Meta Ads interview terminologies are the vocabulary every aspiring digital marketer must know before walking into a paid media job interview. From Campaign Objective to ROAS, recruiters expect candidates to define each term clearly and explain how it fits into the Meta advertising ecosystem.
This guide breaks down 72 beginner-level Meta and Facebook Ads terminologies in plain English — exactly the way they get asked in interviews. Whether you are preparing for a junior performance marketer role, a paid media internship, or a digital marketing executive position, this glossary will give you confident, jargon-free answers.

Why Learn Meta Ads Terminologies for Interviews
Meta (the parent company of Facebook, Instagram, Messenger, and WhatsApp) runs one of the largest advertising platforms in the world. According to Meta’s own reporting, more than 10 million advertisers use its platforms every month. For any digital marketing job in India — especially in agencies, D2C brands, and SaaS companies — Meta Ads fluency is non-negotiable.
Interviewers test three things:
- Do you understand the structure of a Meta Ads campaign?
- Can you define key metrics like CPM, CTR, CPC, CPA, and ROAS?
- Do you know how tracking works (Pixel, Conversions API, Events Manager)?
This glossary covers all three areas in one place.
Meta Ads Platform Basics (Terms 1–10)
1. Meta Ads
Meta Ads is the paid advertising system run by Meta Platforms Inc. It allows advertisers to run ads across Facebook, Instagram, Messenger, WhatsApp, and the Audience Network from a single account.
2. Facebook Ads
Facebook Ads is the original name of Meta’s advertising product. It is still widely used in interviews and job descriptions to refer to ads shown on the Facebook platform. Today, Facebook Ads is a subset of Meta Ads.
3. Meta Ads Manager
Meta Ads Manager is the primary tool used to create, manage, and analyse paid ad campaigns. It is where advertisers set up campaigns, ad sets, and ads, and where they track performance metrics.
4. Meta Business Suite
Meta Business Suite is a free dashboard that lets businesses manage their Facebook Page, Instagram account, messages, posts, and basic ads in one place. It is suited for small businesses, while Ads Manager is for advanced campaign management.
5. Business Manager
Business Manager (now part of Meta Business Suite) is the centralised platform where agencies and brands manage multiple Pages, ad accounts, Pixels, and team members securely.
6. Ad Account
An Ad Account is the billing and operational entity inside Business Manager where campaigns are created and payments are processed. One Business Manager can hold multiple Ad Accounts.
7. Campaign
A Campaign is the top level of the Meta Ads structure. At this level, the advertiser chooses the Campaign Objective — the business goal the ads should achieve.
8. Campaign Objective
The Campaign Objective tells Meta what outcome you want — Awareness, Traffic, Engagement, Leads, App Promotion, or Sales. Meta’s algorithm optimises delivery based on this choice.
9. Ad Set
An Ad Set sits one level below the campaign. It defines the audience, placements, budget, schedule, and optimisation event for a group of ads.
10. Ad
An Ad is the actual creative unit that users see — the image, video, headline, copy, and call-to-action button. Each ad sits inside an ad set.
Ad Creative and Copy Terms (11–16)
11. Ad Creative
Ad Creative refers to the visual element of the ad — image, video, carousel, or collection. Strong creative is the single biggest driver of ad performance on Meta.
12. Primary Text
Primary Text is the main copy that appears above the image or video in a Meta ad. It is limited to around 125 characters before getting truncated with a “See More” link.
13. Headline
The Headline is the short, bold text that appears below the creative. It is typically used to highlight the offer, hook, or value proposition. Meta recommends keeping it under 40 characters.
14. Description
The Description is the smaller text that appears below the headline. It supports the headline with additional context or offer details. It is often only visible on certain placements.
15. Call-to-Action (CTA)
The Call-to-Action is the button on the ad — for example, “Shop Now”, “Learn More”, “Sign Up”, or “Get Quote”. The CTA tells the user what to do next and links to the destination URL.
16. Destination URL / Landing Page
The Destination URL is the web address the user is sent to after clicking the ad. The page itself is called the Landing Page. A poorly designed landing page is one of the top reasons Meta Ads underperform, even when the ad creative is strong.
Audience and Targeting Terms (17–26)
17. Audience
An Audience is the group of users Meta will show your ad to. Audiences are configured inside the Ad Set level.
18. Targeting
Targeting is the process of defining which users should see your ads — based on location, age, gender, interests, behaviours, or custom data.
