Platform mechanism and algorithm
algorithm system
1: Establish video breakthrough thinking instead of account thinking
2: Target users. All elements of the video are needed by specific users.
3: Improve your data as much as possible
4: Forget the algorithm and remember the audience
The core work of Douyin: video recommendation logic
1: Guess which video you want
2: Guess whether this author is something you like to read
Collection of three label systems
1: Each viewer’s daily video viewing habits
2: How long should you stay in which video?
After collecting, label each audience member’s interests and hobbies
1: Video tag
2: Creator account label
User collaboration
3: Audience interest tags
3: Which videos have you liked, commented on and followed?
3: Guess what each audience wants to see, guess what you want to see
4: High degree of matching
1: Priority recommendation
2: Video tag Creator account tag
3: Audience tag
labeling system
Audience interest tags
Our reaction to each video
video tag for video
All the information in the video is composed of a "morpheme library"
language information
video title
Copywriting for subtitle publishing
Post copy
visual information
the way some people look
Identification of specific situations
Specific looks and clothing styles
auditory information
accent
dialect
Concrete music
User Info

specific shades and tones
Every word in the video
Characters and typefaces for shooting environments
Creator's account label
All video tag collections, information about viewers who have stayed for this account, including information about some viewers who have sent private messages, will be recorded in the tags of this account.
Leverage video tags
1: Labels cannot be defined simply by one or two words.
2: What elements do you need for the system to recognize your video?
In the early days of video, we need to learn specific elements to allow the system to identify our videos, label them, and push them to the right people.
Insert keywords, key pictures, a hot topic, benchmark bloggers, cut out some types of content from benchmark accounts, conduct discussions and comments, quickly break through the cold start period
3: Consider what the most critical, strongest, and most dominant tags below this video look like.
Please let all tags go to one place and don’t let your video be pushed to people who may affect the video data.
Pay attention to the core tags of the video
Prerequisites for high-quality video
Push to the right people
Operational methods strengthen labeling
Simple operation
Use of # sign
For example, emotion
#Knowledge
#workplace
dou vote for similar accounts
Choose similar experts
Select interest tags
Tag based on crowd portraits
Not limited to fixed topics, find topics that similar people like to read
For example, a travel vlog that expresses romance and freedom can be added to #AranyaDramaFestival
Disassemble accounts and analyze audience demands
For example, clothing accounts can be submitted to accounts that talk about aesthetics and art.

consumption data
The conversion rate of the live broadcast room and the video with goods, the consumption of gifts in the live broadcast room, and the weight of users with high consumption levels is significant.
Freshness
Push the new but not the old
The meaning of each data
1: Generally speaking, the higher the value, the better.
2: The impact of indicators in different situations is different.
Different tracks have different numbers of likes, different collections, different periods, and different indicators.
3: The highest data resists the decline in freshness until it is completely irresistible. Video prime 24 hours. Search is also an important weight.
dou
1: In the early stage, find more judges who voted for you, improve the initial data of the video, and label the video with a specific group of people.
2: Expand results based on input-output ratio Live broadcast room merchants specific number of fans
3: Forcibly change the fan model at a specific stage of the account
4: Quickly attract popularity. The better the data, the stronger the freshness. It will be delivered within 2-6 hours (fan tag, video tag, account tag) under relatively accurate conditions.
5; Activate the old account with "money ability"

Early days
narrow range
hobby
The benchmarking experts choose those with the smallest number of fans and whose content is not as good as their own.
long time
The initial launch must be extended to 24 hours, the longer the better. Extend the time to allow the machine to learn.
Rely on nature
The iron fan mechanism does not recommend voting to increase followers. Investing in likes and comments from similar user groups will naturally increase the number of fans. It is easy to affect video data. Try to vote in likes and comments from similar user groups to naturally increase the number of fans.
medium term
Intelligent placement hits high popularity
Calculate input-output
later stage
Accurate attack, accurate breakout of the circle, specific fan groups, specific groups of people, help yourself break out of the circle, break through the traffic
Iron powder mechanism
1. De-homogenize. Don’t repeat your video content.
2. Deepen the relationship between users and bloggers and increase the value of individual users. Douyin promotes the commercialization of users.
3 No need for more heads to protect new account
4 In the long run, the threshold will become higher and higher
