What to expect in the working pack

Start Here
Set the investigation scope, decision question, accountable owner, dates and working rules before changing anything.
Evidence Register
Capture each source, observation, date, owner, confidence limit and evidence gap without turning an assumption into a fact.
Diagnosis
Compare possible causes, record the evidence for and against each one, and identify which failed check needs action.
Action Plan
Assign an owner to each agreed action. Record dependencies, acceptance criteria, release controls and rollback conditions.
Verification
Record production proof, live tests, expected reporting lag, guardrails and the result against the original baseline.
Decision Log
Record the decision to proceed, change, investigate again or stop. Name who authorised it, the remaining risks and the next review date.

How to use it as you follow the guide

Before Section 1
Open Start Here. Name the exact problem, affected scope, decision owner and safe working boundary before gathering or changing evidence.
While working through Sections 1 and 2
Use Evidence Register for source facts and Diagnosis for competing explanations. Keep observations, interpretations and unknowns separate.
During Section 3
Move only the accepted cause into Action Plan. Assign an owner, dependency, acceptance test and rollback condition to every change.
During Section 4
Use Verification to compare the released result with the baseline. Record technical proof and later search or commercial movement as separate evidence.
During Section 5 and close-out
Use Decision Log to record what will proceed, change, reopen or stop. Name who will prevent the problem returning and when they will review fresh evidence.

Working rule: The workbook is a structured investigation record, not a pre-completed diagnosis or performance promise. Keep source evidence, uncertainty and decision authority visible throughout.

Start here

Agree what you need to find out.

Use this guide when you are responsible for resolving the problem described by “organic traffic dropped after website migration”. Check the cause before changing content, technology or the way the work is done.

Before you start

The exact production URL or a tightly related URL sample, including the intended public or private state.
Access to production responses, rendered output and the relevant search-platform evidence.
A named website owner who can authorise exposure, canonical and release decisions.

What you leave with

A dated evidence record for the problem described by “organic traffic dropped after website migration”.
A decision that answers: Identify redirect, content, rendering, tracking or authority losses and prioritise recovery.
An action plan with a responsible owner, live-site evidence, acceptance criteria and a follow-up date. State when to roll back the change or investigate again.

How to run every step

01Record the observation, source, date, scope and evidence owner before drawing a conclusion.
02Classify the statement as VERIFIED, INFERRED, PROPOSED or REQUIRES VALIDATION; do not silently promote an assumption.
03Name the result you need and who is responsible for each step. Record the decision it supports and any question still unanswered.
04After a change, record the live result and acceptance test. Keep source-code, preview and live-site evidence separate.
05Monitor search recovery and business results separately. If a check still fails, investigate that check again before repeating the whole method.

Accountable owner: CMO, Head of Digital or Product Owner
Operating action: check publication, fetching, rendering, canonicals, discovery and search-platform records in order before changing a control
Decision gate: Before making a change, check that the evidence supports this decision: Identify redirect, content, rendering, tracking or authority losses and prioritise recovery.
Acceptance evidence: check the live canonical URL and the search-platform record separately. Assign an owner and review date when reporting has not caught up
Rollback or reopen when: the change exposes a private surface, alters an unrelated canonical, creates a redirect failure or weakens an important user journey
Scope boundary: Post-migration search recovery; it does not promise complete ranking restoration.

After a migration, compare what changed with the search journeys that lost traffic. Investigate URLs, redirects, content, rendering, tracking, canonicals, internal links, infrastructure and demand. Establish the cause before choosing recovery work.

What the problem looks like and why it matters

Symptoms include a step-change in clicks or impressions after launch; old URLs returning errors; new pages excluded or selected as duplicates; important content, headings or links missing; branded demand remaining stable while non-brand landing pages fall; or analytics declining because tags and consent changed rather than visits.

Define the incident window and business exposure. Segment by page type, query class, device, country and conversion path. Do not use the site-wide percentage alone. Assign an incident owner with authority across engineering, content, analytics and commercial teams. Preserve logs, old crawls, exports and build evidence before they expire.

Valid decisions include FIX NOW, ROLL BACK, RESTORE CONTENT, CORRECT REDIRECT, CORRECT TRACKING, CONSOLIDATE, MONITOR, or ACCEPT INTENDED CHANGE. No guide can guarantee complete ranking recovery.

