How to Turn Keywords Into Hashtags

Not every keyword becomes a good tag

A keyword like 'how to store sourdough starter in the fridge' is excellent for an article and terrible as a hashtag: joined together it becomes an unreadable wall of letters nobody will ever type.

Before converting, shorten each keyword to its two or three most meaningful words. Conversion is a formatting step, not a thinking step.

Choose a casing convention

Lowercase is the most common convention and looks natural in a caption block. PascalCase is more readable for long tags and genuinely helps screen readers announce the separate words.

Platforms treat tags case-insensitively, so casing is about human readability rather than matching.

Decide about single words

Splitting a phrase into its individual words gives you broader tags, which reach more people but describe your post less precisely. Add them deliberately, not automatically, and only when the single word still describes your content.

Clean afterwards

Conversion can produce duplicates, especially when several keywords share words. Run a deduplication pass, then check for accidental unintended readings created by joining words together — this is the one failure mode worth reading every output for.
