Once installed, go to your search area and search for Canary. You can do this even if you have regular Chrome installed on your computer. #COMMAND LINE FOR MAC TO START CHROME DOWNLOAD#To begin, you want to download Chrome Canary. #COMMAND LINE FOR MAC TO START CHROME INSTALL#Let’s take this step by step… Step #1: Setup Google Chrome Canary Install Google Chrome Canary There is a lot but (I promise!) this is tedious more than difficult and you will like the results. #COMMAND LINE FOR MAC TO START CHROME MAC#While more advanced functionality is available by running Puppeteer or Selenium, the following instructions will walk you through how you can run a headless version of Google Chrome directly from the command line on Windows (sorry Mac users – I’m not a Mac user myself, but most of this should work similarly within Terminal). So, I am going to assume you aren’t a developer and that you aren’t familiar with Node.js. The best way to understand a headless browser is to run a headless browser yourself. How to Run Headless Chrome from the Command Line While there are many similarities between Puppeteer and Selenium, one big difference is that Puppeteer works only with Chrome while Selenium supports multiple browsers, including Firefox, Edge, and Safari. By default, Selenium is not completely headless but can be configured to operate that way. If you are familiar with Node.js, you can run headless Chrome with Puppeteer relatively easily.Īnother option is Selenium, which is a popular solution for automated browser testing. #COMMAND LINE FOR MAC TO START CHROME CODE#Puppeteer is a Node.js library and, as a result, you are writing commands for the headless browser in JavaScript code which is considerably easier than writing those commands in a command line. However, the options for what to run from the command line can be limited.Īs an alternative, and for more functionality, you can run headless Chrome using Puppeteer. This can be a bit more straightforward as a place to begin. One option is to run headless Chrome directly from the command line interface (see next section for details). There are a few different ways you can run headless Chrome. This is what Googlebot uses to crawl your website and if you want to test how Googlebot will see your website, this is what you should be using to test your website. You can execute and run Google Chrome without the graphical user interface. There are a number of headless browser options, but the one I’ll focus on is the headless version of Google Chrome. Headless Browser Options: Puppeteer, Selenium, Command Line You could use a headless browser to fetch the content from the competitor’s website and then write a separate program to grab the price information out of that content. For example, you might want to extract pricing information from your competitor’s website. Headless browsers can also help you extract information from websites that don’t offer an easier method for getting that information. Beyond SEO, headless browser testing can also be used to mimic user behavior at a larger scale to confirm everything works as intended within the website. By testing in this way, you can confirm that there aren’t any issues that would prevent Google from being able to access the content on that page. For SEO, testing with a headless browser allows you to see a page similar to how Googlebot sees it. Headless browsers can also help you test websites more easily, including for SEO purposes. Google’s bots crawl the website using a headless browser and feed the content found via the headless browser into their programs that evaluate and rank websites in search results. Why would you want to use a headless browser and browse the web without the GUI? Using a headless browser allows you to programmatically access website content and feed the content from the website into other programs. This more closely mirrors what can be seen in a traditional GUI browser and allows automated tools to replicate what humans see. While there are other ways of fetching a website’s code, a headless browser is able to execute JavaScript, load CSS files, and load font files. Instead of navigating visually through the website, you navigate the headless browser via code or via a command-line interface.
