After doing hours of research of watching the successful vs the unsuccessful on Tiktok, I have seen these 4 Criteria matter the most to Tiktok when judging your account:
Authority - Quality Content, Consistent Content, Level of value (Education, Inspiration, or Entertainment), Watch time, Retention, Account Age.
Engagement - Follows, Shares, Reposts, & Return Viewers. (Maybe Favorites too)
SEO/Categorization - Consistent Categorizations (Happens when you get the first two right), Accurate Categorizations, Ranking in Search on Tiktok & Google Search Engine, Shows Expertise.
Spam Score - Spam posting, Using “Bot” language, L4L, F4F, Engagement Groups, Spam comments unnatural use of Tiktok.
