Running Meta Ads in India without understanding the core terminology is like driving without knowing what the dashboard symbols mean. You can get somewhere, but you will miss critical signals along the way. This glossary covers 50 essential Meta Ads terms — from campaign structure basics to advanced metrics — with clear explanations written for Indian brand managers, founders, and marketing leads who want to speak the language of performance marketing fluently.
Campaign Structure Terms
1. Campaign
The top level of Meta Ads structure. You set the campaign objective here — Sales, Traffic, Leads, Awareness, etc. One campaign can contain multiple ad sets.
2. Ad Set
The middle level of structure where you define your audience, placement, budget, and schedule. Different ad sets within the same campaign can target different audiences.
3. Ad
The actual creative unit — image, video, carousel, or collection — that users see in their feed. Multiple ads can run within a single ad set for creative testing.
4. Campaign Budget Optimisation (CBO)
A setting that lets Meta automatically distribute your campaign budget across ad sets, shifting spend toward whichever ad set is performing best. Recommended for most campaigns over manually set ad set budgets.
5. Ad Set Budget Optimisation (ABO)
The alternative to CBO — you manually set a daily or lifetime budget for each individual ad set. Gives more control, but requires more active management.
6. Learning Phase
The period after a new campaign or significant edit when Meta’s algorithm is gathering data to optimise delivery. During this phase, results are unstable. An ad set exits learning after approximately 50 optimisation events (usually purchases or leads).
7. Learning Limited
A status shown when an ad set cannot exit the learning phase due to insufficient conversions — usually caused by too-small budgets or too-narrow audiences. A common problem in Indian accounts with fragmented budgets.
8. Advantage+ Shopping Campaign (ASC)
Meta’s automated shopping campaign format that uses AI to find the best audiences and placements with minimal manual input. Increasingly effective for D2C brands with strong product catalogues.
Audience Terms
9. Custom Audience
An audience built from your own data — website visitors, customer lists, video viewers, Instagram engagers, or past purchasers. Custom audiences are your warmest, highest-converting targeting option.
10. Lookalike Audience
An audience Meta creates by finding people who share characteristics with your custom audience source. A 1% lookalike of purchasers is typically the highest-performing prospecting audience once you have 500+ customers.
11. Broad Audience
Targeting with minimal restrictions — usually just age, gender, and country/state. At budgets above ₹1L/month, broad targeting often outperforms interest targeting because Meta has enough data and budget to find buyers autonomously.
12. Interest Targeting
Targeting users based on their declared interests, page likes, and behaviour on Facebook and Instagram. Less effective than lookalike or custom audiences but useful for new accounts with limited pixel data.
13. Retargeting Audience
A custom audience of people who have already interacted with your brand — visited your website, added to cart, or viewed your content. Retargeting audiences typically convert at 3–5X the rate of cold prospecting audiences.
14. Audience Overlap
The percentage of people who exist in multiple ad sets simultaneously. High overlap causes your own campaigns to compete against each other, raising CPMs. Keep overlap below 20–25% between prospecting ad sets.
15. Audience Size
The total number of people in your target audience. For prospecting in India, aim for 20–50 lakh (2–5 million) minimum to avoid rapid frequency buildup and CPM spikes.
Bidding and Cost Terms
16. CPM (Cost Per Mille)
Cost per 1,000 impressions. This is the price you pay to reach 1,000 people. Healthy CPM for Indian D2C: ₹80–₹200. Above ₹300 signals creative fatigue or audience saturation.
17. CPC (Cost Per Click)
Cost per click on your ad. Calculated as total spend ÷ total clicks. Benchmark varies widely by category — ₹3–₹15 is typical for Indian D2C categories.
18. CPP (Cost Per Purchase)
Total ad spend ÷ number of purchases attributed to the campaign. The most important metric for D2C brands running purchase-optimised campaigns.
19. CPL (Cost Per Lead)
Total ad spend ÷ number of leads generated. The primary metric for lead generation campaigns (clinics, real estate, education).
20. ROAS (Return on Ad Spend)
Revenue attributed to ads ÷ total ad spend. A ROAS of 3X means every ₹1 spent returned ₹3 in revenue. Note: platform-reported ROAS often overstates true performance due to attribution overlap.
21. Blended ROAS
Total revenue ÷ total paid ad spend across all channels. A more accurate performance measure than platform-reported ROAS, which double-counts conversions across Meta and Google.
22. Bid Strategy
How you tell Meta to bid in the auction. Options include Lowest Cost (automatic), Cost Cap (target a maximum cost per result), and Bid Cap (maximum bid per auction). Most Indian brands should start with Lowest Cost.
23. Cost Cap
A bid strategy that tells Meta to target a specific cost per result on average. Useful when you have a clear MACPP (Maximum Allowable Cost Per Purchase) and want to prevent Meta from overspending.
Creative and Delivery Terms
Creative and Delivery Terms
24. Creative Fatigue
When an ad’s performance degrades because the audience has seen it too many times. Indicated by rising frequency, declining CTR, and increasing CPM. The primary cause of performance decay in Indian Meta Ads accounts.
