Did you know the first link you see when you search for a brand is most probably a landing page advertisement? And to be specific, these advertisements are product landing pages!
Wait, wait! Let's start from the beginning.
You go to Google and look for a brand "XYZ". A dozen web pages may resemble what you searched for, but you're more likely to click on the first page the search engine showed.
Based on the information you see on this page, your willingness to buy from that brand may change.
