jumpflex.ca website review

5 images could be 229 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.2 s faster on a phone.

Your mobile performance score is 83. Pages that score under 90 lose visitors before the first paint.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 850 ms.

1 third-party service load with your homepage (Shopify), adding 1.0 MB and 11 ms of main-thread time.

Shopify costs a phone 11 ms of main-thread work and 1.0 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.

About 13 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

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.

Your largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Image of FLEX Trampolines”. Most of its time is element render delay (1.8 s).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.3 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 4.1 s. Good is under 3.8 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 94 ms to 98 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 22.7 MB in 30 requests on a phone: media 21.6 MB (4), images 959 KiB (22) and fonts 79 KiB (2). Under 2 MB keeps phones on slow connections fast.

e4d3308e3a394d748b2ec8b714153cae.thumbnail.0000000000.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image (41 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.

2 images further down the page (53 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 6.42 g of CO₂e: 770.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

7 visible links have no text or label, so screen readers cannot say where they go.

Alternative text of images should not be repeated as text: 3 elements on the page fail this check, rated minor by axe-core.

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

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 65 pages on jumpflex.ca and 14 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot), Claude search (Claude-SearchBot) and Perplexity (PerplexityBot) read the homepage but closes other sections to them, so answers about those pages can't cite you.

We fetched 15 pages linked from your homepage (of 32 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=343054612&tm=gtm002&Ver=2&mid=1bb27063-0037-4f90-b23b-6c65d601ba65&bo=3&sid=61a0aeb0dbd811f1a810f7f4895f28c5&vid=61a0d980dbd811f1a702edb82bdb9501&vids=0&msclkid=N&pi=9.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

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

5 links go through two or more redirects, for example https://yotpo.com/go/stwsJUL6.

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.

jumpflex.ca'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.

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.

The homepage carries about 842 words of visible text.

DMARC is set to p=none, so mail pretending to be jumpflex.ca 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, 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 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
