A report can show hundreds of conversions and still fail to answer whether advertising is actually delivering business results. The reason is simple: not every user action has the same value.

A person views the pricing page — that is a useful signal. They click a phone number — that is a stronger signal. They submit an inquiry — now we are closer to the outcome. A manager confirms that the inquiry is relevant — the value increases further. And when the deal is paid, we have an action directly connected to revenue.

In web analytics, all of these events can be called conversions. But for an advertising algorithm, the difference between them matters a great deal.

If you tell the system that the main goal is a button click, it will look for people who are likely to click. If you use a qualified lead or a sale as the primary signal, the task becomes completely different.

That is why the right question is not only what a conversion is, but also which of your conversions is already close enough to the business outcome to be used as the basis for advertising optimization.

What Is a Conversion?

A conversion is a user action that a business considers valuable for achieving its goal. It does not have to be a purchase.

For an ecommerce store, it may be a completed order. For a clinic, it may be an appointment booking. For a B2B company, it may be a demo request or a high-quality inquiry. For SaaS, it may be a trial, a paid subscription, or another action depending on the sales model.

A business can also track smaller events: opening a form, adding a product to the cart, viewing the pricing page, opening a messenger, or clicking a phone number.

That is why the statement “the website generated 300 conversions” says almost nothing without context. First, you need to understand which events were counted and how close they are to the outcome the business is spending advertising budget to achieve.

What Is a Website Conversion?

A website conversion is a target action a user completes while interacting with a website. It may be a purchase, form submission, appointment booking, registration, phone call, or another important action.

One website may have many such events. But that does not mean they all have the same weight or should influence advertising optimization in the same way.

What Is a Conversion in Sales?

In sales, a conversion usually refers to moving a potential customer to the next meaningful stage of the funnel.

For example:

lead → qualified lead → proposal → deal → sale.

Advertising may only see the submitted form. A day later, the sales team may already know that some of those inquiries were irrelevant. If these data are not connected, the advertising platform and the business are effectively measuring success in different ways.

That is why the number of website conversions is not the same as the number of results that are actually valuable to the business.

How to Calculate Conversion Rate

Conversion Rate shows what proportion of users or sessions completed the required action.

The formula is simple:

Conversion Rate = number of conversions / number of users or sessions × 100%

For example, if a website receives 1,000 visitors and 40 inquiries:

40 / 1,000 × 100% = 4%.

The Conversion Rate is therefore 4%.

Now add another layer. Of those 40 inquiries, 25 turned out to be irrelevant, 10 were qualified, and three resulted in sales.

Formally, the form CR is still 4%. For the business, however, these additional data completely change the picture.

That is why maximizing Conversion Rate should not be a goal in itself. It is important to understand not only how many users completed an action, but also what happened after that action.

Macro- and Micro-Conversions: What Is the Difference?

Dividing conversions into macro- and micro-conversions helps separate the final business outcome from intermediate behavioral signals.

What Is a Macro-Conversion?

A macro-conversion is an action directly connected to the main business goal or located very close to it.

It may be a purchase, a paid order, a confirmed appointment, a signed contract, or a qualified lead.

What matters is not the name of the event, but its role.

If a business earns money by selling products, a purchase is an obvious macro-conversion. If a company sells complex B2B services and there is no online purchase, a qualified lead or a confirmed demo booking may serve as the macro-conversion for the advertising system.

What Is a Micro-Conversion?

A micro-conversion is an intermediate action that shows the user moving toward a more important outcome but is not yet the outcome itself.

For example:

• viewing the pricing page;

• starting to fill out a form;

• adding a product to the cart;

• clicking a phone number;

• opening a messenger;

• watching a video;

• downloading a document.

These events are useful because they help identify points where users drop off.

If many people open the form but almost nobody submits it, we can see that the problem lies within that stage. If users actively add products to the cart but do not complete payment, we look for the problem closer to checkout.

Micro-conversions help explain behavior. But they should not automatically be treated as equivalent to the final business outcome.

The Same Action Can Be a Macro- or Micro-Conversion

The distinction depends not on the type of event, but on the business model.

A submitted form on a B2B website may be the main online conversion because the sales process begins there. The same form in ecommerce may simply be a product inquiry and have much less value than a purchase.

A phone click may be a secondary signal for one business. For another, where most sales are closed over the phone, phone contact is much closer to the main conversion.

