sealitgreen.com website review

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 8.2 s.

About 718 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Shopify, Clarity and vitals.app and others), adding 1.8 MB and 443 ms of main-thread time.

About 82 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.

A phone's processor spends 3.4 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

4 long tasks block the main thread while loading, the longest for 252 ms. During a long task the page ignores taps.

Shopify costs a phone 145 ms of main-thread work and 937 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 2,183 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

azurefd.net costs a phone 51 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.

7 images could be 65 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 43 KiB JavaScript that modern phones do not need.

9 files are served with short cache lifetimes, so returning visitors download them again (31 KiB).

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.

Visually, the page fills in at 16.2 s (Speed Index). Good is under 3.4 s.

Your largest element takes 9.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is resource load delay (5.7 s).

The page becomes fully interactive after 16.6 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 104 ms to 162 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 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.4 MB in 290 requests on a phone: scripts 1.7 MB (160), images 1.6 MB (36) and other files 559 KiB (55). Under 2 MB keeps phones on slow connections fast.

17 images (782 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.25 g of CO₂e: 150.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

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

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.

Elements with visible text labels do not have matching accessible names. (1 element).

The homepage links to 89 pages on sealitgreen.com and 13 external pages.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.sealitgreen.com/products/marine-plant-based-sealer, whose canonical is https://www.sealitgreen.com/products/marine-armor. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.sealitgreen.com/pages/vinyl-renu has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 32 found) and read each the way a search engine does.

5 errors were logged to the browser console while the page loaded, for example “$ is not defined”.

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.

Social proof on the homepage: 174 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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

The homepage carries about 628 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 1 more (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 32 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