19. Core Audience
A Core Audience is built using Meta’s basic targeting filters — demographics, location, interests, and behaviours. It is the default starting point for new advertisers.
20. Custom Audience
A Custom Audience is built from your own data — website visitors (via Pixel), customer lists (CSV upload), app users, video viewers, or people who engaged with your Facebook or Instagram account.
21. Lookalike Audience
A Lookalike Audience is a new audience that Meta creates by finding users similar to an existing Custom Audience (for example, similar to your best customers). It usually delivers stronger performance than cold core audiences.
22. Advantage+ Audience
Advantage+ Audience is Meta’s AI-powered targeting option that uses machine learning to find the most likely converters automatically, with minimal manual targeting input. It is the new default in 2025.
23. Saved Audience
A Saved Audience is a reusable set of targeting parameters (interests + demographics + locations) that you store inside Ads Manager so you don’t have to rebuild it each time.
24. Detailed Targeting
Detailed Targeting allows advertisers to narrow audiences using interests, behaviours, and demographic categories. Meta has been reducing the granularity of Detailed Targeting since 2022 due to privacy changes.
25. Demographics, Interests, and Behaviours
Demographics include age, gender, education, job title, and relationship status. Interests reflect what users engage with (pages liked, topics followed). Behaviours are based on user actions — purchase patterns, device usage, or travel habits.
26. Placements
Placements refer to where your ad is shown across Meta’s network. Placements can be selected manually or left to Meta’s AI through Advantage+ Placements.
Placement Types (27–32)
27. Advantage+ Placements
Advantage+ Placements (formerly Automatic Placements) let Meta’s system distribute your ads across all available placements to find the cheapest results. This is the recommended option for most beginners.
28. Facebook Feed
Facebook Feed is the main scrolling feed on Facebook. Ads here appear between organic posts and support all formats — image, video, carousel, and collection.
29. Instagram Feed
Instagram Feed ads appear in the main Instagram scrolling feed. Square (1:1) and vertical (4:5) creatives perform best here.
30. Reels Ads
Reels Ads are short, full-screen vertical video ads shown between organic Reels on Facebook and Instagram. They have become one of the highest-engagement placements.
31. Stories Ads
Stories Ads are full-screen vertical ads (9:16) that appear between users’ Stories on Facebook and Instagram. They support image and short video formats.
32. Audience Network
Audience Network is Meta’s network of third-party apps and websites where ads can be shown outside Facebook and Instagram. It typically delivers cheaper impressions but lower-quality traffic.
Budget and Bidding Terms (33–38)
33. Budget
Budget is the amount of money allocated to a campaign or ad set. Meta uses the budget as a constraint while the algorithm decides how to spend it.
34. Daily Budget
A Daily Budget is the average amount Meta will spend per day on a campaign or ad set. Actual daily spend can vary by ±25%.
35. Lifetime Budget
A Lifetime Budget is the total amount Meta will spend over the entire schedule of a campaign. Meta distributes the spend based on expected opportunity each day.
36. Advantage Campaign Budget (CBO)
Advantage Campaign Budget (previously CBO – Campaign Budget Optimisation) lets Meta automatically distribute the budget across ad sets based on which ones are likely to perform best.
37. Ad Set Budget (ABO)
Ad Set Budget (ABO – Ad Set Budget Optimisation) means the budget is fixed at the ad set level. The advertiser controls how much each audience or ad set spends.
38. Bid Strategy / Cost Per Result Goal / Bid Cap
A Bid Strategy tells Meta how aggressively to bid in the ad auction. Cost Per Result Goal sets a target average cost per outcome. Bid Cap sets a hard upper limit Meta cannot exceed in any single auction.
Auction and Delivery Terms (39–43)
39. Ad Auction
The Ad Auction is the system Meta uses to decide which ad to show to which user. It scores each ad on three factors — bid amount, estimated action rate, and ad quality.
40. Learning Phase
The Learning Phase is the period during which Meta gathers data on a new ad set to find the right audience and optimisation pattern. An ad set typically needs 50 optimisation events within 7 days to exit Learning Phase.
41. Learning Limited
Learning Limited is a status shown when an ad set cannot collect 50 events within 7 days. This usually means budget is too low, audience is too narrow, or there are too many ads competing for spend.
42. Delivery
Delivery is Meta’s term for how (and where) your ads are being shown. Common delivery statuses include Active, Learning, Learning Limited, Inactive, and Not Delivering.
