Source Quality

Not every source carries the same value. Primary sources, official documentation, authorities and institutions, research papers and proprietary data with transparent methodology are especially high quality. Blogs without methodology or AI-generated summaries are weak as factual sources.

Sources are particularly important for:

• statistics, percentages and benchmarks,
• studies and trends,
• legal, medical and financial statements,
• technical standards,
• claims about Google or AI systems.

For your own recommendations, clearly labeled experience, internal processes or simple definitions, an external source is usually not needed. The principle: if a statement must be verifiable, it needs a robust source. Good source qualitySource quality shows whether important statements are backed by reliable evidence. It does not mean adding links indiscriminately, but providing robust support for verifiable claims.Open glossary entry → strengthens trust, traceability and the conditions for AI visibilityAI Visibility describes whether and how visible a brand, website or person is in AI-generated answers.
