Findings with evidence

FixNo 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.

FixNo JSON-LD structured data on the homepage

No <script type="application/ld+json"> block in the HTML we received.

Fix: Add an Organization (or LocalBusiness) JSON-LD block to the homepage with name, url, logo, and sameAs links. The $19 report includes a ready-to-paste block for your site.

FixServer responded in 2239 ms

Time to response headers from our checker, after 1 redirect. Final URL: https://www.grammarly.com/

Fix: Slow responses can make crawlers give up. Add page caching or a CDN in front of the homepage.

ImproveHTML size 538 KB, 36 script tags

0 render-blocking scripts in <head>

Fix: Large HTML slows crawlers and tools with size limits. Move inline data and scripts out of the HTML.
