adp.com website review

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

Google Tag Manager costs a phone 1.1 s of main-thread work and 1.2 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Your mobile performance score is 41 (desktop: 60). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 8.6 s on main-thread work while loading, 5.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Evergage and site.com and others), adding 3.5 MB and 3.1 s of main-thread time.

About 1.5 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

75 files are served with short cache lifetimes, so returning visitors download them again (825 KiB).

Evergage costs a phone 963 ms of main-thread work and 70 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.

site.com costs a phone 392 ms of main-thread work and 1.5 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 174 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 340 ms faster on a phone.

20 long tasks block the main thread while loading, the longest for 337 ms. During a long task the page ignores taps.

The page has 2,305 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Optanon costs a phone 90 ms of main-thread work and 299 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.

1 image could be 17 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

Polyfills for old browsers add 46 KiB JavaScript that modern phones do not need.

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 page becomes fully interactive after 33.6 s. Good is under 3.8 s.

Scripts block taps and scrolling for 2.4 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 11.0 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 329 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

For real visitors the layout shifts by 0.15 (75th percentile). Good is under 0.1.

Real visitors wait 970 ms for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 3.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Experience better HR and payroll”. Most of its time is element render delay (1.9 s).

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

The layout shifts by 0.151 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 225 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 2026-10-03, real Chrome visitors' largest content (lcp) went from 2.5 s to 2.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.7 MB in 209 requests on a phone: scripts 3.6 MB (69), images 556 KiB (60) and stylesheets 178 KiB (6). Under 2 MB keeps phones on slow connections fast.

navpromo_runproductscreen.png 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 (94 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 1.32 g of CO₂e: 158.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 button has no accessible name, so screen readers announce just “button”.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 9 elements on the page fail 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.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

Elements marked as presentational should be consistently ignored: 1 element on the page fails this check, rated minor by axe-core.

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

Elements with visible text labels do not have matching accessible names. (2 elements).

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

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 258 pages on adp.com and 24 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.

/terms/3-month-offer-terms.aspx is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/terms/3-month-offer-terms.aspx has no meta description, so Google writes the search snippet from whatever text it finds.

/terms/3-month-offer-terms.aspx has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 114 found) and read each the way a search engine does.

10 images failed to load on a phone, for example https://www.adp.com/-/media/adp2025/ui/logo-adp.svg?rev=2ffd0a893eca4842b0f071c1e9c186b8&hash=85D6D9870432E605FE0FD7F830F16744.

90 of 102 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

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 403 ()”.

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

1 link to other sites is dead, for example https://info.adp.com/insights-in-action-2026-registration?partnerref=com (404).

HSTS is set, but max-age is 182 days; one year is the recommended minimum.

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

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.

adp.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.

adp.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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Your longest form asks for 9 fields (0 required). Every extra field lowers completion.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 2,516 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, Google Tag Manager, LinkedIn Insight and Meta Pixel and 4 mores (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.

Opening the homepage sets 30 cookies, 4 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 58 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
