Observer's Performance Suggestions

Priority actions Observer identified from this test to improve speed, reliability, and user experience.

2 images served larger than displayed
Error Medium

2 images are served at intrinsic dimensions more than 120% of their display size. Worst offender is 143% of display size. Resize images to match their rendered dimensions to save bandwidth. Read more

High Total Blocking Time (806 ms)
Warning High

Long JavaScript tasks block the main thread, making the page feel unresponsive. Split long tasks, defer non-critical scripts, and reduce third-party JavaScript. Read more

High Total Blocking Time (638 ms)
Warning High

Long JavaScript tasks block the main thread, making the page feel unresponsive. Split long tasks, defer non-critical scripts, and reduce third-party JavaScript. Read more

2 slow third-party resources
Warning High

2 third-party resources 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=n44gtyj8iwcy at 5405 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

Desktop performance needs improvement (68/100)
Warning Medium

Score is below 90. Tackle the highest-impact audits to push into the green. Read more

Mobile performance needs improvement (69/100)
Warning Medium

Score is below 90. Tackle the highest-impact audits to push into the green. Read more

Slow full page load (12308 ms)
Warning Medium

Browser took longer than 5 seconds to reach DOM complete. Audit blocking resources and backend latency. Read more

8 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

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

Audit Details

Audit Insight Impact
Minify CSS

Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.

  • https://siteobserver.co/wp-content/themes/observer/assets/css/reset.css?ver=1.0.3 Potential savings: 3.59 KB
Est savings of 4 KiB
Network dependency tree

Avoid chaining critical requests by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.

 Open
Forced reflow

A forced reflow occurs when JavaScript queries geometric properties (such as offsetWidth) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about forced reflows and possible mitigations.

 Open
Reduce JavaScript execution time

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to reduce Javascript execution time.
