Performance Marketing Glossary
Understand the most important terms and metrics used in performance marketing, Meta Ads, and Google Ads.
ROAS (Return on Ad Spend)
ROAS measures the amount of revenue your business earns for every rupee spent on advertising. For example, if you spend ₹1,000 on Meta Ads and generate ₹5,000 in sales, your ROAS is 5x. It's the most important metric for determining the profitability of performance marketing campaigns. A high ROAS indicates your targeting and creatives are working effectively.
Learn more about this serviceCPL (Cost Per Lead)
Cost Per Lead is the total ad spend divided by the number of new leads generated. It tells you exactly how much it costs to acquire a potential customer's contact information. Tracking CPL helps you determine if your ad budget is being spent efficiently. A low CPL is good, but lead quality is equally important for final conversion.
Learn more about this serviceCPM (Cost Per Mille / Thousand Impressions)
CPM is the cost an advertiser pays for one thousand views or impressions of an advertisement. It's a key metric for understanding the competitiveness of the audience you are targeting on platforms like Meta or Google. If your CPM is very high, it might indicate high competition or that your audience is too narrow.
Learn more about this serviceCTR (Click-Through Rate)
Click-Through Rate is the percentage of people who click on your ad after seeing it. It's calculated by dividing total clicks by total impressions. A high CTR indicates that your ad creative and copy are highly relevant and engaging to the audience. Improving your CTR usually lowers your Cost Per Click (CPC).
Learn more about this serviceCPA (Cost Per Acquisition / Action)
Cost Per Acquisition measures the aggregate cost to acquire one paying customer on a campaign or channel level. Unlike CPL, which measures the cost of a potential lead, CPA tracks the cost of the final desired action, usually a purchase or a closed deal. This metric directly impacts your profitability.
Learn more about this serviceCAC (Customer Acquisition Cost)
Customer Acquisition Cost encompasses all costs related to acquiring a new customer, including marketing spend, software costs, and team salaries. While CPA usually refers to a specific campaign's cost, CAC is a broader business metric. Comparing your CAC to the Customer Lifetime Value (LTV) is crucial for sustainable business growth.
Learn more about this serviceLookalike Audience
A Lookalike Audience is a targeting option on Meta Ads that finds new people who share demographics and behaviors with your existing best customers. You create a 'seed' audience (e.g., past purchasers or website visitors), and the algorithm finds similar users. It's one of the most powerful tools for scaling campaigns to new, high-intent prospects.
Learn more about this serviceCustom Audience
A Custom Audience allows you to target users who have already interacted with your business. This could be people who visited your website, engaged with your Instagram page, or exist in your CRM database. Custom Audiences are primarily used for retargeting campaigns to convert warm prospects into buyers.
Learn more about this serviceConversions API (CAPI)
The Meta Conversions API creates a direct, server-to-server connection between your website's server and Meta. It passes web events (like purchases or leads) directly to Meta, bypassing the browser. This is essential for accurate tracking and optimization, especially after privacy updates like iOS 14 that limit browser-based pixel tracking.
Learn more about this serviceMeta Pixel
The Meta Pixel is a piece of code placed on your website that tracks visitor activity. It allows you to measure the effectiveness of your advertising by understanding the actions people take on your site. The Pixel is critical for building Custom Audiences, tracking conversions, and optimizing ad delivery.
Learn more about this serviceQuality Score
Quality Score is Google Ads' rating of the quality and relevance of your keywords, ads, and landing pages. A higher Quality Score can lead to lower prices and better ad positions. It is determined by your expected click-through rate, ad relevance, and the user experience on your landing page.
Learn more about this serviceCore Web Vitals
Core Web Vitals are a set of specific factors that Google considers important in a webpage's overall user experience. They consist of Largest Contentful Paint (LCP), First Input Delay (FID)/Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS). Optimizing these metrics is crucial for technical SEO and high conversion rates.
Learn more about this serviceLanding Page
A landing page is a standalone web page created specifically for a marketing or advertising campaign. It's where a visitor 'lands' after clicking an ad. Unlike a standard homepage, a landing page has a single focus or call to action (CTA), making it much more effective at converting traffic into leads.
Learn more about this serviceRetargeting
Retargeting (or remarketing) is a strategy of serving ads to people who have previously visited your website or engaged with your brand but did not convert. Since these users are already familiar with your business, retargeting campaigns typically have higher conversion rates and lower costs compared to prospecting campaigns.
