Why do Local "5 pack" results vary between showing Google+, Google+ and website address

[Ron_McCabe]

I had a client ask me a good question. When they pull up a search result they show up at the top but only with a link to their G+ page. Other competitors show their web address and G+ page.  Why are these results different in the same search group? Is there a way to ensure the web address shows up?

The obvious problem would be that their website address hasn't been verified and linked to their Google + profile... Linking them together in GWT and Analytics would help too. After checking those things I'd check other settings, like use Google + as site.
