SEARCH ENGINE:
A search engine is a software program that helps people find the information they are looking for online using keywords or phrases. Search engines are able to return results quickly even with millions of websites online by scanning the internet continuously and indexing every page they find.
A search engine is a software program or system designed to help users find information stored on the internet or within a specific database. Let’s delve into the details of how search engines work:
- Crawling: Search engines employ computer programs called crawlers to find publicly available information on the internet. These crawlers scan the web, creating a list of all available websites. They then visit each website, analyze its HTML code, and understand its structure, content type, meaning, and creation/update date. Ensuring that your website is accessible to crawlers is crucial for search engine optimization. If crawlers cannot find your content, your website won’t receive any ranking or search engine traffic.
- Indexing: Once the crawler identifies information, it needs to be organized, sorted, and stored for later processing by the ranking algorithm. Search engines maintain an index containing essential details about web pages, such as:
- Title and descriptionType of contentAssociated keywordsNumber of incoming and outgoing linksOther relevant parameters needed for ranking
- Ranking: Ranking determines the position of your website in search engine results. Here’s how it works:
- Relevance: Search engines evaluate how well a page matches a user’s query. They consider factors like keyword relevance, content quality, and user intent.
- Authority: Search engines assess a page’s authority based on the number and quality of incoming links. Pages with more authoritative links tend to rank higher.
- User Experience: Factors like page load speed, mobile-friendliness, and overall user experience impact rankings.
