Your handle (@username) and profile name are critical for SEO on Instagram since they can directly trigger profile discovery during search.
Tips for Handle and Username Optimization

Captions are actively scanned by Instagram search, making keyword placement important. Yet, readability and engagement trump keyword stuffing.
Effective Caption Writing
- Lead with a keyword hook early in your caption
- Write in a natural sentence rhythm
- Integrate related synonyms to diversify
- Include a call-to-action (CTA) to prompt engagement

Use Relevant, Trending, and Branded Hashtags Strategically

Hashtag Strategy
| Type | Example | Purpose |
|---|---|---|
| Relevant | #VeganCooking | Matches niche and keyword intent |
| Trending | #MondayMotivation | Captures high-volume seasonal/weekly moments |
| Branded | #MyBrandStory | Owns a proprietary searchable content thread |

Combine different hashtag types to cover diverse audience segments while maintaining relevance.
