FixNo JSON-LD structured data on the homepage
No <script type="application/ld+json"> block in the HTML we received.

ImproveTitle, 67 characters
<title>Spline - 3D Design tool in the browser with real-time collaboration</title>
Fix: Shorten to about 50 to 60 characters so tools do not cut it off.
ImproveServer responded in 970 ms
