Only about 2–5% of first-time website visitors convert. The other 95–98% leave. Some aren’t ready. Some got distracted. Some compared you to a competitor and haven’t decided yet. Remarketing is how you stay in front of them while they’re still deciding.
For small businesses with limited budgets, remarketing is often the highest-ROI campaign type you can run — because you’re paying to re-engage people who already know you exist.
What Remarketing Is and How It Works
Remarketing (also called retargeting) shows ads to people who have previously visited your website. When someone visits your site, Google’s tag (placed in your site’s code) adds them to an audience list. When they browse other websites in Google’s Display Network, or use Google Search, or watch YouTube, your ad can appear.
The audience is warmer than any interest or demographic targeting. These aren’t people who might be interested — these are people who were interested enough to visit your site. You’re paying to continue a conversation that already started.
Google Ads supports remarketing across three campaign types:
Display remarketing: Banner ads shown to past visitors across Google’s network of millions of websites. This is the most common form — someone reads a news article and sees your ad in the sidebar.
Search remarketing (RLSA): Bid adjustments for past visitors when they search on Google. You don’t necessarily show ads only to past visitors — you adjust your bids upward when a past visitor is searching for your keywords. If someone visited your site last week and is now searching for your core service, bid 20–30% higher to prioritize winning that auction.
YouTube remarketing: Show video ads to past visitors on YouTube. Best suited for businesses where video demonstration adds value and budgets are $2,000+/month.
Setting Up the Google Ads Remarketing Tag
Before you can run any remarketing, you need the Google Ads remarketing tag (or the equivalent via Google Tag Manager) installed on every page of your site. This tag fires for every visitor and records them as an audience member.
If you’re already running Google Ads, check whether your global site tag is installed — it may already be creating audience lists automatically. Go to Tools & Settings → Shared Library → Audience Manager → Audience Lists to see what audiences exist.
Google requires an audience to have at least 100 members before ads can show. For small businesses with modest site traffic, this means you may need 2–4 weeks of traffic accumulation before your first remarketing campaign can run.
Audience Segmentation: Who to Retarget
Not all past visitors are equal. A visitor who spent 3 minutes reading your pricing page is not the same as someone who bounced from your homepage in 10 seconds.
Segment your remarketing audiences by behavior to improve efficiency:
All website visitors: Your broadest audience. Use this for general awareness remarketing. Keep bids lower — many of these visitors had minimal engagement.
Visitors to specific pages: Anyone who visited your pricing page, services page, or a specific product page. These are higher-intent visits. Bid higher and use more direct conversion-focused ad copy (“Ready to move forward? Here’s what happens next.”)
Time-based recency segments: Visitors from the last 7 days are more likely to still be in active consideration than visitors from 60 days ago. Bid higher for recent visitors, lower for older ones.
Cart abandoners (e-commerce): Someone who added a product to cart and didn’t purchase is your highest-value remarketing audience. Use dynamic remarketing to show them the specific product they abandoned. These campaigns typically have conversion rates 2–3x higher than standard Display campaigns.
Converters: Exclude people who already converted from your conversion-focused remarketing campaigns. Someone who hired you last month doesn’t need to see your “Get a Free Quote” ad.
Display Remarketing: The Creative Challenge
Display remarketing ads need to be visually distinct from the noise of the websites they appear on. The creative challenge is: how do you make someone stop scrolling and remember who you are?
Responsive Display Ads: Upload your logo, a headline, a description, and several images. Google assembles them into different formats (banner, square, native) automatically. This is the simplest approach and works well for most small businesses. Use 5–10 image variations to give the algorithm options.
Custom HTML5 ads: Animated ads that can be more visually engaging than static responsive ads. Require design resources. Only worth the investment at $1,500+/month in remarketing spend.
