There is power in relevancy. When it comes to online content, it can appear easy to build connections, but it is, in fact, harder. Through social media, we lose the human interaction and the ability to experience non-verbal communication. However, there are opportunities to build connections with people across the world, and it can be through socially relevant holidays and days of observance that we celebrate primarily online.
Of course, we have our traditional holidays, like New Year’s Day, but there are quirky, unique holidays that are designed to bring awareness and conversation to important topics throughout the year. Some brands have utilized hashtag holidays to connect with their audience and it’s worked exceptionally well with sparking discussion and brand loyalty.Social media holidays can bring fun, thoughtful engagement to your profile. Plan proactively to avoid scrambling for content for last-minute participation. #ContentMarketing | #SocialMedia | via @AltimeseNichole Click To Tweet
Social media can encompass two different lanes of responsibility: strategy and execution. If we’re not careful, we can place more emphasis on one more than the other. To ensure a strategy isn’t put on the back burner, proactive planning is essential.
