jambu.com website review

About 840 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.7 s faster on a phone.

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

A phone's processor spends 5.7 s on main-thread work while loading, 2.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (iubenda, ContentSquare and Google Tag Manager and others), adding 1.4 MB and 1.3 s of main-thread time.

Your mobile performance score is 54. Pages that score under 90 lose visitors before the first paint.

22 images could be 507 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

27 files are served with short cache lifetimes, so returning visitors download them again (236 KiB).

iubenda costs a phone 417 ms of main-thread work and 122 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.

ContentSquare costs a phone 361 ms of main-thread work and 185 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.

The page has 1,754 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

LoyaltyLion costs a phone 51 ms of main-thread work and 364 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.

12 long tasks block the main thread while loading, the longest for 242 ms. During a long task the page ignores taps.

About 63 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.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

8 KiB could be saved by minifying JavaScript.

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.

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 17.1 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 21.4 s. Good is under 3.8 s.

Visually, the page fills in at 7.5 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.1 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.12 (75th percentile). Good is under 0.1.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 142 ms to 187 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.6 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 498 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Your homepage downloads 4.9 MB in 300 requests on a phone: scripts 2.1 MB (103), images 1.7 MB (43) and other files 717 KiB (131). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.38 g of CO₂e: 166.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Your title is only 11 characters: “Jambu & Co.”. Between 30 and 65 characters leaves room to say what you do and for whom.

There are 2 <h1> headlines (“Jambu” and “Jambu”). One clear main headline is easier for people and search engines.

Your meta description is 245 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 140 pages on jambu.com and 5 external pages.

/collections/select-styles-up-to-50-off, /collections/best-seller, /collections/all-boots, /collections/mary-janes, /collections/all-sandals-1 and /collections/all-sneakers-1 and 8 others have no meta description, so Google writes the search snippet from whatever text it finds.

/collections/select-styles-up-to-50-off, /collections/best-seller, /collections/all-boots, /collections/mary-janes, /collections/all-sandals-1 and /collections/all-sneakers-1 and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 63 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=52004610&Ver=2&mid=843c5270-2025-4d88-87fd-54bc659c8f73&bo=3&sid=4152e460d94b11f18b6d7307d66989b8&vid=41533210d94b11f1a259b5337e42ddd6&vids=0&msclkid=N&pi=918639831&lg.

33 of 50 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 errors were logged to the browser console while the page loaded, for example “Identifier 'nvdConsentConfig' has already been declared”.

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

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.

jambu.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.

jambu.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 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.

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 306 words of visible text.

DMARC is set to p=none, so mail pretending to be jambu.com is still delivered. Add a report address, check the reports, then move to quarantine.

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 Microsoft Ads and 2 mores (measured from a US location before any click). A consent tool (iubenda) 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 56 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
