1. Don't put all your eggs in one basket.
Social media marketing is a battlefield. In this case, don't be Jon Snow. If you've watched Episode 9: Battle of the Bastards, you know just how royally screwed Jon Snow got when he put all his trust in his meager (but hardcore) wildling army. In social media marketing world, this is the same as putting all your budget into ONE ad.
Instead of putting $1,000 into one super ad, put $100 into 10 different ads. You'll be able to test and figure out which ads are most effective, and in turn, invest more in those in the future. Thank the heavens that Sansa came in an saved Jon's ass just in time, but you might not always have Knights of the Vale, on in this case, an extra $1,000 to spend when your ad fails.
2. Design matters.
In the opening credits of Episode 9 in this season's Game of Thrones, you might've caught the Stark sigil back on top of Winterfell. What you may have missed, is that instead of a gray wolf on a white background, it's the reverse. It's a white wolf on a gray background - Jon Snow's sigil.
These may be minor details to most, but the design of your content should reflect your brand in every way. Each piece of content you post should reflect your brand - a blog post should have imagery that adheres to your design guidelines, a social media image should have your brand's colours and fonts, etc. Don't overlook the details, they help tell your story.
3. Don't be a jerk.
This one should be obvious, but you'll be surprised how many people get it wrong. Perfect example: Jon Snow. Perfect bad example: Ramsey Bolton. Being a jerk to people will get you eaten by rabid dogs.
Just kidding (sort of). But hey, being nice gets you things! Being nice to your customers and clients will get referrals, being nice to your audience will grow them into your brand's loyalists. Extra credit: If you can get influencers on your side, even better (In Jon's case, badass 10-year-old Lyanna Mormont won him the votes he needed to secure the North).
4. Be consistent and you'll eventually get what you want.
Play the long game. Short-term victories are great, but don't ever lose sight of your long-term goals. Case in point: Cersei Lannister. She schemed, planned, and connected with necessary allies to win the Game. In the end, she burned down her enemies in an explosion of wildfire and won the throne.
In order for your social media marketing to be effective and bring you maximum success, you have to post, analyze, and engage every day. A spike in engagement on one day means nothing if you don't post anything for the next month. Don't allow yourself to fall behind, work at your campaign every day and in the end, you'll reap the profits.
5. Don't abandon who you are.
Remember why your company exists. That should be the central focus of all your operations. Don't change your core principals to adapt to hypes. Social media is merely a tool for you to get your brand's message out there. You are Arya Stark of Winterfell, dammit, don't you forget it.
