Your comprehensive guide to SEO, GEO, and Inbound Marketing terms
A 301 Redirect is an HTTP status code (301 Moved Permanently) that informs browsers and search engines that a web page's URL has permanently moved to a new address. It automatically directs users and search engine crawlers arriving at the old URL to the new URL, while transferring the link equity accumulated by the original page to the new URL.
A 302 Redirect is an HTTP status code (302 Found) that tells browsers and search engines a web page's URL has temporarily moved to a different address. It directs users and crawlers to the temporary URL while signaling that the original URL will be restored. As a result, search engines keep the original URL in their index and preserve its link equity rather than transferring it to the temporary destination.
A 307 Redirect is an HTTP status code (307 Temporary Redirect) that tells browsers and search engines a URL has temporarily moved to a different address. It is similar to a 302 redirect, but with one critical distinction: the original HTTP method (GET, POST, etc.) and request body must be preserved exactly when following the redirect.
A 308 Redirect is an HTTP status code (308 Permanent Redirect) that tells browsers and search engines a URL has permanently moved to a new address. Like a 301 redirect, it signals a permanent move, but with one critical distinction: the original HTTP method (GET, POST, etc.) and request body must be preserved exactly when following the redirect.
A 404 page is the HTTP status code (404 Not Found) returned by a server when the requested URL does not exist. When a browser or search engine crawler attempts to access a specific URL and the server cannot locate the corresponding page, it responds with a 404 status and informs the visitor that the page is unavailable.
A/B testing is an experimentation technique in which two versions (A and B) of a marketing asset—such as a web page, email, or ad—are simultaneously shown to comparable user groups under identical conditions. Key metrics like conversion rate and click-through rate are then compared to select the superior version based on data.
AEO (Answer Engine Optimization) is the practice of optimizing content so that it is selected as a direct answer by AI-powered search engines, voice assistants, and chatbots — collectively known as answer engines.
AI Crawling refers to the process by which automated bots operated by AI companies—such as GPTBot, ClaudeBot, and PerplexityBot—visit and collect content from websites. The collected data is used for a variety of purposes, including large language model (LLM) training, AI search result generation, and real-time question answering.
AI Overview is an AI-generated summary answer that Google displays at the very top of the search engine results page (SERP), powered by its Gemini model. When a user enters a search query, AI Overview synthesizes information from multiple web sources into a single summary response. Since its official launch in May 2024, it has been expanding rapidly.

Drop-off occurs at each stage, progressively reducing the pool of prospects—hence the funnel shape. Analyzing this structure reveals where the greatest drop-off happens.
Core Web Vitals are three key user experience metrics defined by Google that quantify a web page's loading speed, responsiveness, and visual stability.

An Internal Link is a hyperlink on one page of a website that points to another page on the same website (domain).
A keyword is a word or phrase that users enter into a search engine to find information. In SEO, keywords are the essential bridge connecting content to search users. Without a sound keyword strategy, ranking at the top of search results is virtually impossible.

A lead magnet is free content or a tool that a business offers in exchange for a prospect's contact information—email, name, phone number, and the like. Just as a magnet attracts metal, a lead magnet captures the attention of target customers to generate leads, making it a core device in inbound marketing.
Lead nurturing is the series of marketing activities in which prospects (leads) who have entered the marketing funnel receive tailored content and messages at the right time, building trust and ultimately driving them toward a purchase conversion.
Link building is the strategic process of acquiring hyperlinks (backlinks) from external websites to your own. Because search engines interpret backlinks as votes of confidence, systematically building quality links is a cornerstone of improving search rankings.
LLM Visibility refers to how frequently and in what context a specific brand is mentioned and recommended when LLM-based AI chatbots—such as ChatGPT, Gemini, Perplexity, and Claude—respond to user questions.
llms.txt is a markdown-formatted text file placed at a website's root path (`/llms.txt`) that serves as a guide to help large language models (LLMs) such as ChatGPT, Claude, and Gemini quickly and accurately understand the site's key content.
Local SEO is a search engine optimization strategy that helps businesses appear prominently in search results when users search for products or services in a specific geographic area.
A long-tail keyword is a compound search query typically consisting of three or more words that reflects a user's specific search intent. For example, while "running shoes" is a short-tail keyword, "best wide-fit men's running shoes" is a long-tail keyword.
Marketing automation refers to the technology and strategy of using software to automatically execute repetitive marketing activities—email sends, lead classification, social media publishing, campaign performance analysis, and more.
A Meta Description is the page summary text written in the HTML `<meta name="description">` tag. It is displayed below the title on search engine results pages (SERPs) and is a key SEO element that influences whether users click through to your page.
MOFU (Middle of Funnel) is the middle stage of the marketing funnel, representing the point at which prospects have recognized their problem and are actively comparing and evaluating various solutions.
Noindex is a robots meta directive that instructs search engines not to include a specific page in search results. It can be set via an HTML `<meta>` tag or an HTTP response header (`X-Robots-Tag`), preventing the page from appearing on search engine results pages (SERPs) such as Google and Bing.
Off-page SEO encompasses all optimization activities that take place outside of your website to build domain authority, increase trustworthiness, and improve search engine rankings.
On-page SEO refers to the practice of optimizing elements within a web page — content, HTML source code, and site architecture — to improve search engine rankings and attract relevant organic traffic.
Organic traffic is the traffic that reaches a website by clicking on unpaid, natural search results (SERP) from search engines such as Google, Bing, and Naver.
Page speed is the time it takes from when a user requests a URL to when the web page content is fully loaded and displayed. Google has used page speed as a ranking factor since 2010, and its importance has grown significantly since the introduction of Core Web Vitals in 2021.
A pillar page is a comprehensive hub content piece that covers a core topic in broad scope. It serves as the centerpiece of a topic cluster strategy, connected to cluster content covering related subtopics through internal links.

Technical SEO is the practice of optimizing a website's technical infrastructure so that search engines can efficiently crawl, understand, and index its pages.
A Title Tag is the page title written in the HTML `<title>` element. It is displayed as the clickable blue link text on search engine results pages (SERPs) and also appears in the browser tab — making it a critical SEO element.

Zero-click search refers to a search in which users obtain their desired answer directly on the search engine results page (SERP) without clicking through to any website. As SERP features such as AI Overviews, Featured Snippets, and Knowledge Panels instantly satisfy search intent, the phenomenon of zero website visits is becoming increasingly prevalent.
