A Google Ads conversion-tracking checkup for small businesses

Why check your conversion tracking at all?

Google Ads uses the conversions you track for two jobs. It reports them to you, and it uses them to decide who to show ads to and how much to bid. If tracking is wrong, both jobs go wrong. You see a cost per conversion that is not real, and the bidding system chases the wrong thing.

Tracking also drifts. A new website theme, a changed thank-you page or a second plugin can quietly break or double a tag. A checkup every few months, and after any site change, catches this early. You do not need to read code to do most of it. You need your Google Ads account, your own sales or lead records and an hour.

Step 1: Is the right action set as primary?

In Google Ads, open Goals, then Conversions. Every action there is either primary or secondary. Google explains that primary actions are the ones reported in the Conversions column and used for bidding, while secondary actions are for observation only and show up under All conversions.

Look down the primary list. Each item should be something that makes you money or directly leads to it: a purchase, a submitted quote form, a booked call. Page views, button clicks, video plays and add-to-cart events are useful signals, but if they sit in primary they inflate your numbers and teach the bidding system to buy cheap clicks instead of customers. Move them to secondary.

Step 2: Is each action counted the right way?

Each conversion action has a counting setting. Google's help page says that with "every" counting, Google Ads counts every conversion after an ad interaction, which suits sales because each sale adds value. With "one" counting, it counts only one conversion per ad click, which suits leads because a second form from the same person is rarely a second customer.

A lead action set to "every" is a common reason a lead business sees more conversions than inquiries. Fix the setting and your reported cost per lead becomes more honest. Our cost per lead guide covers what to do with that number next.

Step 3: Compare Google's total with your own records

Pick last month. Write down conversions from your primary purchase or lead action. Then count real orders from your payment processor or store, or real leads from your inbox or CRM, for the same dates. Expect some gap, because Google only counts people it can link to an ad and gives credit by click date. But the gap should be explainable. The chart shows how common mistakes bend the reported cost per purchase on the same $3,000 of spend.

Warning signs to look for:

• Google reports more purchases than you had in total. A tag is probably firing twice, often once from a plugin and once from Google Tag Manager.
• Conversions arrive on days with no orders. A tag may sit on a page people revisit, such as an account page, instead of a one-time confirmation page.
• Far fewer conversions than expected. A tag may be missing from one checkout path, such as a payment page hosted elsewhere.
• Conversion value is the same for every sale. The tag is probably sending a fixed number instead of the real order total.

Step 4: Enhanced conversions and consent

Enhanced conversions add a scrambled version of details a customer already typed, such as an email address, to your conversion tag. Google says the data is hashed with SHA256 (turned into a code that cannot be reversed) before it is sent, and it helps match conversions that cookies miss. Google reports that the retailer ASOS recorded a sales uplift of 8.6% in Search and 31% in YouTube after turning it on. That is one large advertiser, so treat it as an example, not a forecast.

If you use a cookie banner, consent mode passes each visitor's choice to Google's tags. Google can model conversions from people who decline, but its eligibility rules call for 700 ad clicks over a 7 day period per country and domain grouping. Many small accounts fall below that, so expect fewer reported conversions rather than modeled ones.

Keep the checkup going

Write down what you found and what you changed, with dates, so you can tell later whether a jump in conversions was real or a tracking fix. Then repeat the comparison in Step 3 each month. You can do that in a spreadsheet, or with Matrix ROI, built by Smith App Studio, which places Google's claimed conversions beside the sales your own records confirm, day by day.
