For companies that have little budget, but whose goal is to rank high in Google, using SEO is ideal. SEO increases the value of your business and passively brings in customers courtesy of its position in Google. SEO is basically free, unlike SEA. For companies that have lots of time but little budget and don’t have the urge to get short-term results, SEO is guaranteed to work.
SEO ensures a sustainable marketing strategy. This is because it involves the structural optimization of various pages. For this reason, you only see its effect in the long run. Patience is a fine thing.
