December Hashtags for Social Media – Over 100 Hashtags for 2021

Wondering what hashtags to use on social media in December?

This complete list of hashtags will provide you with over 100 popular hashtags to use on Instagram throughout December.

These hashtags can also work on other social media channels like Twitter, Facebook, LinkedIn, and TikTok.

Hashtags are an outstanding way to increase the visibility and reach of your social media posts. 

You can use up to 30 hashtags in your Instagram posts, but research from Track Maven suggests 9 hashtags is the magic number for Instagram.

On Facebook and Twitter, I recommend you use 1 – 2 hashtags, and on LinkedIn use 3 – 5 hashtags.

When compiling your list of hashtags for Instagram, be careful not to use only the most popular hashtags.

Hashtags with millions of posts are highly competitive and the chances of your content being seen are much smaller.

That’s why I’ve curated a list of popular hashtags that range from 15,000 to 1 million posts or more.

Use a variety of these hashtags in your posts for maximum results.
