demac.com website review

17 files are served with short cache lifetimes, so returning visitors download them again (1.1 MB).

About 312 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

2 images could be 179 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

Google CDN costs a phone 119 ms of main-thread work and 349 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.

4 third-party services load with your homepage (Google CDN, Google Tag Manager and Other Google APIs/SDKs and others), adding 508 KiB and 189 ms of main-thread time.

3 long tasks block the main thread while loading, the longest for 141 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 11 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.

3 KiB could be saved by minifying JavaScript.

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.

Your largest element takes 9.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “One hundred countries. Six continents. Thirty-one languages…”.

The first text or image appears after 4.7 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 9.2 s. Good is under 3.8 s.

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

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.5 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

3 images (803 KiB) 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.47 g of CO₂e: 55.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 images have no alt text, which hurts accessibility and image search.

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.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

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.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your meta description is 222 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.

3 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

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

The homepage links to 53 pages on demac.com and 1 external page.

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.

/es, /fr, /ru, /kk, /ar and /zh all use the title “DeGolyer & MacNaughton | World Wide Petroleum Consultants | DeGolyer …”. Search engines can't tell which page to show for a search, so each competes with the others.

/es, /fr, /pt, /ru, /kk and /ar and 9 others use the same meta description. A description written for each page earns more clicks.

/es, /fr, /pt, /ru, /kk and /ar and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

/ru, /kk, /ar, /zh, /reference-materials and /reference-materials/oil-gas-prices 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 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

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

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

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.

demac.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.

demac.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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 210 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

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 3 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
