11 of the the best digital advertising platforms for B2C brands in 2026

Have you seen an ad recently where you thought, “How did they know I’ve been looking for this?”

Digital ads have gotten smarter and more personalized, thanks to better integrations with marketing systems and more advanced targeting options on digital advertising platforms.

Consumers today even like ads they see while they’re scrolling through TikTok or Instagram, precisely because they’re relevant. When you approach them right, ads help people find products they’ve been looking for or solve a problem they’ve been stuck on. Kantar’s Media Reactions 2025 report found that more than half of consumers (57%) have positive feelings about ads.

For B2C brands, digital ads are part of a personalized omnichannel marketing strategy that reaches customers across all the channels where they engage, with meaningful content, when they’re most active. WPP Media reports that advertising spend reached an estimated $1.14 trillion in 2025, and they predict that global advertising revenue will grow 7% in 2026.

With growing approval from consumers and massive investments from brands, B2C marketers need to make sure they’re using the best digital advertising platforms to get the best possible return on ad spend (ROAS).

What are digital advertising platforms?

Digital advertising platforms allow you to target specific audiences with sponsored ads in formats like images, videos, carousels, and stories. Many platforms have bid-based payment structures using cost per impression, cost per engagement, or cost per conversion.

By connecting your B2C CRM with your digital advertising platform, you can target your existing audience with ads, find new audiences that match the characteristics of your customers, and use customer data to personalize ads.

How do digital advertising platforms help marketers reach their goals?

When using a digital advertising platform, your goals should align with your bidding strategy.

Here are some of the most common goals marketers have for digital ads, and the recommended bidding strategy for each:

• Increasing brand awareness: Optimize for impressions and reach.
• Bringing in new subscribers: Optimize for sign-ups.
• Driving engagement: Optimize for messages, video views, likes, comments or saves.
• Generating sales: Optimize for conversions on your website.

After launching your ads, it’s best practice to continuously update your creative, targeting parameters, and audiences. This helps reduce your costs and improve performance, driving up your ROAS.

11 of the best digital advertising platforms for engaging a B2C audience

As a B2C brand, you want to show up where your audience is active to make the most of your advertising budget. Here are 11 digital advertising platforms that can help you efficiently reach new and existing customers:

TikTok for Business

According to a Kepios data analysis, brands can reach almost 2 billion people on TikTok. TikTok ads help brands build their TikTok community, find new customers, and convert visitors into buyers. These ads are specifically relevant for CPG and retail brands, and good for brands at any budget since you can only pay for the actions that you want.

TikTok commissioned research with Nielsen to understand the impact of TikTok ads and found a 96% higher paid media ROAS than other digital media channels, and 2.9x higher sales efficiency. At the time, TikTok was also the fastest-growing channel for discovering new brands.

If you already have established lists and segments in Klaviyo B2C CRM, you can sync these audiences into TikTok for Business using Klaviyo’s TikTok Audiences integration to target them with ads, or find lookalike audiences that reflect your top customers.

And in the other direction, once you generate new subscribers via TikTok ads, you can use Klaviyo’s TikTok Lead Ads integration to automatically sync them into the CRM in real time, where you can continue the conversation via email, text messages, WhatsApp messages, and more.

Google Ads

You can choose between a few different types of Google Ads campaigns, including Performance Max Campaigns, search ads, display ads, shopping ads, video ads, and app ads across the Google ecosystem—Google Search, Google Suite, and YouTube. If you haven’t run ads using Google Ads before, they offer new advertisers ad credits to get started and see how they work out.

WordStream analyzed 17,000+ search ad campaigns and found that cost per click averages $4.66, while conversion rate averages 6.96%. Overall, ecommerce and retail brands tend to have lower costs per click, and services businesses have higher costs per click.

To bring Google Ads into your greater marketing strategy and help reduce the costs of your ads, you can use Klaviyo’s Google Ads integration to:

• Sync Klaviyo segments to Google Ads and target existing customers.
• Create integrated campaigns using Klaviyo data in Google Ads.
• Measure and improve ad performance using Klaviyo insights, like purchases, marketing engagement, or customer lifetime value.

Brand group Helen of Troy uses Klaviyo’s Google Ads integration to build lookalike audiences to target, and they exclude current email and text message marketing subscribers from paid acquisition campaigns to focus on new customers. In an increasingly cookieless environment, the integration gives Helen of Troy more access to customer data for better paid media targeting.

Meta for Business

With Meta for Business, you can target audiences across Facebook ads, Instagram ads, and ads clicking to WhatsApp and Messenger—and these ads have the potential to reach billions of people. The Kepios data analysis shows an estimated audience of 2.35 billion on Facebook, 1.91 billion on Instagram, and 942 million on Messenger.

