Sadly, the answer is no. Google+ engagement has dropped a lot. There is no way to group responses. They don’t want to make it easy for you to write one response and send it to a large number of people. Krista recommends that you answer them individually, but encourages you to create a set list of responses to the things you’re constantly responding to. We have a document filled with responses to questions we’re asked repeatedly. It’s easy to copy and paste from it, instead of recreating the same answer over and over again. Another thing you could consider is to adding an FAQ section on your site. The more information that’s publicly available the better for your potential clients and you, as you won’t have to manually answer them time and time again. For every one person who asks, there are likely hundreds who don’t but still wonder.
