I. The 'New Account Boost' Hypothesis
TikTok
LIKELY. De facto boost via initial 300-500 viewer content test.
YouTube
LIKELY. Reports suggest a temporary "welcome gift" of increased impressions.
X
UNCLEAR. Conflicting data suggests either informal advantage or slight initial down-weighting.
UNLIKELY. No evidence of account-level boost; focus is on immediate engagement.
UNLIKELY. Ranking based on predicted user value, not account age.
II. Hierarchy of Engagement Signals
Not all interactions are equal. The following visualizes the relative algorithmic weight of high, medium, and low-value signals for new content.

IV. Refuted Postulates / 2025
MYTH: Hashtags are inert.
FACT: Diminished, but 3-5 relevant hashtags provide a significant boost (+29%) for accounts <1K followers.
MYTH: High frequency is mandatory.
FACT: Quality has surpassed quantity. Data indicates 3 high-quality posts outperform 5 low-quality posts.
MYTH: "Shadowbanning" is used to drive ad spend.
FACT: Officially debunked by Instagram. Visibility issues are transparently shown via 'Account Status' tool.
MYTH: Algorithms exclusively favor large accounts.
FACT: Widely debunked. Systems are designed to surface high-quality content regardless of origin to maximize user session time.
V. Actionable Strategy
Optimize for Social SEO from Day One. Your profile is an indexable asset. Utilize specific, relevant keywords in your bio, username, and initial captions to signal your niche and intent to the algorithm.
Engineer for High-Value Interactions. Do not treat all engagement equally. Content's primary objective should be to generate the highest-weighted signals: Saves [Instagram], Replies [X], Shares.
Leverage the Initial Visibility Window. Whether a formal "boost" or content test, the initial weeks are critical. Post with quality and consistency (3-5 times/week) to capitalize on any potential early algorithmic advantage.
