SEO vs. SEM: Which is the Best Strategy for Your Website?

In the world of digital marketing, SEO (Search Engine Optimization) and SEM (Search Engine Marketing) are two of the most powerful strategies for increasing a website’s visibility. However, although they are often mentioned together, SEO and SEM are two different approaches that can benefit different types of businesses depending on their goals, budget, and available time. Below, we explain the key differences between SEO and SEM, and how each can be beneficial for your business.

1. What is SEO?