Even a SaaS trial does not always have the same value. In a freemium model, there may be many registrations but only a small share convert to paid plans. In another product, a high-quality trial may predict a subscription so well that it becomes a useful advertising signal.

That is why there is no universal table where one action is always “macro” and another is always “micro.”

Which Conversions Can Be Considered Macro-Conversions?

A good macro-conversion should be sufficiently close to the real business result.

To identify one, check several things:

• whether the event has a direct or strong connection with revenue;

• whether there is a high probability that the user will become a customer afterward;

• whether the business genuinely values this action;

• whether it can be tracked correctly;

• whether there are enough such events for the advertising system to learn from.

The final criterion is especially important. The most valuable conversion is not always the best signal for the algorithm if it happens too rarely.

Examples of Macro-Conversions for Different Businesses

For ecommerce, the primary macro-conversion is usually a purchase or completed order. Adding a product to the cart or starting checkout is useful for analytics but occurs earlier in the funnel.

For a service business, the main conversion may be a qualified inquiry or confirmed consultation.

In B2B, it may be a qualified lead, SQL, or demo booking, depending on which stage already predicts a future deal well enough.

For a medical center, deeper conversions may include a confirmed appointment, a qualified phone call, or an actual visit.

In SaaS, it is usually a paid subscription and sometimes a high-quality trial or demo request.

In all these cases, what matters is not the format of the event but how close it is to revenue and real business value.

Which Actions Should Not Automatically Be Treated as Primary Conversions?

The problem is usually not that the business tracks too many events. It appears when every event becomes an equally important advertising goal.

A click on a phone number does not mean a call actually happened. The person may have clicked accidentally, changed their mind, or failed to reach anyone.

Opening a form does not mean an inquiry was submitted. It is only the beginning of an action.

Opening a messenger does not guarantee a message. The user may open the app and never write anything.

Even further from the final action are contact page views, scrolls, time on site, or video views.

These events are not useless. On the contrary, they show the customer journey well and help identify where problems occur.

But the usefulness of an event for analytics and its suitability as the main signal for advertising are two different things.

Why Optimizing Advertising for Micro-Conversions Can Be Risky

The advertising algorithm does not know your real intentions. It only sees the signal you provide.

If the primary conversion is a phone-number click, the system learns to find people who are likely to click the button.

If the main goal is opening a form, it will look for users who tend to open forms.

If the conversion is a purchase, the task is much closer to the actual business goal.

This can create a paradoxical situation: everything inside the advertising account starts looking better. There are more conversions, CPA is lower, and the algorithm appears to have learned very well. But the number of real customers barely changes.

The system may indeed be well optimized.

Just not for the right outcome.

Primary and Secondary Conversions in Google Ads

The difference between main and supporting conversions is easy to see in Google Ads.

Primary conversions are the main conversions used as key signals for the relevant advertising goals and optimization.

Secondary conversions are supporting events that are useful to track and analyze but do not necessarily need to sit at the center of automated optimization.

For example, a clinic may track the entire journey:

doctor page view → phone click → form open → form submission → confirmed appointment.

All of these events provide useful information.

But if every one of them is made a Primary conversion, the advertising algorithm receives a mixed signal. This level of detail is useful for analytics. For bidding, a clear hierarchy is needed.

Which Conversions Should Advertising Be Optimized For?

A practical rule is:

optimize advertising for the deepest business conversion for which the system still receives enough high-quality data.

The second part of this rule is just as important as the first.

A sale is almost always closer to the business outcome than an inquiry. But if there are only two sales per month, the advertising system may not receive enough signals to work consistently.

Compare two cases.

500 inquiries → 70 sales.

Sales happen frequently enough and can already serve as a strong signal.

20 inquiries → 2 sales.

The final goal is the same, but there are far fewer data points. In this situation, it may temporarily be more useful to move one stage higher in the funnel — for example, to a qualified lead.

But that is not a reason to move all the way up to simple actions such as clicks or scrolls just because they happen more often.

You need to balance signal quality with signal volume.

Why You Should Not Always Optimize Directly for Sales

A final purchase or closed deal may look like the ideal goal. In theory, it is. In practice, everything depends on data volume and the length of the sales cycle.

In B2B, weeks may pass between an ad click and a deal. High-ticket services may generate only a small number of sales. For some local businesses, the final result happens offline.

If the advertising system sees only a few such conversions, the signal may be too sparse.

