jderenzo.com website review

8 images could be 1.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

26 files are served with short cache lifetimes, so returning visitors download them again (937 KiB).

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 300 ms).

About 17 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 290 ms faster on a phone.

About 21 KiB of JavaScript is downloaded but never used on this page.

1 third-party service load with your homepage (Adobe TypeKit), adding 142 KiB and 4 ms of main-thread time.

Polyfills for old browsers add 7 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.

Visually, the page fills in at 4.5 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.141 while loading, so content jumps under the reader's thumb. Good is under 0.1.

12 images 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.

home_about.png weighs 1,003 KiB. On a phone connection a single image that size takes seconds.

Your homepage downloads 2.4 MB in 32 requests on a phone: images 2.2 MB (15), fonts 140 KiB (6) and scripts 94 KiB (8). Under 2 MB keeps phones on slow connections fast.

2 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.

2 images further down the page (1.1 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

1 image is downloaded at several times the size a phone draws it, for example home_safety.png at 829 px wide, shown at 273 px. Resized copies would save about 2 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.69 g of CO₂e: 82.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

ARIA input fields must have an accessible name: 3 elements on the page fail this check, rated serious by axe-core.

ARIA toggle fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

Some lists contain elements other than list items, which screen readers announce wrongly.

Some list items are not inside a list.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 6 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.

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

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

Headings skip levels (h1 → h6, h2 → h6 and h2 → h6), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 25 characters: “Home | J. Derenzo Company”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.jderenzo.com/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at jderenzo.com/robots.txt, the first file search crawlers ask for.

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

The homepage links to 19 pages on jderenzo.com 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 https://www.jderenzo.com/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.

https://www.jderenzo.com/about, https://www.jderenzo.com/projects, https://www.jderenzo.com/safety, https://www.jderenzo.com/careers, https://www.jderenzo.com/contact and https://www.jderenzo.com/jdc-awarded-excellence-in-safety have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.jderenzo.com/jdc-awarded-excellence-in-safety has no <h1> headline, so visitors and search engines get no clear main topic.

https://www.jderenzo.com/contact and https://www.jderenzo.com/jdc-awarded-excellence-in-safety have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 6 pages linked from your homepage and read each the way a search engine does.

4 images are served at too low a resolution for sharp phone screens.

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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

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 1,093 words of visible text.

Opening the homepage sets 1 cookie (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 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
