How to Add Sticky Sidebar Widget in Blogger

 Sidebar widgets disappear when users scroll. Sticky widget = 300% more ad views + email signups.

In this tutorial, you'll make any Blogger sidebar widget sticky. Follow along and you'll boost AdSense CTR + conversions in 2025.

Step 1: Why Sticky Sidebar Widgets Make More Money 2025

Visible ads = clicked ads. Hidden widgets = zero earnings.

1. AdSense CTR: Sticky 300x600 ad gets 2.5x more clicks than static sidebar ad
2. Email signups: Sticky opt-in form converts 3x better
3. Affiliate links: Sticky "Top Picks" widget stays in view while user reads
4. User experience: Sticky TOC helps users navigate long posts

Step 2: Add Sticky CSS to Blogger Theme

1 code block makes any widget sticky. No JavaScript needed.

1. Blogger → Theme → Edit HTML → Ctrl+F → Search ]]></b:skin>
2. Paste this code ABOVE ]]></b:skin>:

/* Sticky Sidebar Widget 2025 */
.sidebar .widget {
position: -webkit-sticky;
position: sticky;
top: 20px; /* Distance from top when stuck */
}
/* Stop sticky before footer */
@media (min-width: 980px) {
.sidebar {
align-self: flex-start;
}
}
/* Disable sticky on mobile */
@media (max-width: 768px) {
.sidebar .widget {
position: relative !important;
top: auto !important;
}
}

Step 3: Make Specific Widget Sticky Only

Don't want all widgets sticky? Target 1 widget by ID.

1. Layout → Find widget you want sticky → Click Edit → Look at URL
2. URL shows: widgetId=HTML3 → Copy the ID
3. Use this CSS instead. Replace HTML3 with your ID:

/* Sticky One Widget Only */
#HTML3 {
position: -webkit-sticky;
position: sticky;
top: 20px;
}
@media (max-width: 768px) {
#HTML3 {position: relative !important;}
}

Step 4: Best Sticky Widgets for Blogger Revenue

Widget Type	Why Sticky	AdSense Policy
AdSense 300x600 ad	Highest CTR. Stays in view 100% of scroll	Allowed. Max 1 sticky ad per page
Email opt-in form	3x more subscribers vs footer form	Allowed. Must not overlap content
Table of Contents	Users jump between sections easily	Allowed. Improves UX
Affiliate product box	Stays visible during entire review	Allowed. Add nofollow links

Step 5: Fix Sticky Widget Overlapping Footer

Common problem: Sticky widget covers footer. Fix it with this.

1. Theme → Edit HTML → Find <div class='sidebar'> or <aside>
2. Add this wrapper DIV around your sidebar content:

<div style="display:flex;align-items:flex-start;">
  <div class='main-content'>...your posts...</div>
  <div class='sidebar'>...your widgets...</div>
</div>

3. Adjust top distance: If you have sticky header, change top: 20px; to top: 80px;
4. Test: Scroll to bottom → Sticky widget must stop before footer starts
5. Mobile test: Open on phone → Widget should NOT be sticky. Mobile sticky = bad UX

Bad practice to avoid: Making 3+ widgets sticky. They stack and cover content. Google penalizes. Max 1 sticky element per page.

Important: AdSense policy: Only 1 sticky ad allowed. Must not cover content or navigation. Use "AdSense → Ads → Overview → View ad examples" to check compliance. If your theme is old, sticky may not work. Switch to Contempo or Soho theme. Test in Chrome, Safari, Firefox.
