Observer's Performance Suggestions
Priority actions Observer identified from this test to improve speed, reliability, and user experience.
Poor desktop performance score (33/100)
Error
High Lighthouse rates this page as poor. Address render-blocking, image, and JavaScript audits below. Read more |
Poor mobile performance score (42/100)
Error
High Lighthouse rates this page as poor. Address render-blocking, image, and JavaScript audits below. Read more |
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 |
High Total Blocking Time (9541 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 |
Slow Speed Index (14.3 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 |
Slow Speed Index (12.4 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 |
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=U5VsmTDhJM1iOJUyw4DEUTYv&size=invisible&anchor-ms=20000&execute-ms=30000&cb=dqfos8vovn70 at 2163 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 |

Audit Details
| Audit | Insight | Impact |
|---|---|---|
| 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 1,420 ms |
| 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 |
| 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 |
| 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 | 5.4 s |
| 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 672 KiB |
| 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 | 21.0 s |
| LCP breakdown | Each subpart has specific improvement strategies. Ideally, most of the LCP time should be spent on loading the resources, not within delays. | Open |
| LCP request discovery | Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading | Open |
| 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 560 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 |

| Avoid enormous network payloads | Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
| Total size was 5,950 KiB |
| Total Blocking Time | Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds. Learn more about the Total Blocking Time metric. | 560 ms |
