What is SEO?
SEO (Search Engine Optimization) is the process of improving a website so that it appears higher in search engine results for relevant keywords.

For example, if someone searches:
- Best Web Design Company

Google displays websites it considers the most helpful and trustworthy. SEO helps your website become one of those results.
