Core Web Vitals optimization
We optimize Core Web Vitals — the key page speed and stability metrics (LCP, INP, CLS): we speed up main-content loading, responsiveness to actions and remove layout 'jumps'. So the site feels fast and passes Google's checks. Honestly upfront: we measurably improve the metrics, but speed is a ranking factor, NOT a guarantee of higher positions or sales, and the achievable result depends on hosting, CMS and third-party scripts.
Core Web Vitals optimization — overview
Core Web Vitals optimization is a project: we measure current metrics in the lab (Lighthouse) and in the field (real users/RUM), find bottlenecks and improve LCP (fast main render), INP (input responsiveness) and CLS (layout stability) — critical-path optimization, images/fonts, lazy loading, eliminating blocking resources, handling third-party scripts. Honestly about the essence and limits, this is key: we improve the metrics measurably (showing 'before/after'), but 'green' CWV are 'good' THRESHOLDS, not a guarantee and not a fixed 'Lighthouse 100'; field data of real users varies (devices, networks), and the lab score ≠ field. Honestly about the business effect: CWV is one of the ranking and UX factors, but NOT a guarantee of higher positions, conversion or sales — many things affect those (content, demand, competition); we do not promise '+X positions'. Honestly about limits: the achievable result is limited by hosting, CMS/theme and third-party scripts — on cheap shared hosting or a heavy CMS the ceiling is lower, some things cannot be fixed without changing hosting/architecture; we indicate this honestly. Honestly about regression: as content/plugins/scripts are added the metrics degrade — a one-off optimization is a snapshot, keeping it needs discipline/monitoring (separate). Honestly about access and risk: access to code/server is needed; aggressive optimization can break things — we do it carefully, with checks. An important boundary: this is CWV optimization, not CWV monitoring (separate), not redesign and not changing hosting. If the site is already fast, the benefit is small. Picture this: instead of 'a red PageSpeed report and jumping layout' you get measurably better metrics with a clear 'before/after'. The base price starts from 25,000 ₽ per project; it depends on the site state and platform.
Problems we solve
- Red Core Web Vitals and slow loading.
- The layout 'jumps' during load (poor CLS).
- The site lags on response, especially on mobile.
- Google flags speed problems in Search Console.

FAQ
Will CWV optimization raise my positions and sales?
Not guaranteed. CWV is one of the ranking and UX factors, but many things affect positions and sales (content, demand, competition). We measurably improve the metrics; we do not promise '+X positions' or sales growth.
Do you guarantee Lighthouse 100 / green CWV?
No. 'Green' are 'good' thresholds, not a fixed score; the achievable result depends on hosting, CMS and third-party scripts, and field data of real users varies. We honestly show the achievable maximum for your case.
Will the result last forever?
No. As content, plugins and scripts are added the metrics degrade. A one-off optimization is a snapshot; to stay fast you need discipline and CWV monitoring (a separate service).
