Hashtag strategy tips

Mix sizes

Combine broad hashtags (1M+ posts), mid-range (10K-1M), and niche (under 10K). This maximizes both reach and discoverability.

Be specific

#marketing is too broad. #b2bsaasmarketing is specific. Specific hashtags attract your actual target audience, not random scrollers.

Research competitors

Look at what hashtags successful accounts in your niche use. Don't copy them all, but use them as inspiration for your mix.

Rotate regularly

Don't use the exact same hashtag set every post. Rotate between 3-4 sets to avoid being flagged as spammy by algorithms.
