GTM Ultimate Stack

Inventory, audit and trace tags, triggers and variables, then clean up and roll out changes across every container you manage.

Start here · Complete guide

Run GTM across every container from one screen

The complete guide to the ODDVX GTM modules: inventory and clean up every container, check them against your standards, and see what depends on what before you change it, across every brand you manage.

3 modules

Module · Complete guideInventory & CleanupEvery tag, trigger and variable across your containers, cleaned up and rolled out in reviewed batches.12 task guides
Complete guideManage GTM across every brand from one tableThe complete guide to ODDVX Inventory & Cleanup: extract every tag, trigger and variable across your brands, clean up with evidence, and build a change once to stage it in every container. Publishing stays with you.Read the module guide

See

  1. 01Inventory every tag, trigger and variable across your brandsExtract a complete GTM inventory for one brand or a whole portfolio in one pass, narrow it to the question that matters, and leave a record the next owner can repeat.Practical guide
  2. 02In use, only inactive users, orphaned: reading GTM usage verdictsWhat each usage verdict means for tags, triggers and variables, why it differs from paused status, and why an orphaned item is a question to answer rather than a deletion to make.Interpretation guide

Clean

  1. 03Clean up orphaned triggers and variables across brands in one batchFilter every container to its orphaned triggers and variables, stage the deletions you can justify, review them per container, then publish and verify, in rounds.Practical guide
  2. 04Pause, delete or retain a GTM tag?Use purpose, timing and verification to choose the right action for a cleanup candidate, then stage it in one container or in every brand that shares it.Decision guide
  3. 05Apply a naming convention across every brand with find & replaceTurn a naming rule into a precise selection, preview the new names, and stage one reviewed rename across every container that needs it.Practical guide

Build

  1. 06Create the same tag, trigger or variable in every brand at onceFill in one GTM-style form, choose every container that needs it, and stage the new tag, trigger or variable in each one for review. Publishing stays with you.Practical guide
  2. 07Copy a working setup from one brand to the restCopy a proven tag, trigger or variable into other containers together with the triggers and variables it depends on, reusing what already exists instead of overwriting it.Practical guide
  3. 08Roll out a Community Template tag to every containerCopy a tag built on a Community Template Gallery template into other containers, with the template installed where it is missing and reused where it is already present.Practical guide
  4. 09Swap a vendor tag across brands in one reviewed batchReplace an old vendor tag in every brand by staging the new tag, pausing the old one and marking it retired, all in a single reviewed batch, then retire it for good once the new one is verified.Playbook

Control

  1. 10Read the Review & apply preview before anything is writtenUnderstand the dry-run preview: what each outcome means in every container, how to fix skipped items, and how the workspace options decide where your changes land.Practical guide
  2. 11Workspaces, publishing and recovery for multi-brand changesHow ODDVX stages a change into a named workspace in every container, how to publish safely brand by brand, and how to resume or roll back when something goes wrong.Practical guide

Repeat

  1. 12Schedule a recurring orphan and hygiene report across brandsSave an inventory extract and its filters as a recurring report, so orphaned and off-convention items surface on schedule without anything being changed.Practical guide
Module · Complete guideStandardization AuditNaming and config checks against built-in standards, plus your own.9 task guides
Complete guideCheck every GTM container against your standardsThe complete guide to ODDVX Standardization Audit: check every container against built-in and custom standards for consent, GA4 configuration, naming and tag hygiene, read the findings per container, and know where each one gets fixed.Read the module guide

Run

  1. 01Run your first GTM standards audit across every brandPick the brands, check which standards are on, run one read-only audit across every container, and know exactly what it read before you trust the result.Practical guide
  2. 02Read a GTM standards audit scorecardWhat pass, fail and n/a mean, how severity orders the containers, what a finding tells you, and why the standards that fail most often matter more than any single finding.Interpretation guide

Set standards

  1. 03Tune the built-in GTM standards to your house rulesThe 18 standards ODDVX ships, which are on from the start, which need your convention first, and how to switch, edit, delete and restore them.Practical guide
  2. 04Write your own GTM standardTurn a house rule into a standard: choose what it applies to, pick one of 14 checks, set the severity, and read it back as a sentence before you save.Practical guide

