Google Ads for Black Friday: The Ultimate ROI Guide

October is undoubtedly the month in which the foundation for the success or failure of Black Friday is built. The problem is that most of your competitors believe that the Google Ads strategy for Black Friday consists simply of increasing the budget in the week of the event. And they couldn't be more wrong.

On the most competitive day of the year for global retail, Cost Per Click (CPC) skyrockets and the fight for attention is fierce. Playing the same game as everyone else will only drain your budget and deliver a mediocre ROI. Success, on the other hand, requires a surgical strategy, divided into phases and focused on intelligence, not just money.

That's why we've prepared this definitive guide . In it, we'll detail 5 proven campaign strategies that we at e-Plus use to maximize our clients' return on investment. By the end of this reading, you'll have a clear battle plan to transform Google Ads into your biggest sales machine this Black Friday.

THE FATAL ERROR: THINKING THAT BLACK FRIDAY STARTS IN NOVEMBER

The first lesson from Google Ads for Black Friday is: the event doesn't start on Friday. It starts now. That's because consumers begin their research journey weeks in advance, comparing models, reading reviews , and creating their "wish lists."

If you only show up for it the week of the event, you'll encounter two barriers:

1. The CPC will be at its peak, making each click very expensive.
2. You will be just one more in the crowd, without having built no previous relationship with that consumer.

The winning strategy is divided into three phases:

• Phase 1 – Warm-up (October to ~November 15): Focus on capturing intent and building audience lists.
• Phase 2 – Event (Black Friday Week): Focus on maximum conversion, using the audiences you've built.
• Phase 3 – Post-Event (Cyber ​​Monday and December): Focus in remarketing e loyalty.

Next, we'll focus our 5 strategies on how to master these phases.

The goal here is to build huge, qualified remarketing lists before the CPC skyrockets. In other words, at this stage, your main objective isn't (necessarily) to sell. It's actually to identify who is in "search mode."

How to run:

• Discovery and YouTube campaigns: Create Discovery and YouTube campaigns (with CPV – Cost per View) that are much cheaper than Search campaigns.
• Valuable content: Don't advertise your "store." Advertise valuable content.

For example: a store in the electronics segment creates a short video for YouTube: “ The 5 best 4K TVs to keep an eye on this Black Friday ”. Then, they boost this video to audiences with an “ Interest in Electronics ” interest.

The result is that they spend pennies per view to reach thousands of people who are actively considering buying a TV. But most importantly? They create two remarketing lists in Google Ads:

1. “They saw the video of the 5 TVs.”
2. “Visited the blog post 'TV Guide 2025'”.

In short, these lists are your "oil well" for Phase 2. You're building a warm, high-intent audience, paying much less.

STRATEGY 2: THE MACHINE (MAX SEASONAL PERFORMANCE)

Performance Max (PMax) is Google's most powerful campaign for e-commerce. On Black Friday , it's indispensable. However, simply "turning on" PMax isn't a strategy. You need to pilot the tool.

How to run:

1- Resource groups (asset groups) specific

First, don't use your usual creatives. Create new and unique Resource Groups for Black Friday.

Eg

• Titles: "Real Black Friday Deals","Up to 60% OFF TODAY ONLY","Black Friday Price Guarantee".
• Images: Use banners with discount seals, countdowns, and the event's visual identity.
• Videos: create short videos (15s) focused on the urgency of the offers.

2- Public signs (audience signals)

Secondly, here's the secret. "Feed" your PMax the right audiences to accelerate AI learning.

• Audience 1: your customer lists (see Strategy 3).
• Audience 2: as remarketing lists that you created in Phase 1 (“Did you see the video of the 5 TVs?").
• Audience 3: custom audiences of those who searched for competitor terms or specific products.

3- The secret tool: seasonality adjustments

Finally, this is a specialist tactic. While Google's Smart Bidding already manages seasonal events, Black Friday is a very short (1-7 days) and abrupt peak. Google's own documentation recommends using Seasonality Adjustments only for these significant and anticipated changes.

• Action: in your account of Google Ads, click on the icon Tools and Settings . From the drop-down menu, go to Budgets and bids and click Settings. At the top, select the tab Seasonal.
• How to set up: create a new adjustment. Set the exact period (e.g., November 28-30). In “Fit type“, Select“Conversion rate". In "Scope“, choose the campaigns that will receive the impact (Google confirms that it works for PMax, Research e Standard Shopping Mall).
• The cat jump: in "Conversion rate adjustment", enter the increase you expect. If you expect your conversions to triple in those days, enter +200%.
• As a result, Google's algorithm will act much more aggressively on the exact days you specified, understanding that incoming traffic has more value and optimizing bids to capture this explosive demand.

