Long tail kw, PAA, some questions

Hi,
Need to understand long tails. Most of the time longtails are questions. When I make a post to rank, is the whole question my keyword to optimize or do I transform it. Example: long tail: what do I put on for Halloween? Do I optimize for "Halloween dress"? Or the whole question

Make quality content that people like first.

For "what do I put on for Halloween," focus on intent. Use the exact question, but also include phrases like "Halloween costume ideas." This broadens your reach and nails user intent, boosting relevance for PAA too. It’s about being comprehensive, not just literal.
