Open your website right now on a mobile phone. Time how long it takes from tap to full page load. If it's 1–2 seconds — great, this article isn't for you. If it's 3–5 seconds — you have a problem, and it's costing your business money every day. If it's more than 5 seconds — you're losing not just occasional leads, but half of all potential customers, every single day, without even knowing it.
In 2026, website loading speed is not a "programmer's technical whim." It's a concrete factor directly affecting revenue, Google rankings, brand perception, and advertising costs.
The math of losses from a slow website
Google has published data on how loading speed affects user behavior. Here's the picture:
Probability of user bounce depending on page load time
In commercial terms: each second of delay reduces conversion by roughly 7%. This is data from Amazon, Walmart, Booking — large services that publicly shared results from their own experiments.
Say a website gets 5,000 unique visitors per month with a 3% conversion rate (150 leads). Average order value — 50,000 tenge. That's 7.5 million per month. If the site loads in 5 seconds instead of 1.5 — that's a 3.5-second difference. At minus 7% per second, you lose 24% of conversions. That's 36 leads per month and 1.8 million tenge in lost revenue. Over a year — 21.6 million tenge. Simply because the site is slow.
And this doesn't account for indirect effects: lower Google rankings due to poor Core Web Vitals, higher cost-per-click due to reduced "landing page quality" in Google Ads and Yandex Direct, and fewer returning visitors.
Mobile traffic: where Kazakhstani websites lose most of their customers
What's typical of a "responsive but not mobile-first" website:
- Heavy images not optimized for small screens. Load times of 5–10 seconds.
- Forms aren't optimized: fields too small for fingers, no automatic keyboard switching for field type.
- Header and footer take up a third of the screen, barely any content is visible.
- Buttons placed awkwardly — difficult to tap with a finger.
A parallel problem: mobile networks. Outside of Kazakhstan's city centers, 4G coverage is unstable and 5G is just being rolled out. A site that loads in 3 seconds on good WiFi takes 8–10 seconds on a slow mobile network. If the architecture isn't optimized — it's a disaster.
Why Tilda and WordPress are slow
Core Web Vitals: measurable speed that affects Google
Google introduced three key metrics that affect search rankings. You can check them for free via Google PageSpeed Insights. On most Tilda and WordPress sites without serious optimization — all three are in the red zone.
- LCP (Largest Contentful Paint) — time to render the largest visible element. Goal: under 2.5 seconds.
- INP (Interaction to Next Paint) — delay between user action and site response. Goal: under 200 ms.
- CLS (Cumulative Layout Shift) — visual stability: when images load and shift the text. Goal: under 0.1.
What actually speeds up a website in 2026

How speed affects advertising costs
A point many overlook. Google Ads and Yandex Direct use "landing page quality" as one of the factors in cost-per-click. The worse your Core Web Vitals and user experience — the more expensive every paid ad click becomes.
Speed is our baseline standard, not an option
Amanix has been doing custom website development for businesses in Kazakhstan since 2023. What we do by default on every project:
- SSR via Nuxt 3 for all public pages
- Image optimization with auto-conversion to WebP and lazy loading
- Minification and gzip compression of CSS, JS, HTML
- Code splitting by page
- Redis caching for frequently-requested data
- HTTP/2 and HTTP/3 in server configuration
- Servers in Kazakhstan data centers for minimal network latency
