Top 10 Free Keyword Tools in Taiwan 2026 | Quickly Find Keywords with Good Rankings

What are keywords? Can they affect Google rankings?

Simply put, keywords are the search terms that users enter into a search engine. "steak," "sauerkraut and pork hot pot recipe," and "what is SEO" are all keywords that users might search for.

Google compares the web pages on the internet based on the words entered by the user to see which page best meets the user's needs. When your website content contains correct and valuable "keywords", Google can more easily understand what your content is about, and there is a greater chance that your page will rank higher and be seen by more people.

Keyword Tools 1. Google Search Engine

• The simplest and most intuitive source of keywords
• Free to use

Google is the world's most widely used search engine and arguably the most basic and practical keyword research tool. Its biggest advantage is its ease of use, making it accessible to anyone.
Simply enter your core keywords in the search box, and Google will automatically display the most common related search suggestions in the drop-down menu. These keywords are generated based on the actual search behavior of a large number of users, making them highly valuable. For example, when you enter "healthy eating," you might see related suggestions such as "healthy eating plate" and "healthy eating principles."

Another is the "Related Searches" section at the bottom of the search results page. The keyword strings displayed here are also based on real data generated by user behavior. Although Google does not provide specific search volume data, the keywords that are selected and displayed usually represent a certain level of search popularity.

Keyword planning tool features:

• Try entering partial keywords, such as "recommended," "what is it?", etc., to get broader keyword suggestions.
• The suggested results may differ depending on the device used for the search, such as a mobile phone or a computer.
• Pay attention to the "Others also searched for" section in the search results; these are excellent long-tail keywords.

Large forums like PTT and Dcard are excellent sources for observing the interests of specific communities. You can follow sections related to your industry and observe which topics generate the most discussion and engagement. Similarly, Facebook groups, trending hashtags on Twitter, and discussions on LinkedIn can provide a wealth of keyword inspiration.

News media can help you capture seasonal trends and breaking news topics. When a topic starts to appear frequently in the news, the search volume for related keywords often increases. For example, during the pandemic, the search volume for keywords related to "home workouts" exploded.

Advanced techniques for using keywords

Having mastered the keyword tools above, how can we further utilize these keywords? For example, by adding "long-tail keywords," we can use more specific terms to attract genuinely interested potential customers. This not only makes them easier to find but also increases conversion rates. Simultaneously, we should delve into the users' search intent: are they simply looking for information? Do they want to know where to buy? Or are they already ready to place an order? Tailor your website content to their needs and add clear calls to action (CTAs) to make it easier for them to take the next step, such as placing an order, leaving a message, or contacting us.

Observing which keywords competitors are using and how they create website content is actually a great way to learn quickly. Learn what they do well and incorporate it into your own website. If you can also learn from relevant foreign websites and apply it to your own website before your competitors do, you will have an even greater advantage.

Common mistakes in keyword planning

When optimizing website content, user experience should always be the top priority. Subtly integrate keywords without being overtly obvious, ensuring a natural tone. Adjust content or add long-tail keywords based on user needs to truly resonate with them. It's recommended to use multiple keyword tools for cross-validation for more accurate data. Finally, don't forget to update keywords regularly; continuous content optimization is key to improving website ranking.
