Preparing a Media Kit. The advertiser doesn't care about your likes, they care about: Demographics: Gender, age, and country of viewers. Retention: How many minutes on average your videos are watched. Active core percentage: How many views a video gets in the first 48 hours. Examples: Links to your best videos where integration would look organic.
How to find an advertiser?
You don't need to write to everyone. Look for those who: Are already advertising with your competitors. Produce products that you actually use (native advertising is always more expensive). Use platforms like YouTube BrandConnect, StoryClash, or TrendHERO to see which brands are actively looking for bloggers in your niche right now.
Cold Email (Pitch)
You shouldn't write 'Hi, buy ads', but offer a solution to their problems. Email subject: Should be clear, for example: 'Collaboration: [Channel Name] x [Brand] — reach of 50k target audience'. Essence: 'I looked at your new product [name]. My audience is [who they are], and I can integrate your service into a video about [video topic], which will be released on [date]'.
Where to look for contacts?
About (About the channel): Large companies often have an email for 'Business Inquiries' listed there. LinkedIn: Find the Influencer Marketing Manager or PR Manager of a specific company and write to them directly. This works best. Company website: Look for the 'Affiliates' or 'Press' section in the website footer.
What to negotiate (Formats)
Integration (Pre-roll/Mid-roll): A 60–90 second insert inside the video. Exclusive video: The entire video is dedicated to the product (review). Ambassadorship: A 3–6 month contract (a series of integrations + posts in the 'Community' tab). This is the most profitable option for the creator.
Legal aspect
In 2026, in many countries (including the EU and the US), it is mandatory to check the 'Video contains paid promotion' box in YouTube settings. This is a requirement of the advertising transparency law.
Don't be afraid of anything. Develop your brand, raise your status, increase your audience reach not only on YouTube (it's just a website). Knock, and it shall be opened unto you!