Check

  1. 05Check consent settings on every GA4 and ads tagUse the consent standards to find the tags that don't declare the consent types they need, container by container, before a client's privacy review does.Practical guide
  2. 06Check GA4 configuration in every GTM containerFind containers with two GA4 configuration tags, Measurement IDs typed into tags, leftover Universal Analytics tags and event parameters that won't match your GA4 reports.Practical guide
  3. 07Enforce a GTM naming convention across every brandTurn your naming convention into standards, find every name that breaks it in every container, and fix them in one reviewed rename.Practical guide

Fix & repeat

  1. 08Turn GTM standards findings into fixesThe audit only reads, so every finding is fixed somewhere else. Where each kind gets fixed, how to batch the fixes across containers, and how to confirm they worked.Practical guide
  2. 09Schedule a GTM standards auditRun the standards audit every week across every brand and get the results by email, so a new brand or a quick fix that broke the convention shows up before the next client review.Practical guide
Module · Complete guideTag Dependency MapSee what depends on what before you change it.6 task guides
Complete guideSee what depends on what in a GTM containerThe complete guide to ODDVX Tag Dependency Map: search any tag, trigger, variable or dataLayer event, see everything that leads to it and everything it leads to, and know what a rename, pause or delete will touch before you make it.Read the module guide

Map

  1. 01Map a GTM container's dependenciesLoad a GTM account, switch between its containers, search for any item and follow its links upstream and downstream, one click at a time.Practical guide
  2. 02Read the links in a GTM dependency mapWhat fires, blocks, listens for and uses mean, where dataLayer events come from, why built-in variables appear, and what an item with no links is telling you.Interpretation guide

Before a change

  1. 03Check what breaks before you delete or pause a GTM itemBefore a delete or pause, map the item: confirm nothing depends on it, or see exactly what would break and decide what to do first.Practical guide
  2. 04Trace a dataLayer event to every tag it firesSearch a dataLayer event name to see every trigger listening for it, every tag those triggers fire and every variable those tags read, before a developer renames or removes it.Practical guide
  3. 05Find everything that reads a GTM variable before you change itSearch a variable to list every tag, trigger and variable that reads it, follow chains through lookup tables, and know what a change to its value will reach.Practical guide

Share

  1. 06Export a GTM tag's full lineage for reviewBuild an export selection, preview each item's full lineage, and send it as an Excel or HTML file to whoever signs off the change.Practical guide

  2. 02Check every GA4 property against your settings standardSave your agreed GA4 settings as a baseline, compare every property against it instead of against each other, and keep one baseline per region or client type on Premium.Practical guide

Change

  1. 03Change a GA4 setting on many properties in one reviewed batchStage changes by value, from a reference property or from a baseline, preview them against live GA4, and apply them with a read-back, so a portfolio-wide settings change is one reviewed batch.Practical guide
  2. 04Standardise GA4 attribution settings across brandsCompare the reporting attribution model, both conversion lookback windows and the Google Ads export scope on every property, then align them knowing which changes re-credit past data.Practical guide
  3. 05Set GA4 data retention on every property without losing dataFind the properties still on GA4's 2-month default, raise event and user retention across brands, and know which changes delete data and need typed confirmation.Practical guide
  4. 06Align enhanced measurement and data redaction on every web streamCompare enhanced measurement events and email and query parameter redaction stream by stream across every property, then switch them on or off in one reviewed batch.Practical guide

Module · Complete guide coming soonChannel Groups VaultOne channel taxonomy, rolled out to every property.2 guides

The complete guide to Channel Groups Vault is in production. Its guides so far:

  1. 01Roll out one channel group taxonomy to every GA4 propertySee every property's channel groups in one coverage matrix, save an agreed taxonomy as a template, and apply it across properties with a per-property diff before anything is written.Practical guide
  2. 02Why channel order decides your GA4 traffic numbersGA4 gives each session to the first channel that matches, so the order of channels in a group changes the numbers. Learn to read, test and change the order safely.Interpretation guide
Module · Complete guide coming soonDimensions Control CenterCustom dimensions registered everywhere, and checked for real values.2 guides

The complete guide to Dimensions Control Center is in production. Its guides so far:

  1. 01Register a GA4 custom dimension on every property at onceMake an event parameter reportable across your portfolio: choose the properties, register the dimension once with a per-property dry run, and keep names consistent.Practical guide
  2. 02Check that GA4 parameters are populated on real trafficA registered dimension isn't proof the data is there. Validate parameters across properties, read each status, set a sensible tolerance and find what's behind a failure.Practical guide

Across every module

  1. 01Schedule GA4 checks that only email you when something is wrongTurn anomaly scans, parity checks and performance pulls into recurring reports across every brand, with anomaly emails that stay silent on clean days.Practical guide
  2. 02GA4 change control: previews, records and recoveryGA4 has no workspace and no publish step, so changes are live once confirmed. How to preview, roll out, record and reverse GA4 changes safely across properties.Practical guide

QA Ultimate Stack

Specify, test and prove tracking from the dataLayer push to the delivered hit: forms, network requests, CSP, page speed and release QA across every brand.