For reference, WordStream finds that for Facebook ads:

• The average click rate for traffic campaigns is 1.71%.
• The average cost per click for traffic campaigns is $0.70.
• The average click rate for leads campaigns is 2.59%.
• The average cost per click for leads campaigns is $1.92.
• The average conversion rate for leads campaigns is 7.72%.
• The average cost per lead is $27.66.

Meta ads are ideal for increasing sales, driving in-store traffic, and bringing in new customers more efficiently. With Klaviyo’s Meta Ads integration, you can:

• Reach audiences like recent browsers, unengaged customers, or cart abandoners with retargeting ads.
• Save money by avoiding overlap, and focus on customers who are predicted to be high-value or who have shopped with you in the past.
• Cross-sell to recent buyers with products you know they’ll love.
• Create lookalike audiences from lists of your best customers.

Men’s underwear brand 2(X)IST uses Klaviyo’s Meta Ads integration for smarter remarketing ad campaigns. Since their most loyal customers don’t need paid reminders to keep purchasing, they exclude loyalists and champions from paid campaigns using RFM segments. After restructuring their paid campaigns, their ROAS increased 61% YoY.

Pinterest Ads Manager

Pinterest has a growing audience of about 350 million, according to the Kepios data analysis. Pinterest ads are sponsored posts that show up in users’ Pinterest feeds. They can be geared towards awareness, consideration, or conversion, helping you reach customers across their entire journey.

According to Pinterest, the No. 1 reason users are on the platform is to discover products and brands. That makes Pinterest a strong social media platform if you’re looking to bring in new customers or promote new products to existing audiences.

As part of your Pinterest marketing strategy, ads are an efficient way to get in front of only the folks that are most likely to take action, rather than trying to get in front of everyone possible.

Using Klaviyo’s Pinterest Audiences integration, you can bring Klaviyo audiences into Pinterest to target customers and subscribers, and build:

• Lookalike audiences that reflect the behaviors of your best customers
• Exclusionary audiences that suppress recently converted audiences from ads
• Engagement audiences of contacts who recently engaged but didn’t convert

AdRoll

AdRoll is an AI-powered connected advertising platform that helps businesses run multi-channel advertising campaigns across the whole marketing lifecycle.

To improve omnichannel marketing, Klaviyo’s AdRoll integration lets you import Klaviyo lists and segments into the platform, then retarget audiences across the web, connected TV (CTV), and social sites like Meta, TikTok, and Pinterest.

By connecting Klaviyo with AdRoll, you can also access performance metrics like ROAS and click rates, so you can optimize campaigns and get more out of your ad budget.

Vibe

Vibe is an AI-powered platform for retargeting audiences with TV ads, called CTV campaigns. Vibe is geared towards ecommerce, retail, gaming, and entertainment brands, and others that want to generate awareness, drive sales, attract traffic, and retarget subscribers.

Today, CTV ads are accessible to companies of any size, unlike in the past when only large brands advertised on TV. Vibe offers a simple way to create TV ads—you can enter your URL and create branded ad spots using AI in 30 seconds.

To reach existing audiences across streaming apps and TV channels, use Klaviyo’s Vibe integration to target key segments, retarget website visitors, and re-engage email subscribers with CTV ads.

• Send DMs about product drops or offers to your whole audience.

Let’s say your average order value is $25 and you have 100,000 social media followers. Pinpoint estimates that by using their advertising platform, you could generate an additional $25,000 per month.

Blend helps you get more from your ad dollars by analyzing performance across channels and taking action on its own, improving budget and creative to improve results. You can build one ad creative, then send it out across Facebook, Instagram, Google, TikTok, and YouTube in seconds.

Using Klaviyo’s Blend AI integration, you can bring in customer insights from your CRM to:

• Capture cart data.

Customers.ai

Customers.ai is a pixel on your ecommerce website that helps identify high-value customers and visitors for flows, like people who have abandoned carts, viewed products, or visited high-intent pages.

Customers.ai uses AI models to analyze on-site activities and find patterns, giving you more data about browsing behavior, product interest, and intent, which improves the performance of your flows. It gives you the ability to:

• Capture more customer behavior than you can get with traditional tracking.
• Build audiences by level of purchase intent.
• Connect your messages to your audience to improve visibility and engagement.

Using Klaviyo’s Customers.ai integration, you can identify high-intent visitors and send the event data to Klaviyo, then understand the revenue you’re driving from these smarter flows.

One health and wellness ecommerce brand used Customers.ai with Klaviyo to learn who visits their site, segment visitors based on which ads they clicked to get there and which product pages they visited, and finally send more relevant abandoned cart automations.