What evidence distinguishes the real cause

Build a timestamped evidence line from before launch through current production:

Evidence stream	Compare
URL inventory	Old canonical URL, intended new URL, final response and redirect chain
Search	Clicks, impressions, queries, pages, indexing reasons and selected canonicals
Content	Title, heading, main answer, evidence, structured data, media and internal links
Rendering	Server HTML, rendered DOM, required resources and error states
Infrastructure	DNS, TLS, host redirects, status/error logs, latency and CDN behavior
Measurement	Tag presence, consent state, event definitions and analytics continuity
Demand	Seasonality, brand/non-brand mix, market events and campaign changes

Use unaffected pages and time-aligned prior periods as controls. A simultaneous analytics and Search Console decline suggests a real exposure more strongly than an analytics-only decline, but attribution still requires inspection. If old URLs never had an accepted one-to-one map, reconstruct it from historical sitemaps, analytics, Search Console, backlinks and archives.

How to fix it step by step

Step 1: Stabilise the incident

Freeze unrelated releases, name the incident owner, capture production and decide whether a rollback remains possible. Stop destructive cleanup until the old/new URL evidence is secured.

Step 2: Quantify affected value paths

Rank affected URL groups by qualified demand, revenue/support journey, external authority and strategic importance. Separate measurement loss from discovery loss. Create a priority cohort small enough to test immediately.

Step 3: Reconcile the URL map

Map each valuable old URL to the closest equivalent new destination. Use direct permanent server-side redirects for durable moves. Avoid blanket homepage redirects, chains and irrelevant targets. Return a real 404 or 410 when content has no replacement and removal is accepted.

Step 4: Restore technical eligibility

For priority targets verify status, robots state, canonical, sitemap inclusion, internal links and rendered main content. Correct accidental noindex, blocked resources, canonical references to old hosts and mixed hostname/protocol behavior.

Step 5: Restore content and task continuity

Compare the old and new page's market task, evidence, copy, media, structured data and next action. Restore material value that disappeared unintentionally. Do not paste old text blindly if the service or product changed; record an accepted content decision.

Step 6: Rebuild internal and external pathways

Update navigation and contextual links to the final new URLs. Correct feeds, sitemaps, hreflang and campaign destinations. For high-value external links, request updates selectively while keeping redirects.

Step 7: Correct measurement separately

Test consent, page views, conversions and lead delivery end to end. Annotate the migration and any tracking-definition changes. Do not claim traffic recovery from an analytics fix without search evidence.

Step 8: Release priority repairs and expand

Deploy and verify the highest-exposure cohort first. When status, canonical, content and measurement checks pass, extend the same accepted rule to the remaining mapped cohort. Submit current sitemaps and monitor recrawl/indexing without promising timing.

How to verify recovery

Implementation is accepted when priority old URLs resolve directly to equivalent new pages, new canonicals and internal links agree, production content is present, sitemaps list final URLs, and measurement passes a real journey test. External recovery is evaluated by cohort: indexed targets, selected canonicals, impressions/clicks, qualified actions and error trends.

Keep recovery and outcome separate. A page can be technically recovered before demand returns; demand can also change independently. Roll back or escalate if priority URLs error, broad rules misdirect users, private content becomes public, or the new experience cannot complete the previous market task.

How to prevent the problem returning

Make the URL map, content parity, technical eligibility, analytics continuity and rollback plan release prerequisites. Crawl and compare production-equivalent builds before cutover. Retain redirects long enough for users and systems that still depend on old URLs, and monitor logs plus Search Console after release.

Google's current site-move guidance, redirect guidance, canonical guidance and crawl-error guidance were reviewed 29 August 2026. They guide implementation but cannot guarantee restoration.

Scope boundary: Post-migration search recovery; it does not promise complete ranking restoration.

Use only the evidence I provide. Do not invent facts, benchmarks, sources, outcomes, customer research or legal conclusions. Keep VERIFIED, OBSERVED, INFERRED, PROPOSED and UNKNOWN separate. Ask focused questions when the evidence or authority is missing.

Help me work through this method by returning:
1. An evidence table with claim, source, date, confidence and limitation.
2. The strongest competing explanations, including what would disprove each one.
3. Decision options with trade-offs, dependencies and the cost of waiting where evidence supports it.
4. The next smallest evidence-gathering action, its accountable owner and acceptance test.
5. A proceed, change, validate, defer or stop recommendation that a named human decision-maker can review.
