Definitions beginning with G

GA4

Google Analytics 4: current version of Google Analytics, organised around events and users.

In practice: validate events and definitions before building a conversion report.

Gateway

In a web architecture, an intermediary receiving a request and forwarding it to another service. An HTTP gateway or reverse proxy may apply routing, authentication or rate limits. It should be distinguished from the destination service, whose errors and delays require separate diagnosis.

In practice: when an action fails, identify whether rejection comes from the gateway or destination service. Check timeouts, request identifiers and error propagation without recording secrets in logs.

GDPR

European regulation governing personal-data processing and the rights of affected individuals.

Reference: CNIL · RGPD · Source consulted 2026-10-31

In practice: Map actual data and purposes, then consult official sources for applicable obligations.

Generative AI

Generative artificial intelligence able to produce text, images, audio, code or other content from instructions.

In practice: Choose a verifiable task, define permitted data and review outputs before publication.

Generative search

Search experience composing a synthetic answer with an AI model, often alongside a list of sources or results.

In practice: Compare generated answers with the original source and fix ambiguities on your pages.

GEO

Generative Engine Optimization: an industry label for clarity, sourcing and discoverability work aimed at generative answers. It is not universal markup or a citation guarantee; Google describes its own eligibility conditions.

Reference: Google Search Central : AI features · Source consulted 2026-10-21

In practice: Define target questions, published evidence and a repeatable monitoring method.

GeoJSON

JSON-based geographic data interchange format describing points, lines and polygons, among other objects. RFC 7946 uses WGS 84 decimal degrees, with longitude before latitude in a position. Correctly written geometry establishes neither survey accuracy nor the existence of a public entrance.

Geolocation

Estimation or determination of a device or user’s geographic position from authorized signals.

In practice: Explain the feature before requesting location and offer manual entry.

Git

Distributed version-control system preserving code change history and supporting collaborative work. A commit describes a recorded state and its history links. Untracked local files are not automatically protected by that history.

Reference: Git · What is Git? · Source consulted 2026-10-25

In practice: connect each change to a reason and verify the rollback procedure.

Glyph

Visual form representing a character or combination of characters in a font. Characters and glyphs do not always map one-to-one, particularly with ligatures and complex scripts.

Build a sample with accents, symbols, numbers and scripts used on the site before approving the font.

Google Ads

Google advertising platform for running ads in search, partner websites, applications and videos.

In practice: Connect each ad group to a suitable page and review triggered queries.

Google Analytics

Service for audience measurement and interaction analysis across websites and applications.

In practice: Define useful events and check their collection across a full test journey.

Google Business Profile

Business profile used to manage local information in Google Search and Maps.

In practice: keep hours, contact details and business location consistent with reality.

Google Search Console

Google tool providing information about indexing, search performance and certain technical website issues.

In practice: Compare clicks, impressions, queries and pages over the same period before drawing conclusions.

Googlebot

Generic name for crawlers used by Google Search to retrieve Web resources.

In practice: Check that an important page returns a valid status and useful content to both crawler and visitor.

GPU

Graphics processing unit suited to parallel computation and widely used to train and run AI models.

In practice: Measure work that truly benefits from the hardware before paying for dedicated capacity.

GraphQL

Query language and runtime for APIs allowing clients to request exactly the data they need.

In practice: define data needed by a screen and measure actual queries.

Grounding

Mechanism connecting a model answer to retrieved data, documents or results to improve accuracy and verifiability.

In practice: check that each important claim can be traced to a supplied, correct source.

Growth hacking

Experimental growth approach combining product, data, content and acquisition to find rapid levers.

In practice: State a measurable hypothesis and check its effect on customer relationship quality.

Guest blogging

Publishing an article on a third-party website, generally to share expertise, reach an audience and gain a reference.

In practice: Choose a topic useful to the host audience and clearly identify the author and relationship.

gzip

Compression format used for transferring text responses on the Web. The client advertises accepted encodings and the server identifies the applied encoding with Content-Encoding. Check the received response rather than configuration alone; gzip reduces neither resource count nor complexity.

Reference: MDN : Content-Encoding · Source consulted 2026-10-18

In practice: Check compressed text responses and avoid recompressing already optimised images.