43. Optimisation Event
The Optimisation Event is the action Meta is trying to drive at the ad set level — Link Clicks, Landing Page Views, Add to Cart, Purchase, Lead, etc. Meta’s algorithm optimises delivery toward people most likely to take this action.
Tracking, Pixel, and Events (44–53)
44. Conversion Event
A Conversion Event is a meaningful action a user takes on your website or app — such as a purchase, signup, or lead form submission. Conversion events are tracked using the Meta Pixel or Conversions API.
45. Meta Pixel
The Meta Pixel is a small JavaScript code installed on your website that tracks visitor behaviour and reports it back to Meta. It powers retargeting, conversion tracking, and Lookalike Audience creation.
46. Conversions API (CAPI)
The Conversions API is a server-side tracking method that sends events directly from your server to Meta. It is more reliable than the Pixel because it is not affected by browser blockers, iOS privacy changes, or ad blockers.
47. Events Manager
Events Manager is the section inside Meta Business Suite where advertisers set up, monitor, and troubleshoot Pixel events, Conversions API events, and Offline events.
48. Standard Events
Standard Events are a predefined list of actions Meta recognises by default — Purchase, Lead, ViewContent, AddToCart, InitiateCheckout, CompleteRegistration, Contact, and Subscribe.
49. Custom Events
Custom Events are user-defined events that aren’t part of the Standard Event list. They are useful for tracking unique business actions like “Booked Demo” or “Downloaded Brochure”.
50. Purchase Event
The Purchase Event fires when a user completes a transaction. It is the most important event for e-commerce and direct-response advertisers because it directly powers ROAS reporting.
51. Lead Event
The Lead Event fires when a user submits a lead form — either on your website or via Meta’s native Instant Forms. Critical for service businesses, real estate, education, and B2B advertisers.
52. Add to Cart Event
The Add to Cart Event fires when a shopper adds a product to their cart on your e-commerce site. It is a mid-funnel signal used heavily for retargeting and Lookalikes.
53. View Content Event
The View Content Event fires when a user views a product or key page on your site. It is the most common upper-funnel tracking event and feeds Meta’s algorithm with audience interest data.
Attribution and Measurement (54–55)
54. Attribution Setting
The Attribution Setting determines how a conversion is credited to an ad. Meta currently offers options like 1-day click, 7-day click, and 1-day view, all configured at the ad set level.
55. Attribution Window
The Attribution Window is the time period during which a conversion is counted after a user clicks or views an ad. Default is 7-day click and 1-day view for most accounts since iOS 14.5 changes.
Key Performance Metrics (56–66)
56. Impression
An Impression is counted each time your ad is displayed on a user’s screen. One user can generate multiple impressions in a single session.
57. Reach
Reach is the number of unique users who saw your ad at least once. It is always lower than or equal to impressions.
58. Frequency
Frequency is the average number of times each unique user saw your ad. Formula: Impressions ÷ Reach. High frequency without conversions usually signals ad fatigue.
59. CPM (Cost Per Mille)
CPM is the cost to deliver 1,000 impressions. Formula: (Spend ÷ Impressions) × 1,000. It is the most basic measure of how expensive a platform or audience is.
60. CPC (Cost Per Click)
CPC is the average cost paid for each click on your ad. Formula: Spend ÷ Clicks. Meta reports two CPC values — All Clicks and Link Clicks.
61. CTR (Click-Through Rate)
CTR is the percentage of people who clicked your ad after seeing it. Formula: (Clicks ÷ Impressions) × 100. A healthy CTR for cold traffic on Meta is generally 1% or above.
62. Link Clicks
Link Clicks count only the clicks that lead to a destination URL (your landing page or app store). They exclude likes, comments, and shares.
63. Landing Page Views (LPV)
A Landing Page View is counted when a user clicks the ad and the destination page fully loads. LPVs are always lower than Link Clicks — the gap reveals page speed or drop-off issues.
64. Leads / Cost Per Lead (CPL)
A Lead is a user who submits their contact details via a form. Cost Per Lead = Spend ÷ Leads. CPL is the key efficiency metric for service businesses and education brands.
65. Cost Per Purchase / CPA
Cost Per Purchase is the average amount spent to generate one purchase. CPA (Cost Per Acquisition) is the broader version — cost to acquire one customer or one defined conversion. Formula: Spend ÷ Conversions.
