• Increased Efficiency: Perform routine tasks with a single click, saving you valuable time.
• Instant Analysis: Get immediate insights into a webpage’s SEO elements without leaving the page.
• Reduced Costs: Many bookmarklets provide functionalities similar to paid tools, making them a cost-effective solution.
• Customization: You can create your own bookmarklets or modify existing ones to suit your specific needs.
• Browser Compatibility: Bookmarklets work across most modern web browsers, including Chrome, Firefox, and Safari.

How to Create Your Own SEO Bookmarklet with AI

While the list above is extensive, you might have a unique, specific task you want to automate. Thanks to advancements in AI, you no longer need to be a JavaScript expert to build your own tools. Here’s a simple, step-by-step guide on how to create a custom SEO bookmarklet using a tool like ChatGPT.

Step 1: Define Your Bookmarklet’s Function

First, clearly identify the task you want to automate or the data you need to access. What is the goal? For example, you might want a bookmarklet that extracts all hreflang tags from a page, checks for specific schema types, or highlights all external links that are not nofollow.

Step 2: Use ChatGPT to Generate the JavaScript Code

Next, describe your desired function to ChatGPT in plain English. Be as specific as possible.

Example Prompt:

“Write the JavaScript code for a browser bookmarklet that finds all schema markup scripts (application/ld+json) on the current webpage, parses the JSON, and displays it in a new, cleanly formatted browser tab.”

ChatGPT will then generate the necessary JavaScript code for your bookmarklet.

Step 3: Create and Save Your New Bookmarklet

Finally, turn that code into a functional bookmarklet in your browser.

1. Make sure your bookmarks bar is visible.
2. Right-click on the bookmarks bar and select “Add page…” (or similar wording depending on your browser).
3. In the Name field, give your bookmarklet a descriptive title (e.g., “View Schema”).
4. In the URL (or Address) field, paste the complete JavaScript code generated by ChatGPT.
5. Click Save.

Your new custom bookmarklet will now appear in your toolbar, ready to use with a single click!
