deemfirst.com website review

About 535 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.3 s faster on a phone.

7 images could be 441 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.4 s faster on a phone.

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

Your mobile performance score is 55 (desktop: 76). Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Other Google APIs/SDKs and others), adding 1.5 MB and 776 ms of main-thread time.

Google CDN costs a phone 472 ms of main-thread work and 767 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 78 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 2.6 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

13 long tasks block the main thread while loading, the longest for 117 ms. During a long task the page ignores taps.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 50 ms faster on a phone.

6 KiB could be saved by minifying JavaScript.

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.

The first text or image appears after 9.8 s on a phone. Good is under 1.8 s.

Your largest element takes 17.2 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 17.2 s. Good is under 3.8 s.

Visually, the page fills in at 9.8 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 69 ms to 70 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.3 MB in 78 requests on a phone: scripts 1.5 MB (35), images 1.1 MB (18) and other files 350 KiB (4). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.92 g of CO₂e: 110.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 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: 5 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.

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

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

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

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.

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

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

The homepage links to 64 pages on deemfirst.com and 3 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.

/about-us, /latest-news, /recent-job-photos, /services, /services/building-automation and /services/electrical and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 17 found) and read each the way a search engine does.

3 of 11 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 link from your homepage to your own site is broken, for example https://deemfirst.com/?page_id=2261 (404).

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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

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

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.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

deemfirst.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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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.

The homepage has only about 204 words of visible text; thin pages give Google and first-time buyers little to go on.

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

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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.

DMARC is set to p=none, so mail pretending to be deemfirst.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 Analytics 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 4 cookies (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 11 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