STRATEGY 3: GOLD (CUSTOMER MATCH / CUSTOMER LIST)

It's simple math: acquiring a new customer is 5 to 25 times more expensive than retaining an existing one . This logic is even more true during Black Friday . Therefore, your biggest ROI lies in your existing customer base.

How to run:

1- Segment your Lists

Upload your customer lists to Google Ads , but not all at once. Segment them:

• List 1: Last Black Friday shoppers (very high repurchase intention).
• List 2: VIP customers (highest average ticket).
• List 3: All buyers from the last 365 days.

2- Use lists aggressively:

• At PMax: add them as Public Signs (as we saw in Strategy 2).
• In Search/Shopping Campaigns: Apply a +100% or +200% bid modifier to these listings. This ensures that when your existing customer searches for a product you sell, your ad is the first one they see.

STRATEGY 4: THE BATTLE OF THE SHELF (GOOGLE SHOPPING OPTIMIZATION)

In Google Ads for Black Friday , Google Shopping is your main visual battleground. Remember: having the lowest price is useless if your ad doesn't stand out.

How to run:

1- Feed Title Optimization

Ensure that your product titles in the data feed follow a clear and optimized structure: Brand + Product + Main Attribute (e.g., Color/Size/Model ).

• Bad: "Running shoes"
• Good: "Nike Pegasus Running Shoes Men's Size 41 Black"

2- The Secret Weapon: Merchant Center Promotions

You know that " SPECIAL OFFER " or " 20% OFF " label that appears on some Shopping ads and makes the CTR (click-through rate) skyrocket? That's not automatic.

• Action: you need to configure this manually within your Google Merchant Center, in the Marketing > Promotions tab.
• But be careful, These promotions require prior approval from Google, which can take days. So if you leave it to the week of the Black Friday, it will be too late. Do it now, in October.

STRATEGY 5: THE SHIELD (DEFENSIVE BRAND CAMPAIGNS)

Rest assured: your competitors will be bidding on your store's name. If a customer types "CasaTech Store" and the first link is from your competitor, you're losing your easiest and cheapest sale.

How to run:

1. Create a branded search campaign: create a campaign Search Network dedicated, which will be activated only when someone types your brand name (e.g.: “CasaTech”, “Loja CasaTech”, “casatech.com.br”).
2. Sufficient budget: monitor the “Percentage of Impressions" of this campaign. It should be as close to 100% as possible. This means you are "armored."
3. Use Black Friday sitelinks: optimize the sitelinks (the extra links below the main ad) for the event:
   • "Black Friday deals"
   • "Low Price Guarantee"
   • "Contact Us – BF"
   • "New Releases"

Without a doubt, this campaign will have the highest ROI and the lowest CPC of your entire account, protecting your most valuable asset: your loyal customer.

CONCLUSION: STRATEGY WINS

In short, success on Google Ads for Black Friday isn't about who has the biggest budget. It's about who has the smartest plan.

As we have seen, the winning strategy is a symphony of coordinated actions:

1. Start early, building qualified audiences.
2. Master PMax with seasonal creatives and Seasonality Adjustments.
3. Prioritize your old customers to Customer Match.
4. Stand out in the mall with perfect titles and promotional seals.
5. Defend your territory with brand campaigns.

Executing all of this amidst the day-to-day operations of e-commerce is undoubtedly a complex challenge. But it's what separates amateurs from professionals and profits from losses.

FAQs About Google Ads for Black Friday

When should I start my Black Friday campaigns?

You should start immediately, meaning now (October). This is the "Warm-Up Phase," where you use cheaper campaigns (YouTube, Discovery) to build qualified remarketing lists, which will then be your primary target during the week of the event, when the price per click (CPC) is high.

Does the CPC get much more expensive on Black Friday?

Yes, dramatically. Competition for high-intent keywords increases exponentially. This is precisely why strategies like Customer Match (customer lists) and remarketing are vital, as they target an audience that already knows you, resulting in a much lower cost of acquisition (CAC).

Max Performance or Standard Shopping for Black Friday?

Without a doubt, Performance Max (PMax) is Google's official recommendation and the most powerful. This is because it accesses all of Google's inventory (Search, Shopping, YouTube, etc.) in a single campaign. However, the key is to feed it the right Audience Signals (your customer lists and remarketing) and use Black Friday-specific Resource Groups.

What is “Seasonality Adjustment” in Google Ads?

It's an advanced tool for smart bidding. You tell Google about a short period (like the three days of Black Friday) when you expect a drastic increase in conversion rates. This causes the bidding algorithm (Smart Bidding) to adjust more quickly to the spike, becoming more aggressive in capturing those sales.

How do I get the “OFFER” badge to appear on my Google Shopping ad?

This badge is set up within Google Merchant Center, under the "Marketing > Promotions" tab. You need to register the rules for your promotion (e.g., 20% off in 'x' category) and wait for Google's approval. Do this at least two weeks in advance, as approval isn't immediate.
