You would get more response here if you include more information about the project. Who is "we"? What is the business model? Are there really more then 100000 car dealership sites? How did you find them? Are you allowed to use the photos and infos from those sites?
"We" = the MotoMiner team. We wanted to create a real web search engine (like Google) but for cars. Other sites let you search on their listings which are acquired through manual import/export processes. Some of these sites also require dealerships to pay them money to be listed on them. MotoMiner has no entry barriers. Its automated processes to monitor/mine the web for vehicle classifieds are free and yield a more comprehensive dataset to search on.
Other listing sites will not let the buyer/visitor navigate to the original vehicle classified page on the auto dealership's website. They do this so they can capture the buyers information and resell it to the seller/dealer or make dealers subscribe to their services. This process frustrates both buyers and sellers. MotoMiner's visitors are able to search on the data and navigate directly to the original page to which the vehicle was found. The process is more transparent and the buyer can deal directly with the seller.
Yes, there are over 100,000 car dealership websites. Some of them are inactive, some redirect, some sellers have multiple websites with the same cars. MotoMiner indexes data from all of them and we run de-dupe & cleaning processes on it.
MotoMiner's objective is to help buyers find cars more efficiently. MotoMiner also helps the sellers (often car dealerships) by getting them more exposure for free. We index a handful of data points per page (we don't scrape the page and reshow it as our own). These indexed data points are used so visitors can search on them and find the vehicle detail page they'd want to go to.
As to how we identify what websites, what pages to index, how we extract data points... those are trade secrets.
Our business model is like other search engines. MotoMiner presents a new and improved way that buyers want to search for cars. We will allow for sellers to be able to promote their vehicles in an unobtrusive way. When you search Google, the first 1-3 results may be an Ad that is pertinent for what you searched on. MotoMiner can do the same. For instance, if you searched on a Ford F-150 near zip code 12345, a local Ford dealership may be paying to promote their vehicles and so their Ford F-150's may show up in the first 1-3 results.
