10 solutions to monitor competitor prices. Overview of tools and services.

Web scraping tools are designed to retrieve, collect and share any open information from websites. These resources are needed, when any data from the Internet, needs to be quickly spun and stored in a structured form. Site scraping is a new data entry method, that does not require re-entry or copying. For example, this service (https://xmldatafeed.com) uses parsing to monitor competitor prices for retailers.

This kind of software searches for information under user control or automatically by selecting new or updated data and storing it in a way that the user has quick access to it. For example, using parsing, you can collect product and price information from the Amazon website. Below we’ll look at web-based data extraction tools and the top ten services that can help collect information without having to write special program codes. Parsing tools can be used for a variety of purposes and scenarios, and consider the most common uses that may come in handy.

Data Collection for Market Research

Web-based data mining services will help you keep track of where your company or industry is going in the next six months, providing a strong foundation for market research. Parsing software is able to retrieve data from multiple data analytics providers and market research firms, and then bring that information into one place of reference and analysis.

Retrieval of contact information

Parsing tools can be used to collect and organize data, such as mailing addresses, contact information from various websites and social networks. This allows you to create convenient contact lists and all related information for your business – information about customers, suppliers or manufacturers.

With site parsing tools, you can create offline use and storage solutions by collecting data from a large number of web resources (including StackOverflow). In this way, you can avoid dependency on active Internet connections, since the data will be available regardless of whether you can connect to the Internet or not.

Searching for jobs or employees

For an employer, who is actively looking for candidates to work in his company or for a job seeker who is looking for a particular position, parsing tools will also become indispensable; with their help, you can set up data sampling based on the various filters, that come with it and effectively obtain information without routine manual searches.
