sling.com website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

A phone's processor spends 5.3 s on main-thread work while loading, 2.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

114 files are served with short cache lifetimes, so returning visitors download them again (3.6 MB).

About 1.7 MB of JavaScript is downloaded but never used on this page.

Your mobile performance score is 70 (desktop: 60). Pages that score under 90 lose visitors before the first paint.

About 565 KiB of CSS is downloaded but never applied on this page.

20 long tasks block the main thread while loading, the longest for 273 ms. During a long task the page ignores taps.

8 third-party services load with your homepage (The Trade Desk, Simplicity Marketing and Twitter Online Conversion Tracking and others), adding 30 KiB and 13 ms of main-thread time.

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

Polyfills for old browsers add 5 KiB JavaScript that modern phones do not need.

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.

The page becomes fully interactive after 16.1 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.1 s in total while the page loads. Good is under 200 ms.

For real visitors the layout shifts by 0.17 (75th percentile). Good is under 0.1.

Your largest element takes 3.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “SLING-Desktop-Marquee-DEMN-About?$transparent-png-desktop$”.

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

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

Your homepage downloads 4.4 MB in 185 requests on a phone: scripts 2.8 MB (57), stylesheets 862 KiB (44) and images 449 KiB (44). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.24 g of CO₂e: 148.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 11 elements on the page fail this check, rated moderate by axe-core.

Contentinfo landmark should not be contained in another landmark: 3 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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.

Elements marked as presentational should be consistently ignored: 1 element on the page fails this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (3 elements).

Your title is only 4 characters: “Home”. 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 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://www.sling.com/sitemap.xml, so Google discovers your pages only by following links.

3 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

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

The homepage links to 134 pages on sling.com and 12 external pages.

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 /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.

/service/add-ons, /features, /freestream, /whatson, /service and /service/compare-plans and 3 others have no <h1> headline, so visitors and search engines get no clear main topic.

/freestream, /service/sling-essentials, /service/sling-select, /service/sling-essentials-and-select, /service/sling-orange and /service/sling-blue and 1 other 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 15 pages linked from your homepage (of 62 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Mixed Content: The page at 'https://www.sling.com/' was loaded over HTTPS, but requested an insecure script 'http://www…”.

Large scripts ship without source maps.

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.

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 927 words of visible text.

Before a visitor clicks anything, the page loads Amazon Ads, Google Tag Manager, Microsoft Ads, Reddit Pixel and The Trade Desk and 2 mores (measured from a US location before any click). A consent tool (Ketch) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 29 cookies (measured from a US location before any click).

Loading the homepage contacts 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
