Otoritas halaman menggunakan skala logaritmik 0 hingga 100. Skor otoritas Halaman yang tinggi berarti halaman Anda memiliki potensi untuk mendapatkan peringkat yang baik di hasil mesin pencari.

    Apa itu Peringkat Moz? Moz Rank adalah salah satu metrik paling populer dan handal jika Anda ingin mengukur otoritas domain atau halaman web. Moz membuat metrik Mozrank untuk menghitung peringkat pengoptimalan mesin pencari dari halaman web atau situs web tertentu.

    Apa itu Bounce Rate? Tingkat pentalan atau bounce rate adalah sesi satu halaman dibagi dengan semua sesi, atau persentase dari semua sesi di situs Anda dimana pengguna hanya melihat satu halaman dan hanya memicu satu permintaan ke server Analytics. Rasio pentalan dapat digunakan untuk membantu menentukan keefektifan atau kinerja halaman dalam membangkitkan minat pengunjung. Halaman dengan rasio pentalan rendah berarti halaman tersebut secara efektif menyebabkan pengunjung melihat lebih banyak halaman dan melanjutkan eksplorasi di web Anda.

    sigra369bm.shop Desktop: Kiat Kecepatan dan Pengoptimalan

    Tangkapan Layar Desktop
    Elemen Cat Konten Terbesar 1,620 ms
    This is the largest contentful element painted within the viewport
    Tunda gambar di luar layar Potential savings of 7 KiB
    Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
    Sajikan aset statis dengan kebijakan cache yang efisien 4 resources found
    A long cache lifetime can speed up repeat visits to your page
    Hindari merantai permintaan kritis 13 chains found
    The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load
    Hindari animasi yang tidak dikomposisikan 1 animated element found
    Animations which are not composited can be janky and increase CLS
    Ukuran gambar yang benar Potential savings of 1,176 KiB
    Serve images that are appropriately-sized to save cellular data and improve load time
    Hindari muatan jaringan yang sangat besar Total size was 6,007 KiB
    Large network payloads cost users real money and are highly correlated with long load times
    Max Potensi Penundaan Input Pertama 110 ms
    The maximum potential First Input Delay that your users could experience is the duration of the longest task
    Hindari tugas main-thread yang panjang 3 long tasks found
    Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
    Waktu eksekusi JavaScript 0.4 s
    Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
    Kurangi CSS yang tidak digunakan Potential savings of 44 KiB
    Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity
    Cat Bermakna Pertama 0.8 s
    First Meaningful Paint measures when the primary content of a page is visible
    Kecepatan Indeks 1.6 s
    Speed Index shows how quickly the contents of a page are visibly populated
    Hindari ukuran DOM yang berlebihan 2,158 elements
    A large DOM will increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow)
    Waktu Perjalanan Jaringan 60 ms
    Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance
    Kurangi JavaScript yang tidak digunakan Potential savings of 226 KiB
    Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity
    Sajikan gambar dalam format generasi berikutnya Potential savings of 151 KiB
    Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption

    Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences
    Hindari menyajikan JavaScript lama ke browser modern Potential savings of 11 KiB
    Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers
    Cat Konten Terbesar 1.6 s
    Largest Contentful Paint marks the time at which the largest text or image is painted
    Total Waktu Pemblokiran 70 ms

    Kurangi waktu respons server awal Root document took 840 ms
    Keep the server response time for the main document short because all other requests depend on it
    Minimalkan penggunaan pihak ketiga Third-party code blocked the main thread for 100 ms
    Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading
    Meminimalkan pekerjaan utas utama 1.5 s
    Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this

    Pergeseran Tata Letak Kumulatif 0.063
    Cumulative Layout Shift measures the movement of visible elements within the viewport
    Gunakan format video untuk konten animasi Potential savings of 2,086 KiB
    Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes
    Latensi Backend Server 930 ms
    Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance
    Hindari pergeseran tata letak yang besar 15 layout shifts found
    These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most.

    The maximum potential First Input Delay that your users could experience is the duration of the longest task
    Dokumen menggunakan ukuran font yang dapat dibaca 93.92% legible text
    Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px
