authorize.net website review

About 1.2 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 10.3 s faster on a phone.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

7 third-party services load with your homepage (YouTube, Google Tag Manager and Optimizely and others), adding 2.4 MB and 1.1 s of main-thread time.

35 files are served with short cache lifetimes, so returning visitors download them again (264 KiB).

Your mobile performance score is 52. Pages that score under 90 lose visitors before the first paint.

YouTube costs a phone 750 ms of main-thread work and 2.0 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 141 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

A phone's processor spends 2.5 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,909 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

6 images could be 210 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.

18 KiB could be saved by minifying JavaScript.

12 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 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.

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.

The first text or image appears after 13.9 s on a phone. Good is under 1.8 s.

Your largest element takes 21.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 13.9 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 21.1 s. Good is under 3.8 s.

Real visitors wait 202 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.0 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Scripts block taps and scrolling for 209 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 194 ms to 225 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 3.3 s to 3.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 72 requests on a phone: scripts 2.2 MB (19), images 398 KiB (21) and fonts 381 KiB (6). Under 2 MB keeps phones on slow connections fast.

1623941357644.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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.95 g of CO₂e: 114.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

27 elements have a tabindex above 0, which scrambles the keyboard order.

Interactive controls must not be nested: 3 elements on the page fail this check, rated serious by axe-core.

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

Your title is 85 characters, so Google will cut it off around 60: “Credit card payment processor, online payments systems and processing | Authorize.net”.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

Your meta description is 244 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image (also missing: og:title, og:description), 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 59 pages on authorize.net and 12 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

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.

We fetched 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

26 of 42 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

1 image is served at too low a resolution for sharp phone screens.

Chrome logged issues while loading the page (“Cookie”).

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

1 link go through two or more redirects, for example https://www.visa.com/privacy.

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.

authorize.net 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.

authorize.net'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.

Social proof on the homepage: 1 customer or partner logo. Pairing it with named testimonials or customer logos makes it far more convincing.

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 865 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 and Google Tag Manager (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 5 cookies, 1 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 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
