underdogfantasy.com website review

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

12 images could be 630 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 800 ms faster on a phone.

Your mobile performance score is 65. Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (Google Tag Manager, website-files.com and datagrail.io and others), adding 2.1 MB and 268 ms of main-thread time.

About 64 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

About 60 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

website-files.com costs a phone 99 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.

1 file is served with short cache lifetimes, so returning visitors download them again (42 KiB).

2 long tasks block the main thread while loading, the longest for 60 ms. During a long task the page ignores taps.

12 KiB could be saved by minifying CSS.

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

The page becomes fully interactive after 10.1 s. Good is under 3.8 s.

The layout shifts by 0.173 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Visually, the page fills in at 4.1 s (Speed Index). Good is under 3.4 s.

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

Your homepage downloads 2.1 MB in 50 requests on a phone: fonts 970 KiB (17), images 825 KiB (21) and scripts 279 KiB (7). Under 2 MB keeps phones on slow connections fast.

6a8f2175221aa13873df43a3_1909b0ebce4c0b88a05c62a5ae4bac81_Un 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).

6 images (293 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 0.60 g of CO₂e: 71.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 visible links have no text or label, so screen readers cannot say where they go.

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Your title is 81 characters, so Google will cut it off around 60: “Underdog Sports: Predictions, Pick'em and Season-long Fantasy for NFL, NBA & more”.

There are 2 <h1> headlines (“DOGS COAST TO COAST” and “Make sports more fun on Underdog. Pick players, t…”). One clear main headline is easier for people and search engines.

Open Graph is missing og:title and og:description, so shared links fall back to guesses.

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

The homepage links to 14 pages on underdogfantasy.com and 18 external pages.

There is no https://www.underdogsports.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.

Your homepage links to https://www.underdogsports.com/promo-code, which answers with an error. Visitors hit a dead end and search engines drop it.

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

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

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://fonts.googleapis.com/css2?family=Kanit:ital,wght@0,100;00,700;0,800;0,900;1,100;1,…”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

1 image is served at too low a resolution for sharp phone screens.

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 323 words of visible text.

Before a visitor clicks anything, the page loads 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 3 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
