viki.com website review

15 images could be 1.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.7 s faster on a phone.

About 338 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

Your mobile performance score is 39 (desktop: 54). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 4,315 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 4.1 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (viki.io, Google Tag Manager and privacy-mgmt.com and others), adding 2.6 MB and 1.3 s of main-thread time.

viki.io costs a phone 648 ms of main-thread work and 630 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Google Tag Manager costs a phone 568 ms of main-thread work and 505 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

13 long tasks block the main thread while loading, the longest for 485 ms. During a long task the page ignores taps.

7 files are served with short cache lifetimes, so returning visitors download them again (75 KiB).

Polyfills for old browsers add 42 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

vikiplatform.com costs a phone 0 ms of main-thread work and 1.3 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

7 KiB could be saved by minifying JavaScript.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 13.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Dive into You”.

The page becomes fully interactive after 14.4 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.2 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.5 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 6.6 s (Speed Index). Good is under 3.4 s.

Real visitors wait 4.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 222 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

6 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 3.6 s to 3.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.6 MB in 148 requests on a phone: images 1.3 MB (21), scripts 1.2 MB (103) and HTML 57 KiB (1). Under 2 MB keeps phones on slow connections fast.

0772e6cf3d.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

7 images are downloaded at several times the size a phone draws them, for example d4c8c4e890.png at 2,601 px wide, shown at 351 px. Resized copies would save about 298 KiB.

6 images (437 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.75 g of CO₂e: 89.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

6 tap targets are too small or too close together to hit reliably with a finger.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

The page declares lang=“%lang%”, which is not a usable language code, so screen readers and translation tools guess.

There is no <h1>, so neither visitors nor Google get a clear main headline.

The homepage links to 16 pages on viki.com and 20 external pages.

A phone browser shows 1,129 words, but the HTML your server sends has only 64. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

There is no https://www.viki.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/, https://www.viki.com/categories, https://www.viki.com/apps, https://www.viki.com/partners, https://www.viki.com/advertise and https://www.viki.com/press and 4 others all use the title “Watch K-Dramas, Korean Shows & Chinese Dramas | Rakuten Viki”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.viki.com/categories, https://www.viki.com/apps, https://www.viki.com/partners, https://www.viki.com/advertise, https://www.viki.com/press and https://www.viki.com/legal/terms_of_use and 3 others use the same meta description. A description written for each page earns more clicks.

Your homepage links to 4 pages by a URL that isn't their canonical one, for example https://www.viki.com/movies, whose canonical is https://www.viki.com/movies?locale=en. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.viki.com/movies has no <h1> headline, so visitors and search engines get no clear main topic.

https://www.viki.com/categories, https://www.viki.com/movies, https://www.viki.com/apps and https://www.viki.com/advertise have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 11 pages linked from your homepage and read each the way a search engine does.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 1,129 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 10 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
