The Media Buyer'sAds Glossary

Every term you need to understand before you spend a single pound on paid ads, explained in plain language with real examples. For each term: the definition, the formula, an example, and my honest take.

01

The basics

Media Buyer

What is a media buyer?

The person who turns an ad budget into customers and sales. They pick the platform, define the audience, split the budget, and watch the numbers every day to decide: spend more, stop, or change the ad.

My take: A good media buyer isn't the one who knows every button in Ads Manager. It's the one who understands the business: the profit margin, the average order value, and how much the client can afford to pay for each customer.

Organic vs. paid

OrganicPaid

Best forTrust and brand buildingSales and leads

My take: They work together. Ads bring people to your page, and organic content is what convinces them to buy. A strong ad pointing to an empty page is money down the drain.

The funnel

The funnel is the journey a customer takes from the first time they see you until they buy. It's called a funnel because fewer people make it through each stage.

TOF · Top of funnelDoesn't know you yetGoal: awareness and reach · Example: a Reel about the problem
MOF · Middle of funnelKnows you and is comparingGoal: engagement and visits · Example: product demo and reviews
BOF · Bottom of funnelReady to buyGoal: sales · Example: a time-limited offer + "Order now"

My take: The most common mistake I see is a "Buy now" ad shown to people who've never heard of the brand. Every stage needs a different message.

02

Cost metrics

These terms answer one question: how much did you pay for each thing you got?

CPM

Cost per 1,000 impressions

What you pay for your ad to be shown 1,000 times.

CPM = (Amount spent ÷ Impressions) × 1,000

Example: You spent 500 EGP and your ad was shown 20,000 times. CPM = 25 EGP.

My take: CPM measures how expensive the audience is, not how good your ad is. It rises in peak seasons like Ramadan and Black Friday because competition goes up. A high CPM is fine if it's bringing in sales.

CPC

Cost per click

What you pay for each click on your ad.

CPC = Amount spent ÷ Clicks

Example: You spent 500 EGP and got 250 clicks. CPC = 2 EGP.

My take: Know the difference between Link Clicks (clicks on your link) and All Clicks (any click, even on the page name). Always calculate on Link Clicks.

CPA

Cost per result

What you pay for each result you want: a purchase, a sign-up, or a message. Facebook calls it Cost per Result.

CPA = Amount spent ÷ Results

Example: You spent 3,000 EGP and got 20 orders. CPA = 150 EGP per order.

My take: This is the most important number you'll track. But you need to know the highest CPA you can afford before you start: if you make 100 EGP profit per order, a 150 EGP CPA is a loss, however good it looks.

CPL

Cost per lead

A type of CPA where the result is someone leaving their details (name and phone) or sending a message. Common in real estate, clinics and courses.

CPL = Amount spent ÷ Leads

Example: You spent 2,000 EGP and got 80 leads. CPL = 25 EGP.

My take: A cheap lead who never answers the phone costs more than an expensive lead who buys. Ask the sales team how many out of every 10 leads actually bought, and judge on that.

CAC

Customer acquisition cost

The full cost of winning a new paying customer. It includes ads plus every other marketing cost, like production, the sales team and tools.

CAC = Total marketing costs ÷ New customers

Example: You spent 10,000 EGP on ads and 5,000 on production and tools, and won 50 new customers. CAC = 15,000 ÷ 50 = 300 EGP.

My take: The difference between CPA and CAC is the difference between a media buyer and a business owner. One measures the ad; the other measures the whole business.

03

Performance metrics

These terms answer two questions: is the ad working, and did the money come back?

Impressions · Reach

Impressions and reach

Impressions: the total number of times your ad was shown. Reach: the number of different people who saw it.

Example: Ahmed saw your ad 3 times. That's 3 impressions and 1 reach.

Frequency

Frequency

The average number of times each person saw your ad.

Frequency = Impressions ÷ Reach

Example: 30,000 impressions ÷ 10,000 people = frequency of 3.

My take: When frequency climbs and results drop, that's ad fatigue. People are tired of the same ad. Change the creative, not the targeting.

CTR

Click-through rate

Out of every 100 people who saw the ad, how many clicked it.

CTR = (Clicks ÷ Impressions) × 100

Example: 200 clicks from 20,000 impressions = CTR of 1%.

My take: CTR is the health check for your creative. If it's low, the ad isn't stopping people: change the image or the first 3 seconds of the video.

CR

Conversion rate

Out of every 100 people who landed on your site or page, how many bought or signed up.

CR = (Results ÷ Visitors) × 100

Example: 200 visitors and 6 orders = CR of 3%.

My take: If CTR is good and CR is weak, the problem isn't the ad. It's the page, the price, the offer, or how fast you reply to messages.

ROAS

Return on ad spend

How much revenue each pound of ad spend brought back.

ROAS = Revenue ÷ Ad spend

Example: You spent 5,000 EGP and made 20,000 EGP in sales. ROAS = 4 (or 4x).

My take: A 4x ROAS isn't always profit. With a 20% margin, 20,000 in sales gives you only 4,000 profit, so you lost 1,000. Work out your break-even ROAS before any campaign.

Break-even ROAS

Break-even ROAS

The lowest ROAS you need to avoid losing money.

Break-even ROAS = 1 ÷ Profit margin

Example: 20% margin → you need ROAS above 5 to profit. 50% margin → anything above 2 works.

Try it with your numbers: the free profit calculator works out your break-even point in seconds.

ROI

Return on investment

What you actually earned after all costs, as a percentage of what you spent.

