Digital marketing glossary

Clear explanations of SEO, AI search, content, advertising and analytics, with practical context.

323 terms

SEO

Search Intent

Search intent refers to the information the user seeks to obtain or the purpose he or she seeks to achieve through the search.

SEO

Keyword

Keywords are words or phrases that describe the search topic or what customers are looking for.

SEO

Long-tail Keyword

Long-tail keywords refer to various search terms in the search demand distribution with relatively low individual search volumes. The distinction is not based solely on word count; search intent, competition, and conversion potential must be checked in the context of individual search terms.

SEO

Short-tail Keyword

Short-tail keywords are keywords with few words and a wide scope, resulting in a high search volume. Because multiple intents are mixed and competition is high, it is effective to treat them as the upper topic of a hub page or topic cluster, and separate the lower intents into long-tail documents.

SEO

Branded Keyword

Branded keywords contain a company, brand, product or service name. They may express purchase, comparison, support or dissatisfaction; a brand name does not imply one uniform conversion intent.

SEO

Keyword Difficulty

Keyword difficulty is a tool’s estimate of search competition. Methods and scales differ, so fixed thresholds cannot be carried across tools as universal ranking criteria.

SEO

Search Volume

Search volume counts or estimates searches under selected time and location settings. It is not a visitor or purchase count, and is only one input to content priorities.

SEO

Keyword Gap

Keyword gap analysis compares the search-query profiles of competitor and owned domains. A tool’s gaps are a starting point for investigation, not an instruction to create an article for every term.

SEO

Keyword Cluster

Keyword clusters are groups of related keywords grouped together by the same topic or search intent and are the basic unit of SEO strategy for designing content so that a single page covers multiple related queries.

SEO

Topic Cluster

A topic cluster is a content structure that connects a hub page of a central topic and sub-documents dealing with detailed topics through internal links. It is a representative way to build topic authority and implement semantic SEO.

SEO

Cluster Content

Cluster content is a bundle of content that each explains detailed questions related to a central topic and links related documents.

SEO

Content Hub

A content hub connects a topic overview with detailed explanations through relevant links. It helps navigation; it is not a formula requiring a minimum article count or guaranteeing timed SEO results.

SEO

Content Gap

A content gap is the gap between what your customers need to know and what your site currently explains.

SEO

Helpful Content

Helpful content enables readers to answer a question or make a decision. Since March 2024, Google has assessed helpfulness through multiple core ranking systems, without a public single score or site-wide percentage.

SEO

Expertise

Expertise is an E-E-A-T component that refers to the expert knowledge and capabilities of a content creator or site on a specific topic.

SEO

Experience

Experience is an element in E-E-A-T that indicates whether the content is based on direct experience such as actual use, practical work, or visits. This is especially important in reviews, cases, and tutorials, where concrete context and limitations signal experience rather than abstract explanations.

SEO

Authoritativeness

Authoritativeness is an E-E-A-T component that refers to how strongly the content, author, or site is recognized as a source of authority on a specific topic or field.

SEO

Trustworthiness

Trustworthiness is an E-E-A-T component that indicates whether the content, site, author, and operator can be trusted.

SEO

E-E-A-T

E-E-A-T stands for experience, expertise, authoritativeness, and trustworthiness, and is a concept used when looking at content quality in the Google Search Quality Evaluation Guide.

SEO

Meta Description

A meta description is HTML meta information that summarizes the content of a web page. Search engines can use this as a reference when creating snippets of results, but they won't always display exactly what you type.

SEO

H1 Tag

The H1 tag is the representative title of the page body and serves to identify the topic as soon as the user arrives. It must be semantically consistent with the title tag, and one per page is generally recommended.

SEO

H2 Tag

An H2 is a second-level HTML heading. It identifies a major section and aids navigation; using it does not guarantee a featured snippet or a ranking improvement.

SEO

Anchor Text

Anchor text is the visible wording of a link. Describe the destination accurately in context; keyword percentages and repetition counts are not a formula for results.

SEO

Internal Link

Internal links are links that connect other pages within the same domain. It is a core structural element of SEO that helps crawlers navigate your site, distributes link authority (link juice) between pages, and guides visitors to explore related content.
