Most common problems in website builders
Each count is the number of homepages in this group with that finding on 2026-10-18. The example shows the evidence our checker saved for one of them.
No llms.txt, or one with gaps: 13 of 18 sites
Example from carrd.co (55/100): No llms.txt
GET /llms.txt returned 404.
Fix: Create /llms.txt: a # title, a > one-line summary, then ## sections that list key pages as [name](url). Draft one free at checkaiready.com/llms-txt-generator.
JSON-LD schema missing or with errors: 12 of 18 sites
Example from bubble.io (65/100): JSON-LD: 2 blocks, types Website, Organization
Organization is missing recommended url.
Fix: Fix the listed properties, then retest at validator.schema.org.
Heavy homepage HTML or render-blocking scripts: 12 of 18 sites
Example from typedream.com (65/100): HTML size 467 KB, 38 script tags
2 render-blocking scripts in <head>: https://cdn.jsdelivr.net/npm/[email protected]/dist/algoliasearch-lite.umd.js
Fix: Large HTML slows crawlers and tools with size limits. Move inline data and scripts out of the HTML.
Title missing or too long: 5 of 18 sites
Example from weebly.com (85/100): Title, 67 characters
<title>Free Website Builder: Build a Free Website or Online Store | Weebly</title>
Fix: Shorten to about 50 to 60 characters so tools do not cut it off.
No single clear H1: 3 of 18 sites
Example from duda.co (100/100): 0 H1 headings
No <h1> in the HTML we received.
Fix: Use one <h1> that states the main topic of the page.
Open Graph tags missing: 3 of 18 sites
Example from umso.com (65/100): Open Graph: missing og:description
og:title: Umso - The Website Builder For Everyone og:description: missing og:image: https://umsousercontent.com/lib_yOXSJtLTwZkVZaGZ/ztsyknqqqzfozqva.png?w=1200&h=630&fit=cr…
Fix: Add <meta property="og:description" content="...">. Chat apps and AI tools use these for link previews.
