A server with defined provider management such as OS updates and monitoring. Scope depends on the agreement and may exclude customer applications.
Definition and sourcesMariaDB
A relational database system originating from MySQL. Compatibility is broad but not complete across all versions, features and tools.

Ads delivered within Facebook through Meta's tools. Placement, objectives and targeting depend on campaign settings and platform rules.
Definition and sourcesMeta description
A page description supplied in meta name="description". Search engines may use it or choose another content excerpt. It should accurately describe the page; it is not guaranteed search-result wording.
Definition and sourcesMeta robots
Instructions to supporting crawlers about indexing or result presentation, supplied in HTML or X-Robots-Tag. Crawlers must access the response to read noindex. These instructions are not access controls.
Definition and sourcesMeta tags
HTML meta elements supplying metadata such as encoding or a description. Page titles use the separate title element. Adding meta keywords does not improve Google rankings.

Practices for maintaining machine-learning models, data, deployments and monitoring. They address changes in data and model quality after production launch.
Definition and sourcesMobile-first indexing
Google's use of mobile content for indexing and ranking. It does not mean a separate phone-only index; content parity between views matters.
