One of the most popular reasons why search engines are so popular is simply because people are always searching for all sorts of things on the Internet. It doesn't matter if they are looking for website URLs or something in particular. For example, say I want to find the official website for Barnes & Noble (just as a simple example). All I have to do is enter in Barnes And Noble or I could enter in Barnes and Noble plus my zip code and the official website will show up. Pretty simple! Of course adding your zip doesn't really matter for this one but, if you are searching for other things like restaurants, automotive stores, or grocery stores within your vicinity it's a good idea to obviously add your zip code or you could end up on the other side of the state!

Listed below are several different categories (subcategories not included) you may find on a search engine:
Electronic
Recreation
Health
Computers
Science
Business
Real estate
Sports
Education
Politics
Personal-finance

So needless to say everything you could or would need to search for is available, and that wasn't even including all the categories! Also, listed below here are a few of my favorite search engines available online right now!

Find - When I first heard of this engine all I kept hearing was the business side of me going "wow now that's a great domain name" and it is, but more than that it's also a terrific engine where you cannot only just search but you can also find out information about certain subject. For example, if we go to Electronics, we will see a few extra subcategories to choose from such as Bluetooth Headsets, Cellphone Cameras, Cellphones & Home Theatre Systems.

Now if you click Bluetooth you will be given a little summary of what Bluetooth is, how its used, what its functions are and much more. But as said above you can also use this as a search engine, by placing whatever you are looking for in the search box and pressing "find". I did a search for money, and results that were relevant to money showed up. Very easy to use, minimal ads means minimal annoyance, and its got a nice user-friendly template as well!

Wid Explorer - Widexplorer is a whole new way to view, surf, search, organize and share the web! At Widexplorer you can visit multiple websites simultaneously. So in other words its pretty much a meta crawler that doesn't want to be called or classified as a crawler! You can search google, yahoo, msn, ask, dogpile, and a few other search engines all at once.

Ms. Dewey - I don't even use this site to search on, I use it purely to give me a smile upon my face! This is a great SE if you are looking for something to make you smile or you are bored out of your skull and looking to do something interesting, and I suppose it's a good search engine as well! Ms. Dewey is a viral marketing campaign started by Microsoft in October 2006. The Ms. Dewey website is an Adobe Flash-based experimental interface for Live Search.

The interface features a modern-looking cityscape as a backdrop with the character on the left side, while the search results appear on the right. The cityscape backdrop changes depending on the time of day! Ms. Dewey appears to be an interactive search assistant who audibly comments on searched keywords in her own style and makes random actions when idle, including taking props from behind her desk.

These are all some pretty cool search engines in their own ways, try em out and see what you think! You can also look for more of these cool sites by checking out Google! Have fun!
