The verdict in three sentences
For a Dubai B2B company whose English and Arabic site is slow on mobile, a Core Web Vitals optimisation costs AED 6,000 to AED 35,000 in 2026, depending on the CMS, the number of page templates, Arabic font handling and third party scripts. Google's three targets are clear: LCP under 2.5 seconds, INP under 200 milliseconds, CLS under 0.1, measured on real visitor data. Ask for a line by line quote with working days, and a commitment on field values measured 28 days after delivery.
What the three metrics measure, and the Gulf specifics
LCP measures when the largest visible element appears, often a hero image or product photo. INP measures responsiveness when a user taps a filter, opens a menu or submits an RFQ form. CLS measures layout shifts, such as a button jumping when a font loads or a cookie banner appears.
Dubai sites add two challenges. Arabic web fonts are heavy, often 150 to 400 KB per weight, and right to left layouts can shift when fonts swap, hurting CLS. Visitors also come from across the GCC, India and Europe, so server location and CDN choice matter: a site hosted only in Europe adds noticeable latency for Gulf users on mobile.
| Metric | Good | Needs work | Poor | Common cause on a Dubai B2B site |
|---|---|---|---|---|
| LCP | Under 2.5 s | 2.5 to 4 s | Over 4 s | Heavy hero images, distant server |
| INP | Under 200 ms | 200 to 500 ms | Over 500 ms | Chat widgets, tracking pixels, heavy JavaScript |
| CLS | Under 0.1 | 0.1 to 0.25 | Over 0.25 | Arabic font swap, banners without dimensions |
| Mobile page weight | Under 1.5 MB | 1.5 to 3 MB | Over 3 MB | Uncompressed images, autoplay video |
| Arabic font files | 1 to 2 subset weights | 3 to 4 weights | 5 or more full weights | Full font families loaded on every page |
Line by line quote
The quote below is a 2026 estimate for a B2B distributor with English and Arabic versions and a 2,000 product catalogue, at a day rate of AED 2,400, excluding 5 % VAT.
| Item | Scope | Days | Amount (AED) |
|---|---|---|---|
| Performance audit | Field and lab data, 6 templates, both languages | 1.5 | 3,600 |
| Images | WebP or AVIF, sizing, lazy loading | 2 | 4,800 |
| Arabic and Latin fonts | Subsetting, preload, font display strategy | 1.5 | 3,600 |
| Third party scripts | Inventory of 10 to 40 scripts, removal, deferral | 2 | 4,800 |
| CDN and hosting | Edge caching with a Gulf point of presence, compression | 1 | 2,400 |
| Catalogue and RTL layout | Lighter filters for INP, RTL shift fixes for CLS | 2 | 4,800 |
| QA and 28 day measurement | Field data check, report | 1 | 2,400 |
| Total | 11 | 26,400 |
A 20 page bilingual corporate site without a catalogue often stays between AED 6,000 and 12,000. Multi CMS setups or product configurators can pass AED 35,000.
Recurring costs to plan for
| Recurring cost | Indicative amount | Why |
|---|---|---|
| CDN | AED 0 to 200 a month | Files served closer to GCC visitors |
| Faster hosting | AED 150 to 600 a month | Server response under 600 ms |
| Metric monitoring | Included in Search Console | Alerts when a metric degrades |
| Quarterly check | AED 1,200 to 2,400 | New scripts and pages |
| Site maintenance | Monthly contract, varies by provider | Updates without losing performance |
Once the site is fast, it still has to rank for your buyers' searches. Kolonell offers a visibility audit at 100,000 FCFA (about EUR 152), credited against setup if you start within 30 days, then a 12 month Traffic Engine plan: Presence 125,000 FCFA (about EUR 191), Momentum 225,000 FCFA (about EUR 343) or Flood 350,000 FCFA (about EUR 534) a month, with a 300,000 FCFA setup (about EUR 457) and a weekly report.

Illustrative example, fictional company: Omar, marketing manager at a Dubai distributor of industrial safety equipment, sees a mobile LCP of 4.8 seconds, an INP of 380 ms, a CLS of 0.22 on Arabic pages and 27 third party scripts. The site gets 15,000 visits a month with a 1.0 % RFQ rate, about 150 RFQs.
He signs a quote for AED 26,400. After 28 days, LCP is down to 2.2 seconds, INP to 170 ms, Arabic CLS to 0.05, and 12 scripts are gone. The RFQ rate rises to 1.3 %, 45 extra RFQs a month. At a 12 % close rate and AED 5,000 margin per order, that is about AED 27,000 of extra monthly margin: the work pays back in about a month.
FAQ
What does a Core Web Vitals optimisation cost in Dubai?
AED 6,000 to 35,000 in 2026 depending on size, languages and scripts. A bilingual catalogue site with a few thousand products often lands between AED 20,000 and 28,000.
Why do Arabic pages often fail CLS?
Large Arabic fonts load late and swap in, shifting the right to left layout. Subsetting to 1 or 2 weights and preloading usually brings CLS under 0.1.
Where should the site be hosted?
Use a CDN with points of presence in the Gulf, even if the origin server is elsewhere. That often cuts server response for UAE visitors by 200 to 400 ms.
Do Core Web Vitals alone win rankings?
No, they mostly act as a tiebreaker between equally relevant pages. The clearest gain is often conversion, from 1.0 to 1.3 % RFQs in this example.
How soon will Search Console show the change?
Field data uses a rolling 28 day window, so allow 4 to 6 weeks after launch. Lab tests show the gain immediately.
