SEO fundamentals glossary

Understanding SEO fundamentals in a business context

SEO fundamentals are the basic ideas used to describe search demand, search results, and page optimization. The vocabulary is useful when it helps you choose a next action. A higher ranking or a more attractive search result matters to a service business when the visitor can find a relevant service and contact the team.

Using these definitions in your workflow

Begin with the page’s intended customer and the problem it answers. Compare the searcher’s wording with the page title, main heading, and visible explanation. Inspect the actual result format before assuming that a standard page is the right answer. Keep definitional queries separate from service-buying queries when assigning page ownership.

A roofer’s repair page and a roof-maintenance explanation can serve different readers. Writing both makes sense when each has its own job. Repeating a keyword across many similar pages does not establish that those jobs differ. Use the terms here to explain the distinction in your page plan.

Checking the evidence behind a report

Read the search result format as evidence of the question people are asking. A term can appear in a service query and in an informational query while requiring different page content. Match the visible title and heading to the page’s actual purpose.

A glossary definition should explain vocabulary rather than promise to supply the service itself. When a report compares competing URLs, inspect what each page offers before labeling the overlap a problem. Similar keywords are not enough to establish that two pages answer the same need.

For practical context, use the matching website tool and compare the task with our service scope. Return to the full SEO glossary when the report uses terms from another topic.

Terms in this topic

Each entry below introduces a distinct concept. Open its explanation for the practical procedure and cautions. These definitions describe terminology, not a ranking guarantee. Check the original documentation when a report’s wording or a platform feature changes.

• Organic traffic

  Organic traffic is website traffic attributed to unpaid search results. A visit is a channel observation, not proof that the visitor became a qualified lead.

• SERP

  A SERP is a search engine results page. Its links, map listings, and other features change with the query and the searcher's context.

• Search volume

  Search volume is an estimate of how often people search a keyword during a stated period in a defined market. It is not a forecast of website visits.

• Keyword cannibalization

  Keyword cannibalization is a situation where several pages compete for the same search intent without a clear reason for each page to exist.

• Keyword stuffing

  Keyword stuffing is the excessive or unnatural use of search terms to manipulate rankings. Google's spam policies cover repetition that makes content less useful.

• Keyword gap

  A keyword gap is a difference between the queries covered by your website and those covered by competing sites. Each gap still needs a business and intent check.

• White hat SEO

  White hat SEO is an industry term for optimization that follows search engine policies and helps people use a website. It is not a Google certification.

• Black hat SEO

  Black hat SEO is an industry term for tactics that violate search engine policies to manipulate visibility. Examples include cloaking and paid links created to influence rankings.

• Negative SEO

  Negative SEO is an attempt to harm another website's search visibility. A suspicious link or a traffic decline alone does not establish that an attack occurred.

• YMYL

  YMYL means Your Money or Your Life. Google uses the concept for subjects where unreliable information can significantly affect people's health, financial stability, safety, or wider well-being.

• Helpful content

  Helpful content is content created to meet a reader's needs rather than primarily to attract search engine traffic. Google emphasizes usefulness, reliability, and people-first intent.

• Title tag

  A title tag is the HTML title element that names a web page. Search engines can use it when creating a result's title link, but may display different wording.

• H1 tag

  An H1 tag is a top-level HTML heading that identifies a page's main subject. It serves the visible document structure and is different from the HTML title element.

• Alt text

  Alt text is a text alternative for an image. It communicates an image's relevant meaning when someone cannot see it, and helps search engines understand image context.

• URL slug

  A URL slug is the readable path segment used to identify a page. A clear slug helps people understand a destination before they open it.

• People Also Ask

  People Also Ask is a Google results feature that presents related questions with expandable answers. Its presence and questions depend on the search and can change.

• Knowledge panel

  A knowledge panel is a Google Search information box about an entity such as a person or organization. It is different from a Google Business Profile listing.

• Rich results

  Rich results are search appearances with supported features beyond a standard text link. Eligible structured data can help a page qualify, but does not guarantee a feature.

• Cloaking

  Cloaking is presenting different content to search engines and people with the intent to manipulate search results. Google identifies cloaking as a spam practice.

• SERP features

  SERP features are result formats beyond conventional text listings, such as image results, featured snippets, and map results. Their availability depends on the query and search engine.

• Keyword mapping

  Keyword mapping is assigning related search queries and their intent to specific website pages. The purpose is to give each page a clear role in the search journey.

• Meta description

  A meta description is an HTML summary of a page. Google may use it for a search snippet or choose text from the page that better matches a query.

• Featured snippet

  A featured snippet is an excerpt Google selects from a web page to answer a search query. Site owners cannot mark a page as a featured snippet themselves.

• Grey hat SEO

  Grey hat SEO is an informal label for tactics described as lying between policy-compliant optimization and manipulation. The label does not exempt a tactic from Google's spam policies.

• Share of voice

  Share of voice is a comparison of a brand's visibility against a defined competitor set. In SEO, the result depends on the chosen keywords, market, and measurement method.