25. Frequency
The average number of times a person in your audience has seen your ad. Frequency above 3.0 per week typically indicates the onset of creative fatigue.
26. CTR (Click-Through Rate)
Clicks ÷ impressions, expressed as a percentage. A CTR of 1%+ is generally healthy for Indian feed ads. Below 0.5% suggests the creative is not resonating with the audience.

27. Hook Rate
The percentage of people who watch the first 3 seconds of a video ad after it starts playing. A strong hook rate (30%+) indicates your opening frame and first line are successfully stopping the scroll.
28. Thumbstop Rate
Similar to hook rate — measures how often people pause their scroll when they encounter your video. Higher thumbstop = more engaging opening creative concept.
29. UGC (User-Generated Content)
Ad creatives that look like they were filmed by real customers rather than a production team — often shot on phone, casual tone, authentic feel. UGC-style ads consistently outperform polished studio content for Indian D2C brands, typically at a 1.5–2X CTR advantage.
30. Dynamic Creative
A Meta feature that automatically combines multiple images, videos, headlines, and descriptions and serves the best-performing combinations to different users. Useful for rapid creative testing with limited assets.
31. Carousel Ad
An ad format with multiple scrollable cards, each with its own image, headline, and link. Effective for showcasing multiple products, telling a sequential story, or breaking down a single product’s benefits.
32. Collection Ad
A mobile-optimised ad format that opens into a full-screen Instant Experience when tapped. Ideal for D2C brands with a product catalogue — often used for fashion, home décor, and beauty.
Pixel and Tracking Terms
33. Meta Pixel
A piece of JavaScript code installed on your website that tracks user behaviour — page views, add to carts, checkout initiations, and purchases — and sends that data back to Meta for optimisation and audience building.
34. Conversion API (CAPI)
A server-side tracking solution that sends conversion data directly from your server to Meta, bypassing browser-based tracking restrictions from iOS 14+ and ad blockers. Essential for accurate attribution in 2026.
35. Events Manager
Meta’s dashboard for managing and verifying pixel events. Use this to confirm your Purchase, Add to Cart, and Initiate Checkout events are firing correctly on the right pages.
36. Standard Events
Predefined Meta pixel events with specific names that Meta’s algorithm understands — Purchase, AddToCart, InitiateCheckout, Lead, ViewContent, Search. Using standard events (rather than custom events) improves algorithm optimisation.
37. Attribution Window
The time period after a click or view during which Meta attributes a conversion to your ad. The default is 7-day click + 1-day view. Changing this affects reported ROAS — a longer window will show more conversions but may include purchases that would have happened anyway.
Campaign Objective and Optimisation Terms
38. Campaign Objective
The overarching goal you select when creating a campaign. Options include Sales, Leads, Traffic, Engagement, App Promotion, and Awareness. Your objective determines how Meta’s algorithm delivers your ads.
39. Optimisation Event
The specific action within your objective that Meta optimises for at the ad set level. For a Sales campaign, you choose whether to optimise for Purchase, Add to Cart, or Landing Page View.
40. Prospecting
Campaigns targeting cold audiences — people who have never interacted with your brand. Prospecting is the top of your funnel and the primary driver of new customer acquisition.
41. Retargeting
Campaigns targeting warm audiences — people who have already shown interest in your brand. Retargeting typically delivers 5–8X ROAS compared to 2–4X for cold prospecting.
42. Full-Funnel Strategy
Running separate campaigns for each stage of the customer journey — awareness (top of funnel), consideration/retargeting (middle of funnel), and purchase/retention (bottom of funnel).
Reporting and Analysis Terms
43. Ads Manager
Meta’s primary interface for creating, managing, and reporting on ad campaigns. All performance data — CPM, CTR, CPP, ROAS, frequency — is accessible here.
44. Quality Ranking
A metric in Ads Manager that indicates how your ad’s perceived quality compares to ads competing for the same audience. Below Average ranking means Meta is penalising your CPM due to low expected engagement.
45. Delivery
Whether your ad is actively running, in learning phase, learning limited, scheduled, or paused. Always check delivery status before concluding an ad is “not performing.”
46. Reach
The number of unique people who saw your ad at least once. Different from impressions, which counts total ad views including multiple views by the same person.
47. Impressions
The total number of times your ad was displayed, including multiple views by the same person. Impressions ÷ Reach = Frequency.
48. A/B Test (Split Test)
Meta’s built-in feature for testing one variable at a time — creative, audience, or placement — with statistical significance. Produces cleaner data than testing multiple variables simultaneously in standard ad sets.
49. Breakdown
Ads Manager’s feature for segmenting performance data by age, gender, placement, device, time of day, or region. Useful for identifying which audience segments or placements are driving the best results.
50. Meta Advantage+
Meta’s umbrella term for AI-powered automation features — Advantage+ Audience, Advantage+ Placements, Advantage+ Creative, and Advantage+ Shopping Campaigns. These features give Meta more control over targeting and delivery decisions, and in 2026 often outperform fully manual setups for established advertisers with strong pixel data.
