nbcsports.com website review

45 files are served with short cache lifetimes, so returning visitors download them again (906 KiB).

About 1.5 MB 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.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 34. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 7,062 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 7.0 s on main-thread work while loading, 3.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Taboola, Facebook and Google Tag Manager and others), adding 3.3 MB and 2.0 s of main-thread time.

16 images could be 550 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.

Polyfills for old browsers add 79 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 750 ms faster on a phone.

Taboola costs a phone 533 ms of main-thread work and 1.6 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 143 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 400 ms faster on a phone.

34 KiB could be saved by minifying JavaScript.

Facebook costs a phone 325 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.

Google Tag Manager costs a phone 303 ms of main-thread work and 342 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/Doubleclick Ads costs a phone 236 ms of main-thread work and 426 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.

20 long tasks block the main thread while loading, the longest for 224 ms. During a long task the page ignores taps.

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.

2 KiB could be saved by minifying CSS.

Your largest element takes 22.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Tennessee Titans v Baltimore Ravens”.

The page becomes fully interactive after 41.3 s. Good is under 3.8 s.

Visually, the page fills in at 14.9 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 6.1 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 957 ms in total while the page loads. Good is under 200 ms.

1 image 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 146 ms to 153 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.9 MB in 480 requests on a phone: scripts 3.4 MB (77), images 1.7 MB (162) and other files 450 KiB (206). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.66 g of CO₂e: 199.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

25 elements hidden from screen readers can still receive keyboard focus.

Some lists contain elements other than list items, which screen readers announce wrongly.

Some list items are not inside a list.

All page content should be contained by landmarks: 7 elements on the page fail this check, rated moderate by axe-core.

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

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

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

Elements with visible text labels do not have matching accessible names. (23 elements).

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

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

10 links have no real href, so search engines can't follow them.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 591 pages on nbcsports.com and 103 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 https://www.nbcsports.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.

We fetched 15 pages linked from your homepage (of 198 found) and read each the way a search engine does.

26 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

18 of 60 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

4 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://widgets.media.sportradar.com/assets/css/chunk.2516.9ed5e022.css' from origin 'http…”.

Chrome logged issues while loading the page (“Mixed content”).

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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 carries about 2,871 words of visible text.

Before a visitor clicks anything, the page loads Amazon Ads, Comscore, Criteo, Google Ads and Google Analytics and 3 mores (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 27 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 41 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
