Text Mining

Text Mining

Definition

Text Mining in AI Terms in Content Marketing refers to the automated process of extracting valuable insights, patterns, and structured data from large volumes of unstructured text. Using natural language processing (NLP) and machine learning techniques, Text Mining allows businesses to analyse customer reviews, blog content, social posts, and search queries to uncover trends, user intent, and sentiment.

A trusted SEO company or performance marketing agency leverages text mining to refine keyword strategies, optimise blog content, and predict customer needs. For example, by examining thousands of search terms and customer comments, a digital marketing Auckland team can fine-tune meta descriptions, page titles, and blog topics to match search behaviour—boosting both engagement and rankings.

It plays a critical role in understanding what drives customer interaction, which topics generate the most organic traction, and how users describe products or services in real-world language. This allows marketers to stay ahead with more relevant, informative, and compelling content.

Explained with Example

Let’s say a performance marketing agency wants to help a local NZ-based fitness equipment brand improve its content marketing. They collect thousands of product reviews and online queries like “best home workout equipment in Auckland.” Using Text Mining, they discover that customers often mention “space-saving,” “durable,” and “quick setup.”

The team then rewrites existing blog posts and landing pages by incorporating these recurring terms in headings, FAQs, and product descriptions. As a result, the website not only ranks higher but also sees increased time-on-page and conversions—because it speaks directly to the concerns and interests of potential customers.

Formulas & Calculations – Simple & Clear

Marketers use several measurable text metrics to evaluate insights from mined data. Here’s how:

MetricFormulaExample
Term Frequency (TF)(Number of times term appears / Total words in document)12/600 = 0.02
Inverse Document Frequencylog(Total docs / Docs with term)log(1000/10) = 2
TF-IDF ScoreTF × IDF0.02 × 2 = 0.04
Sentiment Score(Positive – Negative mentions) / Total mentions(40 – 10) / 100 = 0.30
Keyword Density (%)(Target keyword count / Total word count) × 100(8 / 400) × 100 = 2%

These values help Auckland SEO experts determine which words hold significance and drive targeted traffic.
