the AI-readability is a large part of why.
WordPress: strong, with conditions. Classic themes render server-side and take schema plugins happily; root access means llms.txt is trivial. The conditions: page-builder themes bloated with scripts, or headless setups rendering client-side, can undo all of it. WordPress is as AI-ready as its build quality.
Squarespace: workable. Server-rendered and structurally clean, with basic automatic schema. Limits: custom per-page schema requires code-block workarounds and there's no native root-file hosting for llms.txt.
Wix: improved, but constrained. Rendering has improved markedly and Google indexes it fine. The constraints are control: schema beyond the built-ins is fiddly, root files aren't natively yours, and the generated markup is heavy, machines can read it, but you can't shape what they read with much precision.
DIY site-in-an-app builders (the newest wave): check before you commit. Some AI-era site builders ironically ship JavaScript-only sites that AI crawlers cannot read. The test below takes two minutes and settles it.
The two-minute test for any website
Open your site, then view the page source (not inspect element, the raw source). Search for your phone number and a sentence from your homepage. If they're in the source, AI crawlers can read you. If the source is a near-empty shell of scripts, they can't. Then try yourdomain.com/llms.txt and yourdomain.com/robots.txt to see what you control.
Does this mean you need to rebuild?
Not necessarily. If your platform passes the raw-HTML test, you can usually add the AEO layer, schema, FAQ content, llms.txt where supported, without moving. A rebuild becomes worth it when the platform fails the readability test outright, or when every schema and content change requires a workaround. If you're choosing a platform for a new site today, make AI-readability a selection criterion, it costs nothing to choose well now and plenty to migrate later.
We build AEO-ready sites on Webflow, from $1,495 for tradies, with schema, direct-answer content and llms.txt included, and we can audit whatever you're on now: get a free review.
