N-Gram analysis is a method in natural language processing (NLP) used to examine texts and data by analyzing sequences of consecutive elements. In digital marketing, N-Gram analysis can be employed to optimize search terms for Google Ads, identifying patterns and relationships in search queries. This leads to improved ad relevance and more effective data analysis. To conduct an N-Gram analysis for Google Ads, data collection and processing are required, with Google BigQuery serving as a helpful tool.
