If a text is excessively enriched with keywords, this is known as keyword stuffing.
The text will typically appear artificial and less appealing to read, and it will therefore generate fewer inbound links. Pages that place their bets on a single keyword often exhibit a lack of semantically related terms and broad vocabulary, and in the long-term, this leads to a lower website ranking.
The relative number of keywords that can be accommodated in a text before it be perceived as keyword stuffing is not set in stone.
Crispy Tip: Create content for people, as texts that are smooth to read are less at risk of being classed as black hat SEO by Google’s search algorithm.Glossary index
