posterjack.com website review

About 207 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.3 s faster on a phone.

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

14 images could be 343 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 550 ms faster on a phone.

8 third-party services load with your homepage (pxlecdn.com, Pixlee and OptiMonk and others), adding 1.6 MB and 713 ms of main-thread time.

Polyfills for old browsers add 69 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 550 ms faster on a phone.

About 69 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 490 ms faster on a phone.

pxlecdn.com costs a phone 342 ms of main-thread work and 1.1 MB 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.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

A phone's processor spends 2.4 s on main-thread work while loading, 974 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

11 files are served with short cache lifetimes, so returning visitors download them again (37 KiB).

2 long tasks block the main thread while loading, the longest for 156 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 15.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The first text or image appears after 6.8 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 16.1 s. Good is under 3.8 s.

Visually, the page fills in at 8.0 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 104 ms to 94 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 280 requests on a phone: images 1.1 MB (35), scripts 1.1 MB (112) and other files 799 KiB (108). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.97 g of CO₂e: 116.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

9 elements hidden from screen readers can still receive keyboard focus.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Your meta description is 201 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 134 pages on posterjack.com and 15 external pages.

/collections/all has no meta description, so Google writes the search snippet from whatever text it finds.

/collections/all has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 39 found) and read each the way a search engine does.

36 of 48 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_CONNECTION_RESET”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

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.

posterjack.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.

posterjack.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.

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 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.

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 554 words of visible text.

DMARC is set to p=none, so mail pretending to be posterjack.com is still delivered. Reports are on, so moving to quarantine is the next step.

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 and Klaviyo (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, 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 39 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
