Don’t neglect your website when it comes to publishing your video. Use it on any page that’s relevant. If you’ve got a product video, for instance, you’ll want to embed the video on your homepage, as well as your product or ecommerce pages. If you publish a blog post about your product, include the video! If you’ve got an FAQ page with questions about your product, include the video there, too!
The ad auction process takes place every single time someone enters a search query into Google. To be entered into the ad auction, advertisers identify keywords they want to bid on, and state how much they are willing to spend (per click) to have their ads appear alongside results relating to those keywords. If Google determines that the keywords you have bid on are contained within a user’s search query, your ads are entered into the ad auction.
After that, you need to make a choice about how to construct an online presence that helps you achieve that goal. Maybe you need to set up an e-commerce site. If you’re interested in publishing content to drive awareness and subscribers, look into setting up a blog. A simple website or landing page with a lead capture form can help you start developing your brand and generating traffic. A basic analytics platform (like Google Analytics, which is free) can help you start to measure how you are tracking towards your initial goal.
