undersummers.com website review

About 389 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, iovation and Accessibe Accessibility Overlay and others), adding 948 KiB and 1.2 s of main-thread time.

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

Google Tag Manager costs a phone 388 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.

A phone's processor spends 3.3 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

5 long tasks block the main thread while loading, the longest for 265 ms. During a long task the page ignores taps.

About 45 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.

10 files are served with short cache lifetimes, so returning visitors download them again (33 KiB).

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

2 images could be 87 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 50 ms.

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 9.1 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 11.6 s. Good is under 3.8 s.

Scripts block taps and scrolling for 702 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.5 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 158 ms to 188 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.5 MB in 198 requests on a phone: scripts 1.0 MB (52), other files 853 KiB (124) and images 331 KiB (9). Under 2 MB keeps phones on slow connections fast.

Black_and_White_Bold_Minimalist_Carousel_Instagram_Post_1.pn 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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.70 g of CO₂e: 83.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

6 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: 7 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

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

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

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

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

Your meta description is 287 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 40 pages on undersummers.com and 0 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.

Your homepage links to https://undersummers.com/products/fusion-moisture-wicking-anti-chafing-shortlette-slipshort-9-ecru-cream and https://undersummers.com/products/womens-boxer-brief-with-1-waist-pocket-5-plus-size-3, which answer with an error. Visitors hit a dead end and search engines drop them.

Your homepage links to 3 pages by a URL that isn't their canonical one, for example https://undersummers.com/collections/all-products/products/neutral-color-slip-short-1, whose canonical is https://undersummers.com/products/neutral-color-slip-short-1. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://undersummers.com/collections/last-chance-almost-gone-undersummers-sale-items and https://undersummers.com/collections/seasonal-sale have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 27 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=187104054&tm=gtm002&Ver=2&mid=c079226d-d2b4-4ef7-b1c6-9511aa496f9a&bo=1&sid=b8566170dcc011f18c83235ba2a1612a&vid=b8568480dcc011f1b7ab27a92b048829&vids=1&msclkid=N&gtm_.

4 of 16 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

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 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 357 words of visible text.

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

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Microsoft Ads 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 12 cookies, 2 of them by other companies (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 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
