How to determine the advertiser theme

There are many ways to determine an advertiser's topic, here I offer you a simple method based on text analysis.

Collect data

You need to collect all text data related to the advertiser, such as slogans, promotional articles, customer reviews, etc. These data will be used for subsequent text analysis.

Preprocess the data

Before you can start text analysis, you need to pre-process the collected data. This includes removing stops, punctuation marks, special characters, etc. In addition, you can convert the text to lower case to avoid problems caused by case differences.

Extract keywords

Use natural language processing libraries (such as NLTK, spaCy, etc.) to extract keywords from preprocessed data. These keywords will be used for subsequent text analysis.

Analyze keyword distribution

Analyze the distribution of the extracted keywords in the text data. This can help you understand the advertiser's main themes and concerns.

Generate theme words

According to the distribution of key words, generate theme words. These headings will be used for subsequent text analysis.

Evaluate subject words

Methods such as correlation analysis are used to assess the similarity of the generated topic words to the advertiser's actual topic. This can help you determine if the subject line accurately reflects the advertiser's main theme.
