Yes, you can use Piwik PRO with Google Analytics, or other analytics tools. These tools will not interfere with how Piwik PRO collects and processes data from your website.
When you want to use Google Analytics, we recommend you to install the Google Analytics tracking code using our Tag Manager. For more, see this article.
However, if you’d like to use Google Tag Manager and Piwik PRO Tag Manager, we recommend picking and using one of them. It’s because tags can interfere with each other, especially if you, by mistake, use the same tag in both tools — you better not do that because it may break the tags.
