What is SEO?
SEO (Search Engine Optimization) is the practice of optimizing your website to rank higher in search engine results pages (SERPs). When people search for products, services, or information related to your business, you want to appear prominently.

In 2026, SEO is not about tricking search engines—it's about creating the best possible content for users while making it easy for search engines to understand.
The Three Pillars of SEO
Modern SEO rests on three foundational pillars:
- Technical SEO: Ensuring search engines can crawl, index, and understand your website
- Content Quality: Creating valuable, relevant content that satisfies user intent
- Authority: Building trust through backlinks, reviews, and brand signals
Key Takeaway:
SEO drives organic traffic—visitors who find you through search without paying for ads. This traffic tends to have higher intent and better long-term ROI than paid channels.