In that case, it makes sense to identify an earlier stage that happens more often but still predicts the final outcome well. This is why a qualified lead is often much more useful than a simple form submission.

The difference is fundamental: a form submission only tells you that someone completed a form. A qualified lead already indicates that the person at least roughly matches the profile of a potential customer.

Conversions and CRM: How to Bring Advertising Closer to Real Sales

The longer the funnel, the less accurately one online conversion reflects its final result.

Without CRM data, the advertising system may see only:

form submit.

The business actually sees:

form submit → qualified lead → opportunity → sale.

The evaluation of different advertising campaigns often changes after the first online action.

One campaign generates 100 inexpensive inquiries, of which only two result in sales. Another generates 40 more expensive inquiries, but 12 of them result in deals.

If Google Ads knows only about form submissions, the first campaign looks stronger.

If data about lead quality and sales are sent back into the system, it receives a completely different model of success.

That is why CRM feedback is not just another report for the marketer. It allows advertising optimization to move closer to the real business outcome.

How to Evaluate Conversion Quality

The number of conversions is only the beginning. It is useful to evaluate the full chain:

CR → CPL → qualified lead rate → CAC → revenue.

CR shows what proportion of traffic completes the required action.

CPL shows how much an inquiry costs.

Qualified lead rate shows what proportion of inquiries are actually high quality.

CAC shows how much a real customer ultimately costs.

Revenue connects advertising spend with income.

This is where it becomes clear why the statement “we increased conversions by 30%” does not yet describe success.

If the increase came from weak inquiries that do not convert into sales, the report may look better while the business result remains unchanged.

The Right Conversion Hierarchy Matters More Than the Number of Conversions

A website can track many useful events:

important page view → form open → form submission → qualified lead → sale → repeat purchase.

Each level answers a different question.

Early micro-conversions help diagnose behavior. A lead shows interest. A qualified lead adds information about quality. A sale is directly connected to revenue.

The problem is not that the business can see the entire funnel. On the contrary, that is good analytics.

The problem appears when every stage is passed to the advertising system as an equally desirable goal.

For measurement, you need detail. For optimization, you need priorities.

Common Mistakes in Conversion Setup

One of the most common mistakes is making every event a Primary conversion. Then a sale, inquiry, form open, and phone click effectively become equal signals.

Another mistake is treating a phone click as a real call or a form start as an inquiry.

Duplicate tracking is another common problem. The same action may be sent through GA4 and a separate Google Ads tag, while the team fails to notice that one result is being counted twice.

Different actions with different levels of quality may also be assigned the same conversion value. Ten random inquiries and ten qualified leads look identical to the algorithm if we do not pass the difference ourselves.

Without CRM feedback, the situation becomes even more difficult: the advertising system simply does not know what happened after the user clicked “Submit.”

In all of these cases, the problem is not necessarily Google Ads. The algorithm is simply receiving an inaccurate model of what the business defines as success.

How to Build a Conversion System for Advertising

The process should begin not with GTM or advertising account settings, but with the final business outcome.

What do we actually need: a purchase, visit, contract, subscription, or paid service?

Then the customer journey is mapped backwards into its main stages.

For B2B, it may look like this:

service page view → form open → inquiry → qualified lead → opportunity → sale.

After that, you can determine which events are needed for behavioral analytics and which event is the deepest sufficiently frequent signal for advertising optimization.

If there are many sales and the information about them returns quickly to the system, you can work closer to revenue. If sales are rare, use the previous high-quality stage.

Scrolls, form opens, contact clicks, and other micro-conversions do not disappear. They remain in analytics and help identify where people leave the process.

This allows the system to retain detail while giving advertising a clear goal.

More Conversions in a Report Do Not Always Mean Better Advertising

This becomes especially noticeable after changes to the conversion setup.

Suppose Google Ads previously counted only submitted inquiries. Then the team adds form opens, phone clicks, and messenger opens as Primary conversions.

The number of conversions immediately increases. CPA will most likely fall. The report looks better.

But the business has not suddenly started receiving more inquiries simply because the counting method changed.

Moreover, if Smart Bidding starts optimizing toward this new set of easier actions, the traffic structure may also change over time.

That is why after any conversion setup change, you should look not only at Google Ads metrics but also at what happened to qualified leads, sales, and revenue.

Macro- and Micro-Conversions Serve Different Purposes

You do not have to choose one or the other.

Micro-conversions show what happens between the first website visit and the final outcome. Without them, it is harder to understand why users do not convert.

