Observer's Performance Suggestions
Priority actions Observer identified from this test to improve speed, reliability, and user experience.
Missing clickjacking protection
Error
High The page has neither an X-Frame-Options header nor a CSP frame-ancestors directive, so it can be embedded in an iframe on any site, making it vulnerable to clickjacking attacks. Read more |
33 images served larger than displayed
Error
Medium 33 images are served at intrinsic dimensions more than 120% of their display size. Worst offender is 544% of display size. Resize images to match their rendered dimensions to save bandwidth. Read more |
No H1 element found
Error
Low The page is missing an <h1> tag. An H1 heading helps search engines and screen readers understand the primary topic of the page. Read more |
Slow Speed Index (10.3 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 |
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=6LffARgqAAAAAMrtea24k6x63pDXE4vT_WBp_IJn&co=aHR0cHM6Ly93d3cuY2VyZWJyYS5jb20udHI6NDQz&hl=en&v=Br0hYqpfWeFzYCAXLD4UuCIV&size=invisible&anchor-ms=20000&execute-ms=30000&cb=gxwyjl2h4cox at 2246 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 |
Slow server response (1058 ms)
Warning
Medium Server took 1.058 seconds to respond. Investigate backend latency or upstream timeouts. Read more |
Desktop performance needs improvement (61/100)
Warning
Medium Score is below 90. Tackle the highest-impact audits to push into the green. Read more |
Slow Speed Index (4.5 s)
Warning
Medium The page takes too long to visually complete. Optimize critical rendering path, reduce render-blocking resources, and serve visible content first. Read more |
Mobile performance needs improvement (54/100)
Warning
Medium Score is below 90. Tackle the highest-impact audits to push into the green. Read more |

Audit Details
| Audit | Insight | Impact |
|---|---|---|
| Minimize main-thread work | Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to minimize main-thread work | 3.7 s |
| 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.
| 2.1 s |
| 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 |
| Largest Contentful Paint | Largest Contentful Paint marks the time at which the largest text or image is painted. Learn more about the Largest Contentful Paint metric | 18.4 s |
| Use efficient cache lifetimes | A long cache lifetime can speed up repeat visits to your page. Learn more about caching.
| Est savings of 2,751 KiB |
| Legacy JavaScript | Polyfills and transforms enable older browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support older browsers. Learn why most sites can deploy ES6+ code without transpiling
| Est savings of 34 KiB |
| Render blocking requests | Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.
| Est savings of 770 ms |
| 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 |
| Improve image delivery | Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
| Est savings of 2,494 KiB |
| Reduce unused JavaScript | Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
| Est savings of 562 KiB |
| LCP request discovery | Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading | Open |
| Reduce unused CSS | Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity. Learn how to reduce unused CSS.
| Est savings of 73 KiB |
| Time to Interactive | Time to Interactive is the amount of time it takes for the page to become fully interactive. Learn more about the Time to Interactive metric. | 23.9 s |
| Speed Index | Speed Index shows how quickly the contents of a page are visibly populated. Learn more about the Speed Index metric. | 10.3 s |
| First Contentful Paint | First Contentful Paint marks the time at which the first text or image is painted. Learn more about the First Contentful Paint metric. | 3.1 s |

| Total size was 5,893 KiB |
| Max Potential First Input Delay | The maximum potential First Input Delay that your users could experience is the duration of the longest task. Learn more about the Maximum Potential First Input Delay metric. | 180 ms |
