Google Ads Integration

Every Phone Call, Traced Back to the Click

Stop guessing which Google Ads drive phone calls. CallFlux uses Dynamic Number Insertion to attribute every call to the exact keyword, ad, and campaign — then uploads the conversion back to Google Ads automatically.

The Problem

Your Google Ads generate calls.
But you can't prove it.

You spend $2,000/month on Google Ads. People click your ads, visit your website, and some of them pick up the phone. But in your Google Ads dashboard, those phone calls are invisible. You see clicks and impressions — not the 30 calls that turned into $15,000 of revenue.

Without call attribution, you can't tell which keywords convert, which ad copy works, or whether your budget is allocated correctly. You're optimizing in the dark.

Without Call Tracking

Google Ads shows 500 clicks this month
3 form submissions tracked as conversions
You think ROAS is 0.5x — campaign looks like a failure
You cut budget or pause the campaign

Reality: Those 500 clicks also generated 47 phone calls and $18,000 in revenue — but you never knew.

How It Works

From ad click to Google Ads conversion — automatically

Five steps, fully automated, no manual work required after initial setup.

1. Visitor clicks your Google Ad

Google attaches a unique click ID (gclid) to the URL — this is the key to attribution.

2. DNI swaps your phone number

A tiny script on your site detects the gclid and displays a unique tracking number from your pool.

3. Visitor calls the tracking number

The call forwards seamlessly to your real business line. The caller never knows the difference.

4. CallFlux matches call → click

We link the incoming call to the exact ad click, keyword, and campaign that brought the visitor.

5. Conversion uploaded to Google Ads

The phone call appears as a conversion in your Google Ads dashboard — automatically.

DNI Number Pools

Why you need a pool of tracking numbers

Multiple visitors can be on your site at the same time. Each one needs their own tracking number so every call maps to the right click. Numbers recycle automatically after sessions expire.

Example: 3 concurrent visitors

Visitor A "emergency locksmith"

Sees (817) 555-0042

Visitor B "car key replacement"

Sees (817) 555-0043

Visitor C "lock rekey near me"

Sees (817) 555-0044

If Visitor B calls (817) 555-0043, CallFlux knows the call came from the keyword "car key replacement" — not a guess, a match.

Recommended pool sizes

Each number handles one concurrent visitor session. Sessions expire after ~30 minutes of inactivity, and numbers recycle back into the pool.

Comparison

CallFlux vs Google's native call forwarding

Google offers built-in forwarding numbers for ads. Here's why most serious businesses switch to dedicated call tracking.

  • True ROAS: 3.2x — campaign is highly profitable

Frequently asked questions

Does the caller know they're calling a tracking number?

No. The experience is completely seamless. The tracking number forwards to your real business line instantly. The caller hears your normal greeting, voicemail, or IVR.

What happens if I run out of numbers in my pool?

If all numbers are in use, the visitor will see your default business number. The call still goes through — you just won't get attribution for that specific session. This is rare with properly sized pools.

Does this work with Google Ads Smart Bidding?

Yes. CallFlux uploads call conversions to Google Ads via the API. Smart Bidding algorithms use this data to optimize for campaigns, keywords, and audiences that generate phone calls — not just clicks.

Can I use the same pool for other channels besides Google Ads?

Yes. CallFlux DNI detects all traffic sources — organic search, Facebook, direct visits, email, referral links. You can use a single pool for full-site DNI or create separate pools per channel.

How much do tracking numbers cost?

Phone numbers are $1.15/month each via Twilio (billed by Twilio). There are no additional per-number fees from CallFlux. You buy numbers directly inside the app.

Do I need a developer to set this up?

No. You copy one script tag into your website header — that's it. If you can paste HTML, you can set up DNI. Most users are live in under 10 minutes.
