Tech Blog

A technical blog where we publish practical knowledge from building Web3, blockchain, and AI systems, written for IT engineers. We share first-hand accounts of the problems we ran into during implementation, design decisions, and verification results.

For a systematic guide to Web3, see our Web3 Knowledge Hub; for talks, events, and other activity reports, see our blog. Both are currently Japanese-only, along with the articles listed below.

Recent article themes

Our Tech Blog groups articles under themes including AIO (AI search visibility and optimization — how a site is found and cited by AI assistants and AI-generated search answers), SEO, and AI development. Recent themes include: how to select an AIO / AI-search vendor, the cost of AIO work, why strong technical capability often fails to come across on the web, checking whether AI crawlers are reaching a site via server logs, whether a JavaScript-rendered site's content reaches crawlers, comparing how much AIO work is possible on different CMS platforms, why AI search tends to recommend competitors instead of your company, why AI sometimes gets company information wrong and how to fix it, what an AIO diagnostic can and cannot tell you, measuring SEO/AIO results through to enquiries, an AI-search-engine optimization guide, AI writing and SEO quality, structured data (Schema/JSON-LD) implementation, and an AI Overviews guide.

Other recurring themes include GSC-driven content rewriting, whether to block AI crawlers such as OAI-SearchBot and GPTBot, E-E-A-T for B2B sites, how to identify search intent, local SEO/MEO basics, AI-driven local discovery, review and rating strategy, e-commerce product-page SEO/AIO, growing branded search, mobile UX and Core Web Vitals, and how to choose an SEO or web-production partner.

On the AI-development side, we have published write-ups on connecting business tools to AI agents via MCP (Model Context Protocol), keeping structured data intact across Next.js and Strapi, tracking AI citations, running RAG (retrieval-augmented generation) in production, running our own AI-agent operations ("Netsujo's operating OS"), building an in-house SEO analytics dashboard that combines GA4 and Search Console, and our record of spec-driven development and parallel project work with Claude Code.
