prisync.com website review

51 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.0 s.

About 463 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.7 s faster on a phone.

Your mobile performance score is 47 (desktop: 69). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Mixpanel and others), adding 915 KiB and 970 ms of main-thread time.

121 files are served with short cache lifetimes, so returning visitors download them again (312 KiB).

Google Tag Manager costs a phone 686 ms of main-thread work and 510 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.

About 75 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 310 ms faster on a phone.

12 long tasks block the main thread while loading, the longest for 366 ms. During a long task the page ignores taps.

A phone's processor spends 2.9 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Polyfills for old browsers add 32 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 100 ms faster on a phone.

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

3 KiB could be saved by minifying JavaScript.

1 image could be 17 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

7 KiB could be saved by minifying CSS.

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.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Real visitors see the first content after 3.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 2.3 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 11.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Competitor Price Tracking & Monitoring Software”.

The page becomes fully interactive after 13.4 s. Good is under 3.8 s.

Visually, the page fills in at 9.2 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.5 s on a phone. Good is under 1.8 s.

Real visitors wait 3.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 203 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Scripts block taps and scrolling for 522 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 125 ms to 141 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.4 s to 3.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

1 image (71 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 0.51 g of CO₂e: 61.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 4 elements on the page fail this check, rated critical by axe-core.

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

All page content should be contained by landmarks: 48 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

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

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

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

4 links have no real href, so search engines can't follow them.

The homepage links to 66 pages on prisync.com and 21 external pages.

We fetched 15 pages linked from your homepage (of 33 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=56012727&tm=gtm002&Ver=2&mid=2d6a4a95-8ffd-4722-b402-8ac07e9593ee&bo=1&sid=b2b344a0cca811f1ac98859153a7be18&vid=b2b386f0cca811f1b32383e5d6390fd3&vids=1&msclkid=N&pi=91.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

4 links go through two or more redirects, for example https://app.prisync.com/register?package=1.

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.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

prisync.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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage carries about 666 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

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 Microsoft Ads 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 9 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 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
