Does it Make Sense to Run Google Ads Without Conversion Tracking? What Do Conversions Do?

Does it make sense to run Google Ads without conversion tracking? Learn what conversions do and how to accurately measure your budget and performance.

Google Ads campaigns run without conversion tracking answer the question "how many people saw it?"; but they completely fail to answer "how many people became customers?". The fundamental power of Google Ads is its ability to direct ad budget towards actionable results. This is only possible when Google Ads conversion tracking is set up correctly. Otherwise, campaigns cannot distinguish between those who fill out a form, call, or make a purchase; the budget may flow into inefficient clicks.

Conversions measure what action the user coming from the ad performed on the site: form submission, phone call, WhatsApp click, purchase, or quote request. Thanks to this measurement, Google Ads conversion data clearly shows which keywords, ad copy, and targeting actually bring in business. Thus, optimization is done data-driven, not "by guess".

More importantly, smart bidding strategies (like Max Conversions, Target CPA, Target ROAS) cannot function properly without conversion data. Google needs to know which clicks are valuable to use the budget effectively. Without conversion setup, the system cannot learn; and because it cannot learn, the budget is not directed to the right audience and right keywords. Result: increased spending, uncertain performance.

Running ads without conversion tracking might create a "being live" feeling in the short term; but it doesn't provide measurement for sales, leads, and real performance. Google Ads conversions are the foundation for taking control of ad investments, reducing risk while growing the budget, and producing sustainable results. Therefore, conversion tracking is not an option; it is an absolute must for successful Google Ads management.

Does It Make Sense to Run Ads Without Conversion Tracking?

Short answer: No.
But let's discuss why, clearly and technically.

Ads run on Google Ads without conversion tracking only generate clicks and impressions. This data doesn't tell us if the ad is actually working. Because in Google Ads, the crucial question is:

"Are these clicks bringing me business, customers, or sales?"

Without conversion tracking, Google Ads cannot distinguish:

Users who fill out a form from those who bounce immediately
Customers who call from visitors who just browse the site
Audiences close to purchase from irrelevant traffic

Because it cannot make this distinction, the system may spend the budget on areas that get the most clicks but generate the fewest results. So, ads "seem" to be working; but they don't reflect in business outcomes.

Also, without conversion tracking:

It's unknown which keywords work
It's unmeasurable which ad copy brings customers
Optimization is intuitive, not data-driven

At this point, ad management ceases to be a professional marketing activity and turns into a trial-and-error process.

Running ads without conversion tracking is like speeding in a car without a speedometer. You might be going, but you won't know where you're going, how much fuel you're using, or if you're reaching your destination.

In the next section, if you like, let's move on to "What Do Conversions Do?" and explain with clear examples how conversions directly impact Google Ads optimization.

What Do Conversions Do?

Conversions are the only true criterion in Google Ads for deciding whether ads are "good or bad". Clicks, impressions, or increased traffic alone are not meaningful; the real value is whether this traffic translates into business results.

Thanks to conversions in Google Ads, the system learns this:

"Which user profile, which keyword, and which ad truly generate results?"

Without this learning, Google only sees interaction; with conversions, it starts to see intent.

When conversion tracking is active:

Ad budget is directed to users closer to sales or inquiries
Keywords that don't bring business automatically fall into the background
Ad copy that produces real performance comes to the forefront

So, conversions transform Google Ads from a "traffic machine" into a sales channel that brings customers.

Furthermore, conversions are essential not only for measurement but for optimization itself. Google's smart algorithms (such as Max Conversions, Target CPA, Target ROAS) base their decisions entirely on conversion data. The system understands which clicks are valuable through conversions.

Without conversions:

Smart bidding strategies don't work effectively
Budget goes to "cheapest clicks," not to the most valuable customers
Ad performance decreases over time instead of increasing

For this reason, conversions are not just a reporting tool. They are the fuel for Google Ads optimization. A properly established conversion structure means more customers, higher quality leads, and more measurable results with the same budget.

Which Actions Should Be Counted as Conversions?

In Google Ads, the concept of conversion is not limited to "sales" only. What is crucial is whether the user coming from the ad takes a step that serves your business goal. Therefore, the actions defined as conversions must be directly related to the business's sales process. Randomly chosen actions or those that only involve "engagement" inflate conversion data but do not contribute to optimization.

For a website, the most basic conversions are typically direct communication actions like form submissions, phone calls, and WhatsApp clicks. This is because these steps show that the user is genuinely intending to purchase or request a quote. Especially in the service industry, a "user who gets in touch" conversion is the strongest indicator of a potential sale. The Google Ads system, when it sees these actions, starts to allocate more budget to users who are likely to exhibit similar behavior.

For e-commerce, the definition of conversion is clearer. A purchase is the most valuable conversion and is central to ad optimization. However, merely tracking "purchase" conversions is not always sufficient. Intermediate actions like adding to cart or proceeding to checkout, when correctly structured, accelerate the system's learning process. The important thing here is that these actions are set up as supporting conversions that back the main goal, without overshadowing it.

