Search traffic is the number of visitors that come to a website through search engines like Google. It happens when people type in queries and click on links in the organic search results. To boost this traffic, websites need to focus on things like using the right keywords, improving content quality, and building links. Unlike paid ads that give quick but short-term results, good search traffic grows over time with consistent effort. Tools like Google Analytics help track how well a site is doing by showing popular keywords and visitor behaviour.
