So sorry I've been swamped and could not circle back to this one. You'll see why I put it off. I usually do a pretty deep dive when I research and it takes time. Several issues.
Colan is right this likely has a lot to do with the site optimization which could use some help. But I think the Place page could possibly have a ranking penalty and here's why.
I searched the exact phrase in the title tag, knowing that should come up fairly high.
(FYI poor title tag IMO too.) So this is basically the only phrase he probably ranks on page 1 for and no one is going to search for this phrase.
"
Auto Insurance Services Company Las Vegas"
So he ranks #6 in organic BUT is disconnected so does not rank in blended. (He also has one of those weird new empty map markers instead of being up in the blended with link to G+ page. We still don't know for sure what's up with those new markers.)
But what I DO know is some of the main reasons listings get disconnected from sites in blended. And it's usually either duplicate confusion, NAP inconsistency, or Place page penalty.
In this case a few things are wrong.
DUPE: Nationwide Insurance - About - Google+
Which is a violation and also causing or contributing to the disconnect.
But it's odd because it has owner description and his pic, BUT it's showing as unverified. Did you have this claimed and just recently release it?
DUPE IN MAPMAKER:
Google Map Maker I don't have time to dig through and try to understand all the history but recently it had a similar name as your current listing "Frantwan Leblanc Agency - Nationwide Insurance"
And in mapmaker YOUR listing used to have the name of some different agent - Jeff Wilson Agency.
DESCRIPTION PROBLEMS
“The Frantwan Le Blanc Insurance Agency Specializes In Auto, Home, Life and Commercial Insurance. At Nationwide We Are On Your Side For All Of Your Insurance Needs. Call Today For A Free Quote!”
Best practice don't repeat business name and don't keep repeating keywords. Insurance is repeated 3 times and all the other category keywords are repeated too. Google also does not like it when every word is capped. So I'd change that too.
NAP PROBLEMS - ADDRESS ON PLACE
"Frantwan Leblanc Insurance Agency" "7595 West Washington Avenue #140" "(702) 236-0367" ONLY 1 MATCH IN GOOGLE. I stripped off ave and #140 to see if due to different citations formatted differently, then only 2 matches.
So then I searched for the address format that's on the site. (the 2 should match.)
"Frantwan Leblanc Insurance Agency" "7595 W Washington Ave" "(702) 236-0367"
25,600 MATCHES - that's a little better. Then add in #140 and it's 3250, still not bad.
BUT I don't know if I'd risk changing address AND also don't know how address is listed in dash.
It may be correct there and diff live.
Plus there have been so many previous name changes on this listing it looks like.
So this is pretty much a scrambled mess. Beyond the scope of this forum for me to do much more than I already have. I can only do so much here as I need to spread my volunteer free time helping a few here AND and bunch of people on the Google forum, plus try to help on my consultants with their client issues.
But keep asking questions as you have them and hopefully Colan and others can help and I'll pop back in for short Qs but need to go work on client cases now.
