Secret Hidden Web Search Engines

Nearly 90 percent of the web is off limits if you aren't searching using Hidden Web search engines. If you want to find more than just what shows up on Google, then you need to know your way around the Hidden Web.


What are hidden web search engines? They are search engines that allow you to search across the web for sites that store data which is not easily spidered by Google or other surface web engines. These major sites can only look at text or labels within the text. They can't search databases, and they can't search the content of video, audio or other materials on the Web. This kind of non-searchable material forms the vast majority of what's available on the Web.


If you use a hidden web search engine though, you are using specific search engines designed to retrieve results from sites with that specialized, difficult to find data.

Are these search engines really "secret"? No not really, but it takes some digging to find them. In addition, you can find different ways to search the Web even using the surface web search engines to target better results. Some search engines for example focus on only governmental databases. Some focus on providing documents instead of HTML web pages. Knowing which engine will get you the results you need is part of the hidden web of search engines.

There are specific hidden web search engines for government research, academic research at universities, corporate research from R&D departments, not to mention all of the documents and data stored by local and state governments, smaller colleges, private organizations and foundations, and much much more. Generally, most of this can be found on the hidden web, and much of it can be used by any person or business for research and business purposes.

Why Hidden Web is Better Than Google

If more than 90% all information is only accessible through the Hidden Web, if you are searching for things on Google, you may only be getting 10% of the possible results on the Web. Only by using the Hidden Web will you find even more results, comprising the bulk of everything stored on the Internet.

Sites like Google rely on HTML text based searching. However they can't search database results, images without ALT tags, the content of documents in PDF format, and much much more. All of this is stored on the Web, but without a hidden web search engine, you will not easily find all of the results you need.

Instead, you can locate specific documents in formats like PDF, word processors, or image files by using specific search engines that can access those materials. The way to find these resources is by getting to know the hidden web better.

Also known as the deep web or the invisible web, the hidden web contains thousands of search engines that focus only on their little corner of the world. Then there are search engines that aggregate other search engines, which means that once you have a list of specialty search engines, you can combine them to access information across all of them. There are even software products that help you search across multiple deep web search engines.

When you're looking for information that is authoritative and you need it for a business purpose or for academic research, sometimes Google results can be disappointing at best. Filled with many websites that are no responsive to your need, these results can waste a lot of time. If you need industry information for marketing purposes, for example, there are many government databases that provide detailed statistical data, but which you must access through sources not normally listed on Google. It is to your great advantage to find hidden web resources that will help you get the authoritative data you need.
