Over the years, Google has experimented with a number of services including Google Places for Business and Google+ Pages Dashboard to manage business information. If you have previously registered for these services, you should appear automatically within Google My Business. However, it is worth checking that your enterprise is there and that the information is up-to-date.
I have recently updated my SEO e-book. I wrote the original version several years ago and during that time I have noticed that quite a few directories have disappeared. I imagine that some of them have merged with each other; however, I have a feeling that quite a few of them just couldn’t compete with Google.
