A marketing manager looking for an influencer for a campaign usually starts from the same place places: open Instagram, find a profile with a large number of followers in a relevant niche and send a message. Sometimes it works. More often than not it doesn't work.
The problem is not with the influencer. The problem is in the selection process. The number of followers is visible immediately, but everything else that actually determines the success of the campaign requires a little more work to verify.
This guide goes through the entire process step by step, from defining goals to signing an agreement, with concrete criteria you can apply immediately.
Step 1: Define the campaign goal before anything else
Different goals require different types of influencers. A marketing manager who does not distinguish this at the beginning spends the budget on the wrong profile.
- Brand awareness: you need reach. A macro or mega influencer with a large audience, even with lower engagement, spreads the brand name quickly and widely.
- Direct sales or conversion: you need trust. A micro-influencer with a niche audience and high engagement who recommends the product as a personal recommendation, not as an ad.
- Long-term brand presence: you need consistency. Ambassador model with one or two influencers who regularly mention you over several months.
- UGC content for own channels: you need creativity and production value. UGC creator who shoots for you, without posting on his profile.
Tip: Define KPIs before you start looking. If you don't know how you're going to measure success, you can't even know if you've chosen the right influencer.
Step 2: Choose a platform according to the target group
An influencer who does great on TikTok may not have any impact on the Instagram audience, and vice versa. The platform is not a detail, it is the basis of the entire strategy.
- Instagram: lifestyle, fashion, beauty, food, fitness, travel. Audience 18-35 years old. Stories for direct conversions, Reels for reach.
- TikTok: younger audience (16-28), viral potential, perfect for new product launches and trends. High organic reach.
- YouTube: longer format, more trust, perfect for reviews, tutorials and premium products. Longer content life.
- Facebook: older demographic (30-50+), good for local brands, specials and discounts. Groups and pages for niche communities.
5 criteria to choose the right influencer
-
Engagement rate, not the number of followers
Look for influencers with an ER above 3% on Instagram or above 5% on TikTok. Anything below that means the audience is passive. Formula: (likes + comments) divided by the number of followers, multiplied by 100.
-
Niche Relevance
An influencer who posts about food and fitness occasionally does not mean that he is right for your health food brand. Look at the last 30 posts: what proportion is directly relevant to you?
-
Audience Demographics
Search for screenshots from Instagram Insights or TikTok Analytics. Check age, gender and location. If your target group is women 25-35 in BiH, and the influencer has 70% male audience from Serbia, cooperation will not bring results regardless of everything else.
-
Previous collaborations and brand fit
Has the influencer previously worked with competitors? What did that content look like? Did the audience react positively? An influencer who advertises everything they can find doesn't build trust, and then your campaign won't have credibility either.
-
Authenticity of tone and communication
Read comments below posts. Do followers ask for opinions? Does the influencer fit? Is there a real community or are the comments just emojis? The community is what sells, not the image itself.
Red flags that should be recognized immediately
Not all profiles are what they seem. Here are the telltale signs that something is wrong:
- A sudden spike in followers of several thousand in a short period of time without a viral post to justify it
- Engagement rate below 0.5% with a large number of followers
- Comments that are generic, unrelated to the content posted ("Great post!", "Nice!", link spam)
- A profile that advertises everything with no visible niche logic: today supplements, tomorrow cryptocurrencies, the day after tomorrow travel packages
- Influencer who refuses to show statistics from Insights or Analytics tools
- Mismatch between Reels views and followers: 200 views videos on a profile with 50,000 followers is a strong signal of fake followers
Warning: Fake followers are still a widespread problem in the Balkans. It always asks for a screenshot of Insights data directly from the influencer, and for the last 30 days, not an annual average that can mask a decline.
What to check in Insights data
When an influencer sends an analytics screenshot, look at this specific data:
- Average reach per post in the last 30 days
- Rate of impressions coming from followers (vs. non-followers)
- Geographic audience distribution (top cities and countries)
- Demographics by gender and age
- Average engagement by format (Reels vs. static post vs. Story)
Negotiation and agreement
When you find the right influencer, comes the negotiation. A few things to define in the brief:
- Format and number of posts: how many Reels, Stories, static posts
- Delivery deadline: when the content is published
- Usage rights: can you use the content in paid ads and for how long
- Content approval: does the brand see and approve the material before publication
- Exclusivity: is the influencer not allowed to work with direct competition for a certain period
Tip: A good brief saves both your and the influencer's time. The more precisely you define expectations at the beginning, the less chance there is for misunderstandings that slow down the campaign and disrupt deadlines.
How Influexus simplifies the whole process
You can do all the steps described above manually, but it takes time. A marketing manager who manually searches profiles, sends cold messages, waits for responses and then negotiates spends hours on work that can be automated.
Influexus is the only platform for influencer marketing in the Balkans where brands can search creators by niche, platform, location and number of followers in one interface. Each creator has a public profile with packages and prices, so you know immediately what you're getting and at what price.
Payment goes through the escrow system: you pay in advance, and the influencer receives the money only when he delivers the agreed content that you approve. No awkward situations, no "I paid and the content never arrived".
For a brand that is working with influencers for the first time, this model eliminates almost all risks and shortens the entire process of finding and agreeing from weeks to hours.