66. ROAS (Return On Ad Spend)
ROAS is the revenue generated for every rupee (or dollar) spent on ads. Formula: Revenue ÷ Ad Spend. A ROAS of 4 means ₹4 earned for every ₹1 spent. It is the most-asked metric in performance marketing interviews.
Quick Reference Table: Meta Ads Metrics Formulas
| Metric | Formula | What It Tells You |
|---|---|---|
| CPM | (Spend ÷ Impressions) × 1,000 | Cost of audience exposure |
| CPC | Spend ÷ Clicks | Cost of getting a click |
| CTR | (Clicks ÷ Impressions) × 100 | Ad creative effectiveness |
| Frequency | Impressions ÷ Reach | Risk of ad fatigue |
| CPL | Spend ÷ Leads | Lead generation efficiency |
| CPA | Spend ÷ Conversions | Cost to acquire one customer |
| ROAS | Revenue ÷ Ad Spend | Profitability of ad spend |
How These Terms Connect: The Meta Ads Hierarchy
One of the most common interview questions is: “Walk me through the structure of a Meta Ads campaign.” The correct answer follows this three-level hierarchy:
- Campaign Level — Choose the Campaign Objective and (optionally) set the Advantage Campaign Budget.
- Ad Set Level — Choose the Audience, Placements, Budget (if ABO), Schedule, Optimisation Event, and Attribution Setting.
- Ad Level — Upload the Ad Creative, Primary Text, Headline, Description, CTA, and Destination URL.
If you can confidently explain this hierarchy and name 2–3 metrics tracked at each level, you will already be ahead of most beginners.
Tips to Master These Terminologies Before Your Interview
- Open Meta Ads Manager and explore — even a free dummy account will show you Campaign, Ad Set, and Ad levels visually.
- Watch Meta Blueprint courses — Meta’s official free certification platform uses the exact same terminology recruiters use.
- Run a ₹500 test campaign — nothing teaches you CPM, CTR, and CPC faster than seeing them with your own spend.
- Practice formulas out loud — many interviews include a quick mental math question like, “If you spent ₹10,000 and got 25 leads, what’s the CPL?”
- Learn through structured training — a guided course shortens the learning curve. If you are based in Karnataka, our Mysore-based digital marketing course teaches Meta Ads with live campaign execution and interview preparation.
Frequently Asked Questions
What is the difference between Meta Ads and Facebook Ads?
Facebook Ads is the older name. Meta Ads is the current umbrella term that includes ads across Facebook, Instagram, Messenger, WhatsApp, and the Audience Network. In interviews, both terms are accepted but Meta Ads is the more current usage.
What are the three levels of a Meta Ads campaign?
The three levels are Campaign (where you choose the objective), Ad Set (where you define audience, budget, and placements), and Ad (where the creative, copy, and CTA live).
What is the most important metric on Meta Ads?
It depends on the campaign objective. For e-commerce brands, ROAS and Cost Per Purchase matter most. For service businesses, Cost Per Lead (CPL) is critical. For awareness campaigns, CPM and Reach are key. Always tie the metric to the objective.
What is the Meta Pixel and why is it important?
The Meta Pixel is a JavaScript snippet installed on your website that tracks user actions and sends them back to Meta. It enables conversion tracking, retargeting, and Lookalike Audience creation — all critical for performance advertising.
What is the Learning Phase in Meta Ads?
The Learning Phase is the initial period where Meta’s algorithm explores how to deliver your ad set. It typically requires 50 optimisation events within 7 days to exit. During this phase, performance is unstable and major changes should be avoided.
What is ROAS and how do you calculate it?
ROAS stands for Return On Ad Spend. It is calculated as Revenue divided by Ad Spend. For example, if you spent ₹10,000 and generated ₹40,000 in revenue, your ROAS is 4 — meaning you earned ₹4 for every ₹1 spent.
Are these 72 Meta Ads terms enough to crack an interview?
For beginner and junior performance marketing roles, yes — these 72 terminologies cover the core vocabulary recruiters test. For senior roles, you will also need hands-on experience, knowledge of Advantage+ Shopping Campaigns, and case studies of past campaigns you have run.
Final Word
Memorising these 72 Meta Ads interview terminologies is the first step. The real edge comes when you can apply them to live campaigns — diagnosing why CTR is low, deciding when to move from ABO to CBO, or explaining why a Lookalike outperforms a Core Audience.
