Lots of popular search engines available on the Internet such as Google, Yahoo, ASK, MSN, Altavista, AOL, Gigablast, Fast, NetscapeSearch, Snap etc..
Search Engine has an agent program commonly known as a web crawler / web spider / web robots, etc.. This crawler duty to seek and to index (save / collect information) millions of websites with automatic and structured (such as a web domain, title, keywords, description, content, etc.) into the database. He said, each could crawler to index more than 3 billion its website per month (howr big its database).
