Search engine optimization, or SEO. It is a branch of digital marketing that has expanded quickly in recent years. Simply said, SEO is the technique of marketing your company and putting your brand in front of the billions of people that search online every day using search engines like Google and Bing. Furthermore, SEO allows you to take use of search engines' marketing potential without having to pay for advertisements, even if search engines like Google do provide paid advertising options. When you purchase Facebook advertising, you effectively annoy someone who was idly scrolling through their news page. People notice your Instagram postings as they scroll through hundreds of other images of friends when you post something. They might pay attention to you, but they might not. But when someone uses a search engine, they are typically already seeking for something. This is the result of SEO. Putting oneself in front of people's inquiries and providing an answer is the goal of SEO.
