Should You Target Vietnamese Keywords With or Without Accents?

Quick summary: Businesses should prioritize SEO for keywords with diacritics because Google recognizes standard Vietnamese better and better, results with diacritics are favored in search, and they feel more trustworthy to users. On top of that, once a keyword with diacritics reaches the top, its no-diacritics variants usually climb along with it. Optimize no-diacritics keywords as an add-on only when you target young users who type fast on mobile, the gaming or tech sectors, or when Google Search Console data shows a significant share of no-diacritics traffic.

“Should you do SEO for keywords with or without diacritics?” is a question every business has asked when it wants to optimizing the website for SEO. The strategy you choose not only decides your ranking on Google but also directly affects whether customers can find and trust your brand. In this article, MONA Media will analyze search habits, answer whether to go with or without diacritics, and suggest the best direction for your business.

Why keyword choice matters in website SEO

Why keyword choice matters when doing website SEO

Keyword is the “bridge” between a business and its customers, helping you reach people who want to buy or use a service. With the right Keyword SEO strategy, a business can steer its content, improve its Google rankings and gain other clear benefits such as:

  • Attract a large volume of quality traffic to your website.
  • Increase the chance of purchases or sign-ups and improve the conversion rate.
  • Cut costs running Google Ads, saving the business a lot of time and resources.

How Vietnamese users habitually type keywords without diacritics

Compared with many other languages, Vietnamese has keywords both with and without diacritics. Many people prefer no-diacritics keywords for messaging and searching the internet because they are faster and more convenient to type, save time and still keep the meaning.

This habit comes from several causes:

  • Faster typing: On phones in particular, users often drop diacritics to save time when searching.
  • Long-standing habit: Many people got used to typing without diacritics from their first days on computers or mobile devices, so it is hard to change.
  • Strong Google support: The search engine still returns accurate results for both keywords with and without diacritics.
An example of how Vietnamese users type keywords

For example, when searching for SEO services in Ho Chi Minh City, a customer might type “dịch vụ SEO TPHCM” or quickly type “dich vu seo TPHCM”. Both lead to accurate results for SEO service providers. But that does not mean Google rates no-diacritics keywords highly. Recognizing this search habit is the key to a more precise SEO strategy.

Should you prioritize keywords with or without diacritics?

When it comes to whether to do SEO for keywords with or without diacritics, many businesses are unsure which is the wiser choice. In reality, both matter, but to build a lasting brand and get the best SEO results, businesses should prioritize SEO for keywords with diacritics for these reasons:

  • Thanks to updates in Google's algorithms, this tool is getting smarter at recognizing Vietnamese, so results for keywords with diacritics are usually shown more accurately and given priority.
  • Users tend to click on results that show full diacritics, because they feel more trustworthy and professional.
  • When you optimize SEO for keywords with diacritics, your website also benefits when ranking for no-diacritics keywords (thanks to the semantic relevance Google understands).

Of course, SEO for keywords without diacritics should not be ignored either, since there is still a group of users who search this way, especially on mobile devices. Depending on the project, target audience and budget, a business can flexibly choose the SEO strategy that fits. You can also use keyword research tools to speed up keyword selection for your SEO project.

Why should you do SEO for keywords with diacritics?

The decision to do SEO for keywords with or without diacritics can affect the results of your SEO website strategy. With over 10 years of SEO experience, MONA sees investing in SEO for keywords with diacritics as the smart choice, giving businesses a solid base for long-term growth.

Google rates results with diacritics highly and shows them first

Google gives priority to keywords with diacritics

Whether users search with or without diacritics, most results on Google are still content written with diacritics. This shows that Google values websites that use standard, clear language. With diacritics, information is easier to read and understand and avoids confusion about meaning, which is important for keeping customers and raising the conversion rate.

SEO for keywords with diacritics pulls up the ranking of no-diacritics keywords

Another advantage is that when you optimize keywords with diacritics well, the no-diacritics variants usually rise along with them. In many cases, SEO for no-diacritics keywords even reaches the top faster because competition is low. So instead of running two separate campaigns, a business only needs to invest in well-written content with diacritics to benefit from both groups of keywords.

Keywords with diacritics build more credibility with customers

Do SEO for keywords with diacritics to make your website more credible

Vietnamese users may search with no-diacritics keywords to save time, but when they read, they want content with diacritics that is clear and professional. If a website overuses no-diacritics keywords in its articles, users find it annoying and think less of the brand's credibility. For a business, professionalism has to show in how it communicates, and SEO for keywords with diacritics is a plus that builds customer trust.

Vietnamese with diacritics is increasingly favored in search behavior

Vietnamese is rich in nuance, and many words change meaning when diacritics are dropped. That is why the trend of searching for and reading content with diacritics keeps growing. If your business still wonders “should we do SEO for keywords with or without diacritics?”, the answer is clear: focus on keywords with diacritics to match user habits, while keeping content clear, easy to understand and friendlier to Google.

Google puts user experience first

Do SEO for keywords with diacritics because Google puts user experience first

Google keeps improving to deliver the most relevant and useful search results to users. It measures experience through time on page, shares and engagement. Content written in standard Vietnamese with diacritics is rated higher because it is friendly to readers and fits Google's direction. In other words, the more you focus on SEO for keywords with diacritics, the more likely your website is to be shown first.

When should you do SEO for keywords without diacritics?

Although the focus is always on SEO for keywords with diacritics, in the following cases optimizing no-diacritics keywords as well will help your website's SEO perform better:

  • Optimize for fast-typed queries on mobile: Typing fast without diacritics on smartphones is very common, especially among young users. That is why a business can add SEO for no-diacritics keywords to capture this search volume.
  • Focus on niche markets or specific audiences: In tech, gaming, fashion or young communities, no-diacritics searching shows up more often. This is a chance to widen your keyword coverage without competing directly with the keywords that have diacritics.
  • Brand or product keywords from abroad: For international brand names and specialized products or services, users often type without diacritics. Optimizing this variant too helps your website reach real demand.
  • Widen your reach: Instead of focusing only on keywords with or without diacritics, a business should combine both to cover how customers search, especially in full-scope SEO.
  • Based on Google Search Console data: If traffic from no-diacritics keywords makes up a significant share, that is a sign you should consider adding no-diacritics keywords to widen your strategy.
