Parsing is usually used when you need to quickly collect a large amount of data. It is performed using special services - parsers. In this article, we will look at the purpose for which parsing can be used, what it allows you to find out about your competitors, and whether it is legal. We will also look at how to parse data step by step using one of the tools. Reading time 17 minutes What is parsing Ways to use parsing What competitors can learn through scraping Is it legal to scrape websites? Parsing stages How to parse data How to protect your website from scraping conclusions What is parsing Parsing is the process of automatically collecting data and structuring it. Special programs or parser services “bypass” the site and collect data that meets a given condition. A simple example: let’s say you need to collect contacts of potential partners from a certain niche.
You can Fax Lists do this manually. You will need to go to each site, look for the “Contacts” section, copy the phone number into a separate table, etc. So it will take you five to seven minutes to visit each site. But this process can be automated. You set the sampling conditions in the parsing program and after some time you get a ready-made table with a list of sites and phone numbers. The advantages of parsing are obvious - if you compare it with manual collection and sorting of data: you receive data very quickly; you can set dozens of parameters to compile a sample; there will be no errors in the report; parsing can be configured with a certain frequency - for example, collecting data every Monday; many parsers not only collect data, but also advise how to correct errors on the site. There are quite a lot of parsing programs on the Internet.
They can be in a “cloud” or a “box”: the cloud version is SaaS , you will need to register and work with the service directly in the browser; boxed version is a solution that you need to install on your computer and work with it in the program window. In both cases, you pay for access to the parser for some time. For example, a month, a year or several years. Ways to use parsing The scope of parsing can be reduced to two purposes: analysis of competitors in order to better understand how they work and borrow some approaches from them; analysis of your own site to eliminate errors, quickly implement changes, etc. Parser capabilities, parsing, parsing program An example of what one of the parsers can offer for searching, fixing errors and boosting SEO We regularly use the Ringostat blog parser. For example, when you need to find images that for some reason do not have the Alt attribute assigned. Search engines consider this an error and may lower the ranking of a site that has many such illustrations.
