Ecommerce advertising strategies for 2025

The complete guide to multi-platform ecommerce advertising

Your guide to ecommerce advertising best practices with Klaviyo.

INTRODUCTION

Ecommerce advertising has evolved far beyond simple product promotion. As customer acquisition costs climb and privacy changes reshape targeting capabilities, today’s most successful brands adopt a sophisticated mix of platforms, creative strategies, and zero- and first-party data to acquire and retain customers profitably.

This comprehensive guide breaks down proven strategies across 11 major advertising platforms, from Facebook and Instagram to other names like WhatsApp. With examples from real-life brands, you’ll learn exactly how top performers:

  • Create effective advertising strategies for each major platform.
  • Drive conversions through platform-specific best practices.
  • Maximize performance on emerging advertising channels.

By connecting Klaviyo to these major ad platforms, you can create more targeted campaigns, find valuable lookalike audiences, and track performance across channels.

Facebook Advertising

Facebook Ads: acquisition and retargeting

Facebook remains a cornerstone of ecommerce advertising, offering unmatched audience scale and sophisticated targeting capabilities. The platform excels at both cold traffic acquisition and retargeting campaigns, with particularly strong performance for brands selling products between $30 and $150.

When integrated with your marketing platform, Facebook’s advertising tools can turn zero- and first-party data into highly targeted audience segments.

Image shows a Facebook Ad from toothpaste tablet brand Bite, featuring a 5-star review and testimonial from a customer, Caily B, which reads, “100% recommend to anyone considering solid toothpaste or low waste alternative.” The ad features a photo of a toothbrush propped up on a Bite canister with a tablet perched on the bristles, all against a soothing blue background.

While customer testimonials work across platforms, they’re especially powerful on Facebook, where the algorithm favors content that drives meaningful interactions. The platform’s diverse ad formats—from carousel posts to video testimonials—let you showcase customer success stories in ways that feel native to users’ feeds.

Structure your testimonial ads to highlight specific product benefits that address common objections. For example, when running ads for a skincare product, you might:

  • Lead with before/after customer photos.
  • Include 2–3 specific quotes about results (“My dark spots faded in 3 weeks”).
  • Add social proof elements like star ratings.
  • Close with a clear product shot and price point.

Bite, a brand that sells zero-waste toothpaste tablets, offers a great example of this. Their Facebook testimonial ad rotates through a series of customer reviews, with prominent 5-star visuals in both the testimonials and headlines, reinforcing the social proof.

This visual consistency helps build trust while maintaining viewer attention—exactly the type of authentic engagement that Facebook’s algorithm rewards.

Instagram Advertising

Instagram Ads: product discovery and impulse buys

Instagram’s advertising ecosystem differs somewhat from Facebook’s, despite their shared back end. The platform’s visual-first approach and dedicated shopping features make it ideal for product discovery and impulse purchases.

In this Instagram ad, dog dental powder company PetLab Co. combines the power of expert advice and user-generated content (UGC). The ad establishes credibility by featuring a veterinarian recommending the teeth cleaning product, then cuts to clips of real dogs and pet owner testimonials. The ad concludes by encouraging viewers to “Click below to shop now” to create urgency and make it easy for them to buy the product.

Here are a few ways to replicate this strategy:

  • Shoot product photos in real-world contexts.
  • Use Instagram’s product tagging in both organic and paid content.
  • Match your ad aesthetic to your organic feed.
  • Test both static and video formats with shopping overlays.

TikTok Advertising

TikTok: authenticity and viral potential

On TikTok, the algorithm prioritizes content over followers, making every post a potential viral hit. With 120.5 million monthly active users in the US alone, mostly 18–34 years old, the platform’s rapid-fire format demands thumb-stopping content that captures attention in under 3 seconds.

For TikTok ads to perform, they need to blend seamlessly with organic content while driving clear actions. Your TikTok ecommerce strategy needs certain key elements to succeed:

  • Native content: Film vertically in 9:16 format with trending sounds.
  • Quick hooks: Capture attention in the first few seconds.
  • Authenticity: Raw, unpolished content often outperforms high production value.

For example, a skincare brand might show a split-screen “Get Ready With Me” ad where a real customer applies the product on one side while highlighting results on the other.

Google Advertising

Google Ads: high-intent traffic

Google Ads offers two distinct approaches to ecommerce advertising: Search and Shopping.

While Search Ads appear in text format based on keyword matches, Shopping Ads display product images, prices, and details directly in search results. Both formats tap into high-intent traffic—people actively searching for products like yours.

