Start with the viewer's search intent
Write one sentence describing what someone will learn or see. For a video about budget photography on a phone, your primary topic might be “phone photography tips” rather than the broad label “viral”. List three specific details: the subject, the audience and the format.
Build three groups of keywords
Core: the exact subject, such as mobile photography. Specific: the particular technique, such as night mode portraits. Context: relevant audience or format, such as beginner camera tips. Choose only terms that genuinely match the content. Avoid repeating near-identical tags to fill a quota.
Examples you can adapt
Instagram reel: A beginner filming a street-food reel in Mumbai could test #MumbaiStreetFood, #FoodReels and #StreetFoodIndia. Do not use a location tag if the post was not actually filmed there.
YouTube tutorial: For “How to compress a JPG without losing too much quality,” consider plain-language tags such as image compression, compress jpg, and photo file size. YouTube tags are not a substitute for an accurate title, thumbnail and description.
LinkedIn: A practical post about automating expense reports may benefit from a few topic labels such as #FinanceAutomation and #WorkflowAutomation. Specific, readable writing matters more than hashtag volume.
TikTok: Describe the actual video and its audience. A recipe tutorial could use #EasyRecipes and #15MinuteMeals if the recipe really takes 15 minutes. A popular unrelated hashtag is not a shortcut to engagement.
A repeatable 5-minute check
- Remove misleading, irrelevant or duplicate terms.
- Check spelling and whether each tag is understandable on its own.
- Review platform-specific limits and formatting in the publishing app, as they can change.
- Publish with a clear caption or description that explains the content.
- Compare results across similar posts over time; do not attribute reach to hashtags alone.
