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

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.
