Keyword research is a foundational step that helps businesses understand what customers are searching for, choose relevant content topics, and allocate SEO resources effectively. Moz Keyword Explorer supports this process by providing keyword suggestions, potential metrics, and difficulty scores, giving marketers more data to work with before they get started.
This guide explains how to use keyword suggestions and difficulty scoring, and how to interpret the results in a real-world context. The tool can reduce research time, but choosing the right keywords still requires businesses to weigh the data against their goals, search behavior in Vietnam, and the quality of content they can deliver.
What Is Moz Keyword Explorer, and Who Is It For?
Moz Keyword Explorer is a keyword research tool in Moz’s SEO toolkit. Users can enter a keyword or topic to see related suggestions and several metrics that help assess SEO opportunities. Rather than simply compiling a list of queries, the tool helps marketers organize ideas by relevance and potential for further analysis.
The tool is suitable for SEO professionals, content teams, agencies, and business owners who want a more structured keyword research process. SEO beginners can use it to discover how customers express their needs; experienced practitioners can combine its results with data from Google Search Console, website analytics tools, and competitor research.
Keep in mind that data from third-party tools is estimated. Search volume, difficulty, and priority do not guarantee that a page will rank or receive a specific number of visits. Treat these metrics as a basis for comparison and filtering—not as the sole basis for your strategy.
How to Use Keyword Suggestions to Find Ideas
The keyword suggestions feature recommends phrases related to a seed keyword. It’s a useful starting point when a business has a topic in mind but doesn’t yet know how users search for it. Starting with one query, the suggestions can broaden your research to include questions, specific needs, longer variations, or related topics.
A basic workflow typically includes these steps:
- Choose a seed keyword: Enter a phrase that represents a product, service, or issue your customers care about. Start with a topic that is specific enough to be useful rather than an overly broad term.
- Set the right market: Select a language and location if the tool allows it. For businesses operating in Vietnam, prioritize results relevant to the target market and consider how Vietnamese users phrase their searches.
- Review suggestion groups: Browse the suggestions for queries that reflect questions, purchase needs, problems to solve, or ways of comparing options.
- Save and categorize: Add promising keywords to a list, then group them by topic, search intent, and stage of the customer journey.
Don’t choose a keyword simply because it seems popular. Ask what the query reveals: does the searcher want information, a specific brand, a product comparison, or to get in touch and make a purchase? For example, a “what is” keyword often suits an explainer, while phrases containing “price,” “service,” or “provider” may suit a commercial or service page, depending on the context.
Suggestions also need to be checked for relevance. Some phrases may be lexically similar but serve different needs. Grouping them in one article without a well-planned structure can result in shallow content that doesn’t answer readers’ questions.
Understanding Difficulty Scoring and Assessing Keyword Competition
Difficulty scoring estimates how competitive it may be for a page to rank for a keyword. In Moz Keyword Explorer, the difficulty score helps compare opportunities: within the same scoring system, a lower score is generally considered less competitive than a higher one. However, the score does not guarantee that a keyword will be easy to rank for or that a page will reach a particular position.
Difficulty is generally calculated using signals from search results and the strength of competing pages, including factors related to links. Use this metric to put keywords in context rather than treating it as a complete measure. Content that meets search intent, website authority, crawlability, and page experience all affect SEO performance.
When reviewing scores, compare keywords within the same topic group and consider the following factors together:
- Relevance: Does the keyword align with your products, services, and actual business capabilities?
- Search intent: What does the user want to learn, compare, or do?
- Audience potential: Is the query likely to attract the right customers, rather than just generate irrelevant visits?
- Ability to compete: Can your website create content that is better, more in-depth, or more useful than the pages currently appearing in search results?
A high-difficulty keyword may still be worth pursuing if it closely relates to a core service and offers significant business value. Conversely, a low-difficulty keyword that has little relevance to your target customers should not be a priority. Evaluate scores in light of your goals, resources, and timeline.
A Workflow for Combining Keyword Suggestions and Difficulty Scores
To turn data into a content plan, start by generating suggestions from important business topics. Then remove irrelevant queries, group keywords that share the same intent, and note what searchers expect to find. At this stage, the tool can do more than help you find keywords—it can also help shape your website’s topic structure.
Next, compare keyword groups to balance relevance, potential, and difficulty scoring. A new website or one without much in-depth content can start with specific queries that have clear intent and a manageable level of competition. At the same time, businesses should build foundational content around their main topics to broaden coverage and demonstrate expertise over time.
Before producing an article, check the search results for your priority keywords. Look at the types of content that rank, how those pages organize their information, and which questions they answer. This manual review helps confirm whether the tool’s data reflects real search results and prevents you from creating content in the wrong format—for example, writing a how-to article when users primarily need a service page.
Finally, assign a primary keyword and related variations to each specific page. Avoid creating multiple pages that target the same need, as they may compete with one another. After publishing, track impressions, clicks, rankings, and conversions to refine your content. Keyword research is an ongoing activity: new data and changing customer needs may mean you need to update your priorities.
Tips for Using Data Effectively in Vietnam
When researching Vietnamese keywords, pay attention to diacritics, unaccented spellings, abbreviations, and commonly used product names in each industry. Users may express the same need in several ways, but not every variation represents a separate topic. Review search results and actual content before deciding to create another page.
Estimated search volumes may also differ from your website’s actual data and fluctuate with the seasons. Where possible, compare the tool’s suggestions with Search Console, internal search query data, feedback from your sales team, and customer questions. These sources can reveal specific needs that automated suggestions may not fully capture.

Conclusion
Moz Keyword Explorer helps businesses explore topics through keyword suggestions and filter opportunities using difficulty scoring. To get the most from the tool, combine its suggestions with search intent, relevance to your customers, real-world competitiveness, and data from your own website. The tool provides valuable insights, but a strong SEO strategy still depends on quality content, consistent execution, and regular measurement.
