blocout.com website review

The page has 3,060 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 68. Pages that score under 90 lose visitors before the first paint.

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

About 197 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

8 third-party services load with your homepage (heatmap.com, Klaviyo and Clarity and others), adding 838 KiB and 529 ms of main-thread time.

A phone's processor spends 3.7 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Klaviyo costs a phone 98 ms of main-thread work and 321 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 long tasks block the main thread while loading, the longest for 132 ms. During a long task the page ignores taps.

19 files are served with short cache lifetimes, so returning visitors download them again (78 KiB).

Polyfills for old browsers add 40 KiB JavaScript that modern phones do not need.

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.

1 image could be 4 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Your largest element takes 14.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “By clicking “Accept all”, you agree that our website can st…”.

The page becomes fully interactive after 16.9 s. Good is under 3.8 s.

Visually, the page fills in at 5.3 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 135 ms to 146 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 1.6 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.8 MB in 389 requests on a phone: images 2.8 MB (132), scripts 1,013 KiB (97) and other files 845 KiB (106). Under 2 MB keeps phones on slow connections fast.

39 images (1.5 MB) 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.

Samples.png 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).

3 images are downloaded at several times the size a phone draws them, for example touch_1_DIGIBB-DSG-BO.webp at 600 px wide, shown at 105 px. Resized copies would save about 141 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.64 g of CO₂e: 196.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

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

1 visible link has no text or label, so screen readers cannot say where it goes.

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Table header text should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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

Your title is 70 characters, so Google will cut it off around 60: “BlocOut Blinds – Premium Blackout Solutions for Better Sleep – blocout”.

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.

Your <h1> is empty.

The homepage links to 157 pages on blocout.com and 14 external pages.

https://blocout.com/pages/builder has no meta description, so Google writes the search snippet from whatever text it finds.

https://blocout.com/collections/accessories, https://blocout.com/pages/builder, https://blocout.com/collections/bedroom-blackout-blinds, https://blocout.com/collections/nursery-blackout-blinds, https://blocout.com/collections/media-room-blackout-blinds and https://blocout.com/collections/white-natural-fabrics and 6 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 40 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=343181366&Ver=2&mid=e28e5e04-b0e7-4bfe-9e6a-28af7344e8df&bo=1&sid=292c01d0dd3811f1b3606d2eebe9d742&vid=292c6170dd3811f18a6f1f8fb65e5d40&vids=1&msclkid=N&pi=918639831&l.

6 of 23 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 “KlaviyoSubscribe is not defined”.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage shows no opening hours. If customers visit or call, show when.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 645 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 3 mores (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 28 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 49 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
