drivingdynamics.com website review

4 images could be 789 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 4.0 s faster on a phone.

47 files are served with short cache lifetimes, so returning visitors download them again (473 KiB).

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

Google CDN costs a phone 1.3 s of main-thread work and 1.8 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 40 (desktop: 37). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.2 s on main-thread work while loading, 3.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Other Google APIs/SDKs and others), adding 2.5 MB and 1.9 s of main-thread time.

About 1.3 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

About 56 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.

Google Tag Manager costs a phone 323 ms of main-thread work and 326 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.

20 long tasks block the main thread while loading, the longest for 267 ms. During a long task the page ignores taps.

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.

Your largest element takes 13.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 24.3 s. Good is under 3.8 s.

Visually, the page fills in at 7.0 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 865 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

The layout shifts by 0.129 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.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 5.5 MB in 135 requests on a phone: scripts 2.4 MB (37), images 1.7 MB (36) and other files 816 KiB (31). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.57 g of CO₂e: 187.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

5 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: 11 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.

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

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

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.

The homepage links to 32 pages on drivingdynamics.com and 9 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.

Your homepage links to /driver-advantage-old, which answers with an error. Visitors hit a dead end and search engines drop it.

We fetched 15 pages linked from your homepage (of 18 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://use.fontawesome.com/releases/v5.8.1/css/all.css' from origin 'https://www.drivingd…”.

Large scripts ship without source maps.

1 link from your homepage to your own site is broken, for example https://www.drivingdynamics.com/driver-advantage-old (404).

http://drivingdynamics.com does not redirect to https, so some visitors land on the insecure version.

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

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.

drivingdynamics.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.

drivingdynamics.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.

Social proof on the homepage: 2 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 149 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

DMARC is set to p=none, so mail pretending to be drivingdynamics.com 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, HubSpot and LinkedIn Insight (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 15 cookies (measured from a US location before any click).

Loading the homepage contacts 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
