Ecommerce Advertising: Strategies to Drive Online Sales

It helps us show our products and services to people where they spend a lot of time- online. This guide explains the basics of ecommerce ads, including the benefits, limits, strategies, and methods we can use. Keep reading to learn how we can grow our ecommerce sales successfully.

What is Ecommerce Advertising?

Ecommerce advertising means promoting our products, services, or online store using paid spots on websites, apps, or other digital spaces that we don’t own. The main goal is to bring users to a landing page where they can buy a product or sign up for a service.

For example, think about an Instagram ad for a phone service:

• The ad shows up in the middle of regular Instagram posts.
• When someone taps on the ad, they go to a page on the company’s website.
• There, a big button says “Get Started,” making it easy to sign up.

We can also call ecommerce ads by other names like paid ads, online ads, digital ads, or ecomm ads.

Ecommerce Advertising vs. Ecommerce Marketing

Ecommerce advertising is just one part of ecommerce marketing.

A good marketing plan may include:

• Ecommerce advertising – what we’re talking about in this guide
• Content marketing – like writing blog posts or guides
• Search engine marketing (SEM) – showing up in Google results
• Social media marketing – sharing posts on Facebook, Instagram, etc.
• Influencer content – paying creators to talk about our products
• Affiliate networks – where others promote our store for a commission
• Email campaigns – sending offers and updates to our customers

Some businesses also use older methods like print ads, TV, events, or direct mail. The tactics we choose should match the goals we want to reach.

What Types of Ecommerce Advertising are There?

There are many types of ecommerce ads, depending on the platform and campaign.

Here are a few common ones:

• Display ads – seen on websites using networks like Google Ads
• Search ads – appear in search results on Google or Bing
• Social media ads – show up in feeds on apps like Facebook or LinkedIn
• Marketplace ads – appear on online stores like Amazon or eBay
• Video ads – run before or between videos on YouTube or TikTok
• Forum ads – pop up on websites like Reddit or Quora

We’ll share more about what each platform offers later in the guide.

Why Ecommerce Advertising Matters

Ecommerce ads are a smart way to reach people who are already spending time online.

By 2028, global online sales are expected to reach $6.8 trillion, a big jump from $4.4 trillion.

But the internet is getting more crowded. Organic content (posts we don’t pay to promote) is harder to get noticed because of changing algorithms. Old ways like word of mouth, events, or print ads don’t work as well anymore.

That’s where ecommerce ads help. They bring attention to our products and services—and if they’re good, people will click and buy.

Ecommerce Ads help Reduce High Customer Costs

It’s expensive to gain new customers. We use a number called CAC (Customer Acquisition Cost) to track this. To find it, we divide our total sales and marketing costs by the number of new customers we get.

Ecommerce ads cost less than TV, radio, or newspaper ads. This means we can reach more people online without spending too much.

We can also use pay-per-click (PPC) ads to show our products to the right people at the right time. That’s something traditional ads can’t do.

Ecommerce ads solve the problem of low social reach

In the past, having a strong social media page was enough to turn followers into buyers. Now, it’s much harder without ads. We have to use display ads, boosted posts, or even paid influencer posts to reach new people.

That’s because algorithms now control who sees what. Even if we make a great post, it may not be seen by enough people. Also, funny, shocking, or bold posts often get more attention—but that doesn’t always work for brands.

Luckily, ecommerce ads help us reach the right audience by:

• Targeting people who like topics related to our brand
• Retargeting those who’ve already visited our site
• Partnering with influencers who actually enjoy our products

Algorithms will keep changing.

But if we adjust our strategy, ecommerce ads can help us stay in front of the right customers.

Finding PPC Opportunities with AI

If we haven’t yet used AI to improve our paid ad campaigns, we might be missing some big chances. AI has changed the world of marketing in the last few years. It has both good and bad sides, but today, it’s hard to avoid using AI in some way.

Some smart ways we can use AI in ecommerce ads are:

• Making better choices in who to target, how much to spend, and when to show ads
• Restructuring how our paid search accounts are set up
• Checking how well our paid search ads are working

Many major ad platforms already use AI. These include Google’s Performance Max, Amazon Ads, and Meta’s Advantage+ (which needs a Meta account). In short, AI helps us improve our ecommerce campaigns in ways we couldn’t before.

Better Tracking and Visibility Across Channels

Using paid ads as part of our tracking plan is important. It helps us understand where customers come from and gives them a smooth experience.

