What is SEO and Why is it Important?

- SEO offers access to a massive, global audience (nearly 4 billion Google users as of 2019).
- SEO is a major industry due to its effectiveness at helping businesses get discovered.
How Search Engines Work
- Search engines act like libraries, storing copies of web pages.
- Google uses crawlers ("spiders") to discover and index publicly available web pages.
- Crawlers follow hyperlinks from known URLs to collect information for the search index.
Google’s Ranking Process
- Google ranks results based on relevance, not just keyword matching.
- The ranking algorithm uses hundreds of signals, with frequent updates.
- Key ranking factors include backlinks, search intent, and content depth.
Key SEO Ranking Factors
- Backlinks: Links from other websites act as "votes" of trust and authority.
- Search Intent: Content must match the underlying goal of a search query (e.g., informational vs. transactional).
- Content Depth: Content should thoroughly answer the searcher’s query, providing necessary context and detail.
