Frequently Asked Questions
How many hashtags should I use on Instagram?
Instagram recommends using 3 to 5 highly relevant hashtags. However, many creators see success with up to 20. This tool provides 30 tiered options so you can mix and match for best reach.
What is the character limit for an Instagram caption?
Instagram captions can be up to 2,200 characters, but only the first 125 characters appear before the 'more' cut-off. Make your hook count in those first two lines.
Should I put hashtags in the caption or the comments?
Both approaches work. Putting hashtags in a comment keeps the caption looking clean, while including them in the caption makes them immediately active upon posting.
Does the tone of a caption actually affect engagement?
Yes. Captions that match the audience's language and emotion see significantly higher comment rates. A casual, relatable tone often outperforms formal or overly promotional text.
