Blogger (Blogspot) is still used by millions of blogs worldwide. Adding a floating CTA button is simple using Blogger's built-in theme HTML editor. Design your button, export the code, and paste it into your theme — it'll appear on every page of your blog.
Why Add a CTA Button to Blogger?
Blogger blogs often rely on AdSense and affiliate links for revenue, but those are embedded within content and easy to scroll past. A floating CTA button gives you a persistent, high-visibility touchpoint for your most valuable action — whether that's a product recommendation, an email list signup, or a link to your YouTube channel. Since Blogger doesn't have a plugin ecosystem, custom code injection via the theme editor is the most reliable way to add this functionality.
Step-by-Step Instructions
Design your CTA button
Open the CTA Button Generator and customize your button using the visual editor. Pick colors, position, animation, hover effects, icon, and font. The live preview updates in real time so you see exactly what your visitors will get.
Export your code
When you are happy with the design, click "Get Code" to export a clean HTML + CSS snippet. The code is lightweight, has zero dependencies, and works on any website.
Open the Blogger theme editor
In your Blogger dashboard, go to Theme > click the dropdown arrow next to "Customize" > select "Edit HTML". This opens your full theme code.
Paste the code before the closing body tag
Scroll to the bottom of your theme HTML and find the closing </body> tag. Paste your CTA button code just before it.
<!-- Your CTA button code goes here -->
</body>Save and preview
Click the save icon in the theme editor, then visit your blog to confirm the floating CTA button appears on all pages.
Best Practices for Blogger
Back up your theme HTML before editing — Blogger's undo functionality is limited, and a backup lets you restore quickly.
Paste the code right before the closing </body> tag, not inside any widget or section divs, to avoid layout issues.
Use a descriptive link for the button (your email list, a product page) rather than linking to another blog post that's already accessible via navigation.
Test the button on Blogger's mobile view, as Blogger uses a separate mobile template that may require the code to be added separately.

Open the GeneratorFrequently Asked Questions
Will the button appear on every blog post?
Yes. The code is added to your theme's HTML, which wraps all pages including individual blog posts, the homepage, and archive pages.
Is this free on Blogger?
Yes. Blogger allows full theme HTML editing on all accounts for free. No paid plan needed.
Will the button show on Blogger's mobile version?
If your blog uses the default mobile theme, the button may not appear on mobile. Go to Theme > Mobile and select "Desktop" to use your desktop theme (with the button) on mobile devices.
Can I add the button to specific posts instead of site-wide?
Yes. Instead of editing the theme HTML, you can paste the code directly into an individual post using the HTML editor view within the Blogger post editor.
