How much does the daily PPC budget affect the conversions available to us?

Budgets can be difficult to set, especially in new campaigns. Setting the budget too high or too low can lead to wasteful spending, machine learning issues, and other account performance issues.

This is why we need to spend this Ask PPC column to solve the relationship between budget, conversion and cost per purchase.

Asked Jack of Colchester.

“I often see that the daily budget is lower than the total cost per conversion. If there is enough budget every day, will the daily budget be higher than the cost per conversion?

For example, if our coffee machine costs £120 per conversion, does the daily budget matter?

Suppose we have a daily budget of £200 for 5 working days, a CPA of £120, and a daily budget of £333 for 3 days. Technically, I will get 1 per day on the fifth day and 2 per day on the third day. I may be thinking too much-I hope you can help. “

Basic rules of engagement

It is important to remember that the performance of daily, monthly, and lifetime budgets varies.

If you set a daily budget, the ad network will try to average your daily spend in 30.4 days. This may mean that the ad network will spend up to 200% of your daily budget on a given day.

Monthly and lifetime budgets allow greater fluctuations in daily expenditures, and in most cases will comply with the prescribed figures.

They are very suitable for those who need to spend a certain amount of money in a given time and can easily solve the problem Rising period For new campaigns.

Your cost-per-acquisition (CPA) depends on Conversions you designate as “converting”.

This number may surge because it contains too many or not enough conversion actions.

Minor conversion actions are not included in the reported CPA or Smart Bidding.

Impact of budget on conversions/CPA

Your actual cost is determined by the number of impressions and clicks. CPA and conversion rate tell you:

• Is your sales team/website completing the transaction?
• Have you configured for quality or flow?
• Can your budget support all goals?

In the problem example, there are some self-evident mechanisms:

• The advertiser received 8.34 conversions for £1,000.
• Individual conversions may have cheaper costs; however, the reported overall CPA factor accounts for the total cost divided by the total number of conversions.
• We don’t know how many clicks it takes to get 8 conversions.

The budget should be able to support at least 10 clicks in a day, because a 10% conversion rate is really good for search. The easiest way to see if you have enough budget is to see how many impressions you have lost due to budget.

If the budget is too low to support enough website clicks to trigger the conversion rate, the cost per conversion will increase.

Increasing your budget does not always reduce your cost per conversion. If the traffic quality is poor, the amount of fuel in the campaign is irrelevant.

Start with a Slightly higher budget for the first 60 days of the campaign Can help you obtain statistical significance of traffic quality.

In this way, any adjustments to the budget are based on the scaling of conversions, rather than troubleshooting intent.

When to change the budget vs.When to change channel

It’s important to know when a channel fits or doesn’t fit the budget.

Due to the high cost-per-click (CPC), a lower budget for paid search may result in a higher CPA.

Due to the lack of transaction focus, spending a large amount of budget on promotional activities (social positioning landing page visits, videos, etc.) may also have a higher cost per conversion.

Signs of insufficient budget:

• Top of page impression share is always less than 40%.
• The average cost-per-click exceeds 10% of the daily budget.
• The campaign strives to spend the budget consistently (that is, there are occasional spikes during the 30.4 day period).

The sign problem is the channel:

• Lead quality Is it bad or random.
• Increasing the budget will not help the CPA situation in any way.

take away

Your budget does not guarantee a certain number of conversions or cost-per-conversion. It powers your advertising campaign and provides you with impressions and clicks.

The budget of the event should only be changed if the event cannot support its designated goals.

I strongly recommend that you use the ad network budget report, which will help you predict what your budget can deliver.
