TikTok: the favorite for taking off from scratch

Without a doubt, TikTok continues to be the platform that best rewards small accounts. Its algorithm is not based on the number of followers, but rather on the content’s ability to retain attention and generate quick engagement.

Data from the Metricool report:

  • +70.25% increase in reach
  • +71% growth in watch time

What it means: A quality video can go viral even if the account has fewer than 1,000 followers. Discovery is meritocratic and non-cumulative, leveling the playing field.

Advantages for small accounts:

  • Algorithm prioritizes recent content
  • Possibility of organic growth without paid ads

Which algorithms are most friendly for growing without ads?

1. TikTok: pure discovery algorithm

It evaluates each video individually and shows it to new audiences from the very first minute. If the video generates good retention and reactions, it keeps scaling.

2. YouTube Shorts: extended lifecycle

You don’t need immediate virality. A video can be rediscovered weeks or months later if it matches a user’s search or behavior.

3. LinkedIn: prioritizes niche relevance

It values the quality of the conversation generated. A good post can remain visible for several days, especially with meaningful interactions.

Where to start if you have few followers?

If you’re just starting your digital presence, the Metricool study is clear: TikTok is the most accessible platform to grow quickly, while YouTube Shorts offers sustainable scalability. For those seeking conversions in professional sectors, LinkedIn is an effective option from day one.

Organic growth is still possible in 2025, as long as quality content is combined with the right platform choice. Making the right choice from the beginning can be the difference between posting into the void or building a community from scratch.
