Sentiment Analysis

Definition

Sentiment analysis is an NLP technique that evaluates the emotional tone of text, classifying it as positive, negative, or neutral, and is used by search engines and AI systems to assess the reputation and reception of a business or content piece. When Google evaluates whether your business has good reviews, whether press coverage is favorable, and whether social mentions are positive, sentiment analysis is part of what drives those assessments. It connects directly to the Trustworthiness component of E-E-A-T.

How It Works

Sentiment analysis models scan text and identify linguistic signals of positive or negative tone: word choice, sentence structure, the presence of complaint language, and the ratio of praise to criticism. These signals are aggregated across many sources to form a sentiment profile for a business or topic.

For your business, sentiment analysis applies to: reviews on Google, Yelp, and industry directories; social media mentions; press coverage; and responses to public complaints. Platforms like Google use these signals to determine how trustworthy and user-approved a business is. AI tools trained on web content also absorb these signals, which affects whether they recommend a business positively or flag it with caveats.

Why It Matters

A business with hundreds of negative reviews is sending a strong negative sentiment signal that AI systems will register. A business with consistent, specific, positive reviews is building a credibility signal that feeds into how confidently AI tools will recommend it. Proactively generating genuine reviews from satisfied clients and professionally responding to complaints are the two most direct ways to manage sentiment signals.

Example

A moving company in Portland has 180 Google reviews with an average of 4.8 stars, and several reviews mention specific positive details about careful packing and punctuality. When someone asks an AI tool for "reliable movers in Portland," sentiment analysis on the review corpus helps position this company as a trustworthy option. The AI may explicitly note high ratings when mentioning them.
