- AEO (Answer Engine Optimization)
- The practice of optimizing content to appear as a direct answer in AI-generated search results, voice assistants, and featured snippets. AEO focuses on question-based content, structured data, and concise authoritative answers.
- Bounce Rate
- The percentage of visitors who leave a website after viewing only one page. A high bounce rate may indicate poor content relevance, slow load times, or weak calls to action.
- CAC (Customer Acquisition Cost)
- The total cost of acquiring a new customer, including all marketing and sales expenses. Reducing CAC while maintaining lead quality is the primary goal of efficient marketing.
- Churn Rate
- The percentage of customers or subscribers who stop using a service during a given time period. For agencies and SaaS businesses, reducing churn is often more profitable than acquiring new customers.
- Content Marketing
- A marketing strategy focused on creating and distributing valuable, relevant content to attract and retain a target audience. Blog posts, videos, social media, and email newsletters are common content marketing channels.
- CPC (Cost Per Click)
- The amount an advertiser pays each time someone clicks on their ad. Used in Google Ads and social media advertising. Lower CPC with high conversion rates equals more profitable campaigns.
- CTR (Click-Through Rate)
- The percentage of people who click on a link, ad, or email after seeing it. CTR measures how effectively your headline, ad copy, or subject line drives action.
- A score (1-100) developed by Moz that predicts how well a website will rank in search engine results. Higher DA indicates stronger backlink profile and ranking potential. Google does not use DA directly, but it correlates with ranking ability.
- Drip Campaign
- An automated email sequence triggered by a specific action (signup, purchase, abandonment) that delivers pre-written messages on a timed schedule. Drip campaigns nurture leads and drive conversions without ongoing manual effort.
- GBP (Google Business Profile)
- A free Google tool that allows businesses to manage their online presence across Google Search and Maps. Optimizing your GBP is the single most important local SEO action for brick-and-mortar businesses.
- Impressions
- The number of times a piece of content, ad, or search result is displayed to users. Impressions measure visibility — clicks and conversions measure effectiveness.
- Indexing
- The process by which search engines discover, crawl, and store web pages in their database. A page must be indexed before it can appear in search results. Tools like Google Search Console and IndexNow help ensure pages are indexed quickly.
- Keyword Research
- The process of identifying the search terms your target audience uses to find products, services, or information. Effective keyword research targets terms with sufficient search volume and manageable competition.
- KPI (Key Performance Indicator)
- A measurable value that indicates how effectively a marketing campaign or business activity is achieving its objectives. Common marketing KPIs include traffic, conversion rate, CAC, and revenue.
- LTV (Lifetime Value)
- The total revenue expected from a single customer over the entire relationship. LTV must exceed CAC for a business to be sustainable. Higher LTV justifies higher acquisition spending.
- MRR (Monthly Recurring Revenue)
- Predictable monthly income from subscriptions, retainers, or ongoing service agreements. MRR is the primary financial metric for agencies and SaaS businesses because it enables forecasting and valuation.
- Organic Traffic
- Visitors who arrive at a website through unpaid search engine results. Organic traffic is free, compounds over time, and is the highest-ROI traffic source for most small businesses.
- Programmatic SEO
- A strategy that uses templates and data to automatically generate large numbers of optimized pages targeting long-tail keywords. Common in directories, comparison sites, and location-based businesses.
- Retainer
- A recurring monthly fee paid to an agency or freelancer for ongoing services. Retainers provide predictable revenue for the provider and consistent marketing execution for the client. Typical small business agency retainers range from $1,500 to $5,000/month.
- ROAS (Return on Ad Spend)
- The revenue generated for every dollar spent on advertising. A ROAS of 4:1 means $4 in revenue for every $1 in ad spend. ROAS is the primary metric for evaluating paid advertising effectiveness.
- Schema Markup (Structured Data)
- Code added to a website that helps search engines understand the content and display rich results (star ratings, FAQs, how-to steps, product prices). Schema.org vocabulary is the standard used by Google, Bing, and Yahoo.
- SEM (Search Engine Marketing)
- The practice of using paid advertising to appear in search engine results. SEM typically refers to Google Ads (formerly Google AdWords) and Bing Ads. Unlike SEO, SEM delivers immediate visibility but requires ongoing ad spend.
- SEO (Search Engine Optimization)
- The practice of optimizing a website's content, structure, and technical elements to rank higher in organic (unpaid) search results. SEO is the foundation of the $20 agency model because it generates compounding free traffic.
- SERP (Search Engine Results Page)
- The page displayed by a search engine in response to a query. Modern SERPs include organic listings, paid ads, featured snippets, knowledge panels, local packs, and AI-generated answers.
- The degree to which a website is recognized by search engines as an expert source on a specific subject. Building topical authority requires comprehensive coverage of a topic through interlinked, high-quality content.
- White-Label
- A product or service produced by one company and rebranded by another to appear as their own. White-label SEO, content, and web design services allow small agencies to offer capabilities they don't have in-house.
