# CPA Optimization | Lowering Cost Per Conversion

[Oğuz Erol](https://oguzerol.com/en/about-me/)  |  2 min read

CPA (cost per acquisition/conversion), unlike [CPC](https://oguzerol.com/en/cpc-optimization/), measures not just the click but whether that click actually turned into a real conversion. Two accounts can run the same CPC and have very different CPAs — the difference lies in the post-click experience.

## Every funnel stage can leak

Loss happens at every step in the chain from click → page view → form/cart → completed conversion. Lowering CPA starts with finding where the biggest loss happens — sometimes the problem isn’t the ad, it’s the [landing page](https://oguzerol.com/en/landing-page-optimization/).

## Target CPA strategy needs data

The Target CPA smart bidding strategy bids based on historical conversion data; without enough conversion volume (generally at least 30 conversions a month), this strategy can produce unstable results.

## Low-quality conversions distort CPA

Not all conversions are equal — if spam form submissions or cancelled orders also count as “conversions,” CPA is calculated wrong. Filtering out conversion quality is the first step to seeing the real CPA.

**How we start.** We first review the conversion funnel end to end to identify where the loss is happening. Reach out via the [contact page](https://oguzerol.com/en/contact/).

## Frequently Asked Questions

### What’s the difference between CPA and ROAS?

CPA shows the cost of one conversion; [ROAS](https://oguzerol.com/en/roas-optimization/) shows how many times the budget spent came back as revenue. ROAS tends to be more meaningful for e-commerce, CPA for service businesses.

### When should I change my target CPA?

Even though the account enters a new learning period, changing the target too often prevents the algorithm from gaining stability; changes should be gradual and measured.

### How do offline conversions (phone-closed sales) factor into CPA?

With offline conversion import set up, phone-closed sales can be fed back into the system so the real CPA accounts for them too.

WHAT YOU CAN ASK FOR

## How do I work?
Work-hour packages

Tell me about your business and what you need on WhatsApp or by phone; we agree on **a work block of somewhere between 5 and 40 hours** and I start doing what is needed. What you get is not a calendar window — it is net working hours spent directly on your business. I can use 40 hours working three days straight, or deliberately spread it out and finish it over a year — whatever the work calls for. I do not spend my time estimating how long something will take, I spend it doing the work; every hour I spend leaves a lasting result in your business. We keep going for as long as you find it useful.

WORK BLOCKS

## Why not monthly?
Is 40 hours a week?

On a fixed monthly fee both sides are watching the wrong thing: you watch a fixed cost, the other side watches how many more contracts like this they can line up. Working by the hour puts us both in front of the same thing — the real value of the work that got done. I know not having an upfront answer to "how much will this cost in total?" is the natural cost of this model. But instead of paying a fixed fee for months to a setup that is not producing results, you only pay for the qualified time spent on your work — and you see exactly where that time went, start to finish. That is why my clients keep coming back.
