Summer sales 2026: Google and Meta campaigns

Summer sales are ecommerce’s quiet Black Friday. They don’t carry the same noise, but they pack weeks of high buying intent into a window when a lot of brands take their foot off the gas because “it’s summer”. What I see every year is the same: accounts that reach July without touching anything since June, running the same budget, the same creatives, and the same ad copy from three months ago.

That leaves money on the table. Someone searching “running shoes sale” or “summer deals” in July has a different intent than in March, and the account has to reflect it. This guide covers what to do in Google and Meta before and during the 2026 summer sales, how to split the budget between them, and the mistakes that show up every season.

In 30 seconds:

• In Spain, summer sales have had no fixed dates since the 2012 liberalization; in practice the bulk kicks off in early July, so the prep happens in June
• In Google, the job is capturing demand: a clean feed, bids that ride the peak, and remarketing to people who already visited
• In Meta, the job is generating demand: fresh creatives carrying the sale message and an updated catalog
• The budget split isn’t 50/50: it depends on whether your bottleneck is capturing existing demand or creating it
• The most expensive mistake is not separating sale performance from the rest, and not being able to measure what worked

When do the 2026 summer sales start, and why do the dates matter?

The bulk of summer sales kicks off in early July and stretches into August, though each store sets its own dates.

In Spain, since sales periods were deregulated, there’s no official calendar: each retailer decides when and how deep to discount. In practice that means the search peak for “sales” and “summer deals” concentrates in the first half of July, with a spike when the big chains announce their discounts and drag the rest of the market along.

For the ad account, the consequence is clear: the prep happens in June, not July. Raising budgets on the same day the sales start means arriving late, because automated bidding campaigns need days to readjust to the new demand. What works best in my experience is preparing the campaigns by mid-June and letting the system learn on the prior weeks’ traffic, so that when the peak hits it isn’t starting from scratch.

What should you do in Google Ads before the sales?

In Google the job is capture: the demand already exists and people are searching for it, so the goal is to miss no relevant search and ride the peak without your bids falling short.

What I always check before a sales season:

• The Shopping and Performance Max feed. Prices updated with the discount applied, the sale price (sale_price) attribute set in Merchant Center, availability correct. A feed with stale prices during the sales is the most expensive failure and the most invisible.
• Budget and bidding strategy. If you use an automated ROAS-target bid, lowering the target slightly during the peak lets more volume in; raising it strangles the campaign exactly when demand is highest. The logic of automated bidding with Smart Bidding shifts depending on the target you set.
• Remarketing. Someone who viewed the product page in June and didn’t buy is the most profitable audience during sales, because now the product is cheaper. Having Google Ads remarketing lists active and segmented before the peak is one of the highest-return moves.
• Brand + “sale” searches. People search “[your brand] sale” or “[your brand] discount”. If you don’t cover those terms, an affiliate or a competitor takes them.

If you’re torn between concentrating spend on standard Shopping or on Performance Max for the season, I work through it in Google Shopping vs Performance Max, because the answer depends on how much control you want over where your products show.

How should you structure Meta campaigns for the sales?

In Meta the job is the opposite: the demand isn’t searching for you, you have to spark it. The sale message has to interrupt the scroll, and that depends on the creative far more than on the targeting.

Three things make the difference:

Fresh creatives, not the usual ones with a “sale” sticker. The algorithm and the user both spot recycled content. A short video showing the product with the discounted price visible performs better than a static image with a discount banner slapped on top.

An updated catalog. If you sell with Advantage+ Shopping or catalog campaigns, prices and stock have to be synced just like in Google. A dynamic ad showing a price that no longer exists burns budget and trust.

Remarketing with real urgency. For people who visited the site or added to cart, the “sale ends Sunday” message works, but only if it’s true. Fake urgency shows, and it wears the brand down. To read that return properly it helps to understand attribution models in Meta, because last-click undervalues the role of these campaigns.

How do you split the budget between Google and Meta?

There’s no universal split. It depends on where your bottleneck is: if you’re short on capturing demand that already exists, Google weighs more; if you’re short on creating demand and getting the offer known, Meta weighs more.

This table sums up each platform’s role in sales season:

In practice, a brand with strong branded search tends to tilt the budget toward Google during the peak, because the demand is already there and just needs collecting. A younger brand, or one with impulse products, leans more on Meta so the offer reaches people who aren’t searching yet. What almost never works is splitting blindly and not moving anything during the season: both platforms need daily watching while the peak lasts.

What mistakes repeat every season?

Every summer I see the same three failures, and all three are avoidable.

The first: stale prices in the feeds. The discount gets applied on the site, but nobody checks that the Shopping feed and the Meta catalog reflect it. The result: ads promising a price that no longer holds, or not showing the discount and competing at a disadvantage.

The second: raising budget without prepping the bids. Pouring more money into a campaign the day the sales start, without having adjusted the ROAS target or left room to learn, usually performs worse than touching nothing. The system reacts late and the peak gets wasted.

The third: not separating sale activity from the rest. If the season runs inside the same old campaigns, with no label or segment isolating it, you can’t tell what worked once it’s over. And what you can’t measure, you can’t repeat next year.

How do you know if the sales worked?

By looking at the season’s performance isolated from the rest, not the overall sales figure.

The classic measurement mistake is celebrating that July sold more than June. Of course it sold more: there are sales on. The useful question is different: did the money spent on advertising during the sales return better or worse than your average? Answering that needs the seasonal campaigns labeled from the start, so you can compare their ROAS against your baseline.

And there’s an attribution nuance that changes the conclusions. During peaks, Meta often influences purchases that Google takes on the last click, because people see the ad on Instagram and then search the brand on Google. If you judge Meta on last click alone, you undervalue it. Reviewing how to improve Meta Ads ROAS helps read that return with more context before cutting budget hastily.

Frequently asked questions

When should you start preparing the summer sales campaigns?

Mid-June. Automated bidding campaigns need days of learning on real traffic before the peak, so reaching July with everything freshly built means arriving late. Feed, creative and budget prep happens in June so the system is run-in when demand kicks off.

Should you spend more on Google or Meta during the sales?

It depends on the bottleneck. If your brand already gets searches, Google captures that demand with better return and the budget should tilt there. If you need more people to learn about the offer, Meta generates that reach. Most accounts don’t run on a fixed 50/50, but adjust based on what’s missing.

Should you lower the ROAS target during the sales?

Generally, lowering it a little lets more volume in at peak demand, which is exactly what you want in a sale. Raising it strangles the campaign when there are most opportunities. The exact adjustment depends on your margin with the discount applied: if the discounted product leaves little margin, the target can’t be that aggressive.

Do the usual Meta creatives work with a sale banner on top?

They work worse than fresh creatives. Both the user and the system detect recycled content, and performance shows it. For sales it’s worth producing specific pieces that show the product with the discounted price natively, not as a patch over an old ad.

How do I stop the feed showing prices without the discount?

By manually checking a sample of products in Merchant Center and in the Meta catalog the day you switch the sales on, rather than trusting the sync to work on its own. Price mismatches between the site and the feed are the most common and most invisible failure of the season.

Conclusion: the season is won in June

Summer sales reward whoever shows up prepared, not whoever reacts. The real work is in June: clean feeds, adjusted bids, active remarketing, fresh creatives, and a measurement setup that isolates the season. Whoever does that rides the peak; whoever improvises in July chases it from behind.

The mistake that repeats most isn’t strategic, it’s execution: stale prices, budgets raised without prep, and unlabeled campaigns that can’t be measured afterward. None of the three is hard to avoid; you just have to do it before the rush starts.
