Google Ads Conversion Tracking: Set Up Enhanced Conversions

If your Google Ads account reports 80 conversions but your sales team logged 20 real enquiries, the numbers are not just untidy. Smart Bidding learns from them, so Google Ads conversion tracking that counts the wrong things teaches the system to find more of the wrong people.

This guide shows which actions to track, how to count them, how enhanced conversions work and how to verify the result. It is written for Indian businesses running Search campaigns for leads or online sales, who want clean data before they scale spend.

What is Google Ads conversion tracking and why does it matter?

Google Ads conversion tracking is a measurement setup that records valuable actions after an ad interaction and reports them back to your account. Those actions can be a form submission, a call, a WhatsApp click or a purchase.

The "Conversions" column reflects your primary conversion actions, and Google says this column is generally used for bidding optimization. That is the key point: whatever you mark as primary is what automated bidding tries to increase. If page views or button hovers are primary, you will buy more of those.

Tracking quality also shapes the rest of the account. Good data makes negative keyword reviews and Performance Max decisions far more reliable.

Which conversion actions should you track?

Track the action closest to revenue as primary, and keep supporting actions as secondary so they do not distort bidding. The right set depends on whether you sell online or generate leads.

Secondary actions still show up in the "All conversions" column, so you keep visibility without feeding them into bidding. Google recommends setting only bottom-of-funnel actions as primary to avoid inflating counts.

A practical rule: if your sales team would not celebrate it, do not make it primary. For service businesses, a raw form fill is often too soft, and a call longer than a set number of seconds or a CRM-qualified lead is closer to the truth.

How should you count conversions: One or Every?

Use One for lead actions and Every for purchases. Google explains that Every counts each conversion after an interaction, while One counts only a single conversion per ad click, which suits leads because only one unique lead per click likely adds value.

Defaults matter here. Google Ads uses Every as the default for website actions and imported actions, so a lead form that people submit twice, or a thank-you page that gets refreshed, can double count unless you change the setting. Changes apply to future conversions only, not past data.

For ecommerce, pass a unique order ID as the transaction ID so a page reload does not record the same sale twice. If you run a Shopify store, our guide to Shopify payment gateway setup in India explains why COD and prepaid orders need consistent order events.

What are enhanced conversions and when should you use them?

Enhanced conversions send hashed first-party customer data, such as an email address, to Google so your conversion measurement is more accurate. Google's help page says the hashed data is matched with signed-in Google accounts to attribute conversions to ad events. There are two versions:

Either version needs first-party data to be available. For leads, Google requires at least a phone number or an email, and prefers email because it is unique and less likely to be reformatted in your CRM. It also needs auto-tagging turned on, because auto-tagging is necessary to import offline conversions.

Enhanced conversions do not replace your normal conversion tag. They add a signal to it, so set up the base tracking first.

How is customer data hashed and prepared?

The Google tag or Google Tag Manager hashes personal data in the browser using SHA-256 before it reaches Google, and anything you upload yourself must be normalized and hashed the same way. Google's developer documentation lists the rules:

• Convert text to lowercase and remove leading and trailing spaces.
• For gmail.com and googlemail.com addresses, remove periods before the domain.
• Format phone numbers to the E.164 standard, which means a plus sign, country code and number, such as +919812345678 for an Indian mobile.
• Hash email, phone, first name, last name and street address; do not hash country, state, city or zip code.

Indian numbers are a common failure point. A form that stores "98123 45678" without the +91 country code will not match, so add the country code in the tag variable or collect it in the form. Also make sure your privacy policy and consent banner describe this data use, and check Google's customer data policies before switching the feature on.

How do you set up Google Ads conversion tracking step by step?

Set up the base conversion tag first, then enhanced conversions, then test. This sequence works for most Tag Manager setups.

1. Create the conversion action. In Google Ads, open Goals, then Conversions, and create a website action for your form submit, call or purchase. Give each real outcome its own action.
2. Set the goal and count. Choose the category, mark primary or secondary, set One for leads or Every for sales, and enter a value if you can estimate one.
3. Install the tag. Use the Google tag with Google Tag Manager and fire the conversion on the real success event, such as a form-submitted event or the order confirmation, not on any button click.
4. Pass value and transaction ID. For stores, send order value, currency and a unique order ID through the data layer.
5. Turn on enhanced conversions. Accept the customer data terms, then map the email or phone variable to the tag's user-provided data fields.
6. Enable auto-tagging. This is required for offline imports, and your landing pages must keep the click ID parameter in the URL or the session.
7. Test with a real submission. Use Tag Manager preview and Tag Assistant, submit a form, and confirm the conversion event fires once.
8. Check the status. Wait for the conversion action status to update and then compare against your CRM.

If your lead form lives on a thin page that loses parameters after a redirect, fix that first. Our guide to PPC landing page best practices covers keeping the click path intact.

How do you track offline leads and calls?

Capture the lead's email or phone at form submit, store the Google click ID with the lead in your CRM, and import the outcome later. For enhanced conversions for leads, Google's checklist says to create a unique conversion action for each offline event you care about, such as "Qualified Lead" or "Converted Lead", with the source set to import from clicks.

Google also recommends marking the new action as secondary for the first two to three weeks, uploading conversions daily, and including the click ID whenever it is available. Because the system needs all conversions for the event, do not upload only the ones you believe came from Google Ads.

For calls, decide whether a call from an ad, a call to a number on your site and a WhatsApp click are one outcome or three. Google's defaults count calls from ads and calls to a website number once, which is usually right. Keep click-to-chat as secondary until you know how many chats become sales.

What tracking mistakes cost the most?

Most losses come from counting too much, not too little. These are the patterns we see most often when reviewing accounts.

Changing goals constantly is also costly. Google notes that frequent adjustments to budgets, targets or conversion goals reset the standard 7 to 14 day learning period, so change one thing, then wait. Expect small differences between Google Ads and Google Analytics, because they use different attribution, and see our GA4 attribution setup guide for how to read both.

How Arham Technology approaches Google Ads conversion tracking

Arham Technology treats tracking as the first deliverable of a PPC engagement, not an afterthought. Our PPC and Google Ads management service follows this process:

1. Account forensics. We audit existing conversion actions, duplicate tags and primary or secondary settings.
2. Tracking truth. We set up conversions through Google Tag Manager and GA4, verify them with real test submissions and remove duplicates and distorting micro-conversions.
3. Enhanced conversions. We configure enhanced conversions for web or leads, depending on whether your sales close online or offline.
4. Lead-quality feedback loop. Where possible we connect CRM outcomes back to Google Ads, so bidding learns from qualified leads rather than form fills.
5. Landing page alignment. If a page is breaking click IDs or hiding forms, we brief or build a fix through our landing page development service.

Tracking audits can be a standalone engagement before or alongside full management. We do not promise specific CPAs or returns, and the cost of media depends on your category, as shown in our Google Ads cost guide for India.

What should you do next?

Open Goals, then Conversions, and list every action in the account with its primary or secondary setting and count method. Remove or demote anything your sales team would not call a result, then run a test submission and compare it with your CRM.
