SEO (Search Engine Optimization) is the way to make a website show up in search results on pages like Google, Bing, DuckDuckGo, and others. SEO looks at the words on a page, site design, and links from other sites. It's about how fast your page load, works on a phone, and things like meta tags. Meta tags give a short hint to a search engine about what a page shows. The title and description are important. You add alt text to images so a bot can read them.
How Search Engines Work?
Search engines find and rank pages in three steps:
- Crawling gathers pages from across the web
- Indexing sorts and stores page data
- Ranking orders pages by match
Crawling is like a library helper that walks the shelves and notes every book. It is kind of like when you ask a friend to walk down a street and list each shop sign. This step helps a search engine know what is out there. A crawler follows each link on a page to discover new pages. It does this until it maps a whole site structure.
Indexing is like adding each book to a catalog with its title author and subject. The index notes the main words and other markers so the engine can find a page in no time. The engine stores a record of each page so it can search fast.
Ranking
Ranking comes next. Ranking is like a helper giving the closest match at the top based on what you ask for. It uses factors like page words links and load speed. Each factor has a score and all scores add to a page rank. A page with many links joins the top list. This process runs all the time to keep results fresh. It sends users to pages that match what they ask.
