boostmobile.com website review

57 files are served with short cache lifetimes, so returning visitors download them again (398 KiB).

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

The page has 3,450 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 59 (desktop: 86). Pages that score under 90 lose visitors before the first paint.

6 images could be 110 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 350 ms faster on a phone.

About 32 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 32 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.

A phone's processor spends 2.2 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

9 long tasks block the main thread while loading, the longest for 185 ms. During a long task the page ignores taps.

4 third-party services load with your homepage (Adobe Tag Manager, f5apis.com and Adobe Scene7 and others), adding 357 KiB and 138 ms of main-thread time.

Desktop scores 86 but mobile only 59. A gap that wide usually means heavy scripts and images that hit phones hardest.

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 JavaScript.

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

The first text or image appears after 3.6 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 8.3 s. Good is under 3.8 s.

Visually, the page fills in at 6.0 s (Speed Index). Good is under 3.4 s.

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 232 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.5 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 229 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 3.4 s to 3.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

1 image (78 KiB) is 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 further down the page (25 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.30 g of CO₂e: 35.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

7 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 86 elements on the page fail this check, rated moderate by axe-core.

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

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

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

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

There are 2 <h1> headlines (“UNLIMITED WIRELESS” and “$10/MO”). One clear main headline is easier for people and search engines.

Your meta description is 161 characters; Google truncates after about 160, so the end of your pitch is cut.

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

The homepage links to 203 pages on boostmobile.com and 29 external pages.

Your Organization JSON-LD is missing logo, sameAs (social profiles) and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

/shop/activation_v2/start has no meta description, so Google writes the search snippet from whatever text it finds.

/locations/locator has no <h1> headline, so visitors and search engines get no clear main topic.

/shop/activation_v2/start has 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 63 found) and read each the way a search engine does.

18 of 43 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 (“Synchronous `XMLHttpRequest` on the main thread is deprecated because of its detrimental effects to…”).

2 errors were logged to the browser console while the page loaded, for example “Cannot read properties of undefined (reading 'catch')”.

4 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

6 links go through two or more redirects, for example https://www.boostmobile.com/shop/customer/account/index.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

boostmobile.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

boostmobile.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage carries about 861 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

DMARC is set to p=none, so mail pretending to be boostmobile.com is still delivered. Reports are on, so moving to quarantine is the next step.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Reddit Pixel 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 32 cookies (measured from a US location before any click).

Loading the homepage contacts 42 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
