What could be causing the issue of a custom js code not displaying properly on Google indexed pages for a Webflow landing page? Is it possible that there is a bug in the code?

There could be multiple reasons why a custom JS code is not displaying properly on Google indexed pages for a Webflow landing page. Let's explore some potential causes and solutions:

1. JavaScript Execution on Page Load: Ensure that the custom JS code is executed after the page has finished loading. Sometimes, JavaScript code may depend on specific HTML elements to be present on the page, and if those elements are not fully loaded when the code runs, it could result in errors or unexpected behavior. You can wrap your code in an event listener that triggers when the page has finished loading, such as `window.addEventListener('load', function() { ... });`.

2. Markup Conflicts: Custom JS code might interfere with the existing HTML code or other JavaScript libraries on the page. Be cautious of any conflicting or overlapping JavaScript code that could result in errors. Inspect the developer console for any error messages that could provide insights into the cause of the issue. Check for variable naming conflicts, function collisions, or jQuery conflicts, if applicable.

3. Asynchronous Code: If your custom JS code relies on external resources (e.g., images, scripts, APIs), ensure that it is appropriately handling asynchronous operations. It's crucial to use callbacks, promises, or async/await functions to ensure that the code waits for the required resources to be available before executing dependent logic.

4. SEO Optimization and Crawling: Ensure that your Webflow landing page is correctly optimized for search engines. If the page is not optimized, Google may not accurately index or display the JavaScript content. Make sure your page metadata (title, description, headings) and structured data (Schema.org markup) are well-formed.

5. Googlebot Scrutiny: It's possible that Googlebot, the web crawler used by Google, may not execute or index certain JavaScript elements on a page. Googlebot has become more adept at rendering JavaScript-based websites in recent years, but it still has limitations. To better understand how Googlebot interprets your page, you can use the Google Search Console's URL Inspection tool to see a rendered version of your page and any errors or warnings related to JavaScript execution.

Regarding the possibility of a bug in the code itself, it's challenging to determine without seeing the specific code in question. However, it's essential to thoroughly test and validate your code's functionality outside of the Webflow environment. Run your code in a local development environment or a code sandbox like CodePen or JSFiddle to isolate any issues that may be specific to Webflow.

Remember to check for compatibility with different browsers, validate syntax, and verify any API integrations or third-party libraries used. Additionally, consider seeking assistance from Webflow support or the Webflow community forums, where experts can provide more specific insights based on your code and implementation details.
