What it does

The TrueMetriks Ad Overlay puts your real numbers right next to Facebook's and Google's, on the screen you already work in. It adds a dark TrueMetriks toolbar above your ad table and eight extra cells to every ad, ad set, ad group, or campaign row.

Spend is read from the ad platform; every other number comes from TrueMetriks. Each one is calculated for the date range and attribution model you pick in the toolbar, so the ROAS you see is real, not a platform estimate.

Install it

The extension is published on the Chrome Web Store as "TrueMetriks Ad Overlay".

1. Open the Chrome Web Store listing and click Add to Chrome, then approve the permissions.
2. Pin the extension so the icon stays in your toolbar.
3. Click the icon and choose Connect to TrueMetriks. It signs you in with your existing app.truemetriks.com login, so there is no separate password. Once connected the popup shows Connected as [email protected].

After that, open the Ads tab to see your numbers. The two platforms differ slightly:

Blank overlay? You are almost always on the wrong tab. Switch to Ads and refresh.

The eight cells

The overlay always adds the same eight cells, in this fixed order, regardless of the order you turn them on.

ROAS and Profit are colour-coded so good and bad rows jump out: green when a row is winning, red when ROAS drops below break-even or Profit goes negative.

The toolbar controls

Everything is driven from the dark TrueMetriks bar at the top of the page.

Attribution

Switch how credit is assigned between First touch, Last touch, and Any touch. Every cell instantly recalculates for the model you pick.

• First touch credits the ad that first introduced the customer.
• Last touch credits the ad they clicked right before buying.
• Any touch credits every ad that was part of the journey.

This is the same attribution choice you have on the TrueMetriks dashboard. See Buyer journeys and attribution for how the three models differ.

Audience

Filter the numbers by who converted: everyone, only first-time buyers, or only repeat buyers.

Set it to New only to optimise your prospecting campaigns on fresh customers instead of repeat purchases that would have happened anyway. See New vs returning customers for the full picture.

Columns

Turn any of the eight cells on or off. The count in the toolbar (Columns: 8) shows how many are visible.

Date

The overlay reads the date range from the ad platform's own date picker (shown as Date: maximum), so change the date in Facebook or Google as usual and the cells follow. Nothing to set here.

Refresh and the status dot

Refresh pulls the latest numbers (the overlay also caches for a minute so it stays fast). The dot on the right shows the connection: green for connected, amber while syncing, red if something is wrong.

Hide cells

Hide cells collapses the eight TrueMetriks cells so the ad platform's own right-edge columns show again. Click Show cells to bring them back - nothing is lost.

Google Ads: enable the ID columns first (required)

Facebook works the moment you open it. Google does not: the overlay matches each Google row by Google's own ID column, which Google hides by default, so until you turn it on there is nothing to match and no numbers show.

This step is required. Enable the ID column on all three views - Campaigns, Ad groups, and Ads. Each has its own ID, and skipping one leaves the overlay blank on that view.

You do this once per view, and Google remembers it. The three views sit in the Google Ads left menu:

Step 1 - open Modify columns

On the view you are setting up, find the toolbar above the ad table and click Columns, then Modify columns.

Step 2 - search the ID and add it

In the Modify columns panel, type the ID for the view you are on into the search box, tick it so it moves into Your columns on the right, then click Apply at the bottom.

Step 3 - repeat on all three views

Each view needs its own ID. Do the same on the other two tabs:

Once a view has its ID column on, refresh the page and the overlay's eight cells appear on every row. If you ever see Google rows with no TrueMetriks numbers, the overlay tells you which column is missing with a message like "Enable the Campaign ID column to see TrueMetriks data" - go back to Modify columns for that view and switch it on.

Why these numbers beat the platform's own

The whole reason the overlay exists is that the numbers Facebook and Google show you are usually too low and credited to the wrong ad.

• More sales counted. iOS, ad blockers, and cookie limits drop a big share of pixel events; TrueMetriks catches them server-side.
• A longer window. TrueMetriks keeps the full journey, so a sale weeks after the click still gets credited to the ad that drove it, instead of expiring on the platform's short window.
• Your choice of attribution. First, last, or any touch, recalculated live, instead of the one model the platform picks for you.
• One scoreboard. Facebook and Google each only see their own conversions and over-claim; the overlay scores every row the same way, so their ROAS is finally comparable.

The result is a per-ad ROAS and Profit you can actually trust enough to scale or cut on.

Plan availability

The Chrome extension is available on the Growth and Unlimited plans. On Starter it installs but the popup shows an upgrade prompt instead of the overlay. Upgrade from app.truemetriks.com and it turns on right away.

Good to know

• It is read-only. The overlay only reads your ad screens and pulls the matching TrueMetriks numbers through your own login. It never edits, pauses, or spends anything in your ad accounts.
• It works in Facebook Ads Manager (facebook.com/adsmanager and business.facebook.com) and Google Ads (ads.google.com).
• It follows your ad platform's light or dark theme automatically.
