Resource hints (preload / preconnect / prefetch)
We set up resource hints — tips to the browser on what to load earlier: preload for critical resources, preconnect for early connections to third-party domains, dns-prefetch, prefetch for likely next pages. So important things load with priority and faster. Honestly upfront: this gives a modest, targeted win, but careless use (over-preloading) can HARM — so we do it selectively and measure.
Resource hints (preload / preconnect / prefetch) — overview

Resource hints is a project: we analyze the critical loading path and place browser hints — preload for key first-screen resources (font, hero image, critical script), preconnect/dns-prefetch for early connections to third-party domains (analytics, fonts, CDN), and prefetch of likely next pages where appropriate. Honestly about the effect and measure, this is key: hints are a TARGETED tool with a modest win (important things start loading earlier), NOT a magic speedup of the whole site; and MEASURE matters — over-preloading (when too much is marked 'priority') competes for bandwidth and can SLOW the main load, and extra preconnects waste resources; so we mark selectively and check 'before/after'. Honestly about limits: hints only change loading priorities/timing, but do not reduce resource weight or cure a slow server (those are separate tasks). Honestly about business: speedup helps UX/metrics, we do NOT guarantee sales growth by itself. Honestly about access: access to code/templates is needed. An important boundary: these are resource hints, not content optimization (706-710), not a CDN (713) and not server cache. If the site is light and fast, the win is minimal. Picture this: instead of 'the browser learns of a critical font/image late' it starts loading important things at once — but without harmful overload. The base price starts from 9,000 ₽ per project; it depends on the number of resources.
Problems we solve
- The browser learns of critical first-screen resources late.
- Connections to third-party domains are established with delay.
- There is no prioritization of the important during loading.
- Chaotic or excessive hints instead of thought-out ones.

FAQ
Will resource hints greatly speed up the site?
It is a targeted tool with a modest win (important things start loading earlier), not a magic speedup of everything. Hints change loading priorities but do not reduce resource weight or cure a slow server — those are separate tasks.
The more preload, the better?
No, on the contrary it is harmful. Over-preloading makes everything compete for bandwidth and can slow the main load; extra preconnects waste resources. So we mark selectively and check the effect 'before/after'.
Will it raise sales?
Not directly guaranteed. Speedup helps UX/metrics, but sales depend on many factors. It is a small technical win, not a promise of revenue growth.
