Findings with evidence

ImproveJSON-LD: 2 blocks, types WebPage, ImageObject, Person, Organization, WebSite, Corporation, SearchAction

WebPage is missing recommended name. Person is missing recommended url. Organization is missing recommended url, sameAs.

Fix: Fix the listed properties, then retest at validator.schema.org.

FixServer responded in 2149 ms

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

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

ImproveHTML size 424 KB, 51 script tags

2 render-blocking scripts in <head>: https://www.heroku.com/wp-includes/js/jquery/jquery.min.js?ver=3.7.1

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