The tool you use to find things online.
I’ve never understood why “they” — those mysterious naming-guys — called this an engine. Makes it sound so complicated* and locomotive-like. Nevertheless, this is a very simple term. Think how time-consuming it would be to go through the Internet’s index like you do in the back of a textbook. So geniuses (I’m not kidding. They ARE geniuses.) came up with a way to sort the Entire Internet into huge indexes that will allow you to search the whole thing in miliseconds.
Try to imagine the sheer number of words online, then consider the number of languages there are on Earth. Also take into account the fact that there are new pages going online constantly all over the planet. It’s truly amazing.
There are three main search engines:
There are a lot of other search engines, but these are the most common.
Some facts about search engines:
– Google is the most popular search engine
– they all allow you to pay for advertising on them — usually you pay by the number of clicks you get on your site’s address
– BUT! they list your site for free if you don’t advertise
– you can tell the search engine NOT to index your site if you don’t want it out there for the world to find
– search engines display the websites that are MOST relevant to what you searched. So, if you call it Scotch tape and don’t find anything (unlikely), try cellophane tape.
*Search engines ARE complicated, because they use algorithms while most of us have trouble balancing checkbooks, which use subtraction (at least in my case).
