Content Topic:
A blogger's content should align with what you're promoting. This doesn't mean posts have to be strictly on-topic, but your ad should fit within the format—organically and logically. For example, an ad for children's products by a sports blogger or a nightclub by a young mother might confuse followers.
Audience:
A blogger may have a thousand likes on each peru cell phone database post, but that doesn't mean their followers are your target audience. Request statistics: who follows them, where they're from, their age, and gender. It's important that your ads reach those who are truly interested.
Tone of Communication
: Study how the blogger conducts themselves in stories, broadcasts, and reels. What are their values? How do they communicate with their audience? If their style of presentation or personal views conflict with your company's image, it's best to look for another candidate. Be especially wary of controversial topics, 18+ content, or political statements.

Reputation:
Before contacting them, simply search for their name. Have they been involved in any scandals? Have they participated in questionable campaigns? All of this could impact your brand if you decide to collaborate with them.
Once a blogger passes this "preliminary filter," you can move on to analyzing engagement, reach, and follower activity. This will help you understand whether you're dealing with a truly influential author or simply a beautifully designed account with fake followers.
