It’s common for sites developed with React to inject content into the DOM when a user clicks or hovers over an element—simply because the library makes that easy to do. This isn’t inherently bad, but content added to the DOM this way will not be seen by search engines. If the content injected includes important textual content or internal links, this may negatively impact: How well the page performs (as Google won’t see the content). The discoverability of other URLs (as Google won’t find the internal links). Here’s an example on a React JS site I recently audited. Here, I’ll show a well-known e-commerce brand with important internal links within its faceted navigation. Affiliate marketing whatsapp number list has a simple premise. Just like Batman and Robin, vendors team up with affiliate marketers for mutual gain, making it a win-win for many business owners. However, a modal showing the navigation on mobile was injected into the DOM when you clicked a “Filter” button. Watch the second <!----> within the HTML below to see this in practice: Gif of modal showing the navigation on mobile was injected into DOM Solution Spotting these issues isn’t easy. And as far as I know, no tool will directly tell you about them. Instead, you should check for common elements such as: Accordions Modals Tabs Mega menus Hamburger menus You’ll then need to inspect the element on them and watch what happens with the HTML as you open/close them by clicking or hovering (as I have done in the above GIF). Suppose you notice JavaScript is adding HTML to the page. In that case, you’ll need to work with the developers. This is so that rather than injecting the content into the DOM, it’s included within the HTML by default and is hidden and shown via CSS using properties like visibility: hidden; or display: none;.
