- Qualified leads
42Aval handles full-stack accounting for small and mid-size businesses. Their old site loaded in 5+ seconds, ranked nowhere on Google, and the contact form was the only conversion path.
The problem
- Site loaded slowly on mobile, dropping 60% of paid traffic before the page rendered.
- Zero structured pages for service categories — Google had nothing to index.
- No lead qualification — every form went to one inbox without context.
The solution
- Rebuilt as a Next.js multi-page site with SSR and SEO-tuned service pages.
- Added an interactive cost calculator that pre-qualifies leads before contact.
- Wired Yandex.Direct + Google Ads with conversion tracking and Telegram notifications.
The outcome
In 4 months: 312% growth in qualified leads, 0.9s LCP on mobile, and ~100/100 PageSpeed across the site.