Today, most people don’t just see an ad and buy right away. They look around, do research, and take time before they decide.

Let’s say someone named Marie wants to buy a product we sell:

• She sees a social media post and thinks it looks good, but doesn’t buy yet.
• The next day, she searches on Google, finds our website, and reads more. She signs up for emails but still doesn’t buy.
• A few days later, she gets an email, wants to buy, but gets distracted.
• Later that night, she sees a retargeted ad on another site, remembers the product, clicks the ad, and finally makes the purchase.

Even though Marie might have bought the product anyway, the retargeted ad helped her finish the process sooner.

That’s why it’s a good idea to include digital ads in our marketing mix. It helps shorten the time between when someone first sees our product and when they decide to buy.

Top Ecommerce Advertising Platforms

The best ecommerce ad platforms give us:

• Control over how we run our ads
• Many ways to reach the right people
• Tools to test and adjust ads as needed
• Smart tracking and reports powered by AI

These platforms help us grow our business, reach more people, and earn more.

The top platforms by ad revenue are:

• Google: $190.5 billion
• Meta (Facebook & Instagram): $146.3 billion
• Amazon: $52.7 billion

Big platforms work for many businesses. But sometimes, smaller platforms help us reach special audiences too.

Let’s look at some top ecommerce platforms and what they offer.

• Google Ads:

Google Ads is the most popular platform for ecommerce advertising. No matter how big or small our business is, we’ll likely want to try Google Ads at some point.

Before diving into details, we should understand the difference between Google Ads and AdSense.

• Google Ads vs. AdSense

These are two different tools made by Google for different users.

Google Ads is for advertisers (like us) who want to show ads to promote products or services. This is the demand side, where we pay to show ads to people.

With Google Ads, we can:

• Choose goals like more sales, traffic, or leads
• Pick the type of ads: search ads, display ads, shopping ads, or YouTube ads
• Add details like product info or links to landing pages
• Google AdSense is for publishers who allow ads on their websites or apps

This is the supply side, where content owners make money by showing our ads.

With Google AdSense, publishers can:

• Pick where ads go on their content
• Choose what kind of ads to allow or block
• Use tools to test and improve ad placement

Google also has:

• AdMob for mobile app ads
• Ad Manager for managing direct and network ads
• Why Google Ads is Great

Google Ads offers many benefits:

• It has a wide reach
• It includes different ad types
• It works with other Google tools and products

About 77% of all PPC ads are run through Google Ads. This is because Google makes most of its money from ads, so it supports this platform across its services.

Examples:

• Search Ads: Show up on Google’s results pages when people search for products
• Display Ads: Appear on websites and apps in Google’s Display Network
• Shopping Ads: Appear in search results when people look for things to buy

Google Ads also includes tools to help us run better campaigns:

• Performance Max: Uses AI to test and improve ads across Google platforms
• Demand Gen: Lets us control image and video ads in Google Discover, Gmail, and YouTube Shorts

Other helpful tools in Google Ads:

• Use the Keyword Planner to find useful search terms
• Conversion tracking to see what works
• Billing tools to manage our ad spend
• Data Manager to connect Google Ads with other tools

To see these, go to “Tools” > “Data Manager” in our Google Ads account.

• When to Use Meta Ads

Meta ads work well when we want to reach new customers for B2C or ecommerce, especially at the beginning of their buying journey or to bring back people who have visited us before. If this is what we focus on, Meta ads can be a good choice, even with some of their downsides.

Also, even though some people worry about how clear Meta is, others have seen better results using Advantage+ targeting. This shows Meta ads can still help our social campaigns by increasing our visibility and brand awareness.

• TikTok Ads

TikTok ads are not just videos that pop up in someone’s feed.

Using TikTok Ads Manager, we can create different types of ads like:

• Image carousels
• Search-based ads
• Message-based ads
• Fun add-ons like stickers and branded effects used by creators

TikTok ads can also show up in other apps owned by ByteDance like CapCut, Lemon8, or Fizzo (some of these are only available in a few countries). There’s also Pangle, TikTok’s ad network, that shows ads in other apps.

Pros of TikTok Ads

TikTok ads are great for reaching younger users, sharing natural brand content, and working with creators. Right now, most TikTok users are between 18–34 years old—this includes Gen Z and young Millennials.

