1.1. About WordPress Content Crawler

WordPress Content Crawler is a WordPress plugin that can crawl (scrape, grab, retrieve) content from almost any site existing in the Internet (See: Can I get content from X site?). It uses CSS selectors to locate and retrieve the content in the target web page’s source code. CSS selectors are very easy to learn and very helpful to locate the information in the target site. The plugin also comes with a Visual Inspector that you can use to click to an element to find its CSS selector. The tool is also capable of finding a CSS selector that finds items similar to the one you click. This feature is quite helpful if you want to retrieve, for example, all URLs in a category page. For more information, please refer to its documentation.

The plugin has over 200 settings to enable you not just to retrieve content but also retrieve them in the way you want. For example, you can change HTML of the elements existing in the source code, remove the elements, change attributes of the elements, exchange the values of two attributes of an element, find and replace anything in the source code, assign certain elements to a short code and use them in the templates, and many more. You can refer to Site Settings Page section to learn more about all of the settings of the plugin. You can also read Common Options section.

The plugin works by using WP-Cron. This feature of WordPress lets plugins and themes define certain jobs to be triggered at certain times. These jobs are run in the background. The plugin defines jobs to automatically crawl, recrawl (update), and delete posts. By this way, the plugin is able to run in the background and do all of its work automatically. Hence, a working WP-Cron is a requirement of the plugin. To learn more about all requirements of the plugin, please refer to Requirements section.

Here is a video tutorial that explains the plugin’s working logic, along with some CSS knowledge. This video is a good starting point to understand the plugin.
