The first step for any search engine is to apply ranking algo to all its pages.

• A. True
• B. False
• C. It depends on the engine
• D. They perform crawling first

Answer: (B)

Search engines follow a crawl–index–rank flow. They begin by crawling the web to discover pages and fetch their content. Next, that content is indexed so it can be searched quickly. Only when a user submits a query does the engine use its ranking algorithm to order the relevant pages from the index. Ranking isn’t applied to all pages upfront; it’s applied during retrieval for a specific query. So the statement is false. The standard process starts with crawling.
