Dealers need the combination of SEO and SEM to best capture leads from their local market. The SEM is needed when consumers type short, broad phrases like "Jeep Dealer" or "Jeep Sale".
SEO is best used for three or more word searches that include any city in their PMA, and beyond as well as they state or their name. Example: "Used BMW X5 Boston" or "NJ BMW Service"
In addition to SEO/SEM they need to have a strategy to clear off Google Page One and Two, any competitive listings and lead arbitrage sites, as you suggest.
Pushing off sites that leach off dealer brand names will increase the leads that come to their website directly.
It's the simplest of concepts but the most misunderstood. Dealers really can own the entire first page of Google results for their name.
It's one of the most satisfying things I do for my clients because their "brand" is what has used the most money to build.
Also, by owning page one, dealers have less immediate impact when a negative review is written about their dealership. Internet Reputation Management (IRM)strategies have a proactive element and owning Page One also assists with IRM.
So, if dealers joined together to achieve a national awareness about owning page one for their brand name, third party lead collectors would most likely see their lead volume drop 25%.
That would send a financial signal to NOT mess with a dealer's brand name.
Has everyone checked their own brand name?
How many spots of the 10 organic listings on Google Page One do you own?
P.S. I practice what I preach. I own my pages for "Brian Pasch" and "Pasch Consulting".
