Frequently Asked Questions
How many hashtags should I use?
Instagram allows 30 but engagement research consistently favours 5–15 well-chosen ones. LinkedIn and X work best with 1–3 — more reads as spam there. Match the platform's culture rather than maximising the count.
Do the biggest hashtags help?
Rarely. A tag with fifty million posts buries you within seconds. Mixing a few broad tags with several niche ones — where your post can stay visible for hours — reaches far more of the right people.
Do hashtags still matter?
Less than they did. Instagram's own guidance now emphasises content quality and keywords in the caption over hashtag volume. They still aid discovery in niche communities, but they are no longer the growth lever they once were.
Should I reuse the same set every time?
No. Identical blocks of hashtags on every post look automated. Vary them to match each post — which also gives you a read on which sets actually work.
Should hashtags go in the caption or a comment?
Instagram has confirmed both work identically for discovery. Putting them in the first comment simply keeps the caption clean, which is a design choice rather than a ranking one.

Tips for better results
- Check the result at phone size — most people will see it on a small screen, not a desktop.
- Keep important text away from the edges; platforms crop previews differently in feed and full view.
- Platform dimensions change. Re-check anything you produced more than a few months ago.
Common problems and how to fix them
The image was cropped after upload
The aspect ratio does not match what that placement uses. Pick the preset for the exact placement, not the generic platform size.
The caption was truncated
The preview limit is shorter than the posting limit. Put the essential line first.
Colours look different once posted
Platforms re-compress uploads. Avoid heavy gradients and very fine detail, which suffer most.
