With the EmbedReviews plugin, you can now send your customers to leave reviews directly on your Google location or Facebook page.
​
Go to your 'Widgets' and 'edit' one of your widgets (screenshot below):

Next, on the left-hand side, you can click on the 'header' options, and scroll down to the 'Button source type' option where you need to choose the source type to redirect customers either to your Facebook or Google location or EmbedSocial (save the reviews in your EmbedSocial account) of the widget source(screenshot below)
​

In the end, click 'Save' in the top-right corner as stated in the screenshot above.

Now, every time your users click on the 'Leave a Review' button they will be redirected to your Facebook page, Google location, (depending on what you select) to leave the review there.
