deem.com website review

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.4 s.

11 files are served with short cache lifetimes, so returning visitors download them again (115 KiB).

Your mobile performance score is 65 (desktop: 92). Pages that score under 90 lose visitors before the first paint.

About 134 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

About 125 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

website-files.com costs a phone 195 ms of main-thread work and 611 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.

5 images could be 238 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

8 third-party services load with your homepage (website-files.com, Optanon and cloudfront.net and others), adding 894 KiB and 355 ms of main-thread time.

Polyfills for old browsers add 20 KiB JavaScript that modern phones do not need. 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 50 ms).

1 long task block the main thread while loading, the longest for 50 ms. During a long task the page ignores taps.

Desktop scores 92 but mobile only 65. A gap that wide usually means heavy scripts and images that hit phones hardest.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

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 8.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “BUSINESS TRAVEL SOFTWARE THAT MAKES IT EASIER TO TRAVEL ANY…”.

The first text or image appears after 4.1 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 8.3 s. Good is under 3.8 s.

Real visitors wait 2.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 822 ms for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.4 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 71 ms to 70 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

65eb29680d12d4928f6a6f2a_Banner-CIty-mobile-p-500.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 further down the page (26 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.31 g of CO₂e: 36.6 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.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

Banner landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Elements with visible text labels do not have matching accessible names. (16 elements).

There are 13 <h1> headlines (“Business travel software that makes it easier to …”, “The Champ is Here” and “Business travel software that makes it easier to …”). One clear main headline is easier for people and search engines.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

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

The homepage links to 110 pages on deem.com and 11 external pages.

Your Organization JSON-LD is missing logo, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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.

We fetched 15 pages linked from your homepage (of 41 found) and read each the way a search engine does.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

1 link from your homepage to your own site is broken, for example https://www.deem.com/how-to-video (404).

2 links to other sites are dead, for example https://support.travelport.com/webhelp/deem/Content/Start/Video.htm (404).

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

1 link go through two or more redirects, for example https://www.travelport.com/deem.

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.

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

deem.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.

deem.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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Social proof on the homepage: 6 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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

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 545 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.

Opening the homepage sets 5 cookies (measured from a US location before any click).

Loading the homepage contacts 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
