SEO is the practice of optimizing a website to improve its organic visibility in search engine results pages. It involves creating quality content, building links, and leveraging the latest trends and technologies. Google Ads is an online advertising platform where businesses can pay to have their ads displayed on Google's network of websites and apps. Ads are displayed based on keywords that the advertiser selects, so they're more targeted than organic traffic. The goal of both is to increase website visibility and reach customers, but SEO is a longer-term strategy, while Google Ads are more immediate.
