The Automotive vertical seems to get more worked up over Google changes than some of the other verticals. My sense is that's because some of the SEO folks that concentrate on automotive speak with a little more hyperbole. Everything isn't a crisis and no, we aren't all under attack
We do like to get worked-up. It breaks the day up
Many of us bought-in to DealerRater and supported it in a major way. Some put all their eggs in the DealerRater basket with "certified" monthly fees and possibly purchasing advertisements. It seemed to be a good investment that played to a dealer's competitive drive as long as it got to where most of the eyeballs were: Google.
I still believe DealerRater is a viable option, but the dynamic is different now. Like Chip said, you still have the ability to display your DealerRater reviews prominently in various digital properties. Through DealerRater you can still make your good reputation known, but it now takes some extra work on the dealer's part (assuming most just wanted it for Google).
Yes, it is tougher to get a consumer to engage on Google over DealerRater. The simple answer is one that was proposed in this thread earlier, and is one I hope many engaged in from the start:
Utilize your CRM or ILM tool. If it has the ability to differentiate customers by their email address, it is fairly easy to setup a special template that goes to people with GMail addresses, and direct the rest of your customers to review sites that are easier to engage with.
At the end of the day I think there are too many review sites. I don't blame Google for making these very logical changes (especially if Congress backs this move up with new legislation
...speculating). It dilutes their brand and disrupts their relevancy when illegitimate reviews are displayed prominently.
Now, if Google can just get their Places (not reviews) information correct and deemphasize sites that play into that equation.