One common mistake is defining actions like page views or time spent on site as conversions. While these metrics are valuable for analysis, when used as conversions in Google Ads optimization, they mislead the system. This is because Google starts to believe that users who "view a lot" but "don't bring business" are valuable. The result is increased budget with no corresponding increase in actual conversions.

When correct conversion actions are defined, Google Ads learns not only who clicks the ad but also who has the potential to become a customer. This learning enables campaigns to produce higher quality results at a lower cost over time. Therefore, conversion definition is one of the most strategic decisions in an ad account; it is not a technical detail but a factor that directly affects profitability.

Can Google Ads Optimization Be Done Without Conversions?

Theoretically, yes; but in practice, it's not sustainable. Google Ads optimization without conversion data relies heavily on assumptions. It's not clear which keywords work, which ads bring customers, or which audience is more valuable. In this scenario, optimization ceases to be a data-driven process and quickly gets stuck.

Google Ads' algorithm needs feedback to optimize campaigns. These feedbacks are conversions. As the system receives conversions, it learns which user profiles, devices, times, and search intents yield better results. Without conversions, Google only analyzes clicking behavior. Merely clicking often indicates curiosity, not intent.

This situation becomes especially clear as the budget grows. The difference might not be immediately noticeable with small budgets; however, as spending increases, costs rise in accounts without conversion data, performance fluctuates, and stability is lost. This is because the system doesn't know where to direct the budget. It goes to the users who click the most, not the users who bring the most conversions.

Moreover, manual optimization without conversion data is also limited. Ad copy can be changed, keywords can be added or removed; but the impact of these changes on real business results cannot be accurately measured. This makes it uncertain whether the ad manager is making the right decisions. The feeling of success is reduced to an increase in clicks in reports.

In accounts with conversion tracking, optimization reaches a completely different level. Google Ads begins to invest not only in past data but also in users who are likely to convert in the future. This allows campaigns to require less intervention over time, produce more predictable results, and achieve budget control.

Optimization in Google Ads is possible without conversions; however, it is inefficient, based on guesswork, and short-lived. True optimization begins with conversion data and is strengthened by the system's learning.

Why Do Ad Costs Increase When Conversions Are Not Set Up?

When conversions are not set up, Google Ads cannot direct the ad budget based on which clicks are valuable. The system only sees clicking behavior; it cannot know whether a click turns into a sale, an inquiry, or contact. In this case, the algorithm prioritizes the cheapest and most clicked searches. However, these searches are often made by users with low purchasing intent, driven by curiosity, or are irrelevant. As a result, while the number of clicks increases, real business results stagnate.

Another reason for increased costs in accounts without conversion data is incorrect learning. Since Google Ads doesn't receive conversion signals, it cannot learn which audiences, times, or devices are more effective. Without this learning, the budget is spread across a wide area, and waste becomes inevitable. Especially in highly competitive sectors, this leads to a rapid increase in cost per click. Ad spend increases; but sales, leads, or inquiries do not increase at the same rate.

In short, costs increase when conversions are not set up because the system is fed with incorrect signals. Google Ads rewards "the user who clicks," not "the user who brings results." This leads to an uncontrolled increase in ad budget.

How Does Correct Conversion Setup Affect Ad Performance?

A correctly configured conversion setup directly and permanently impacts Google Ads performance. When the system clearly understands which actions are valuable for the business, it starts to direct the budget towards user profiles who are more likely to take those actions. This means ads might receive fewer impressions but generate higher quality traffic. Performance improvement is usually seen not in the number of clicks, but in the number of conversions and the cost per conversion.

Correct conversion setup also accelerates the optimization process. As Google Ads learns which keywords bring actual customers, it de-prioritizes inefficient searches. Similarly, ad copy that generates conversions is shown more frequently. This learning process gradually produces more stable results and reduces performance fluctuations. The ad account moves from an "experimental" structure to a measurable and predictable channel.

Furthermore, a correct conversion structure ensures that smart bidding strategies work efficiently. Strategies like Target CPA or Maximum Conversions make their decisions entirely based on conversion data. The cleaner and more accurate this data, the stronger the ad performance. When clear and business-goal-aligned conversions are defined instead of incorrect or incomplete ones, it becomes possible to achieve more results with the same budget.

Most Common Conversion Setup Errors in Google Ads

Among the most common conversion errors in Google Ads is defining incorrect actions as conversions. When interactions like page views, time spent on site, or scrolls are marked as conversions, the system is misled. Google perceives these actions as valuable and starts directing the budget to users who do not bring business. This error is often made with the aim of "increasing the number of conversions"; however, in the long run, it significantly degrades performance.

Another common mistake is defining multiple conversions with the same value. For example, if form submission and thank you page views are treated as the same conversion, the system cannot distinguish the actual result. This inflates conversion data and complicates optimization. For Google Ads, it's not the quantity of conversions that matters, but the accuracy of the conversion signal.

Finally, technically incomplete conversion setup is also a frequent problem. Tags firing on the wrong page, triggering repeatedly, or not being measured on certain devices compromise the reliability of the data. In such cases, Google Ads learns; but it learns the wrong thing. This results in budget loss and decreased performance.

Correct conversion setup is not a technical detail; it is the foundation of Google Ads success. Even a small setup error can lead to the entire advertising strategy going in the wrong direction.
