AdSense Sticky Ads Policy Basics for Small Blogs
AdSense sticky ads policy basics for small blogs: desktop sticky rules, one-sticky-at-a-time, and how that differs from anchor ads—Sticky-Then-Policy.
AdSense sticky ads can be allowed—and still get small blogs in trouble. Sticky-Then-Policy is the high-level placement risk map: what Google’s sticky rules require, how that differs from anchor bars, and when a custom sticky sidebar is a bad first move.
This page is not AdSense anchor ads basics (top/bottom Auto overlay UX). It is not ad density policy (content vs ads balance). It is not Auto ads vs manual units (control model). It is not mobile layout ads basics (phone-first in-page slots). Early-link those owners; do not treat this URL as a second anchor guide.
Direct answer: Sticky ads are permitted in AdSense if you follow Help’s technical rules (≤300px width examples, no overlap, one sticky in view, desktop-only sticky implementations). Anchors are a separate Auto format. Stacking sticky + desktop anchor in the same viewport is a common policy foot-gun.
Disclosure: Educational policy overview. We do not invent RPM lifts or “safe sticky CTR” numbers. Confirm every rule in official Google AdSense Help before you ship CSS.

Sticky vs anchor in plain language
Publishers often say “sticky ads” for anything that follows the scroll. Google’s docs split the idea:
| Label | What it usually means | Where to learn more |
|---|---|---|
| Sticky ads (Ad formats FAQ) | Fixed/sidebar-style units with size, overlap, and desktop rules | This page + Ad formats FAQ |
| Anchor ads | Top/bottom dismissible Auto ads overlays | Anchor ads basics + About anchor ads |
| Side rail (Auto settings) | Sticky side rails on wide screens via Auto controls | Auto ads settings |
If your question is “should I turn on the bottom bar?”, open the anchor owner. If your question is “can I position: sticky a 300×250 in the sidebar?”, stay here.
Sticky policy checklist from Help
From Google’s Ad formats FAQ — Sticky ads (re-check live text before coding):
| Rule (summary) | Why it bites small blogs |
|---|---|
| Width 300px or less (728×90 called out as not allowed) | Wide leaderboards glued to the side fail the FAQ |
| Must not overlap / underlap content, nav, scrollbars, or other ads | Sticky headers + sticky ads = collision |
| Attributions and ad content must stay visible | Clipping or partial covers are not “clever UX” |
| Ads scroll into and out of view; no pop-in/pop-out tricks | Fade/slide gimmicks can look like discouraged manipulation |
| Move on the vertical axis only — no cursor-following floaters | Fancy parallax sticky is a red flag |
| Render smoothly without stutter | Heavy JS sticky can fail the “reasonable rate” bar |
| One sticky visible in the viewport at a time | Dual sidebars / sticky + sticky = fail |
| Sticky implementations are for desktop only | Copying sticky CSS to mobile layouts breaks the rule |
Also keep ad code modification in mind: covering content with ads, or hiding units improperly, is a separate failure mode.
One sticky in the viewport
Help is explicit: only one sticky ad may be visible at a time. Mirrored left+right stickies, or two stickies stacked on one side, are not allowed.
Practical implication for Auto users:
- If you run a custom sticky sidebar, review whether desktop anchors or side rails still fire in the same viewport.
- Prefer turning off competing sticky overlays on wide screens rather than “hoping Google sorts it.”
- After changes, scroll a long post on a real desktop width—not only the AdSense preview thumbnail.
Desktop only — do not sticky the phone
The FAQ states sticky implementations are for desktop and ads should not be sticky on tablet or mobile-optimized versions—even if the page is not fully mobile-optimized.
That is why this page early-links mobile layout ads basics: phone UX is a different job. On mobile, lean on formats Google documents for small screens (including anchors when you choose them), not a CSS sticky port of your desktop sidebar.
Small-blog decision: enable or skip
| Situation | Sticky sidebar? | Safer first move |
|---|---|---|
| Short posts, narrow theme, sticky header already | Often skip | Manual or Auto in-content only |
| Wide desktop column with clear 300px rail | Maybe later | Confirm one-sticky rule vs Auto overlays |
| Still learning Auto vs manual | Skip custom sticky | Auto vs manual |
| Density already aggressive | Skip | Ad density basics |
| Want a dismissible bottom bar | Not this job | Anchor ads |
Sticky sidebars are a layout + policy project. They are not a required step to “make AdSense work.”

Mistakes that raise policy risk
- Treating anchor and sticky FAQ as the same toggle.
- Sticky 728×90 or other wide units on the side.
- Sticky ad under a sticky site header that covers attributions.
- Sticky left and sticky right “for symmetry.”
- Sticky CSS that stays fixed on mobile breakpoints.
- Chasing sticky revenue before fixing density and readable layout.
FAQ
Are sticky ads allowed in AdSense?
Yes. Google’s Ad formats FAQ states sticky ads are permitted when you follow listed technical requirements—width limits, no overlap, one sticky visible at a time, desktop-only sticky implementations, and smooth scroll behavior. Confirm the live Help article; menus and wording can change.
Are sticky ads the same as anchor ads?
No. Anchor ads are an Auto ads overlay format that stick to the top or bottom of the viewport and are dismissible. Sticky ads in the Ad formats FAQ usually mean fixed sidebar-style units with their own size and desktop rules. Use the anchor ads owner for bar UX; use this page for sticky policy risk.
Can I run a sticky sidebar and a desktop anchor at once?
Help requires only one sticky ad visible in the viewport at a time. Mirrored or parallel sticky units are not allowed. If you keep a sticky sidebar, treat overlapping desktop anchors as a policy risk and review Auto ads settings carefully.
Are sticky ads allowed on mobile?
The sticky-ads FAQ rules say those implementations are for desktop only and ads should not be sticky on tablet or mobile-optimized versions. Anchor ads are a separate format that can serve on mobile. Do not copy desktop sticky CSS onto phones—see mobile layout.
What widths are allowed for sticky ads?
Help allows formats with width of 300px or less (examples listed include 160×600, 300×600, 300×250, 300×50, 120×600). A 728×90 is called out as not allowed for sticky. Re-read the live FAQ before you code.
Is this the ad density policy page?
No. Ad density owns “more ads than content” risk. This page owns sticky/fixed placement rules and how they sit next to anchors.
Should small blogs enable sticky sidebars on day one?
Often no. Many short editorial layouts gain more risk than revenue from custom sticky CSS. Prefer conservative Auto vs manual setup, then add sticky only when desktop width and content column leave clean clearance.
Where is official Help?
Ad formats FAQ (sticky section), About anchor ads, Auto ads settings, placement policies, and ad code modifications. Always re-open Help in your account language.
Policy first, then placement
Sticky-Then-Policy means: read Help’s sticky rules, separate them from anchor overlays, keep one sticky in view on desktop only, and skip custom sticky CSS until density and layout are calm. Revenue experiments that ignore the FAQ are not a growth plan—they are a review risk.
