What Does Your Plumbing or HVAC Business Need to Do?
If Your Business Already Had a Verified Google Places Page:
Google+ Local pages are generated automatically for any business that had a prior Google Places page. As of right now, you should still manage your listing through the Google Places platform.
However, if you do not have a Google+ account, you should setup an account in order to really take your listing to the next level.
If Your Business Did Not Have a Verified Google Places Page:
If you did not have a verified Google Places page, you can still claim your company listing via the Google Places platform. If you did not have a page at all, you can also setup a Google+ Local page by signing up to Google’s social networking site, Google+ (or Google Plus).
Either way, be sure to complete your listing as much as possible for the best results; use your real address and a local phone number, fill out all fields, carefully incorporate targeted keywords in the “description,” and upload as many pictures as possible to fully optimize your listing.
Once your page is verified, start using the many tools located within Google+ that will eventually be responsible for helping you gain even more exposure. This includes joining circles, encouraging your customers to leave reviews, posting updates about your business, and more.
