Come, let’s explain in simple terms what CPA and OCPC are.

Ever since Toutiao launched the CPA and OCPC models, many friends have been eager to try them out. However, as I was investing, I discovered a problem: what is the difference between CPA and OCPC?

Today I will tell you what the difference is between the two!

Let’s talk about CPA first:

Regarding various common billing methods, Ai Qijun once shared with everyone an easy-to-understand story of "Director looking for a small card when staying in a hotel". Check out the historical articles: Director explains CPC, CPM, CPA, CPS, CPL, CPD, CPR... I couldn't help laughing! What about moral integrity?

Let’s take a look at Toutiao’s explanation:

That is, payment is made based on the user's behavior on the landing page .

Toutiao’s CPA model was launched in the first half of this year. It is only aimed at SMBs (small and medium-sized customers) and not KAs (large customers)!

So, take a look at your background. If there is a CPA model directly, then congratulations, you are small or medium-sized. If not, but you want to invest in CPA, you can go to the consultant who opened the account for you in the branch to see if you can apply.

Let’s talk about OCPC:

This is a billing method introduced to improve optimization. It is divided into the first stage and the second stage. Its essence is still CPC , which is the biggest difference from CPA.

Look at the explanation of the headlines:

It enables advertisers to place advertisements more scientifically and with greater targeting, helping them to obtain more high-quality traffic and thus improve conversions .

Comparison of bidding ranking and billing logic:

Don’t you understand?

To put it bluntly, no matter what bidding method you use, the basis for the system to ultimately determine the bidding ranking is CPM!

The above figure shows the formula for calculating CPM in different ways.

Let’s look at a case:

You see, no matter which delivery method is used, the larger the final CPM, the higher the ranking will be. In other words, the essence of information flow is to play CPM, but most people can't play it well. Therefore, in order to help advertisers further optimize, the platform will find ways to introduce different billing methods.

Comparison of the advantages and disadvantages of CPA and OCPC:

1. CPA is only open to SMBs (small and medium-sized clients), while OCPC is open to all advertisers;

2. CPA has no usage threshold, while OCPC is divided into the first and second stages. In the first stage, you cannot choose to charge by conversion;

3. CPA is charged based on conversions to avoid model fluctuations. OCPC is ranked based on conversions, but is still charged based on clicks.

Okay, the above is an interpretation of the two billing methods of CPA and OCPC. Do you understand it now?