Your Search Ad strategy needs to align with where customers are in their buying journey. For each product category, think about employing different strategies for each phase:

  • Research phase: Target broad informational keywords.
  • Comparison phase: Focus on specific product features and benefits.
  • Purchase phase: Bid on exact product names and buying terms.

For example, if you sell running shoes, your keywords might progress from “best shoes for marathon training” (research) to “Nike Air Zoom vs. Brooks Ghost” (comparison) to “Nike Air Zoom Pegasus 39 price” (purchase).

Tip: Match each ad’s landing page and copy to the searcher’s intent at that stage.

Amazon Advertising

Amazon: competitive product promotion

Amazon functions as both a marketplace and an advertising platform, offering Sponsored Products, Sponsored Brands, and Sponsored Display ads. While other platforms focus on discovery, Amazon captures customers with high purchase intent.

Though it’s not an owned channel, Amazon’s massive reach can significantly expand your brand’s exposure to new customers. The platform’s advertising tools let you promote products directly within search results and product detail pages, while brand registry unlocks additional promotional features.

Success on Amazon requires visibility in a sea of similar products. Here are a few ways to improve your position:

  • Target competitor Amazon Standard Identification Numbers (ASINs) with Sponsored Product ads.
  • Use negative keywords to avoid wasting ad spend.
  • Adjust bids based on placement performance.
  • Test different match types for each keyword.
  • Monitor your advertising cost of sale (ACoS).

In this Amazon search result for “tinned seafood”, seafood brand Fishwife’s products appear in a sponsored “Customers frequently viewed” section of Amazon.

Image shows an Amazon search result for “tinned seafood,” with several products lined up horizontally. The first result, outlined with a red box, is tagged “Best Seller” in the upper left corner and shows 7 tins of Fishwife seafood. The product is called “Fishwife Starter 7-Pack (Variety of Tinned Seafood including Smoked Salmon)” for $72.00.

Pinterest Advertising

Pinterest: from discovery to decision to purchase

Unlike platforms focused on immediate engagement, Pinterest serves as a visual discovery engine where users plan future purchases. In fact, 85% of weekly active Pinterest users have made a purchase from their Pins.

“As a leading full-funnel solution that drives people from discovery to decision to purchase, all in one place, Pinterest continues to drive impact for brands—especially those offering luxury products,” writes Anthony DelPizzo, former product marketing lead at Klaviyo.

With its robust visual search technology, Pinterest demands a different advertising approach. The platform combines search engine capabilities with social media features. A few key elements make it unique:

WhatsApp Advertising

WhatsApp: two-way communication

WhatsApp Business transforms direct messaging into a powerful sales channel through features like product catalogs, automated responses, and broadcast lists. Beyond traditional advertising, WhatsApp enables immediate two-way communication with customers.

The platform’s end-to-end encryption and verification badges build trust, while its API integration capabilities streamline customer service.

A cosmetics brand can turn WhatsApp into a digital storefront by designing interactive product discovery flows. Here’s an example of a message flow that could work for this:

  • Customer: “I’m looking for a new moisturizer.”
  • Auto-response: “Thanks for reaching out! Would you say your skin is: 1) Dry 2) Oily 3) Combination”
  • [Customer selects option]
  • Auto-response: [Sends catalog of relevant products with descriptions and prices]

In WhatsApp, your brand can take a similar approach, setting up quick replies for common questions and using message templates to guide customers through their buying journey.

Tip: Your product catalog should include clear images, prices, and descriptions—all accessible within the chat interface.

Bonus platforms

Snapchat, LinkedIn, X, and Reddit

Snapchat’s AR capabilities create unique opportunities for product visualization. For ecommerce brands, this could translate into virtual try-ons and immersive product demonstrations.

Here are a few ideas for turning your products into interactive AR experiences on Snapchat:

  • Beauty brands can create makeup try-on lenses.
  • Furniture retailers can help users visualize items in their space.
  • Fashion brands can offer virtual fitting rooms.
  • Accessory brands can let users test different styles.

Key takeaways

Success in ecommerce advertising demands a strategic balance across multiple platforms. To maximize your advertising impact:

  • Choose platforms strategically: Select channels based on where your high-value customers spend time, not where advertising costs least.
  • Use data intelligently: Connect your zero- and first-party customer data to ad platforms for more precise targeting and better returns.
  • Adapt to each platform: Create native content that respects each platform’s unique characteristics while maintaining your brand voice.

The future of ecommerce advertising lies in seamlessly connecting these platforms while staying agile enough to embrace new channels as they emerge.

By combining Klaviyo’s data and owned channel capabilities with third-party advertising platforms, you get the best of both worlds.
