Terms 685 / 685
RWD (Responsive Web Design)
Designing layouts that adapt to available screen space through flexible structures, images and CSS media queries. Responsiveness supports usability but does not by itself establish full accessibility.
Definition and sourcesSaaS (Software as a Service)
Software delivered as a provider-managed service. Customers use the application while the provider maintains its environment. Subscriptions or licences may apply; SaaS does not eliminate costs or every customer responsibility.
Definition and sourcesSales funnel
A model of stages from initial contact to purchase and an ongoing relationship. It supports diagnosis, though real journeys can revisit earlier stages.
Definition and sourcesSatoshi Nakamoto
The pseudonym of Bitcoin's author or authors and its white-paper author. The identity has not been publicly established. Speculation alone should not be presented as identifying a particular person.
Definition and sourcesScalable Vector Graphics
An XML-based vector-graphics format. Scaling preserves geometry; untrusted SVG requires sanitisation because it can contain active elements.
Definition and sourcesSchema
A description of data organisation and relationships. In SEO, the name often refers to Schema.org, a vocabulary of structured-data types and properties. These are different meanings; correct markup does not guarantee enhanced search results.
Definition and sourcesScreaming Frog SEO Spider
A crawler analysing technical site elements such as responses, links and metadata. Reports identify issues to assess but do not alone diagnose every traffic loss.
Definition and sourcesScrum
A framework for complex problems using transparency, inspection and adaptation. A Scrum Team includes a Product Owner, Scrum Master and Developers. A Sprint lasts no more than one month. Scrum is not a success guarantee or complete project recipe.
Definition and sourcesSCSS
A Sass syntax largely compatible with CSS notation. It compiles into CSS; browsers do not directly execute SCSS source.
Definition and sourcesSearch engine reputation management
Activities concerning how a brand or person appears in search results. They should rely on accurate information rather than fabricated reviews.
Definition and sourcesSearch engine results page
A search-results page containing links, ads and additional modules. Layout varies by query, device, market and experiments.
Definition and sourcesSearch Generative Experience
A historical name for Google's experimental generative search experience. Earlier tests should not be equated with current AI Overviews availability in every country.

Analysing and storing page information in a search index. Crawling does not guarantee indexing, and indexing does not guarantee visibility for a particular query.
Definition and sourcesSearch intent
The goal behind a query, such as learning, comparison or purchasing. It is inferred from context; one phrase may express several intents.
Definition and sourcesSearch optimisation
Work to make pages easier to discover in unpaid search results, including content, structure and technical accessibility. It is not buying rankings and does not guarantee a position or a delivery date for results.
Definition and sourcesSegmentation
Dividing audiences into groups using useful criteria such as needs or behaviour. Segments should improve decisions rather than merely complicate reporting.
Definition and sourcesSEM (Search Engine Marketing)
Marketing through search engines. Usage can be broad, including SEO, or narrower, meaning paid search advertising. Agree scope in the brief. Buying an ad does not purchase an organic ranking.
Definition and sourcesSender Policy Framework
A DNS policy authorising sending sources for the envelope-sender domain. It neither signs content nor alone authenticates the visible From field.
Definition and sourcesSEO (Search Engine Optimization)
Making useful content easier for search engines to discover, understand and present, including technical correctness. SEO supports organic visibility but does not guarantee rankings or traffic.
Definition and sourcesSEO site network
A network of sites used to support another site's promotion. If primarily intended for link manipulation, it can violate policies regardless of visual quality.
Definition and sourcesServer
A program or system providing services to clients, such as HTTP responses or database access. The word also commonly describes its host machine. Servers can operate within local networks without internet access.
Definition and sourcesServer logs
Records of server events, requests and errors. They support diagnosis and auditing and need access controls, retention rules and limited secret recording.
Definition and sourcesServer Name Indication
A TLS extension transmitting the server name during connection establishment. It helps select a certificate on shared addresses and is not a DNS record.
