What is keyword research?
What are keywords?
Keywords are the words or short phrases that users type into search engines like Google when they are looking for information, products, or services.
For content creators, marketers, and SEO professionals, keywords are a crucial element that helps websites or articles get discovered more easily on search engines. For example, if you sell cars, your keywords might be "buy car on installment," "cheap used cars," or "car loan services."
Defining keyword research
Keyword research is the process of finding, analyzing, and selecting the right keywords to optimize website content, helping to improve rankings on search engines. This process is not just about finding popular keywords; it also involves identifying terms relevant to your field that have moderate competition and the potential to attract high search traffic.
The goal of keyword research is to make your content easily accessible to users who are searching for the information you provide.
Which Google algorithm affects keyword research
Keyword research cannot be separated from how Google evaluates and ranks websites. Google continuously updates its algorithms to improve search results and provide accurate, high-quality information to users. One of the most important algorithms affecting keyword research is Panda, Penguin, and Hummingbird.
- Google Panda: This algorithm focuses on content quality. If you stuff too many keywords into your content without ensuring it remains natural and useful, your website may be penalized. Therefore, keyword research needs to focus on using keywords reasonably and naturally within your content.
- Google Penguin: Penguin focuses on detecting unnatural backlinks and keyword manipulation tactics. Keyword research today is not just about primary keywords; it must also account for other relevant factors such as backlinks and the semantic relationships between keywords.
- Google Hummingbird: Launched in 2013, Hummingbird helps Google understand the meaning behind search queries rather than simply matching keywords. This means that keyword research should not just focus on individual keywords but must also grasp the context and intent of the searcher.
Therefore, keyword research must include a clear understanding of these algorithms to select high-quality keywords, avoid deceptive practices, and create content that provides real value to users.
5 types of keywords in keyword research
When conducting keyword research, you will encounter many different types of keywords, each with its own purpose and role in your SEO strategy. Below are the common types of keywords in keyword research:
1. Short-tail keywords
Short-tail keywords, also known as "broad keywords," are words or phrases consisting of only 1 to 3 words that have a very broad and popular search scope. These keywords usually have high search volume but also come with a very high level of competition.
Example: "car", "buy house", "travel".
Pros: Can generate high traffic and build brand awareness quickly.
Cons: High competition, making it difficult to achieve high rankings without a strong content strategy.
Application: Short-tail keywords are typically used in long-term SEO strategies when you have the capacity to compete with major websites.
2. Long-tail keywords
Long-tail keywords in keyword research are phrases consisting of three or more words that are more detailed and specific. Although they have lower search volumes compared to short-tail keywords, they are generally easier to rank for on search engines.
Example: "buy car on installment with low interest rate", "travel to Da Nang in December", "how to choose a used car".
Pros: Higher conversion rates, lower competition, and users searching for these keywords tend to have a specific intent to purchase or take action.
Cons: Lower search volume and requires more effort to create relevant content.

3. Informational keywords

Example: "how to make pizza", "popular car models", "travel budget tips".
Pros: Easy to attract traffic, allows for rich content creation, and helps build relationships with potential customers.
Cons: Low conversion rates because searchers do not have an immediate intent to buy.
Application: Informational keywords are commonly used in content marketing strategies to help build brand trust and authority.
4. Transactional keywords
Transactional keywords in keyword research are terms users employ when they intend to complete a transaction, such as making a purchase or signing up for a service. These keywords can have a direct impact on revenue.
Example: "buy used car on installment", "sign up for online course", "buy cheap flight tickets".
Pros: High conversion rates, as they can lead to immediate purchasing actions.
Cons: Very high competition, as businesses always target these keywords to attract customers.
Application: Transactional keywords are a critical component of SEO strategies for e-commerce sites or online services, helping to directly increase revenue.
5. Local keywords
Local keywords in keyword research are keywords combined with a geographic location, aimed at attracting users searching for services or products in a specific area.
Example: "used cars in Hanoi", "car repair services in Ho Chi Minh City", "Vietnamese restaurants in Da Nang".
Pros: Helps businesses reach potential customers in a specific geographic area, increasing conversion rates.
Cons: Local keyword optimization may require you to build a specific SEO strategy for each region.
