What is Tacit Knowledge?

Tacit knowledge, also known as implicit knowledge, is a type of knowledge that is difficult to formalize and personal, usually based on experience, intuition, and perception. Unlike explicit knowledge, tacit knowledge is difficult to convey through words, data, or formulas. It is often deeply embedded in an individual’s behavior, skills, or culture, and relies on practice and personal experience to acquire.

For example, learning to ride a bicycle is a typical example of tacit knowledge. Although you can describe in words how to hold the handlebars, keep your balance, and pedal, these instructions cannot really convey how to keep your balance during actual riding. Only through repeated practice will you “understand” how to ride freely at a certain moment. Similarly, the skills of a craftsman and the handling of complex interpersonal relationships require long-term practice to master, rather than relying solely on written knowledge.

Search Engine Marketing (SEM) refers to strategies and tools that enhance a brand’s visibility in search engine results, thereby attracting more traffic and potential customers. Imagine your target audience searching online for information related to your product or service, and your brand appears at the top of the search results—this significantly increases the chances of users clicking through to your website.

SEM primarily relies on search engine advertising platforms like Google Ads or Bing Ads. Businesses bid on specific keywords to ensure their ads appear in relevant searches. When users search for these keywords, they see the ads you’ve bid on.

What Is Keyword Research and Targeting?

Keyword Research: Understanding How Users Search

Keyword research refers to analyzing data to identify the words or phrases users commonly use in search engines. These keywords are often not just single words but search phrases with clear intent, such as:

• “Best coffee machine for small apartments”
• “High value laptops in 2025”
• “Which baby stroller brand is good”

Through keyword research, we can understand what potential users truly care about, their preferences, and how they express themselves, allowing us to create content that better fits their search habits. Good keyword research makes content more aligned with real searches and improves its chances of being recommended by search engines.

What is SEM Copy?

SEM (Search Engine Marketing) copy refers to text content specifically created for online ads, designed to attract clicks and boost conversion rates. SEM copy must not only catch attention but also be practical, guiding potential users to take action—directly impacting ad performance and ROI.

Understanding SEM Ad Structure: Three Key Elements

1. Headline: The first element users see in search results. A compelling headline effectively grabs attention and sparks click-through desire.

—cref command stands for “Character Reference”. It is mainly used to extract character features from reference images and apply them to new images to achieve coherence and consistency in character design. It allows users to specify one or more images as content references. Midjourney will use these reference images to help generate images with similar content. This feature is more suitable for anime or games.

What is a workflow?

A workflow is a set of predefined, standardized steps that can be used to complete a specific task. A workflow contains multiple nodes, each of which completes a fixed task.

To give an example that is not very appropriate but easy to understand, we are all familiar with the brain teaser “How many steps does it take to put an elephant in the refrigerator?” The answer is three steps: open the refrigerator, put the elephant in, and close the refrigerator. In this scenario, these three steps constitute the nodes of the workflow “Put the elephant in the refrigerator”.
