Back the the OG - I am still a firm believer that the website that the customer was on should get the lead. They spent the time/money to get that customer there - need a shot at that reward.
We've created a bit of a monster there so not as simple as the site gets the lead. This is true on our "forced OEM DDC sites" but our main traffic sites (WP) are our market-level sites. There are up to three stores represented in each of those. All Used are on all sites and all New are on all sites as long as that Make is in the market. For instance every market has at least one Ford store so all sites have all New Fords. Lincoln, NE market doesn't have a Kia point so there are no new Kia's listed on that market site, etc. Here are the rules we have built in:
For example on andersonoflincoln.com, it represents Anderson Ford Lincoln of Lincoln North, Anderson Mazda of Lincoln, and Anderson Ford of Lincoln South. The rules on our native forms for Used are:
1. If a Used car is at a Lincoln, NE store, the lead selection defaults to that store but the shopper can select the other two manually if they desire to work with another store in Lincoln.
2. If a Used car is at a market outside of Lincoln, NE, the shopper has to select "Choose your dealer" from one of the three dealers in Lincoln, NE.
For New on native forms:
1. If a New Ford is at a Lincoln (city not brand) store it'll default to that store but the shopper can select the other store in Lincoln, NE if they so choose.
2. If a New Ford is outside of Lincoln, NE store, it forces the shopper to pick one of the two Ford stores in Lincoln, NE
3. If they pick a new Mazda or Lincoln (brand), it only goes to the Mazda store or the Ford/Lincoln point with no other option.
We just replaced UpStart/Prodigy with Accelerate as the DR on the sites so working to code the same rules on their 3rd party script.
