By studying the target audience and market demand, we can better understand the search vocabulary used by potential customers and determine the topics to be covered by online promotion soft articles.

Determine the theme of keywords: determining the theme of online promotion soft text is the basis for selecting keywords. Keywords should accurately reflect the theme of online promotion soft articles and match the target audience and market demand. For example, online promotion of healthy diet can select some related keywords, such as "healthy diet", "nutritious meal" and "diet". Use keyword research tools: Using some keyword research tools can help you determine more accurate keywords and understand the search volume and competition of these keywords. For example, you can use GoogleKeywordPlanner, SEMrush, Ahrefs and other tools to search for related keywords, and check their search volume and competition. Choose long-tail keywords: When choosing keywords, long-tail keywords are usually more advantageous than single keywords. Long tail keywords are keyword phrases composed of multiple words, which are more specific and meet the needs of searchers. For example, "healthy diet" is a single keyword, while "healthy diet menu" is a long tail keyword, which is more targeted. Avoid competitive keywords: When choosing keywords, avoid choosing competitive keywords. These keywords usually have a high search volume, but the ranking is also very difficult.