This platform is ideal if our product is made for this age group because:

• Many younger users spend less time on Meta platforms
• Gen Z often uses TikTok to search instead of Google

One special feature is the Spark Ad, which lets us turn a creator’s post into an ad instead of making our own. For example, a creator might post a funny video talking about a product like McAfee Scam Detector, and that same video can be used as an ad by the brand.

We can also connect with creators through TikTok One, which replaced the old Creator Marketplace.

Cons of TikTok Ads

A big problem for TikTok advertisers—especially in the U.S.—is the risk of a ban, which is still being talked about. Even if TikTok isn’t banned, Meta’s Reels and YouTube Shorts are getting better and may take users away. Some users have also started saying there are too many ads on TikTok, which can hurt user interest.

When to Use TikTok Ads

Since TikTok has more young users, it’s best for reaching college students and young working adults.

Also, TikTok Shop works with popular ecommerce tools like Amazon, WooCommerce, and Shopify, which helps us sell products directly to TikTok users.

TikTok ads do cost more—partly because video content takes more time to create and partly because creators now ask for higher payments to promote brands.

• Amazon Ads

Amazon Ads help us promote our products across many channels, including:

• Search and product pages on Amazon’s website
• Streaming services like Prime Video, Twitch, Fire TV, Freevee, and IMDb
• Alexa and Kindle devices
• Third-party apps and websites in the Amazon DSP network

For example, we might see a sponsored brand ad while searching for “keyboards” on Amazon.com.

Pros of Amazon Ads

The best thing about Amazon Ads is how well they work for ecommerce. They connect directly to Amazon’s store and usually lead to more purchases than average.

Even though Google makes more money from ads, Amazon Ads might work better if we’re focused on selling products. That’s because Amazon is the biggest online shopping site in the world.

Also, ads on Amazon often turn into sales quickly—even though this has gone down a bit over the years, the results are still strong.

Cons of Amazon Ads

One problem with Amazon Ads is that many advertisers use it, which makes it more competitive and costly. Because Amazon Ads often give fast results, more brands want to use it, making it harder to stand out.

This also raises the cost-per-click (CPC). From 2020 to 2025, average CPC went up 38%, from $0.71 to $0.98. Also, setting up Amazon Ads can feel complicated. They’ve added some AI tools to help, but it’s still a lot to manage.

When to Use Amazon Ads

If we sell on Amazon, using Amazon Ads is a smart move. But because there are so many options, we should test different types of ads to see what works best, so we don’t waste time or money on something that doesn’t help us.

• Pinterest Ads

With over 500 million users each month, Pinterest is not far behind Instagram. Pinterest offers different types of ads, such as:

• Regular images and videos
• Full-width video ads
• Image carousels
• Single product shopping ad
• Collections and idea pins
• Showcases
• Quiz ads

For example, a board showing Father’s Day gifts may include a mug that links to a product page.

Pros of Pinterest Ads

Pinterest Ads are great for showing products using visuals, cost less than many others, and reach users who spend more. People use Pinterest to save things they like or get ideas for what to buy or make.

Because it’s a very visual platform, users are more likely to notice products that catch their eye. The ads are also cheaper, costing around $2–$5 per 1,000 views.

What’s more, Pinterest users often spend more money. Luxury brands do very well here, and the return on ad spend (ROAS) is about 32% higher than other platforms.

Cons of Pinterest Ads

The downsides of Pinterest Ads include limited reach, slow results, and the fact that the platform isn’t mainly used for shopping. Like TikTok, many people use Pinterest to search for products—but 96% of those searches don’t include brand names.

This isn’t great if we depend on a strong brand name. But it does give smaller brands a chance to stand out, even if results can be unpredictable.

Also, Pinterest takes more time to get good results. Its system doesn’t focus much on likes or comments, which makes it harder to quickly boost a post.

The biggest challenge is that most users go to Pinterest for ideas—not to shop. So while things may be changing, Pinterest still isn’t built mainly for buying.

When to Use Pinterest Ads

Most Pinterest users are aged 25–34, and about 70% are women. If our products match these groups, Pinterest could be a great platform to use.

Also, because users go to Pinterest for ideas and not just ads, content that inspires will do better than content that just tries to sell.

• Snapchat Ads

Snapchat is very popular among Gen Z and offers many ad types:

• Short videos or images that appear in Stories or as spotlights
• Story ads that use a series of videos or pictures to tell a small story
• Collection ads to show product styles, bundles, or matching items
• Commercials that can last up to three minutes and can’t be skipped at first
• AR Lenses and Filters that let users add fun brand effects to their snaps

Pros of Snapchat Ads

Snapchat Ads are great for reaching younger people. The ad space is less crowded, and it’s easy to link ads directly to online shops.

