How to read an ad report: the metrics that matter

Visibility metrics: impressions, reach, frequency

Impressions show how many times your ad was displayed. Reach, used mostly on social networks, shows how many different people saw it. Frequency is the average number of impressions per person.

These numbers tell you whether your ad is reaching people, but not whether it brings customers. Frequency climbing steadily on the same audience may mean people are seeing the same ad too often and it's time for fresh creative.

Interest metrics: clicks, CTR, CPC

Clicks show how many people tapped or clicked your ad. CTR (click-through rate) is the share of impressions that turned into clicks: clicks divided by impressions. A better CTR than before usually means the ad is more relevant to the people seeing it.

CPC (cost per click) is what you pay on average for a click: spend divided by clicks. On social networks you'll also often see CPM, the cost per thousand impressions.

A low CPC doesn't automatically mean a good campaign. Cheap clicks that never lead to sales are still wasted money.

Money metrics: conversions, CPA, ROAS

Conversions are the actions you consider valuable: an order, a form, a call. They only appear in reports if conversion tracking is set up correctly on your site or app. Without it, every other number is only part of the story.

Conversion rate is the share of clicks that become conversions. Lots of clicks and few conversions may point to the landing page, the offer or the audience rather than the ad itself.

CPA (cost per acquisition, or cost per conversion) is spend divided by conversions. Compare it with the most you can pay for a customer, based on your margin (see our guide to a small business ad budget).

ROAS (return on ad spend) is the sales value attributed to ads divided by spend. It's most useful for online shops that send order values to the platform. Note that ROAS is based on revenue, not profit, so your break-even point depends on your margin.

Reading the metrics together

A single metric viewed in isolation can mislead. Look at the whole chain: impressions, clicks, conversions, cost. A few typical situations:

• Many impressions, weak CTR: the ad isn't appealing or is reaching the wrong people. Check copy, creative and targeting.
• Good CTR, few conversions: people are interested, but something stops them on your site. Check the landing page, price, speed and form.
• Conversions, but CPA too high: the campaign delivers, but too expensively. Look for searches or audiences that spend without results; see also negative keywords.
• Spend rising with no extra conversions: the extra budget may be reaching less interested people.

Mind attribution and the date range

Each platform decides by its own rules which ad gets credit for a conversion, and the same sale can appear in several networks' reports. As a result, the total conversions reported across platforms can exceed your real number of orders. Compare regularly with sales from your shop or CRM.

The date range matters too: conversions can be recorded with a delay, so the most recent days may look weaker than they are. Compare equal periods (a week with the previous week, a month with the previous month) and allow for seasonality. Details on attribution models are in the Google Ads Help Center and the Meta Business Help Center.

A 15-minute weekly routine

1. Check total spend against your planned budget.
2. Look at conversions and CPA for each campaign, compared with last week.
3. Identify your best and weakest campaign.
4. For search campaigns, go through new search terms and add the negatives you need.
5. Write down what you changed and why, so you can track the effect next week.

A short routine done consistently helps more than a long analysis done rarely. If you run campaigns on several networks, a clear structure makes reports much easier to read; see our guide to ad campaign structure.

Plain-language reports with adscontrol.ai

If you'd rather not dig through tables, in adscontrol.ai you can simply ask: “report for last week” or “how are campaigns doing compared with last month?”. The assistant reads data from your connected accounts (Google Ads, Meta, TikTok, LinkedIn, X or Pinterest), compares it with the previous period and explains what works, what doesn't and what you could do next.

Any recommendation that changes something in your account appears as a proposal you confirm. See the plans on the pricing page or create a free account and ask for your first report.
