Hello, I have a list of about 450 links to different paying surveys companies. The companies are list randomly. So I need the list to be resorted as follow: 1- To Categorize the companies by the types of survey it offers: For example: ** Satisfaction subcategory: Customer Satisfaction Product Surveys Service Evaluation ** Marketing subcategory: New Product/Concept Testing Focus Group Recruitment Website Conference Feedback Hardware/Software **Human Resource subcategory: Employee Evaluation Job Satisfaction Training Evaluation **Services subcategory: Hotels/Resturant Retail Health Care B2B Travel ** Academic/Research subcategory: Course Evaluation Training **Community subcategory: Social Personal Demo/Psychographics The above is just an example. 2- Check and Remove any duplicate links or different links that lead to the same exact site. 3- Check any non-wroking or broken links. Thank You.