About 65% of U.S. adults under 30 use Snapchat, and people aged 18–24 make up more than one-third of the total users. This makes Snapchat even better than TikTok for connecting with this age group.

Also, the number of advertisers on Snapchat grew by 60% in one year. This shows that their new direct-response ad tools are working well. Snapchat also works smoothly with online stores like Shopify, helping sellers boost sales quickly.

Cons of Snapchat Ads

Some issues with Snapchat Ads are rising ad costs, spending a lot on untested AI tools, and the fact that the company (Snap) is still losing money. Because more advertisers are using Snapchat, ad prices have gone up fast.

In just one year (ending Feb 2025), the cost per 1,000 views (CPM) jumped 27.6%. In the same time, TikTok’s went up by 9% and Meta’s by only 1%.

Snapchat is also building new AI tools for its Lenses. These could offer new ways to advertise—like in games—but it’s still unclear how well they will work.

They also made changes to how cost-per-action (CPA) bidding works. But since Snapchat’s reporting tools have always been a bit unclear, it’s not certain these changes will help.

Right now, Snapchat is trying many new things, but we don’t yet know which ones will truly benefit advertisers.

When to Use Snapchat Ads

If we want quick responses and sales from younger users, Snapchat can be a smart choice. Also, if we’re trying new ideas with our marketing budget, Snapchat is a good platform to test, especially since it’s working hard to grow and become profitable.

• Reddit Ads

Reddit mainly offers promoted posts that show up in user feeds. These include:

• Free-form ads with text, images, videos, or GIFs
• Image and video ads
• Carousel ads where people can swipe through different visuals
• Conversation ads that start discussions about a product or brand
• Ask Me Anything (AMA) chats that highlight products and services

Here’s an example of a promoted post seen in a Reddit feed. There are also bigger ad options, like a full “takeover” in a category or all of Reddit. A softer version is the “first view” ad, which shows first but doesn’t take over everything.

Pros of Reddit Ads

Reddit Ads are great for reaching small, highly active communities. They also cost less than ads on many other sites.

Reddit is built around user groups, called subreddits, where people gather to talk about shared interests.

Some of these groups are very specific and active, which means we can target users more accurately than we might on Facebook or other sites.

Also, ad rates on Reddit are usually cheaper. While not everyone clicks on the ads, those who do often convert well, especially if we retarget them later.

Cons of Reddit Ads

Some of the hard parts of using Reddit include understanding its culture, avoiding mistakes, and the limits of reaching large groups. Reddit has its own set of rules and behavior, often called “reddiquette.” It takes time to learn how to speak in a way that feels right for Reddit users.

If we don’t follow the tone, our ads may get ignored—or even called out. Also, broad ads that try to reach everyone often don’t do well here, because users mostly stay inside their interest groups.

When to Use Reddit Ads

Reddit’s user base is very different from Pinterest. It’s a good choice if we want to reach a younger audience, mostly male. To get the best results, we’ll need to learn how Reddit works and figure out which subreddits are the best fit for our ads. If we don’t want to put in that time, Reddit Ads may not be the right platform for us.

How to Build an Ecommerce Advertising Strategy

To create a strong ecommerce ad plan, we must first understand both what our business needs and what our customers want. Then, we need to see where those needs connect.
Here’s a step-by-step guide to get started:

1. Define Business Goals:

Before we begin a campaign, we should know what we’re trying to achieve.
Are we trying to:

• Grow our sales fast?
• Get more customers?
• Find better leads?
• Sell older products to make room for new ones?
• Get more people to know our brand?

These are all good goals, but we should focus on one goal at a time for each campaign.

2. Choose Key Performance Indicators (KPIs):

Once we know what success looks like, we can pick the right numbers (metrics) to measure it.

To track ad performance, we can look at:

• CPC & CPM: If these costs go up, it may mean others are bidding for the same space.
• CTR (Click-through rate): This shows if people are clicking—but it doesn’t always mean they’re buying.
• IS (Impression Share): A higher number means we’re beating others to get seen.
• ROAS (Return on Ad Spend): Helps us see if our ads bring in more money than we spent.

To track business success, we can look at:

• CVR (Conversion Rate): If people click but don’t buy, we may need to improve our site or offer.
• CAC (Customer Acquisition Cost): This shows how much we spend to get one new customer, including ads, marketing, and tools.
• LTV (Lifetime Value): This tells us how much money a customer may spend with us over time.

