Impressions

The total number of times your ad was displayed on screen. The same person can see your ad multiple times: each display counts as one impression.

Example: 100,000 impressions doesn't mean 100,000 people. It means your ad was displayed 100,000 times, possibly to 30,000 people who each saw it an average of 3 times.


Reach

The number of unique people who saw your ad. Unlike impressions, each person is counted only once, regardless of how many times they saw the ad.

Impressions vs Reach

If you have 100,000 impressions and a reach of 30,000, it means each person saw your ad approximately 3.3 times on average. This is called frequency.


Clicks

The number of times someone clicked on your ad. This includes clicks to your website or landing page.


CTR: Click-Through Rate

The percentage of people who clicked on your ad among those who saw it. It measures how much interest your ad generates.

CTR = (Clicks / Impressions) x 100

Example: 500 clicks on 25,000 impressions = CTR of 2%

CTRInterpretation
Below 1%Low: the visual or copy isn't engaging enough
1% to 2%Average: in the norm for most industries
Above 2%Good: your ad generates above-average interest

TIP

CTR is one of the best indicators of your ad creative quality. A declining CTR over time often means your audience has seen the same ad too much and it needs refreshing.


CPC: Cost per Click

The average amount you pay each time someone clicks on your ad.

CPC = Ad Spend / Clicks

Example: $2,000 spent for 800 clicks = CPC of $2.50

INFO

A lower CPC means you're driving traffic at lower cost. But a low CPC with a low conversion rate isn't a win: traffic quality matters as much as price.


CPM: Cost per Thousand Impressions

The cost to display your ad 1,000 times. It's an indicator of the price of visibility in your target market.

CPM = (Ad Spend / Impressions) x 1,000

Example: $3,000 for 200,000 impressions = CPM of $15

CPM varies based on competition for your target audience. During peak periods (Black Friday, year-end), CPMs rise because more advertisers are competing for the same attention.


ROAS: Return on Ad Spend

The return on your advertising spend. It tells you how many dollars of revenue each dollar of ads generated.

ROAS = Revenue / Ad Spend

Example: $25,000 in revenue with $7,000 in ads = ROAS of 3.57x

ROASInterpretation
Below 1xYou're losing money: each ad dollar returns less than a dollar
1x to 2xCritical threshold: margins are very thin
2x to 4xHealthy: good profitability for most businesses
Above 4xExcellent: strong ad profitability

Recommended Target

Aim for a ROAS above 2x at minimum. The ideal target depends on your product margins, but 2x is the floor for most business models.


Ad Waste

The system analyzes all your individual ads to identify those spending budget without generating results. Waste occurs when an ad has spent a significant amount without producing conversions.

How It Works

An ad is flagged as waste when it has spent a considerable budget without generating the expected results (leads, applications, bookings, or sales). The system compares each ad's spend to the average performance to determine which ones are underperforming.

What You See in the Dashboard

Ads identified as waste are listed with:

  • The ad name
  • The amount spent
  • The lack of results over the period

Why It Matters

Without this analysis, an ineffective ad can silently spend hundreds of dollars per day. Automatic waste identification lets you react quickly: pause the ad, change the creative, or adjust the audience.

How to Act

When an ad is identified as waste:

  1. Check if it's a recent ad that hasn't had time to perform yet (give at least 48-72 hours and a minimum budget before judging)
  2. Compare with ads that are performing well: what's different?
  3. Decide: pause the ad, modify the visual or copy, or adjust the target audience

How Metrics Are Connected

Ad metrics are interconnected. Here's how they influence each other:

If...Then...Possible Action
CPM risesCPC also rises (more expensive to be seen)Test new audiences
CTR dropsCPC rises (more impressions needed per click)Refresh creatives
ROAS dropsProfitability decreasesCheck the full funnel, not just ads
CPC stable but conversions dropProblem is after the click (page, form)Optimize the landing page

TIP

Never look at a single metric in isolation. A rising CPC isn't a problem if ROAS is also rising: it means you're paying more per click, but those clicks are worth more.
