A plain-English guide to understanding impressions, reach, CTR, ROAS, and every key metric in your Armanet dashboard.
What Every Metric in Your Dashboard Actually Means
Armanet endeavors to bring modern ad-tech to the 2A industry. For too long in the firearms industry, the extent of digital buys were direct placements that guaranteed a certain number of impressions. Then we came along and instantiated a platform that gives you a lot of data that goes way beyond impressions. Understandably, this can be a little overwhelming. You log into a dashboard full of acronym soup, and you don’t have time to do a self-started crash course on what it all means. This blog post is an attempt to remedy that.
Impressions
An impression is one ad served to one screen. Your ad loads on someone’s browser or phone, and that counts as a single impression. If your campaign delivered 500,000 impressions, that means your ad was displayed 500,000 times, not to 500,000 people, but 500,000 total instances of delivery. This is the base unit of digital advertising and what you are buying on a CPM basis.
Not all impressions are equal, which is where view impressions (viewable impressions) come in. A standard impression only confirms that the ad was served, not that it was actually seen. Ads can load below the fold or outside of the visible screen and still count. A view impression applies a stricter standard, meaning at least 50% of the ad was visible on screen for at least one second, or two seconds for video, giving it a real opportunity to be seen.
Impressions tell you how much scale your budget is driving, while view impressions tell you the quality of that delivery. In simple terms, impressions show how often your ad appeared, and view impressions show how often it had a chance to make an impact.
Reach
Reach is the number of unique people who saw your ad.
If your campaign delivered 500,000 impressions but your reach was 150,000, that means 150,000 individual people saw your ad, and on average, each one saw it about 3.3 times. That relationship between impressions and reach is called frequency.
Reach matters because it tells you how wide your net is. If you're launching a new product, you want high reach. You want as many potential buyers as possible to know it exists. If your reach is low but your impressions are high, you're showing the same ad to the same people repeatedly, which is a different strategy entirely.
Frequency
Frequency is how many times, on average, each unique person saw your ad. It’s simply impressions divided by reach.
Frequency is important to dial according to your goals. Too low, and people probably didn’t register your ad. Too high, and you’re wasting money showing ads to people who have already made a decision.
You will want to adjust your frequency based on your campaign type. For example, if you’re running retargeting campaigns, a higher frequency makes sense because you’re showing ads to people who have already demonstrated interest.
Click-Through Rate (CTR)
CTR is the percentage of impressions that resulted in a click. Someone saw your ad and clicked on it.
The formula is clicks divided by impressions. If you got 1,000 clicks on 500,000 impressions, your CTR is 0.2%.
That might sound low, but it’s not. Industry averages for display ads are often much lower. CTR tells you how relevant your ad is to your audience and how strong your creative is.
Low CTR with the right audience usually means your creative needs work. Strong CTR with low conversions usually points to issues with your landing page or product offering.
Return on Ad Spend (ROAS)
ROAS is revenue divided by ad spend.
If you spent $5,000 and generated $25,000 in revenue, your ROAS is 5x. That means every dollar you spent returned five.
ROAS is the most important metric, but it’s also incomplete. It only captures what can be directly tracked, and it doesn’t account for margins. A campaign can show strong ROAS but still not be profitable depending on your product margins.
CPM, CPC, and CPA
These are your cost metrics.
CPM is what you pay per thousand impressions. CPC is what you pay per click. CPA is what you pay per conversion.
Each of these helps you understand different parts of performance, but they only matter in context of your overall goals and revenue.
Viewability
Viewability measures whether your ad actually had the chance to be seen.
An ad is considered viewable if at least 50% of it was visible on screen for a minimum amount of time. This helps separate impressions that had a real chance to drive impact from ones that didn’t.
Time to Conversion
Time to conversion measures how long it takes someone to go from seeing or clicking an ad to making a purchase.
For lower-cost items, this might be quick. For higher-ticket items like firearms or optics, it can take weeks.
This metric is important because it gives context to performance. If you evaluate a campaign too early, you’re likely looking at incomplete data.
Common Questions
Why did performance dip this week? Most of the time it comes down to creative fatigue, seasonality, or increased competition.
Why did ROAS drop after scaling spend? As you expand to a broader audience, efficiency naturally decreases. That’s part of growth.
How long should you run a campaign before judging it? Typically at least two weeks for meaningful data, and longer for lower spend or upper-funnel campaigns.
What’s a good ROAS? It depends on your margins and goals, but generally, anything above 3x is solid, and above 5x is where scaling becomes a real opportunity.
The Big Picture
Every one of these metrics exists to answer one question: is your advertising achieving your business goals?
The mistake most advertisers make is looking at metrics in isolation. A high CTR doesn’t matter if nobody converts. A low CPM doesn’t matter if the audience is wrong. A strong ROAS doesn’t tell the full story if attribution is incomplete.
The dashboard tells a story.
Our job, yours and ours together, is to read that story correctly, pick up on the signals, and optimize accordingly.
