Too much duplicate text?

[anonimas]

Last December we started losing traffic to our website https://www.spec.lt (This is in Lithuanian).
The thing we did was to every single company page we added QR Code.

For example: https://www.spec.lt/imone/onninen-uab (at the bottom of this page).

We added some text that goes with it. As you can see here http://imgur.com/a/beaYm
The only difference between those texts is the company name. Can this be the reason why google reduced our positions ? (We didn't lose any of traffic in categories/search/articles - only in company pages).

A lot of companies that are new or bancrupt have little to no text at all. Except for this text about QR code, like here for example - https://www.spec.lt/imone/mazoji-bendrija-transportas-2017

Can this be the reason? Or any other on page errors that you see.
Thank you

Anyone alive to help?

Hey there! I took a look at this--it is definitely possible that search engines might have flagged this QR code & copy to your pages as being duplicative content, but it doesn't seem like a large enough issue to have caused a continuous downward trend to your traffic.

Are there any other things you've done to your website since December, or things you did around the same time as this QR code addition?