Ad copy for remarketing: Speak to the fact that they already know you. Not “Discover [Company]” (they already found you) — but “Still thinking about [service]? Here’s why 200+ businesses chose us.” Address the objection you know exists: they visited and didn’t convert, which means something stopped them.
RLSA: The Underused Search Remarketing Strategy
Remarketing Lists for Search Ads (RLSA) is the most underused remarketing strategy in small business Google Ads accounts. Here’s the concept: when past website visitors search for your keywords on Google, you bid more aggressively to show up for them.
The logic is sound. A past visitor searching for your service is more qualified than a cold searcher — they’ve already been to your site. Winning that second search moment is worth paying a premium for.
Implementation: In your existing Search campaigns, navigate to Audiences, add your remarketing lists, and set bid adjustments of +20–50% for past visitors. You’re not creating a separate remarketing campaign — you’re layering bid premiums on existing search campaigns.
This strategy works even at small scale. With 100+ visitors in your remarketing list (Google’s minimum), you can start RLSA bid adjustments and capture the high-intent search moments that follow initial site visits.
What to Expect from Remarketing Performance
Compared to cold traffic campaigns, well-run remarketing typically shows:
- Higher CTR: Past visitors recognize your brand and click more readily — 3–5x higher CTR is common
- Better conversion rate: Warmer audience, higher intent — typically 2–4x better than cold Display traffic
- Lower CPC: High Quality Scores from relevance improve ad rank efficiency
Remarketing doesn’t work in isolation. If your original site visit experience is poor (slow load times, confusing navigation, no clear value proposition), remarketing just shows more people the experience that already failed to convert them. Fix the site before spending significantly on remarketing.
Budget Allocation for Remarketing
As a general rule, allocate 15–25% of your total Google Ads budget to remarketing if you have sufficient traffic volume to support audience lists.
For businesses spending $1,000–$2,000/month on Google Ads:
- $150–$400 toward remarketing (Display + RLSA bid adjustments)
- Remainder on primary Search campaigns
If your site traffic is under 500 visits/month, you may not have large enough audience lists to make Display remarketing efficient. Focus on RLSA bid adjustments first (lower threshold, piggybacks on existing Search campaigns) and add Display remarketing as traffic grows.

FAQ
Does Google remarketing show my ads on every site the visitor goes to? Only sites that are part of Google’s Display Network, which includes millions of partner sites but not every website on the internet. YouTube (for video remarketing) and Gmail (for Discovery ads) are also included if you set those placements.
How long can I keep a visitor in my remarketing audience? Up to 540 days in Display campaigns, up to 180 days for RLSA. The practical question is how long your sales cycle is. For a service with a 30-day consideration cycle, keeping someone in your remarketing list for 90 days is probably enough. For high-ticket purchases (luxury goods, enterprise software), longer windows make sense.
What’s the difference between remarketing and dynamic remarketing? Standard remarketing shows a general ad to past visitors. Dynamic remarketing shows an ad featuring the specific product or page a visitor viewed. Dynamic remarketing requires a product feed (for e-commerce) or a custom feed, and it performs significantly better than static remarketing for product businesses.
Is remarketing available in Smart campaigns? Limited remarketing capability exists in Smart campaigns, but you can’t fully segment your audiences or apply RLSA bid adjustments. This is one of the reasons manual campaign management gives you more control — you can use your own remarketing lists precisely. See our guide on Smart vs. manual campaigns for more on this.
My audience list says “0 users.” Why? Most commonly because the remarketing tag isn’t installed correctly, or because the list was created but the tag was placed on only some pages instead of all pages. Check your tag implementation via Google Tag Assistant and confirm it fires on every page. Also, newly created lists take 24–48 hours to populate.
Can I use my Google Ads remarketing audiences in Google Display & Video 360? Yes, if you have access to DV360 (Google’s premium programmatic platform). For most small businesses, this isn’t relevant — DV360 is built for larger advertisers. Standard Google Ads remarketing covers the same channels at a small-business-appropriate management level.
