How to Translate Your Shopify Store via DeepL and Google Translator API

When looking at translation methods offered by LangShop, our clients may wonder what the pro translation is: it’s definitely neither an agency (human) translation, nor automatic translation. 

In reality,  you must be more familiar with pro translation even than with translation agencies. You might have used it at school or college, when traveling to faraway countries or getting acquitted with a stranger-foreigner. Still not clear enough? Maybe the term Google Translate or DeepL Translator will help?

Yeah,  pro translation is a process when the pro translation drivers, like Google or DeepL, translate your store content from one language to another without human involvement.

But don’t associate it with poor translation!

Contrariwise, with the time pro translation drivers have been developed and taught. So now, in comparison with other translation methods, it occupies the middle position in all parameters: it’s a quite fast, good quality, mid-priced translation method. 

Pro translation doesn’t take much time, as it is performed by the software, the quality is not affected by different drivers usage (as in automatic translation) – you choose only one to perform the translation. Also the fact that contrary to standart translation drivers, pro translation ones are based on neural machine learning, which provides better translation results, should be taken into account. Besides, to enable translation, you’ll need a pro translation API key, which is available for the translation driver subscribers and, consequently, requires additional fees, but these expenses are nothing compared to agency translation ones. 

So, for those who need a good and quick translation, pro translation is a perfect matchup. The only point to decide is what engine to use. Well, let’s figure it out together!


Google Translate

Google Translate is the world’s best known machine translation engine. It works on the basis of recurrent neural networks, a form of artificial intelligence which can be thought of as a replication of the nervous system of a human brain.

Google Translate

The original database for Google Translate drew heavily on Europarl Corpus, the translated texts from European Parliament documents. Additionally, it uses a huge number of different texts to teach the system to perform more accurate translations. When the recipient enters the word or phrase, Google Translate generates a translation proposal and searches for the patterns in hundreds of millions texts translated by human translators. After that it chooses the most appropriate one based on word combination. 

Google Translate supports about 109 different languages and dialects. The engine can translate multiple forms of text and media, including static texts, speech, media, websites, etc. The website translation is performed via Google API, which is available for users with paid accounts on the Google Cloud Platform.

DeepL Translator

Released in 2017, DeepL claimed to steal Google’s limelight. Same as Google, DeepL uses neural networks for translation. However, you shouldn’t think the drivers are the same. Unlike Google, DeepL Translator uses convolutional neural networks, which are applied to analyze images. It helps DeepL to translate long text better, especially for European language pairs.

Deepl Translator interface

Based on Linguee, an online dictionary, DeepL has developed its own way of translating texts, which contributes a lot in its fast growth and amazing translation results. 

DeepL Translator supports 26 languages and dialects, mostly the European ones. DeepL can translate texts, documents and even a website via API, accessible with paid DeepL Pro subscription.

DeepL vs. Google Translate

When choosing a pro translation driver for your online store, you should take into account its language diversity, translation quality, the security of the translated content and pricing. Let’s compare the engines on these parameters together!

Language diversity

As mentioned above, Google has an impressive number of supported languages and beats DeepL in this category. However, we should mention that though it supports 109 languages, it doesn’t mean it translates all language pairs. Still the supported language pairs reach the number of hundreds of thousands language pairs. 

So if you want to translate your Shopify store into Africaans or Zulu, Google Translate is exactly what you need.

Translation quality

It’s hard to give a single conclusion on which engine provides more accurate translation, as it differs depending on the language pair. However, multiple researches admit DeepL translations to be better, especially for European language pairs. 

Thus, in 2018 a Canadian linguist ran a research setting potentially challenging French-language sets to estimate the accuracy of translation. The result showed that DeepL Translate showed better translation of idioms, general questions and negative sentences. The researcher claimed that DeepL creates more natural-sounding translations, and copes better with slang and idioms.

Translation security

Most sources agree that DeepL provides better data security: it meets EU data protection regulations and provides end-to-end encryption when transferring the data. Google, in their turn, claims that the content sent via API will not become available to the public and is not shared with third parties.


As the API key is available only for certain plans users, let’s compare these plans. Google fees depend on required features and the number of characters used and start from $10 per month. DeepL offers an unlimited number of characters translated and offers its services starting from $22.99 per month.

Now with all this information you can make a data-driven decision of which pro translation driver suits your business needs better.
