Tools and automation

What everything else stands on: Telegram, market research, CRM, dossiers, documents, mail, leads.

  • One supplier inbox

    internal tool
  • Forms and leads

    Form on the page → server intake → Telegram bot for the manager → CRM record. I used to rewrite lead delivery on every site and counted six different implementations; now a new site gets it as a ready module.

    internal tool
  • pvz.bz — Council of geniuses

    Verbatim texts of five people with sources: DHH, Jason Fried, Anton Gladkov and others. The agent answers only with quotes.

  • Chrome extensions

    Three extensions: a message queue for any web chat with quiet hours and retries, outreach to contacts in Telegram Web, and a helper that drafts replies to people who have already written and are waiting.

Advertising and growth

Search advertising from brief to import file, landing pages and traffic.

  • it4.biz

    A Direct and Google Ads search campaign — from brief to import file

  • lll.bz

    A landing page or site for $700–1,200 — and traffic to it

  • Yandex Direct: a standard and a campaign builder

    One campaign standard for any site, distilled from 70-plus versions of real campaigns: how to build keywords and negatives, how to split groups by intent, how to write combinatorial ads. The builder turns a spec into an import workbook, and the validator checks it against Direct’s limits before upload. Wordstat via API suggests long-tail keywords, and the search-query report is tagged by the site’s own rules — new groups and negatives go into the next version. Every version is kept separately; old ones are never rewritten.

    internal tool
  • Google Ads: a search campaign builder

    The same path as in Direct, for Google: brief → keywords by intent → responsive search ads (up to 15 headlines and 4 descriptions) → negatives → a CSV for Google Ads Editor plus a note on what to set by hand. Checks catch limit overruns, duplicate keywords and negatives that would block your own keywords. The negative list is shared with Direct. Reports on search terms, keywords and ads — from the account or via API — become a summary and a list of edits for the next revision.
