It depends on how you translated it.
If you just used Google Translate, Google may still be able to ding you through the RankBrain Algorithm's emphasis on user experience.
You have to understand that every single day, millions of pieces of content are published online.
It doesn't matter what niche you're in.
There's going to be a tremendous amount of content in your niche.
People don't have the time to slowly and painstakingly figure out what you're trying to say.
They can and will click the back button the moment they feel that they don't understand what you're talking about.
That's how high the stakes are!
Simply dumping content that is in one language into an English translator and publishing it without any serious attempts at editing or concern for user experience is basically playing Russian roulette.
The only sites that I know that get away with this and make quite a bit of money are sites that have tons of domains.
The reason why they succeed is that most of their domains fail, but the ones that do shine out.
This is called the "survivor bias."
On this forum, you always hear about people who are saying:
"Yeah! I make a lot of money with translated websites."
But you never hear from people who failed.
You never hear about domains that crashed and burned because Google penalized them or just simply failed to send traffic.
Am I saying that translated content has no chance in hell?
No, I'm not saying that.
What I am saying is that translating your content from Polish to English is just the first step.
The second step is to make sure that it's edited properly.
The third step is to pay attention to user behavior and make sure that you're increasing the quality of your content.
And you might want to take the extra step of supplementing the information you have on that page through original research as well as multimedia elements like pictures, diagrams, and videos.
The key is to deliver value.
I understand that people are looking to save money and time.
I understand that.
But if you want to build something that's worthwhile, you have to build it on a solid bedrock of value.
