Topic Research for question mapping
SEMrush Topic Research (under the Content Marketing toolkit) generates a visual topic map - a hub-and-spoke model of subtopic cards for any seed keyword. Each subtopic card shows: top 10 related questions (pulled from Google Autocomplete and PAA data), top 10 related searches, related articles from across the web, and difficulty estimates. AEO application of Topic Research for question mapping: (1) Enter your topic area (e.g., 'AEO content optimization') into Topic Research. (2) Review all generated subtopic cards - each card is a potential content cluster hub, each question is a target AEO query. (3) Switch to 'Explorer' view to see question data in table format - sortable by search volume, topic efficiency, and difficulty for prioritization. (4) Toggle 'Show only questions' - this filters Topic Research output to show only the question-format queries across all subtopics. For AEO, question-format queries are the primary target. Export all questions as a CSV for content planning. (5) Identify subtopics with high question counts and moderate difficulty - these are your highest-potential AEO cluster topics where comprehensive FAQ content can dominate citation share.
