Findings with evidence

Improve2 H1 headings

<h1>Validate everything. Assume nothing.</h1>
<h1>4x faster test runs</h1>

Fix: Use one <h1> that states the main topic of the page.

ImproveServer responded in 1010 ms

Time to response headers from our checker. Final URL: https://circleci.com/

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

ImproveHTML size 585 KB, 25 script tags

3 render-blocking scripts in <head>: https://d2qm0z2kzhiwa.cloudfront.net/assets/node_modules/algoliasearch/dist/lite/builds/browser.umd…

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