ROI = ((Profit − Cost) ÷ Cost) × 100

Example: You spent 5,000 EGP on ads, and gross profit on the sales (after cost of goods) was 8,000. ROI = 60%.

My take: ROAS is the media buyer's number; ROI is the owner's number. If you want a client's trust, talk to them in ROI.

04

Campaign structure

Every Meta campaign has 3 levels, and each level holds a different decision. TikTok, Google and Snapchat follow almost the same idea.

Campaign

Campaign

What do I want?

The objective, and the budget if you use CBO
Ad Set

Ad set

Who, where and when?

Audience, location, placements, schedule, and the budget if you use ABO
Ad

Ad

What will people see?

Image or video, copy, headline, button, link

Example for a clothing store: one Sales campaign, with one ad set for Cairo and one for Alexandria, each running 3 ads: a video, an image and a carousel.

Campaign objectives

The objective is the most important decision in a campaign, because the platform goes looking for the people most likely to do exactly what you asked for.

ObjectiveWhat the platform brings youWhen to use it
AwarenessAs many people as possible seeing the adA new brand that needs to get known
TrafficPeople clicking through to your siteRarely, it usually brings clicks that don't buy
EngagementInteractions, plus WhatsApp and Messenger chatsSelling through messages, the most common model in Egypt
LeadsPeople filling in a form with their detailsReal estate, clinics, courses, B2B
SalesPeople buying on your websiteWhen you have a site with a properly connected pixel

My take: Pick the objective that equals money for you. If you want sales and choose Traffic because it's "cheaper", the platform will give you exactly what you asked for: cheap clicks that don't buy.

CBO · ABO

Campaign vs. ad set budget

CBO (now called Advantage+ Campaign Budget): you set the budget at campaign level and the platform moves it to the best-performing ad sets. ABO: you set a fixed budget per ad set and stay in control.

My take: Use ABO for testing, so every audience gets a fair shot. Use CBO for scaling once you know what wins, and let the platform do its job.

Learning Phase

Learning phase

In the first days of any new ad set, the platform experiments to learn who responds. It ends once you get about 50 results within 7 days.

My take: Don't touch the campaign for the first 3 days. Any big change, like moving the budget by more than 20%, changing targeting or adding a new ad, sends it back to the start of learning.

05

Targeting

Targeting decides who sees your ad. There are 4 main types, from the coldest audience to the warmest:

Broad

Broad targeting

Everyone by age and location only, with no interests. Example: women 22–45 in Egypt.

When? Once your pixel has enough data and your creative is strong.
Interests

Interests

People interested in a specific topic. Example: people interested in coffee and cafés.

When? At the start, on a new account with no data.
Lookalike

Lookalike audience

New people who resemble your customers. 1% is the closest match and smallest; 10% is wider and less precise.

When? Once you have a real customer list.
Custom · Retargeting

Retargeting

People who already know you: visited your site, watched 75% of a video, or added to cart and left.

When? Always. These are your cheapest sales.

My take: A lookalike is only as good as its source: one built from buyers beats one built from people who liked a post. Beginners spend hours on interests; pros spend them on creative. Today, the creative is the targeting: an ad made for mothers brings mothers, even on Broad.

06

Tracking

Without tracking, the platform doesn't know who bought, and you don't know which ad made the sale. You're spending blindfolded.

Pixel

The pixel

A small piece of code on your website that tells Meta (or TikTok, or Snapchat) everything a visitor does.

My take: The pixel isn't just for reporting. It's how the platform learns who your customer is, and every day without it is data you'll never get back.

Events

Events

Every important action a visitor takes is called an event. The key ones, in order:

  1. PageView Opened a page
  2. ViewContent Viewed a product
  3. AddToCart Added to cart
  4. InitiateCheckout Started checkout
  5. Purchase Actually bought
  6. Lead Left their details

My take: Your Purchase event must send the order value and currency (for example 850 EGP), or you'll never be able to calculate ROAS.

CAPI

Conversions API

A way to send events straight from your server instead of the visitor's browser. It matters because ad blockers and iPhone privacy updates break the pixel, and part of your sales go missing. CAPI fills that gap.

My take: Use both together: Pixel + CAPI. Most platforms, like Shopify and WooCommerce, connect CAPI in a click.

UTM

Tracking links

Tags you add to the end of a link so Google Analytics knows where a visitor came from.

site.com/offer?utm_source=facebook&utm_medium=paid&utm_campaign=ramadan_sale

My take: Ads Manager always grades its own homework. UTMs give you an independent view to compare platforms fairly.

07

Beginner mistakes

These mistakes burn more budget than any bad ad.

  1. Starting without knowing your maximum CPA. Work out your profit margin first, then decide how much you can pay per order.
  2. Judging a campaign after one day. Wait 3 to 7 days, or until you've spent about twice your target CPA with no result.
  3. Tweaking every day. Every big change sends the campaign back to the learning phase.
  4. Hitting "Boost Post". The boost button is built for engagement, not sales. Always work from Ads Manager.
  5. Running a single ad. Put 3 to 5 different ads in each ad set and let the platform find the strongest.
  6. Splitting a small budget across dozens of ad sets. 100 EGP a day over 10 ad sets means none of them will learn. Concentrate your budget.
  7. Blaming the ad for a sales problem. Slow replies, a slow website, or a price above the market will sink the best ad.
  8. Not installing the pixel on day one. Data you don't record today is gone for good.
  9. Copying competitors' ads word for word. Get inspired by the Ads Library, but your brand, offer and audience are different.
  10. Measuring success in likes. Likes don't pay salaries. Sales and profit do.
