It’s a noisy topic with a lot of conflicting advice, so it’s smart to seek clarity.
Short Answer: Use three to five highly relevant hashtags placed directly at the end of your post. Focus on a strategic mix of niche and broad terms that accurately describe your content.
A better way to think about hashtags is not as a magic trick for reach, but as a filing system to categorise your content for the right audience.
First, let’s address a harmful practice: stop putting your hashtags in the first comment. That is an outdated tactic that no longer provides any algorithmic benefit and simply makes your post look untidy. Second, the ideal quantity is between three and five. This gives the platform enough data to categorise your post without it appearing spammy, and any more than five gives you diminishing returns. Third, your selection should be a strategic mix. You want one or two broad hashtags like #projectmanagement to define the general topic, followed by two or three niche hashtags like #agilemethodology to attract a more targeted, high-intent audience. Finally, your hashtags must align with the content format; a technical video tutorial should have different, more specific tags than a short text post about general leadership principles.
Cheers,
Jeff.
