1. Keep it Short and Sweet
When choosing a hashtag, make sure that it´s easy for users to remember and that it´s easy to spell. Short and concise hashtags are more effective and compelling than #verylongonesthatarehardtoread.
2. Pay Attention to Formatting
Hashtags should consist of a word or phrase with no spaces or punctuation in between in order for them to be clickable by users. The #underscore_is_an_exception but why would you do that when you can make hashtags more readable by starting each word with an uppercase letter like #PayAttentionToFormating? It looks neat and it will definitely eliminate the chance that your audience will forget to type the underscore and will therefore get lost in the conversation.
3. Create Unique Hashtags
Try to create one that will stand out of the crowd and differentiate you from your competition. Using hashtags like #conference or #webinar are too general to trigger conversations related exclusively to your company.
4. Promote Your Hashtag
To trigger the buzz and the volume of conversations you are aiming for, help your hashtag out with promoting it anywhere you can. Stick it on to your website, to all your social media channels, to your email signature and even to your marketing materials.