We can also use advanced metrics like LTV: CAC or LTB, which use the data above to help us understand the full impact of our ad campaigns.

3. Understand your customer journey:

Customer journeys have never been simple. Today, people still use old ways like TV and newspapers, but they also use many new things—like phones, computers, smart TVs, watches, and voice assistants.

To build a strong, long-term relationship, we need to know all the ways people interact with our brand—before and after they make a purchase.

4. Map channels to funnel stages:

The usual marketing funnel has three main parts:

• Awareness – When people first realize they have a need and start looking for help.
• Consideration – When they start comparing products and options.
• Purchase – When they finally buy something.

Each ad platform fits better with one part of this funnel. If we match our ads to the right stage, we’ll get better results. Covering all three stages helps us make the most out of our ad efforts.

5. Determine your creative strategy

The channels we choose will affect our creative style. Most ads today are visual—on apps like Instagram, TikTok, and YouTube. Even platforms like Google and Amazon rely on images and videos now. But words still matter. Clear and helpful text works well for people in the early and middle stages of the funnel. Whatever format we use—text, image, or video—we should make sure it looks good on all devices. Also, we should think about audio. Podcasts are growing fast, and many are now on video too. If we create ads that work with both sound and visuals, we can get more from each ad.

6. Choose ad budget allocation framework

Ad budgets cover more than just clicks.

We also need to pay for:

• Creating the ad images, videos, or text
• Paying influencers or partners
• Storing and using the data we collect

After that, we divide the remaining budget across different ad channels.

A good starting point is the 70-20-10 rule:

• 70% for things that already work
• 20% for new but promising ideas
• 10% for big tests or risky tactics

We can always change this if we see something working really well.

7. Review performance and iterate

In ecommerce, we can’t just launch a campaign and forget it. We must watch results, test new things, and adjust as needed. Some tools, like Google’s Performance Max or Meta’s Advantage+, make changes automatically. But they don’t always show all the data we need. So we still need to watch our campaigns and be ready to stop or change things if something isn’t working.

Targeting and segmentation tactics that work

One of the most important parts of ad success is finding the right people. But that’s not always easy. We may not know exactly who will buy, but finding new people like our past customers is the key to growing.

Retargeting strategies

Retargeting means showing ads to people who’ve already visited our site.

There are two main ways to do this:

• Pixel retargeting – We add a code to our site that tracks who visits
• List retargeting – We upload a list of contacts to the ad platform

All big ad platforms support retargeting. We follow the same steps—set goals, choose placements—but we now know more about our audience. So we can tailor the ads better.

For example:

• If someone viewed one product, show them that product again
• If they saw many items, show ads for a few of them and see which one works
• Or, create a series of ads that match different stages of the buying journey

Lookalike and custom audiences

These help us reach people similar to those who’ve bought before.

1. Lookalike audiences act like our current customers

• Found on platforms like Meta and Google
• Pinterest calls them “Actalike” audiences

2. Custom audiences come from actions users took

• Visiting our site
• Liking a page
• Signing up for something
• They can also be used in list-based retargeting

Custom audiences let us reach people based on what they do—not just who they are.

Demographic and psychographic targeting

There are two types of targeting:

• Demographic – age, income, gender, location
• Psychographic – interests, values, and lifestyle choices

Both types are useful. We get the best results when we combine them.

Example:
Let’s say we sell pet food. Our data might show that many buyers:

• Are 28–45 years old
• Live in a certain area
• Have a certain income

If we only use this, we might reach people without pets. And we might miss pet owners outside that group.

But if we also add psychographic info—like what pet pages they follow or what they search—we get a better match. Using both helps us reach people who are more likely to buy.

Intent signals and behavior-based segmentation
This means targeting people based on what they do.

Some examples include:

• What items they buy
• How often they visit a website or app
• What kind of ads they click
• What search terms they use
• Whether they buy right away or wait after adding to cart

This is different from psychographics. Psychographics are about interests. Behavior is about actions.

Google Ads, for example, has in-market segments that show us people likely to buy. This helps us aim at people ready to take action.

Start your ecommerce advertising journey

The best way to learn is by doing. Start small and try out a few campaigns. Use this guide to help you through the early steps. Once we get used to the process, we’ll know which platforms and tools work best for our goals. We can also use ad tools that manage platforms like Google and Meta together in one place to make things easier.
