Spiders - A spider is a program that visits Web sites and reads their pages and other information in order to create entries for a search engine index.

Robots - Robots.txt is a text file that webmasters create to instruct web robots (typically search engine robots) how to crawl pages on their website. In practice, robots.txt files indicate whether certain user agents (web-crawling software) can or cannot crawl parts of a website.

Crawlers - A crawler is a program used by search engines to collect data from the internet. When a crawler visits a website, it picks over the entire website's content (i.e. the text) and stores it in a databank.
