boostdrinks.com website review

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 1.5 s.

About 160 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

18 images could be 474 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 650 ms faster on a phone.

Your mobile performance score is 62 (desktop: 99). Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 187 ms of main-thread work and 310 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.

5 third-party services load with your homepage (Google Tag Manager, Clarity and Klaviyo and others), adding 624 KiB and 416 ms of main-thread time.

About 26 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.

3 long tasks block the main thread while loading, the longest for 127 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 18 KiB JavaScript that modern phones do not need.

3 files are served with short cache lifetimes, so returning visitors download them again (15 KiB).

Desktop scores 99 but mobile only 62. 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.

Your largest element takes 15.4 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 15.7 s. Good is under 3.8 s.

The first text or image appears after 5.0 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.0 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 104 ms to 111 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, 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 5.5 MB in 271 requests on a phone: media 1.7 MB (1), images 1.6 MB (30) and other files 1.0 MB (169). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (35 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 1.56 g of CO₂e: 187.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

2 images have no alt text, which hurts accessibility and image search.

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

There are 3 <h1> headlines (“Boost Drinks”, “HYDRATION & ENERGY THAT HITS DIFFERENT” and “Boost Drinks”). One clear main headline is easier for people and search engines.

The homepage links to 41 pages on boostdrinks.com and 9 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description 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.

/pages/contact, /policies/privacy-policy and /policies/terms-of-service have no meta description, so Google writes the search snippet from whatever text it finds.

/collections/boost-energy, /collections/boost-sport, /collections/boost-water, /collections/boost-coffee, /collections/boost-juicd and /collections/hydration-powders and 6 others have no <h1> headline, so visitors and search engines get no clear main topic.

/collections/boost-energy, /collections/boost-sport, /collections/boost-water, /collections/boost-coffee, /collections/boost-juicd and /collections/hydration-powders and 2 others 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 17 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

2 links go through two or more redirects, for example https://www.boostdrinks.com/customer_authentication/redirect?locale=en&region_country=GB.

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.

boostdrinks.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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 93 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 Tag Manager, Klaviyo, Meta Pixel and Microsoft Clarity (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 18 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 23 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