Start here · Complete guide

Debug tracking end to end, from the page to the hit

The complete guide to tracking QA with ODDVX: write the dataLayer spec, check live pages against it, prove real form conversions, confirm every hit was delivered and measure what tags cost in page speed.

Specify

  1. 02Write a dataLayer specification your brands can be checked againstBuild one shared template of events and parameters, describe nested and array values in a flat table, keep separate templates for different kinds of site, and hand developers a spec they can implement.Practical guide
  2. 03Track each brand's dataLayer implementation statusRecord, per brand and per event, whether the spec is not started, in progress, implemented, verified or not applicable, with a note and a date, so the rollout has one source of truth.Practical guide

dataLayer

  1. 04Check a live page's dataLayer against the specCapture a page's real dataLayer by scanning the URL or pasting from DevTools, scope the check to the events that page should fire, and read matched, missing and unexpected events key by key.Practical guide

Forms

  1. 05Set up a synthetic form test: fields, steps and test valuesRead a live form's fields the way a screen reader does, build the steps, use obviously fake test values, check required fields without submitting, and set what the run must observe.Practical guide
  2. 06dataLayer, tag hit, cookie: the three layers of a form testA form test checks three independent facts. Learn what each layer proves, why a passing dataLayer can hide a broken tag, how listeners survive page navigation, and how cookies and duplicate fires are judged.Interpretation guide
  3. 07Run real form submissions safelyValidate without submitting, submit only with explicit confirmation, keep test hits out of GA4 with Anonymous Run, get past bot protection with an agreed header, and agree the CRM clean-up before the first run.Practical guide
  4. 08Read form test results: never observed, params missing, fired more than onceWhat each form test result means, how to tell a site problem from a tag problem from a config problem, and what the run records to help you decide.Interpretation guide

Delivery

  1. 09Inspect every GA4 collect request a page sendsThe DevTools "filter collect" check, automated: record every client-side and server-side GA4 request a page sends, with full headers and a payload decoded into its individual events.Practical guide
  2. 10Delivered, blocked or warned: reading a hit's delivery verdictA tag that fired is not proof the hit arrived. What each delivery verdict means, why an aborted beacon is usually fine, and why a page that sends nothing fails the run.Interpretation guide
  3. 11Find tags blocked by a Content Security PolicyA CSP block stops a hit before it reaches the network, so most tools never show it. See which requests the site's policy blocked, which directive applied, and how to fix and test the policy.Practical guide
  4. 12Check ad-platform pixels and console errors alongside GA4See Google Ads, Floodlight, Meta, TikTok, Microsoft Ads, LinkedIn, Pinterest, Snap and Taboola beacons with the same delivery and CSP checks as GA4, and read the console errors that explain a failure.Practical guide
  5. 13When the test machine itself blocks the tagsA security or ad-blocking tool on the computer running the test can quietly swap the Google tag library for a stub, so the page sends nothing. How ODDVX flags it, and what to do before trusting a zero.Troubleshooting guide

Speed

  1. 14Measure page speed and Core Web Vitals for the pages that matterMeasure LCP, CLS, FCP, TTFB and load time on saved pages, wait for the page to genuinely settle, repeat runs for a reliable median, and read lab numbers for what they are.Practical guide
  2. 15See how long each Google tag takes to load, client-side and server-sideTurn on Google tag checks in a page config to time gtm.js, gtag.js, GA4 collect and Google Ads requests, see when each loaded after navigation, and compare client-side with server-side setups.Practical guide

Operate

  1. 16A tracking QA run for every releaseCombine the spec, parity, form tests, delivery checks and page speed into one repeatable release check, run before and after deployment, with a sign-off record.Playbook
  2. 17Schedule tracking QA that fails loudlyTurn delivery checks, form validations and page-speed tests into scheduled runs that show as failed the moment a hit is blocked, a page goes silent or a form changes.Practical guide
