Having videos on your auto dealer website has been shown to increase website leads, and when done with video search engine optimization (VSEO), helping your site climb the search engine result pages. If your dealership has videos on your website, you should have those videos uploaded to your own dealership YouTube channel.
Popularity: YouTube is the world's largest video search engine (and the second largest search engine) and growing every single day. People all over the world use it to find videos, so if someone searches for a vehicle that your dealership sells, don't you want a video from your dealership to show up?
Timing: Like most search engines, YouTube tends to give older entries a little extra edge when returning search results. The sooner you create your channel and upload videos, the better.
Cost: YouTube is free. Aside from the time cost of uploading (though it's possible your auto dealer website or video provider will do this for you), YouTube has no financial cost. This means you get all of this exposure without an additional marketing cost.
Blended Search: Google, Bing and Yahoo are integrating mixed media (images, news, videos, etc) into their search engine result pages, so having your VSEO dealership videos on a separate domain can provide an additional link on Google’s results page for any search relevant to your dealership brand or your inventory.
