What Is SEO?
SEO (Search Engine Optimization) is the process of improving a website’s visibility in search engine results pages (SERPs) such as Google.
The goal of SEO is to increase organic traffic by helping search engines understand your content and determine when it should be shown to users.
When someone searches for:
- Best digital marketing agency
- SEO services near me
- How to improve Google rankings
Search engines analyze millions of pages and rank the most relevant results. SEO helps your website become one of those results.
