    Tips and Best Practices for Working with Influencers

    Whether you’re working directly with influencers or through influencer marketing agencies, it is important to follow a guideline. Best practices and guidelines are there to protect you, your clients, and the influencers themselves.

    Spend some extra time on planning and budgeting:

    • Define your campaign objectives.
    • Make sure your campaign follows your country’s advertising and sponsorship laws.
    • Set aside a budget before you identify and reach out to influencers.
    • Your budget and campaign objectives will help you decide on what type of influencer you should work with. But, if you need a thorough review on the pros and cons, check our ultimate review of macro vs micro influencers.

    Review each influencer’s profile by looking at the following:

    • Content: Are their posts of a high quality? Are the hashtags relevant? Is it authentic?
    • Audience: Does their audience look like the right group for you?
    • Promotions: How many sponsored posts do they run per month/week? Are there any obvious competitors?
    • Engagement rate: Is their engagement rate high enough for what you want to achieve?
    • Personality: Do they make a good brand fit?

    Write a detailed brief, it’s worth it!

    • Include some background on the brand or product.
    • Add a budget or budget range.
    • Include detailed campaign objects and KPIs, and clear deadlines.
    • Align your campaign brief to the influencer’s strengths (e.g. generating awareness vs creating beautiful imagery).
    • Try and give each influencer a unique URL to track their click throughs.

    Pay attention to your communication before, during, and after:

    • Your first contact should warm and personalised.
    • Before the campaign kicks off, arm your influencers with all the necessary material they need (images, hashtags, keywords, visual style guides etc.).
    • During the campaign: monitor, engage, and motivate them.
    • After the campaign: reach out to gather any reports and give them constructive feedback.
    • Use surveys or feedback forms to gather learnings and insights.
    • Pay your influencers on time, or risk reputational damage – it’s as simple as that!
    • Make a note of any influencers who stood out for the right reasons, and look at ways to build longer term relationships with them for future campaigns.

    If this all sounds like too much to handle, don’t worry, just turn to one of the world-class influencer marketing agencies listed above. You could also empower your own team with the help of influencer relationship management tools to automate certain parts of your campaign. Most of these tools also have the added benefit of being linked to massive influencer networks.
