Ad Account Glossary
Clear definitions for the terms that matter most in paid advertising — from agency accounts and attribution to pixels, ROAS, and suspensions.
A
Agency Ad Account
An advertising account provisioned directly through a platform-certified agency partner rather than created self-serve by an individual advertiser. Agency accounts come with higher spend limits, dedicated policy escalation channels, and risk isolation structures that prevent a violation on one account from affecting others in the same portfolio. They are the standard infrastructure choice for agencies and performance marketing teams spending at scale on Meta, TikTok, or Google Ads. AdsInfra provisions and manages agency accounts for enterprise advertisers on a 2% flat-fee model.
Appeal (Ad Account)
The formal process by which an advertiser contests a platform's decision to disable, restrict, or suspend their ad account or individual ads. Each platform — Meta, TikTok, Google — provides a dedicated appeal workflow, typically accessible from the Account Quality dashboard or a suspension notification. A successful appeal requires clear documentation of your business, an explanation of why the enforcement was in error, and often supporting evidence like business registration or landing page screenshots. See the platform-specific appeal guides in our Survival Center.
Attribution Window
The time period after an ad click or view during which a conversion is credited to that ad. Common windows are 1-day click, 7-day click, and 1-day view. Longer windows capture more conversions but can overcount by attributing purchases that would have happened organically. Meta's default shifted to a 7-day click, 1-day view window in 2021, and changes to iOS privacy controls have made attribution less deterministic — conversion API (CAPI) integrations are now essential for accurate measurement. Comparing ROAS across accounts requires confirming the attribution window is consistent.
B
Bid Cap
A manual bidding strategy in which the advertiser sets a hard ceiling on how much the platform's algorithm can bid in any given auction. Bid caps give advertisers cost control but can limit delivery if the cap is set below the clearing price for your target audience. They are commonly used in lead generation and direct-response campaigns where profitability above a specific CPA must be guaranteed. Contrast with cost cap, which targets an average cost rather than a per-auction maximum.
Business Manager (Meta)
Meta's centralized platform for managing ad accounts, Pages, pixels, catalogs, and team permissions. A single Business Manager can contain multiple ad accounts, making it both a productivity tool and a risk management layer — policy violations in one account can affect the entire Business Manager if not properly isolated. Business Verification in Business Manager unlocks higher ad spend limits and adds legitimacy to your account structure. See our Meta platform guide for best practices.
C
Campaign Budget Optimization (CBO)
A Meta Ads feature (now called Advantage Campaign Budget) that shifts budget allocation decisions from the ad set level to the campaign level, allowing Meta's algorithm to dynamically distribute spend across ad sets based on real-time performance signals. CBO tends to perform better with larger total budgets and diverse creative sets, as the algorithm has more room to optimize. It can be problematic for campaigns that require guaranteed minimum spend on specific ad sets, in which case ad set budget control is preferable.
Click-Through Rate (CTR)
The percentage of ad impressions that result in a click, calculated as (clicks ÷ impressions) × 100. CTR is a primary measure of creative and audience relevance — a high CTR indicates your ad is resonating with the audience being targeted. Industry average CTRs vary significantly by platform and format: Meta news feed CTR benchmarks hover around 0.9–1.5%, while TikTok In-Feed Ads typically see 0.5–1.0%. CTR is most useful as a comparative metric within your own account history rather than as an absolute benchmark.
Conversion API (CAPI)
A server-side event tracking integration that sends conversion data directly from your server to a platform's API, bypassing browser-based limitations introduced by iOS privacy changes and ad blockers. Meta's CAPI, TikTok's Events API, and Google's Enhanced Conversions all work on this principle. CAPI significantly improves event match quality and attribution accuracy. For Meta in particular, running browser pixel and CAPI in parallel (with deduplication) is the current best practice for maximizing reported conversion volume and improving algorithmic optimization.
