jitterbit.com website review

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

9 images could be 765 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 third-party services load with your homepage (Google Tag Manager, Google CDN and Optanon and others), adding 1.2 MB and 615 ms of main-thread time.

About 627 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 20 ms faster on a phone.

26 files are served with short cache lifetimes, so returning visitors download them again (313 KiB).

Google Tag Manager costs a phone 430 ms of main-thread work and 765 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 142 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 320 ms faster on a phone.

The page has 1,663 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

5 long tasks block the main thread while loading, the longest for 132 ms. During a long task the page ignores taps.

Polyfills for old browsers add 25 KiB JavaScript that modern phones do not need.

6 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.

5 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 11.9 s. Good is under 3.8 s.

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

Visually, the page fills in at 4.1 s (Speed Index). Good is under 3.4 s.

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

Your homepage downloads 3.1 MB in 157 requests on a phone: images 1.4 MB (86), scripts 1.3 MB (20) and stylesheets 145 KiB (7). Under 2 MB keeps phones on slow connections fast.

10 images (1.1 MB) are 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.

10 images further down the page (1.1 MB) 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 0.88 g of CO₂e: 105.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

9 buttons have no accessible name, so screen readers announce just “button”.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

Certain ARIA roles must be contained by particular parents: 1 element on the page fails this check, rated critical by axe-core.

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

8 tap targets are too small or too close together to hit reliably with a finger.

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

Banner landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Contentinfo landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one main landmark: 1 element on the page fails this check, rated moderate 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.

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

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

Alternative text of images should not be repeated as text: 5 elements on the page fail this check, rated minor by axe-core.

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

Structured data found (BreadcrumbList, Organization, WebPage and WebSite) but with 1 problem, for example “Organization: logo is not an absolute URL ("/wp-content/uploads/jitterbit-logo-h-1.svg")”.

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

5 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 328 pages on jitterbit.com and 21 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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.

/product/mcp and /ai have no meta description, so Google writes the search snippet from whatever text it finds.

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

/product/marketplace, /product/cloud-datastore, /product/message-queue and /ai took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 129 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://www.jitterbit.com/.

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

1 link to other sites is dead, for example https://docs.jitterbit.com/getting-started/jitterbit-support/ (404).

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

1 link go through two or more redirects, for example https://community.jitterbit.com/.

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.

jitterbit.com is registered until Dec 2026. Make sure auto-renew is on and the card on file is current.

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 452 words of visible text.

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 and Google Tag Manager (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Loading the homepage contacts 11 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
