**Maximum Impressions**

You are able to view the total number of impressions that were generated by your ad. But what about the impressions that weren’t generated. Because your ad didn’t have a high enough rank or you didn’t have enough money?

A percentage is determined using the impression share measure by comparing the number of impressions. That were actually received to the number of impressions that were potentially available.

By combining the impression share statistic with the impressions metric, you will be able to determine. The maximum number of impressions that you might have obtained if both your advertising budget and your ad rank had been sufficiently high.

Insert the formula shown below into the section for the custom column:

## Maximum Possible

Maximum possible impressions are equal to the total impressions divided by the impression share.

Max Impressions

Max Impressions

It is helpful to be able to view the maximum number of impressions since. It provides you with an indication of the total search volume for a certain keyword. This search volume is in addition to the search volume that you are receiving as a result of your budget and ad rank.

Finding high-volume regions to optimize for can be easier if you have an accurate understanding of the overall number of searches performed for each term.

A bid estimate for one hundred percent of the impression share

You can make an estimate using the data on the impression share to determine. How much you would need to bid on a certain keyword in order to attain a share of 100 percent of the impressions.

## Calculate

To calculate this, simply divide your average cost-per-click by the percentage of total impressions received. According to the assumptions made by this method, an increase of one percent in CPC will lead to an increase of one percent in impression share.

Because this is not always the case, the formula cannot be considered flawless. However, it does provide you with an estimate of the amount of money you should be prepared to bid in order to win a share of 100 percent of the impressions.

The estimated bid for one hundred percent of the impression share equals the average cost per click for each impression.

Estimated Offer for One Hundred Percent of the Market Share of Impressions

The maximum number of clicks, cost, and conversions that are estimated

After you have determined the potential number of impressions you could have received. You can then estimate the potential number of clicks you could have received if your ad rank and budget had been sufficient.

To do this, we will first ascertain the maximum number of impressions that can be made. And then we will multiply that amount by your CTR. The following formula makes the assumption that increasing your bids to reach a 100% impression share will not result in an increase in your click-through rate (CTR). This is not always the case; if you increase your bid, it is possible that your advertisement may be displayed higher on the page.

## Increase In Your CTR

This may result in an increase in your CTR. However, you may still use the method to get a general idea of how many clicks you might anticipate receiving if your impression share is 100%.

Maximum predicted clicks are equal to impressions multiplied by the click-through rate (CTR).

Maximum Number of Clicks That Are Estimated

After you have a fundamental understanding of the method, you can put it to use to see. How you’re other metrics would change if you were to achieve a share of 100% of the impressions.

Combining the CTRs allows you to compute the total number of clicks that you would obtain. After that, you may compute how much more expensive your CPC would be by making use of the statistics for the average CPC and the impression share.

You can calculate how much your costs would increase if you achieved a 100% share of the impression market by multiplying your new cost-per-click by your new number of clicks.

Maximum anticipated cost equals (impressions divided by impression share) times’ click-through rate multiplied by average cost per click divided by impression share.

You may determine how many additional conversions you would get by first determining the number of clicks that you would receive and then multiplying that number by the conversion rate that you are now using in your business.

## Maximum Possible

Maximum possible conversions are equal to the product of the click-through rate multiplied by the number of impressions divided by the impression share.

After you have determined the maximum number of conversions possible, all you need to do to calculate the value of a conversion is multiply that number by the typical cost of an order (AOV).

Value divided by conversion is the preset metric that Google Ads already has for your average order value (AOV). Because of this, you do not need to manually calculate your AOV anymore.

Maximum expected conversions = (((impressions / impression share) * CTR) * Conv. Rate) * value / conv

CPA or ROAS estimates based on a total share of 100 percent impressions

You have performed the calculation necessary to determine the number of conversions you would obtain if you aimed an impression share of one hundred percent. How does this influence the profitability of your account?

If you sought to get a hundred percent of the impression share, here is how you would compute the anticipated cost per action and return on investment for your account.

## CTR

The maximum estimated cost per acquisition is calculated as follows: Maximum estimated CPA = ((impressions / impression share) * CTR) * (average CPC / impression) / ((impressions / impression share) * CTR) * Conversion Rate

Maximum projected ROAS = (Conv. Value / Conversions) / (((impressions / impression share) * CTR) * (average CPC / impression))

The estimated volume of lost business

You have the option of looking at the estimated total number of impressions that you did not obtain because either your ad rank or your budget was not high enough. This is an alternative to looking at the projected total number of impressions that you could have received.

You can accomplish this by making a few tweaks to the algorithm used to estimate the total number of impressions.

Total estimated impressions lost = (impressions / impression share) – impressions

Amount of Potentially Lost Impressions

Amount of Potentially Lost Impressions

It is possible to modify the aforementioned formula in order to compute all of the other metrics that have been covered in this blog. These are the following:

**Conversion value CPA ROAS**

The estimated number of impressions at a given percentage of total impressions

If you need to reach a particular impression share for one of your campaigns, all you need to do is alter the formulae that have been presented above so that they include the needed amount of impression share.

Using the formula below, you can compute the total number of impressions you would receive if your impression share was 65%. It computes the number of impressions you may anticipate receiving if you held a proportion of the whole audience equal to one hundred percent. After that, it takes the total number of impressions and multiplies it by the percentage of impression share that you wish to accomplish.

The formula for estimating the number of impressions for a share of 65 percent is: (impressions / impression share) * 0.65.

You may use the same fundamental concept to calculate various metrics that you would expect for a certain impression share, such as the number of clicks, the cost, and the number of conversions, to name just a few.
