2. The benefits Hashtags bring

Hashtags are used as a way to promote brand recognition. Some of the main benefits that hashtags bring can be mentioned as follows.

Using hashtags on social media posts means that users or brands are connecting with people who share similar interests or topics on that social network. And through that hashtag, the content posted by individuals and brands is supported to spread and attract higher interaction rates. Not only that, but these tags also help the posted content have more chances to show up.

Creating and using brand-appropriate hashtags and meaningful messages is also an effective way to advertise your brand and promote reach and attract target users.

For example, Oreo ran a campaign with the hashtag #MyOreoCreation that encouraged followers to come up with their imaginative Oreo creations.

And they have attracted many users from all over the world to participate in this campaign with all kinds of creative cake flavors.

The number of hashtags used on Youtube should be at most 15 because YouTube’s algorithm will ignore all your hashtags. Worse, your content may be flagged for being judged as spam. Therefore, it is recommended that users only use 3-5 hashtags for content on Youtube.
