2. One-sentence definition
Netsujo SIGNAL is a web sales improvement platform for B2B technology and professional-services companies. It identifies where sales opportunities are being lost across search, generative AI, and the company website, and turns that into improvement work an existing web agency can implement.
Each improvement is delivered with the target URL, what changes, the completion condition, and how to verify it.
3. Who this is for
The primary audience is B2B technology and professional-services companies. Typical industries:
- B2B SaaS
- AI
- Web3
- System development
- Digital transformation support
- Technical services in manufacturing
- Specialist consulting
- Licensed professional services
Requests this service does not fit
- A guarantee of search rankings.
- A guarantee of inquiry volume or revenue.
- Bulk article generation on its own.
- Purchased backlinks.
- Advertising operations on their own.
- A full design overhaul on its own.
4. Problems addressed (situations this commonly applies to)
- There is no dedicated SEO owner in-house.
- It is hard to give a web agency instructions that are specific enough to act on.
- GA4 and Search Console are open, but they do not lead to a decision about what to do next.
5. What the service does — five stages
Work is managed as one causal chain, from observing a symptom to verifying the result after publication.
- OBSERVE — observe the symptom
- Inputs: the public site, Search Console, GA4, how the company appears in AI search, and company-specific business information. Outputs: the symptom, affected URLs, a baseline, and the business impact.
- TRACE — locate the implementation cause
- Checked: HTTP status and redirects, initial HTML versus the rendered DOM, metadata and canonical, robots.txt and sitemap, JSON-LD structured data, JavaScript dependencies, internal links, and CTAs, forms, and measurement events. Outputs: confirmed facts, the underlying cause in code or configuration, a confidence level, and the scope of impact.
- SPECIFY — convert into an improvement specification
- Outputs: the target URL, the target component or setting, what changes, why, the completion condition, the verification method, the recommended owner, the expected effort, and the success metric.
- EXECUTE — move the implementation forward
- Customer approval, owner and deadline, hand-off to the existing web agency, resolution of questions and specification gaps, and — within the contracted scope — code examples, diffs, or pull requests.
- VERIFY — confirm publication and outcome
- Production reflection, layout regressions, HTML and metadata, structured data, redirects and canonical, GA4 events, period comparison in Search Console and GA4, and the decision on what to improve next.
