21online.co.za website review

Your mobile performance score is 74. Pages that score under 90 lose visitors before the first paint.

2 third-party services load with your homepage (Wix and Sentry), adding 1.4 MB and 454 ms of main-thread time.

Wix costs a phone 444 ms of main-thread work and 1.4 MB 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 133 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

31 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 150 ms faster on a phone.

2 images could be 11 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

1 long task block the main thread while loading, the longest for 51 ms. During a long task the page ignores taps.

About 32 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 12 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 9.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “ChatGPT Image May 22, 2026, 08_44_19 AM.png”.

The page becomes fully interactive after 9.8 s. Good is under 3.8 s.

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 2.3 MB in 212 requests on a phone: scripts 958 KiB (96), other files 707 KiB (90) and fonts 258 KiB (7). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example 0582a1_45abd27eb144487e809c3b33ba6abd21~mv2.png at 2,501 px wide, shown at 52 px. Resized copies would save about 78 KiB.

1 image (78 KiB) is 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 0.64 g of CO₂e: 77.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Headings skip levels (h2 → 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.

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

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 49 pages on 21online.co.za and 12 external pages.

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

/home, /marketing, /campaign, /digital-artwork, /print-artwork and /resource-packs and 7 others all use the title “21Online | South Africa | Mauritius”. Search engines can't tell which page to show for a search, so each competes with the others.

/home, /marketing, /campaign, /digital-artwork, /print-artwork and /resource-packs and 7 others have no meta description, so Google writes the search snippet from whatever text it finds.

/home, /marketing, /campaign, /digital-artwork, /print-artwork and /resource-packs and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

/home, /marketing, /campaign, /digital-artwork, /print-artwork and /resource-packs and 7 others 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 13 pages linked from your homepage and read each the way a search engine does.

5 of 7 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “globalThis.defineStrictProperty is not a function”.

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.

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.

21online.co.za 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.

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

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

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 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 269 words of visible text.

21online.co.za has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

21online.co.za has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

21online.co.za has no MX record, so it receives no email. SPF -all and DMARC reject still matter: they stop others sending mail as you.

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 7 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 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
