01 / PROBLEM

A rebrand can look finished and still be wrong.

A new identity may already be live while traces of the previous brand remain hidden across legal pages, domains, email identities, metadata, canonicals, structured data and migration files.

The visible rebrand may be complete. The migration may not be.

02 / DISCOVERY

I wasn't looking for another website audit tool.

The research focused on three questions: who owns the problem, when it becomes most expensive, and why existing site-audit tools do not fully address it.

WHO

Branding, web and SEO agencies

Teams responsible for delivering a rebrand or website migration.

WHEN

After implementation, before handoff

The point where a small leftover can create disproportionate doubt.

GAP

Website health ≠ migration completeness

Most crawlers optimize for technical health, not identity residue.

OPPORTUNITYMigration-specific QA + evidence + client-ready reporting
MARKET GAP

Website health and migration completeness are different questions.

GENERIC SITE CRAWLER
  • Broken links
  • HTTP errors
  • Missing metadata
  • SEO health
  • Technical page issues
REBRANDCHECK
  • Legacy brand references
  • Old domain residue
  • Previous email identities
  • Outdated metadata
  • Structured-data leftovers
  • Migration-specific evidence

A crawler tells you whether the website works. RebrandCheck asks whether the old identity is actually gone.

03 / PRODUCT DEFINITION

From brand change to verifiable handoff.

I translated the problem into a four-part model: define what changed, inspect where the old identity can survive, structure each finding, and convert the result into a deliverable.

01 / INPUT

What changed?

VALIDATE FIRST

Will agencies care enough about this problem to request an audit and use the result?

V0 INCLUDED

The first product decision was what not to build.

05 / WORKFLOW

A three-step workflow for migration QA.

01INPUT

Tell us what changed

Brand names, domains, email identities and known migration context.

02CHECK

Run migration QA

Pages, links, metadata, canonicals, schema and sitemap.

03OUTPUT

Fix and prove

Findings, evidence, expected state, actions and a verification report.

06 / INFORMATION DESIGN

An issue is only useful when someone knows what to do next.

A simple “legacy brand found” alert creates another investigation task. Each finding answers six questions immediately: severity, location, detected value, expected state, evidence and recommended action.

CRITICAL/privacy

Legacy legal entity reference

07 / REPORT DESIGN

Designing evidence, not just alerts.

The report had to help designers, developers, project managers and clients understand what remained, what mattered most and what should be fixed.

PRIORITY

What should be fixed first?

Severity creates a clear order of attention.

EVIDENCE

Why was this flagged?

The report keeps the underlying proof attached to the issue.

EXPECTED STATE

What should replace it?

The target value reduces ambiguity during implementation.

ACTION

What happens next?

Recommended steps turn diagnosis into execution.

08 / UI SYSTEM

Dense information, designed to stay readable.

09 / DELIVERY

From product definition to production.

I used an AI-assisted development workflow to turn the product model and interface system into a working validation MVP. AI accelerated implementation while product structure, interaction decisions, visual system and QA remained design-owned.

AI was implementation leverage, not a substitute for product decisions.
RESEARCH→PRODUCT→UX→UI→BUILD→QA→LIVE
10 / QUALITY ASSURANCE

Design didn't stop at handoff.

The validation MVP was reviewed as an end-to-end experience rather than only a set of interfaces.

11 / VALIDATION

Shipped.
Now testing demand.

The MVP is live. The next phase is deliberately manual: reaching out to agencies, running early audits and observing which findings they value enough to act on.

Pilot auditsManual deliveryDirect agency outreachNo signupNo credit card
The next question is not whether the product can be built. It is whether agencies care enough to use it repeatedly.
MARKET VALIDATION IN PROGRESS
12 / REFLECTION

What the first version clarified.

LEARNED

The strongest value may not be detection alone. It may be making migration completion visible, explainable and provable.

NEXT

Automate only the checks that repeatedly prove useful during real agency audits.

STILL UNKNOWN

Usage frequency, willingness to pay and whether agencies prefer per-audit delivery or an ongoing workspace.

Build less. Learn faster. Automate what earns the right to exist.
