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.
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 | Paid | |
|---|---|---|
| What it is | Content that reaches people without ads | You pay the platform to deliver your message |
| Speed | Slow, builds over time | Fast, results from day one |
| Audience control | Limited | High: age, location, interests |
| Best for | Trust and brand building | Sales 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 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.
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.
These terms answer one question: how much did you pay for each thing you got?
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.
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.
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.
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.
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.
These terms answer two questions: is the ad working, and did the money come back?
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.
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.
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.
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.
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.
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.
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.
Every Meta campaign has 3 levels, and each level holds a different decision. TikTok, Google and Snapchat follow almost the same idea.
What do I want?
The objective, and the budget if you use CBOWho, where and when?
Audience, location, placements, schedule, and the budget if you use ABOWhat will people see?
Image or video, copy, headline, button, linkExample 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.
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.
| Objective | What the platform brings you | When to use it |
|---|---|---|
| Awareness | As many people as possible seeing the ad | A new brand that needs to get known |
| Traffic | People clicking through to your site | Rarely, it usually brings clicks that don't buy |
| Engagement | Interactions, plus WhatsApp and Messenger chats | Selling through messages, the most common model in Egypt |
| Leads | People filling in a form with their details | Real estate, clinics, courses, B2B |
| Sales | People buying on your website | When 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 (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.
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.
Targeting decides who sees your ad. There are 4 main types, from the coldest audience to the warmest:
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.People interested in a specific topic. Example: people interested in coffee and cafés.
When? At the start, on a new account with no data.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.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.
Without tracking, the platform doesn't know who bought, and you don't know which ad made the sale. You're spending blindfolded.
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.
Every important action a visitor takes is called an event. The key ones, in order:
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.
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.
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.
These mistakes burn more budget than any bad ad.
