(Note: Google states that using JavaScript to change or remove the robot’s meta tag might not work as expected. Use this if you wish to prevent Googlebot from indexing a page or its following links. Use a meaningful status to tell Googlebot if a page should not be crawled or indexed, as well as if a page has moved to a new URL.

Googlebot has some limitations regarding which APIs and JavaScript it supports, so it is important to make sure your code is compatible. Javascript can be used to set or change the meta description as well as the title. Describe your page with unique titles and snippets.Next, the guide suggests some simple, basic tips to improve your site’s SEO - with links to more detailed resources: Indexing - Googlebots use that rendered HTML to index the page in search results.Rendering - During this time, once Googlebot’s resources allow, a headless Chromium ( running Chrome in a headless/server environment) renders the page and executes the JavaScript.Crawling - Googlebot fetches a URL from the crawling queue and checks if you allow the page to be crawled.So, unless your website is incredibly barebones, it can probably be considered a web app.įirst, Googlebot processes JavaScript web apps in three phases: crawling, rendering, and indexing. These have typically been in the realm of “web applications” in the past, but they carry a lot of benefits for standard websites as well. But many web services and coding frameworks are now bringing functionality like pre-fetching links (so linked pages can load faster) and only reloading content that changes between pages (again - loading pages faster!).
You may not think of your website as being a “web app” with things like logging in or user profiles. Well, the line between the two is becoming much more blurred. I thought we were talking about web pages and not apps. How does Googlebot process JavaScript web apps?

Javascript is a client-side programming language which helps developers make dynamic and interactive web pages by implementing custom client-side scripts. The guide covers how Google Search processes JavaScript, and the best practices for improving JavaScript web apps for Google Search.īut wait - why is processing JavaScript different than HTML and CSS?
