The single most effective way to boost AdSense revenue is to ensure your highest-earning ad unit remains visible for the longest possible time. A standard sidebar disappears when a user scrolls down, resulting in lost impression opportunities.

This **Fixed (Sticky) Sidebar Code** uses a small snippet of CSS to keep the main sidebar widget—where your most profitable AdSense or affiliate block resides—"stuck" to the screen. This dramatically increases visibility, click-through rates (CTR), and your overall session earnings.

Why This Fixed Sidebar Code Boosts Revenue

  • **Maximized Impressions:** The ad unit is constantly in view, generating maximum impressions per user session, which directly increases AdSense earnings.
  • **Higher CTR:** A visible ad is a clickable ad. The constant presence in the user's peripheral vision leads to a higher click-through rate.
  • **Improved User Experience (when implemented correctly):** Unlike aggressive pop-ups, a well-placed sticky sidebar is non-intrusive, providing a smooth reading experience while maintaining visibility.

The CSS Code (Sticky Position)

This code should be added to your theme's main CSS section.


/* Replace 'YOUR_WIDGET_ID' with the actual ID of your sidebar widget */
/* Example: #HTML2, #BlogArchive1, etc. Use your browser's inspect tool to find it. */
#YOUR_WIDGET_ID {
    position: sticky;
    top: 20px; /* Adjust this value to set the distance from the top of the screen */
    z-index: 10; /* Ensures the ad unit stays on top of other elements */
}

/* IMPORTANT: Ensure the parent container of the sidebar has no overflow:hidden or display:flex applied. */

/* Media Query to disable sticky on mobile, which is often a poor UX practice */
@media screen and (max-width: 768px) {
    #YOUR_WIDGET_ID {
        position: static !important; /* Forces standard scrolling on small screens */
    }
}

How to Implement in Blogger

  1. **Find Widget ID:** Right-click on your sidebar ad unit and use your browser's "Inspect Element" tool to find the unique ID (e.g., `HTML1`, `BlogArchive2`).
  2. **Code Insertion:** Go to **Theme (테마)** -> **Customize (맞춤설정)** -> **Add CSS (CSS 추가)**.
  3. **Copy and Customize:** Paste the CSS code above, making sure to replace **`#YOUR_WIDGET_ID`** with your actual widget ID (e.g., `#HTML2`).
  4. **Test:** Verify that the ad unit scrolls down with you on desktop, but remains static on mobile screens (768px wide or less).
