In doing some research for a client, I came across this piece and I couldn’t agree more:
Syncing Your Google Plus and +Local Pages: Plusses and Minuses | Mihmorandum: “Having gone through the process, the benefits of the extended descriptions and links you can add to a sync’ed +Local page, and the early-adopter ability to promote ONE single Plus presence for your business seem pretty substantial.”
We’ve helped a few clients verify their address with the snail mail postcard-from-Google method and it’s been painless every time with nice benefits in search engine results.
So, if you’re in need of having your physical address linked to a high ranking result in your serp’s, we highly recommend going through the process.