Macro-conversions are needed to evaluate the real value of traffic and send a stronger signal to the advertising system.

If you only track sales, you may miss the point where large numbers of users drop out of the process. If you only track clicks, views, and form starts, you gain detailed behavioral analytics but lose the connection with revenue.

A strong measurement system does not try to reduce the entire funnel to one event. It simply understands clearly what each event is used for.

You Can Track Many Conversions. Optimization Should Be Selective

This is the main difference between measurement and advertising optimization.

In analytics, it is useful to see the entire user journey: views of key pages, CTA interactions, form starts, add-to-cart actions, and other micro-conversions.

But the advertising algorithm does not need to be told that all these actions have the same business value.

The purpose of advertising optimization is not to collect as many events as possible, but to find users who are most likely to generate the business outcome you actually need.

That is why a strong conversion architecture usually has several levels:

micro-conversion → lead → qualified lead → sale → repeat purchase.

You can track the entire chain. The primary goal should be the deepest level for which the system already has enough reliable data.

That is when conversion tracking stops being just a collection of events in a report and starts helping the advertising budget work toward real business results.

FAQ

What Is a Conversion in Simple Terms?

A conversion is a user action that is valuable to the business: a purchase, inquiry, appointment, registration, phone call, or another defined outcome. Different conversions can have different business value.

What Is a Website Conversion?

A website conversion is a target action completed by a user while interacting with a website. It may be a purchase, form submission, appointment booking, registration, or another event depending on the business model.

How Do You Calculate Conversion Rate?

Divide the number of conversions by the number of users or sessions and multiply by 100%. For example, 40 inquiries from 1,000 visitors result in a Conversion Rate of 4%.

What Is a Macro-Conversion?

A macro-conversion is an action closely connected to the main business goal: a purchase, qualified lead, confirmed appointment, contract, or another result with direct business value.

What Is a Micro-Conversion?

A micro-conversion is an intermediate action on the way to the main result, such as starting a form, adding a product to the cart, clicking a phone number, or viewing the pricing page. It is useful for behavioral analysis but should not always drive advertising optimization.

How Do You Know When an Event Can Be Used as a Primary Conversion?

It should be sufficiently close to the business outcome, occur regularly, and have a clear connection with revenue or a high-quality lead. If an action only shows user interest — such as a page view or form open — it is usually better kept as a micro-conversion for analytics.

Which Conversions Should Be Used in Google Ads?

Priority should be given to the deepest business conversion for which the system receives enough high-quality data. If there are too few sales to provide a stable signal, an earlier stage such as a qualified lead can be used temporarily.

When Is It Better to Optimize for a Qualified Lead Rather Than a Sale?

When sales are rare or sales data return to the advertising system with a significant delay. A qualified lead happens more often than a sale but reflects potential customer quality much better than a basic inquiry.

Should a Phone Click Be Counted as a Conversion?

As a behavioral event, yes. But a click does not guarantee that a call actually happened or that it was high quality, so a phone click should not automatically be treated as equivalent to a real inquiry or sale.

Can Advertising Be Optimized for Several Conversions?

Yes, if the actions genuinely have similar business value and correspond to the campaign objective. But mixing a purchase, form open, scroll, and phone click as equally valuable outcomes is risky because the advertising system receives an unclear signal.

What Is the Difference Between a Primary and Secondary Conversion?

A Primary conversion is used as a main goal for advertising optimization. A Secondary conversion remains available as a supporting event for monitoring and analysis and should not automatically have the same weight as the main business outcome.

Why Can a Large Number of Conversions in an Advertising Account Be Misleading?

Because the system may count actions with very different value at the same time: a purchase, inquiry, phone click, form open, or page view. If all of them have the same status, the number of conversions may increase and CPA may decrease without a corresponding increase in customers or sales.

Why Send CRM Data Back into Advertising Analytics?

CRM shows what happened after the first online conversion: whether the inquiry was relevant, whether it became an opportunity, and whether it resulted in a sale. Without these data, the advertising system may successfully optimize for cheap but low-quality inquiries. CRM feedback helps bring optimization closer to the real business outcome.

How Many Conversions Are Needed for Advertising Optimization?

There is no universal number. The required volume depends on the campaign type, conversion frequency, sales cycle length, and data stability. The practical principle is different: choose the deepest business conversion that occurs regularly enough for the system to learn from it.