Conversion Rate
The percentage of ad clicks (or landing page visitors) that complete a desired action, such as a purchase, form submission, or sign-up. Calculated as (conversions ÷ clicks) × 100. Conversion rate benchmarks differ substantially by industry, funnel stage, and offer type. A 2–5% e-commerce conversion rate from paid traffic is generally considered healthy, while high-ticket B2B offers may see 0.5–1.5% from cold traffic but much higher from retargeting. Conversion rate optimization (CRO) on the landing page side often delivers more incremental revenue than additional ad spend.
CPM (Cost Per Mille)
The cost per 1,000 ad impressions, used as the standard pricing unit in display, video, and social advertising auctions. CPM is determined by auction dynamics — demand for a given audience at a given time of day — and varies by platform, placement, season, and vertical. Q4 CPMs on Meta routinely run 30–50% higher than Q1 due to holiday advertiser competition. Understanding CPM alongside CTR and conversion rate allows media buyers to model the full cost-to-acquisition funnel and identify where efficiency gains are available.
Creative Fatigue
The decline in ad performance that occurs when an audience has seen the same creative too many times. Symptoms include rising CPM and CPCs, declining CTR, and dropping ROAS — all while the account's targeting and bid strategy remain unchanged. Meta's Frequency metric (average number of times a user saw your ad) is the primary indicator; frequency above 3–4 within a week typically signals fatigue for cold audiences. The remedy is refreshing creative — new hooks, different formats, or updated offers — rather than adjusting bids or budgets.
Custom Audience
An audience built from your own first-party data — customer email lists, website visitors tracked by a pixel, app activity, or video viewers — used for retargeting or exclusions in Meta, TikTok, and Google campaigns. Custom audiences are among the highest-converting segments in any paid social account because they target people who have already expressed intent. They are also at risk when an ad account is suspended, because pixel data and custom audiences are tied to specific Business Managers and may not be easily portable.
D
Delivery (Ad Delivery)
The status of whether an ad, ad set, or campaign is actively serving impressions. 'Active' delivery means the ad is in auction and winning impressions; 'limited' delivery usually indicates a budget, bid, audience size, or policy issue constraining reach. Platforms show delivery status at each level of the campaign hierarchy. TikTok Ads Manager provides hover-over delivery reason codes that are particularly useful for diagnosing zero-delivery situations. Delivery issues are among the most searched problems by media buyers — see our TikTok delivery guide.
Disapproval (Ad Disapproval)
A platform's rejection of a specific ad, citing a policy violation in the creative, copy, or destination URL. Disapprovals are ad-level actions and do not immediately suspend an account, but a high disapproval rate — especially for policy categories like circumventing systems or misrepresentation — can trigger account-level review. Each platform provides a reason code with the disapproval; addressing the root cause (fixing the ad or the landing page) and resubmitting is the standard resolution path. Repeated disapprovals for the same policy signal that a deeper review of your creative strategy is needed.
Dynamic Creative
A campaign format where the platform automatically tests combinations of creative assets — headlines, images or videos, descriptions, CTAs — and identifies the best-performing combination for each user. Meta's Dynamic Creative and Google's Responsive Search Ads are the most widely used implementations. Dynamic creative is effective for finding winning combinations faster than manual A/B testing, but it reduces creative control and makes attribution of performance to specific elements more difficult. It works best with at least 3–5 variations of each asset component.
E
Event Match Quality
Meta's score (rated Low, Medium, or High) for how well the customer information sent with a conversion event matches Meta's user database. Higher event match quality means better attribution — Meta can more accurately tie a conversion to the ad that drove it. To improve EMQ, send as many hashed customer data parameters as possible with each event: email, phone number, first and last name, city, state, zip, and country. Conversion API integrations typically achieve higher EMQ than browser-only pixel implementations because server-side requests bypass ad blockers and iOS restrictions.
