Usage tips
Technical term
'Penetration' (penetration) is a technical term or a very formal word in all its meanings. In normal everyday language, one would more likely say 'das Eindringen' (entry/penetration) or 'die Verbreitung' (spread/distribution).

EXAMPLE
Der neue Marketingplan soll die Penetration des Marktes erhöhen.
The new marketing plan is intended to increase market penetration.
Context is decisive
The exact meaning of the word depends entirely on the topic. Words like 'Markt' (market) or 'Produkt' (product) point to business, 'sexuell' (sexual) to the physical context, and 'Material' (material) or 'Strahlung' (radiation) to a technical or physical process.
EXAMPLE
Die Forscher maßen die Penetration der UV-Strahlung.

Penetration vs Verbreitung
spread / distribution
'die Verbreitung' and 'die Penetration' can both refer to how widely a product or idea has reached people. 'Verbreitung' is the normal, general word: something becomes known, used, or distributed. 'Penetration' is used in this sense mainly in business, when talking about the penetration of a market. It sounds more technical and is not suitable for every everyday text. Learners may confuse the words because both occur in contexts involving products and customers. For ordinary situations, 'Verbreitung' is usually more natural; 'Penetration' fits better in market analyses.
Penetration
Wegen der starken Konkurrenz bleibt die Penetration des Marktes gering.
Because of strong competition, market penetration remains low.
Verbreitung
Die Verbreitung der neuen App begann zuerst in großen Städten.
The spread of the new app first began in large cities.
