Use Google Auto Suggest: When you start typing in a query in Google search bar, Google will automatically suggest queries that users are searching for.

Analyze your Competitor’s keywords: Use a tool like SEMrush or Ahrefs to see the keywords your competitors are ranking for.

Use Long-Tail Keywords: Long-tail keywords are longer and more specific keyword phrases that visitors are more likely to use when they are closer to a point-of-purchase or when they are using voice search.

By using a combination of these methods, you can get a good idea of the keywords that are currently trending and relevant to your industry. It is important to choose keywords that have a high search volume and low competition for your SEO strategy to be effective.
