Why Is SEO Important?
SEO is important because:
- Over 90% of online experiences start with a search engine
- Websites on page one get most of the clicks
- SEO brings free, long-term traffic
- It builds trust and credibility
- It improves brand visibility
- It increases sales, leads, and conversions
Unlike ads, SEO traffic doesn’t stop when you stop paying.
How Search Engines Work (Simple Explanation)
Search engines work in three main steps:
1. Crawling
Google uses bots (called crawlers) to discover new and updated pages.
2. Indexing
Google stores and understands the content of pages.
3. Ranking
Google shows the best pages in search results based on relevance and quality.
SEO helps your site perform better in all three steps.
