Findings with evidence

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.

ImproveMeta description, 173 characters

content="Boost productivity and save time with Slack‌ — ‌the AI work platform for managing projects, automating workflows, and connecting teams securely. Start working smarter today."

Fix: Trim to about 160 characters.

ImproveServer responded in 1095 ms

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

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

ImproveHTML size 248 KB, 30 script tags

4 render-blocking scripts in <head>: https://a.slack-edge.com/bv1-13-br/manifest.aeb38c93e342b3e4.marketing.min.js

Fix: Add defer or async to scripts in <head> that are not needed for first paint.
