How to See Google Ad Assumptions

Every Google Ads campaign is built on a stack of hidden assumptions. You assume a certain audience will convert, a specific keyword signals buying intent, or that one piece of ad copy is more compelling than another. This article will show you how to stop guessing and start using data to find and validate these assumptions, turning your campaigns from hopeful bets into predictable revenue drivers.

What Are "Google Ads Assumptions"?

When we talk about assumptions in Google Ads, we're not talking about a specific feature or setting. We’re talking about the untested hypotheses that form the foundation of your entire strategy. These are the "things we believe to be true" when we set campaigns live.

These hidden beliefs quietly influence every decision you make, from bidding strategies to ad creative. The problem is, an incorrect assumption can silently drain your budget for weeks or months. The goal is to make these assumptions visible so you can challenge, test, and validate them with real data.

Common examples include:

• Your Audience Assumption: "I assume my ideal customer is a 35-44-year-old male interested in finance."
• Your Keyword Intent Assumption: "I assume everyone searching for 'emergency plumbing services' is in a hurry to buy."
• Your Ad Copy Assumption: "I assume '50% Off' will generate a higher click-through rate than 'Free Shipping'."
• Your Landing Page Assumption: "I assume my main product page is the best destination for all ad traffic."
• Your Device Assumption: "I assume most people research on mobile but make the final purchase on a desktop."

Leaving these assumptions unchecked is like navigating without a map. Let's look at how to use your existing Google Ads data to find the truth.

Finding Your Assumptions: A Guided Walkthrough

You can find the clues you need right inside your Google Ads account. By looking at specific reports, you can compare your initial beliefs with what your performance data is actually telling you.

Uncovering Your Audience Assumptions

One of the first assumptions we make is about who we're trying to reach. You likely built your campaigns with a target demographic in mind. But is that who is actually converting?

How to Check:

1. Navigate to a specific campaign or ad group.
2. In the left-hand menu, look under the "Audiences" tab and select "Demographics."
3. Here, you'll see tabs for Age, Gender, Household Income, and Parental Status.

What to Look For:

Don't just look at clicks or impressions. Focus on the metrics that matter to your business, such as Conversions, Cost per Conversion (CPA), and Conversion Rate.

You might have assumed the 25-34 age bracket was your sweet spot, but the data might reveal that the 45-54 bracket has a much higher conversion rate and a lower CPA. This is a classic example of data invalidating an assumption. Similarly, you might find that while men click more, women convert at a higher rate.

Action Step: Based on this data, you can make informed bid adjustments. Increase bids for high-performing demographics and decrease them — or even exclude — the underperformers that are driving up your costs.

Testing Your Keyword Intent Assumptions

You bid on keywords based on the assumption that they represent a certain level of intent. But the specific search queries people type can tell a very different story. The Search Terms report is your source of truth here.

How to Check:

1. Navigate to a Search campaign or ad group.
2. In the left-hand menu, click on "Keywords" and then select the "Search Terms" report.

What to Look For:

This report shows you the exact queries that triggered your ads, not just the keywords you bid on. Read through this list carefully. Are the searches aligned with the commercial intent you assumed?

• Broad Match Mishaps: If you're bidding on "crm software" with broad match, you might find your ads showing for "free crm software for nonprofits" or "how to build a crm," which have very different intentions.
• Informational vs. Transactional: A person searching for "best running shoes" might be in research mode, while someone searching for "buy Brooks Ghost 15 size 11" is ready to purchase. You might be incorrectly assuming both have the same level of urgency.

Action Step: The Search Terms report is a goldmine for your negative keyword list. Add any irrelevant or low-intent queries as negatives to stop wasting money. This process helps you refine your targeting to users who have a genuine intent to convert.

Validating Your Ad Creative Assumptions

Every advertiser has a gut feeling about what messaging will work best. But "gut feeling" is just another word for an assumption. A/B testing your ads is the only way to know for sure.

How to Check:

1. Navigate to an ad group where you have at least 2-3 active ad variations. If you don't, create some now!
2. In the left-hand menu, click on "Ads & assets" and then "Ads."

What to Look For:

Filter the results by metrics like CTR, Conversion Rate, and CPA. Did the headline you assumed was a winner actually perform the worst? Sometimes, a very direct and simple call-to-action (e.g., "Shop Now") defeats a more creative but less clear one.

Pay close attention to Responsive Search Ads. Google is automatically testing combinations for you. Expand an ad to see the "Asset details" and discover which headlines and descriptions are getting the most impressions and being marked as "Best" performers. Google is helping you validate your copy assumptions at scale.

Action Step: Routinely pause your lowest-performing ads. Create new variations based on elements from your winners. This iterative process of testing, learning, and refining is the core of successful ad management.

Checking Your Landing Page and Device Assumptions

Where you send your traffic — and what device people are on — are two final, massive assumptions that can make or break your performance.

How to Check:

• For landing pages, find the "Landing Pages" report in the main left navigation.
• For devices, find the "Devices" link, usually under "Audiences" or its own top-level menu item.

What to Look For:

For landing pages, scan the Conv. Rate column. If a page has a significantly lower conversion rate despite getting expensive traffic, your assumption that it's a good destination is probably wrong. The page might have a poor user experience, load slowly, or have a messaging mismatch with the ad.

On the Devices report, check the performance breakdown between Computer, Mobile, and Tablet. Many businesses assume mobile serves for awareness while desktops drive sales, only to find their data shows the opposite. A high mobile CPA, for instance, could indicate a poorly optimized mobile landing page.

Action Step: Optimize or pause campaigns pointing to underperforming landing pages. Use the device performance data to implement mobile or desktop-specific bid adjustments to allocate your budget more efficiently.

Beyond Google Ads: Connecting the Dots to Business Reality

Challenging your assumptions within Google Ads is a great start, but it only shows you part of the picture. Google’s conversion tracking can tell you if a user submitted a form or completed a purchase, but it can’t tell you what happened next.

To truly validate your biggest business assumptions, you need to connect your ad performance to real outcomes. This requires answering deeper questions:

• Does the "low CPA" campaign also produce the lowest customer lifetime value (LTV)? (Requires connecting Google Ads to Shopify or Stripe)
• Do the leads generated from a specific keyword campaign close at a higher rate in our CRM? (Requires connecting Google Ads to Salesforce or HubSpot)
• Which ad groups drive the most engaged website visitors, not just clicks? (Requires connecting Google Ads data with Google Analytics behavior metrics)

Answering these questions has traditionally been a painful process. It often involves exporting multiple CSV files from different platforms and wrestling with them in a spreadsheet for hours, trying to stitch everything together before the data is already out of date.

Final Thoughts

By moving beyond default campaign setups and actively looking for your hidden assumptions, you shift from simply managing ads to making strategic, data-driven decisions. The reports inside Google Ads provide the perfect starting point to challenge what you think you know about your audiences, keywords, and creative.

To answer those deeper business questions, you need to see the whole picture. Instead of manually pulling data from Google Ads, Google Analytics, Shopify, and Salesforce every week, we built Graphed to automate the whole process. By connecting all your tools in one place, we let you use simple, natural language — like "show me a dashboard of my Facebook Ads spend vs Shopify revenue by campaign" — to get real-time dashboards and instant answers, turning hours of analysis into a 30-second conversation.
