The Internet as we know it today is a repository of information that is available in all geographic societies. In just over two decades, the Web has moved from a curiosity into a university research, marketing and basic means of communication that infringes on the daily lives of most people in the world. It is accessed by more than 16% of the world in over 233 countries.
If the amount of information on the Web grows, that information is always difficult to follow and use. Compounding the problem is that information is distributed over billions of web pages, each with its own independent structure and format. So how do you find the information you want in one convenient format - and do it quickly and easily without breaking the bank?
Research is not enough
Search engines are a great help, but what they can do the work, and they are struggling to Daily Monitor. For all the power of Google and its parents, can do all search engines to find information and point to it. They are only two or three levels deep into a website to find information and then return URLs. Search engines can not retrieve information from web-depth information available only after completing a form and type of logging, and store it in an appropriate format. Storing data in a format that is desirable or appropriate, after using the search engine to find information, you must have the following tasks for the information you need to record:
Scan the contents until you find the information.
Mark the information (usually by pointing with a mouse).
Switch to another application (such as a spreadsheet, database or word processor).
Stick the information in this application.
Not all copy and paste
Consider the scenario of a company strives for an email marketing list of more than 100,000 thousand names and e-mail to build a public group. It will take more than 28 man-hours, if the person is able to copy and the name and e-mail to paste in one second, equivalent to more than $ 500 in wages alone, no other costs associated with the state. Time required for copying a recording is directly proportional to the number of data that is to copy and paste.
Is there an alternative to copy and paste?
A better solution, especially for companies seeking a broad band of market data available, or competitors on the Internet, based on the use of custom software and web harvesting tools to use.
Web harvesting software automatically retrieves data from the web and picks up where search engines to stop doing the job search engine can not. Extraction tools for automating the reading, copying and pasting needed to gather information for later use. The software simulates the human interaction with the data and the website does, so if the site is in use. Web harvesting software only use the site to find, screen and copy the information needed at speeds much higher, that is humanly possible. Advanced software even able to silently through the site and to gather data without leaving a trace of access.
The next article in this series will provide more details about how the software and some of the myths to discover the web harvesting.
