stickermule.com website review

Your mobile performance score is 74. Pages that score under 90 lose visitors before the first paint.

About 281 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 750 ms.

20 files are served with short cache lifetimes, so returning visitors download them again (255 KiB).

Wistia costs a phone 260 ms of main-thread work and 336 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.

9 images could be 243 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

2 third-party services load with your homepage (Wistia and Adobe TypeKit), adding 370 KiB and 260 ms of main-thread time.

Polyfills for old browsers add 15 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

6 long tasks block the main thread while loading, the longest for 139 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (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 5.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Custom printing that kicks ass Free worldwide shipping. Fas…”.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 115 ms to 138 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The page becomes fully interactive after 7.0 s. Good is under 3.8 s.

Scripts block taps and scrolling for 256 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.

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

1 image (80 KiB) is 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 0.35 g of CO₂e: 41.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

The homepage links to 83 pages on stickermule.com and 4 external pages.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /support, whose canonical is /support/chat. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/support has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 38 found) and read each the way a search engine does.

41 of 56 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Loading the script 'https://browser.sentry-cdn.com/9.6.1/bundle.min.js' violates the following Content Security Policy …”.

10 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

Large scripts ship without source maps.

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.

stickermule.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.

stickermule.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 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.

The homepage has only about 197 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

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, LinkedIn Insight and Meta Pixel and 4 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 7 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 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
