Search engines track how long a user spends on your website. This is known as bounce rate. If a user searches for “Seattle Air Conditioner” and goes to a website that is not relevant and goes back and searches again this is very bad for your website. This is telling the search engines that people are not finding what they searched for and they will subsequently list it lower. But if people stay longer on your site and explore it more by clicks this is telling the search engines that they did their job right and therefore will rank your site higher.
