jackbox.tv website review

26 files are served with short cache lifetimes, so returning visitors download them again (1.6 MB).

About 368 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.0 s faster on a phone.

20 images could be 966 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

Your mobile performance score is 75 (desktop: 44). Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (Google Tag Manager, cdn-cookieyes.com and Sentry and others), adding 1.6 MB and 141 ms of main-thread time.

Google Tag Manager costs a phone 133 ms of main-thread work and 318 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.

jackboxgames.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.

About 16 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.

3 long tasks block the main thread while loading, the longest for 103 ms. During a long task the page ignores taps.

Polyfills for old browsers add 9 KiB JavaScript that modern phones do not need.

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

Your largest element takes 7.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Advert”.

The page becomes fully interactive after 9.7 s. Good is under 3.8 s.

21 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' tap response (inp) went from 106 ms to 112 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.0 MB in 43 requests on a phone: images 1.3 MB (23), scripts 710 KiB (6) and other files 33 KiB (10). Under 2 MB keeps phones on slow connections fast.

15 images (1.1 MB) 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.

1 image is downloaded at several times the size a phone draws it, for example pp11.png at 1,066 px wide, shown at 248 px. Resized copies would save about 88 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.57 g of CO₂e: 68.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

1 link inside paragraphs relies on colour alone to stand out.

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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

Your title is only 10 characters: “Jackbox.TV”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://jackbox.tv/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at jackbox.tv/robots.txt, the first file search crawlers ask for.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://jackbox.tv/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.

Large scripts ship without source maps.

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

The homepage has only about 108 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 3 cookies (measured from a US location before any click).

Loading the homepage contacts 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