F
Frequency
The average number of times a unique user has seen your ad within a given time period. Frequency is calculated as impressions ÷ reach. High frequency (above 3–4 per week for cold audiences) indicates creative fatigue and can lead to negative user sentiment — Meta tracks 'hide ad' and 'report ad' actions that can negatively affect your account's delivery. Controlling frequency is most important in small retargeting audiences where the same users are cycling through your ads repeatedly. Expanding audience size or refreshing creative are the primary levers.
G
GCLID
Google Click Identifier — a unique parameter automatically appended to the destination URL when a user clicks a Google Ad. GCLIDs enable Google Ads to track which specific click led to a conversion and are essential for accurate attribution in Google Analytics and offline conversion imports. If your URL parameters are being stripped by your website, redirect, or CRM, GCLID-based conversion tracking will break silently — your reported conversions in Google Ads will drop while actual sales remain unchanged. Always verify GCLID passthrough is intact when changing your website infrastructure.
L
Lookalike Audience
A targeting option that instructs the platform to find users who are statistically similar to a source audience — typically your existing customers or highest-value website visitors. Meta Lookalikes (1–10% similarity range) and TikTok Lookalikes work by analyzing the behavioral and demographic signals of your source audience and matching them against the broader user base. The quality of a lookalike is directly dependent on the quality and size of the source audience; a purchase-based lookalike seeded with 1,000+ conversions typically outperforms one seeded with only 100 website visits.
M
MCC (Manager Account)
Google's Manager Account (formerly called My Client Center or MCC) is a top-level account structure for managing multiple Google Ads accounts under one login. MCCs allow consolidated billing, bulk management, and shared access controls across client accounts. Agency accounts operated through AdsInfra use an MCC structure that provides billing trust signals to Google, which correlates with smoother account approvals and fewer payment-related friction events. Advertisers benefit from being under a well-established MCC without needing to build that history themselves.
Meta Business Suite
Meta's unified management interface for Facebook Pages, Instagram accounts, ad accounts, and business assets, replacing the older Ads Manager and Page Manager tools. Business Suite consolidates inbox management, content scheduling, analytics, and advertising controls in one place. It is distinct from Business Manager (the administrative account structure) — Business Suite is the interface while Business Manager is the underlying account architecture. Confusion between the two often leads advertisers to look for settings in the wrong place when troubleshooting policy or access issues.
P
Pixel (Meta Pixel)
A JavaScript code snippet placed on your website that fires events — page views, add to cart, initiate checkout, purchase — and sends them to Meta for use in conversion tracking, retargeting audience building, and campaign optimization. The pixel is tied to a specific Business Manager and ad account, which means losing access to your ad account can restrict your ability to use pixel-driven audiences in new campaigns. Running the Conversion API alongside the browser pixel is now considered essential for maintaining data quality as iOS privacy changes continue to reduce browser-based event capture.
Policy Violation
A breach of a platform's advertising policies, which can result in individual ad disapproval, ad account restriction, or full account suspension depending on severity and recurrence. Common violations include promoting prohibited content categories, using deceptive or misleading claims, directing traffic to non-compliant landing pages, or attempting to circumvent platform review systems. Each platform publishes detailed policy documentation, and violations can sometimes be triggered by automated systems flagging legitimate ads in error — making the appeal process an important skill for any active media buyer.
R
ROAS (Return on Ad Spend)
Revenue generated divided by ad spend, expressed as a multiple (e.g., 3× ROAS means $3 in revenue for every $1 spent on ads). ROAS is the primary performance metric for e-commerce and direct-response advertisers. What constitutes a 'good' ROAS depends entirely on your margins — a business with 70% gross margins can be profitable at 2× ROAS while a business with 30% margins may need 5× just to break even. Platform-reported ROAS is also increasingly unreliable due to attribution windows and iOS-driven signal loss; triangulating with third-party attribution tools is standard practice at scale.
