zl1addons.com website review

14 images could be 467 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.9 s faster on a phone.

The page has 3,568 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google Tag Manager, rebuyengine.com and Klaviyo and others), adding 1.9 MB and 868 ms of main-thread time.

About 565 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.

Your mobile performance score is 57. Pages that score under 90 lose visitors before the first paint.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

9 files are served with short cache lifetimes, so returning visitors download them again (141 KiB).

A phone's processor spends 3.7 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

7 long tasks block the main thread while loading, the longest for 306 ms. During a long task the page ignores taps.

Google Tag Manager costs a phone 259 ms of main-thread work and 162 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.

rebuyengine.com costs a phone 190 ms of main-thread work and 706 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.

Klaviyo costs a phone 146 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.

Shopify costs a phone 86 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.

Polyfills for old browsers add 61 KiB JavaScript that modern phones do not need.

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

About 41 KiB of CSS is downloaded but never applied on this page.

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 8.6 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 23.4 s. Good is under 3.8 s.

Visually, the page fills in at 8.1 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 391 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 92 ms to 104 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 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.6 MB in 278 requests on a phone: scripts 1.6 MB (89), images 1.5 MB (35) and other files 943 KiB (128). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.29 g of CO₂e: 155.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA input fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

ARIA toggle fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

Headings skip levels (h1 → h5 and h2 → h4), which makes the page harder to scan with a screen reader.

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

Your meta description is 219 characters; Google truncates after about 160, so the end of your pitch is cut.

Your <h1> is empty.

The homepage links to 107 pages on zl1addons.com and 4 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.

https://zl1addons.com/collections/jackpads-magpads has no meta description, so Google writes the search snippet from whatever text it finds.

https://zl1addons.com/collections has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 55 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=17262717&Ver=2&mid=f27c260c-3db6-4d34-b211-85e90582bbe1&bo=1&sid=e96cc380ddd011f1ba799f96d83f2b9a&vid=e96d0680ddd011f1b95cbf7a461b46d0&vids=1&msclkid=N&pi=918639831&lg.

3 errors were logged to the browser console while the page loaded, for example “Shopify's Google Analytics stub called with: [array Array] See https://help.shopify.com/manual/promoting-marketing/pixe…”.

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.

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 438 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 20 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 33 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
