What Is SEO?

The goal is simple: get your content in front of the people searching for it.

A Brief History of SEO
SEO has come a long way since the early days of the internet.
- 1990s: SEO started with the first search engines like AltaVista and Yahoo.
- 1998: Google changed the game with its PageRank algorithm.
- 2000s: SEO evolved to include keyword optimization, meta tags, and backlinks.
- 2010s: Major algorithm updates (like Panda and Penguin) focused on content quality and user experience.
- 2020s: AI, voice search, mobile-first indexing, and user intent became SEO priorities.
How Search Engines Work
Search engines like Google follow a 3-step process:
- Crawling – Bots scan websites for new and updated content.
- Indexing – Content is stored and organized in the search engine’s database.
- Ranking – Algorithms decide which content is most relevant for a search query.
Key Components of SEO
Understanding the major parts of SEO is crucial to building a successful strategy.