Remarketing
Advertising directed at users who have previously interacted with your brand — visited your website, viewed a product page, added to cart, watched a video, or engaged with your social content. Remarketing audiences consistently outperform cold audiences on conversion rate because they target people already familiar with your brand and offer. The most valuable remarketing segments are usually abandoned carts and product page viewers in the last 7–14 days. Effective remarketing requires a functioning pixel or events API and audiences large enough to be statistically significant for algorithmic optimization.
Restricted Account
An ad account that has had specific capabilities removed or capped by a platform without being fully disabled. On Meta, restrictions can include reduced daily spend limits, inability to advertise in certain categories, or mandatory Business Verification before campaigns can continue. On Google, restrictions may apply to specific ad formats or destination domains. Restrictions are generally less severe than full suspensions and often resolvable through verification steps or appeals. Our Meta restricted account guide details the specific restriction types and resolution paths.
S
Spend Limit
A cap on how much can be spent in a given period — set either by the platform at an account level or by the advertiser as a control mechanism. Platform-imposed spend limits are common on new accounts and accounts with limited billing history; they increase automatically as an account establishes a positive payment track record. Advertiser-set account spending limits in Meta, for example, prevent total account spend from exceeding a set amount — useful for budget control but easy to forget, which can cause campaigns to stop mid-month. Agency accounts through AdsInfra typically have significantly higher platform-imposed spend limits than new self-serve accounts.
Suspended Account
An ad account that has been fully disabled by a platform, preventing all campaigns from delivering. Suspensions differ from restrictions in that no advertising activity is possible until the suspension is lifted. Causes range from payment failure (billing suspensions, usually resolvable quickly) to policy violations (may require appeal and documentation) to fraud detection triggers. The appeal process, required documentation, and expected timelines vary by platform. See our platform-specific suspension guides: Meta, TikTok, Google.
T
TikTok Ads Manager
TikTok's self-serve advertising platform where campaigns, ad groups, and individual ads are created, managed, and analyzed. TikTok Ads Manager uses a three-tier structure: Campaign (objective and budget) > Ad Group (targeting, placement, bid, schedule) > Ad (creative). The platform has its own policy review system and delivery algorithm. Unlike Meta, TikTok currently has less granular audience data available for targeting, placing greater weight on creative quality as the primary performance lever. An ad account in TikTok Ads Manager lives within a TikTok Business Center.
TikTok Business Center
TikTok's equivalent of Meta Business Manager — the administrative layer for managing ad accounts, users, assets (pixels, catalogs, events), and billing. A Business Center must be verified to unlock the highest spend tiers and to qualify for agency-level support channels. AdsInfra operates accounts within a verified Business Center, which provides advertiser clients with full operator-level access to their campaigns without requiring them to set up and verify their own Business Center from scratch. This significantly reduces the onboarding timeline for new advertisers.
V
Value-Based Bidding
A bidding strategy that instructs the platform's algorithm to optimize for conversion value rather than conversion volume — bidding more aggressively for high-value customers and less for lower-value ones. Meta's Value Optimization and Google's Target ROAS are the primary implementations. Value-based bidding requires passing purchase value data with each conversion event (via pixel or CAPI) and enough historical conversion data (typically 50+ purchases in the last 7 days) for the algorithm to train on. When it works, it improves ROAS without reducing volume, but it requires clean value data and sufficient conversion history.
Verification (Business Verification)
A process by which Meta, TikTok, or Google confirms that an advertiser is a legitimate registered business. On Meta, Business Verification involves submitting documents (business registration, tax ID, utility bills) through the Security Center in Business Manager. Verified businesses unlock higher ad spend limits, access to restricted advertising categories, and reduced risk of algorithmic enforcement flags. Verification is not the same as identity verification (which confirms an individual's identity) — both may be required for full account functionality on Meta. Completing both is a critical step for any advertiser planning to scale.
Don't let terminology hold you back
Understanding the terms is step one. Step two is getting the infrastructure that lets you apply them at scale — without the risk of losing your account mid-campaign.
