Observer's Performance Suggestions
Priority actions Observer identified from this test to improve speed, reliability, and user experience.
|
4 images served larger than displayed
Error
Medium
4 images are served at intrinsic dimensions more than 120% of their display size. Worst offender is 1071% of display size. Resize images to match their rendered dimensions to save bandwidth. Read more |
|
Slow Speed Index (8.4 s)
Warning
High
The page takes too long to visually complete. Optimize critical rendering path, reduce render-blocking resources, and serve visible content first. Read more |
|
Mobile score is 43 points lower than desktop
Warning
High
Desktop scores 100/100 but mobile only 57/100. Optimize for mobile CPU, network and viewport — most real-world traffic is mobile. Read more |
|
1 slow third-party resource
Warning
High
1 third-party resource took longer than 1 second to load. Slowest: https://www.google.com/recaptcha/api2/anchor?ar=1&k=6LcrRNAsAAAAACoZXJ85Kng0wLGEvV6MnS6Qbax8&co=aHR0cHM6Ly9zaXRlb2JzZXJ2ZXIuY286NDQz&hl=en&v=A7KpaEASfhDcK0nXxgQEyyYv&size=invisible&anchor-ms=20000&execute-ms=30000&cb=mv38e3qusyke at 2393 ms. Consider self-hosting critical assets or lazy-loading non-essential ones. Read more |
|
Missing Strict-Transport-Security header
Warning
High
Without HSTS, browsers can be tricked into loading the site over plain HTTP, exposing traffic to interception. Add a Strict-Transport-Security header with a long max-age. Read more |
|
Mobile performance needs improvement (57/100)
Warning
Medium
Score is below 90. Tackle the highest-impact audits to push into the green. Read more |
|
9 render-blocking resources
Warning
Medium
More than 3 resources block initial rendering. Defer or async non-critical scripts and inline critical CSS to speed up first paint. Read more |
|
Third-party scripts are 54% of page weight
Warning
Medium
Most of the page bytes come from third-party scripts. Audit tag managers, analytics, A/B tools and remove ones you no longer use. Read more |
|
No caching headers set
Warning
Medium
The response does not include Cache-Control or Expires headers. Browsers will use heuristic caching, which can serve stale content or skip caching entirely. Set explicit cache directives. Read more |
|
Missing meta description
Warning
Medium
No <meta name="description"> was found. Search engines use this for snippet text in results. Add a concise, relevant description to improve click-through rates. Read more |
