Whether you're launching your first product on Walmart Marketplace or scaling an established catalog, you need a Walmart advertising strategy. Walmart Connect — Walmart's self-serve advertising platform — gives third-party sellers the tools to reach millions of Walmart shoppers and compete for premium placements in search results and across Walmart.com.
This guide covers everything: how Walmart PPC works, each ad type in detail, the key metrics that matter, and a step-by-step framework for building profitable campaigns.
Walmart PPC (pay-per-click) works exactly as the name implies — you pay Walmart each time a shopper clicks your ad, regardless of whether they make a purchase. The amount you pay per click depends on the ad format you choose, how competitive your product category is, and the bids set by competing advertisers.
Walmart's advertising platform, Walmart Connect, is available to all professional Walmart Marketplace sellers. It gives sellers a self-serve interface to create and manage campaigns targeting Walmart.com shoppers — one of the highest-intent retail audiences in the world.
Walmart's ad auction is generally less competitive than Amazon's — especially outside of top categories — making it easier to achieve profitable ROAS as a new advertiser. That gap is narrowing as more sellers invest in Walmart Connect, so now is the time to build your advertising foundation.
Walmart.com receives hundreds of millions of monthly visits. Without advertising, new or lower-ranked products are effectively invisible in search results. PPC ads let you:
Walmart Connect exposes a set of campaign metrics that tell you exactly how your ads are performing. Understanding each one is essential to making good optimization decisions.
How many times your ad was displayed to a Walmart shopper. High impressions with low clicks may signal a mismatch between your ad creative and buyer intent.
Number of times shoppers clicked your ad. Walmart filters invalid or accidental clicks from your billing, typically within a few days.
Clicks ÷ Impressions. A low CTR often means your main image or title isn't compelling enough in the search results. Benchmark for Walmart: 0.3–0.8%.
Total ad spend for a given time period. Equal to the sum of all click charges across your ads. Monitor daily to avoid budget overruns.
Total product revenue attributable to your ads within Walmart's attribution window (typically 14 days after a click). This is the revenue figure used in ROAS and ACOS calculations.
Ad Spend ÷ Ad-Attributed Sales × 100. The percentage of your ad revenue that you spent on ads. Lower is more efficient. Your break-even ACOS equals your profit margin.
Ad-Attributed Sales ÷ Ad Spend. The inverse of ACOS. A ROAS of 4 means every $1 in ad spend generated $4 in revenue. Higher is better.
Ad Spend ÷ Total Revenue (organic + ad) × 100. The truer picture of your advertising health — as organic sales grow from ad-driven rank improvements, TACoS naturally decreases.
Before running any Walmart ads, calculate your break-even ACOS: (Price − COGS − Fees) ÷ Price × 100. This is the maximum ACOS you can sustain before your ad campaigns lose money. Keep your actual ACOS below this number.
Walmart Connect offers three main PPC ad formats. Each has different placement locations, eligibility requirements, and strategic use cases.
Single-product ads in search results and browse pages. Available to all marketplace sellers.
Banner ads featuring your logo and multiple products. Available to brand-registered sellers.
Auto-playing video ads that appear inline in search results. Highest engagement format.
Sponsored Products are the most common Walmart ad format and the best starting point for any seller. These are single-product ads that appear prominently in Walmart search results — at the top of the page, throughout the organic results, and on relevant product detail pages. They look almost identical to organic listings but are marked "Sponsored."
Walmart's algorithm selects which search queries to match your ads to, based on your listing content, category, and product attributes. No keyword research needed upfront.
You select specific keywords to bid on and set individual bids per keyword. Full control over targeting lets you optimize aggressively once you have performance data.
When using manual targeting, Walmart offers three match type options — each with a different level of reach vs. precision:
Your ad shows for searches that include your keyword in any order, along with related terms and synonyms. Maximum reach, but also the most wasted spend risk. Good for discovery.
Example: Keyword "camping lantern" → matches "best battery powered lantern for camping" and "lantern camping solar"
Your ad shows when the search query contains your keyword phrase in the same order. Other words may appear before or after. Balanced reach and relevance.
Example: Keyword "camping lantern" → matches "rechargeable camping lantern" but not "lantern for camping"
Your ad shows only when the search query exactly matches your keyword (or very close variants). Highest purchase intent, lowest volume. Best for your proven, highest-converting terms.
Example: Keyword "camping lantern" → only matches "camping lantern" and close plurals
Start with an automatic campaign to collect keyword data for 2–4 weeks. Identify converting search terms from your Search Term Report, then move them into a manual campaign with exact or phrase match for tighter ACOS control. Pause underperforming terms in the auto campaign by adding them as negative keywords.
Sponsored Brands are banner ads that feature your brand logo, a custom headline, and up to three products. They appear at the very top of Walmart search results — above all Sponsored Products and organic listings — making them the highest-visibility placement on Walmart.com.
Unlike Sponsored Products which direct shoppers to a single product detail page, Sponsored Brands can drive traffic to a custom brand landing page or a curated product collection — keeping competitors completely out of view.
Sponsored Videos are auto-playing video ads that appear inline within Walmart search results. They stop the scroll and immediately communicate product value in a way that static images simply cannot. Because video is relatively underutilized by Walmart sellers, early adopters often see disproportionately strong engagement and click-through rates.
You don't need a professional studio. Many top-performing Walmart video ads are filmed on a smartphone in good natural light. Focus on a clean background, clear audio (even if you'll mute it), and sharp product close-ups. Simple and informative beats flashy and vague every time.
Launching a campaign is easy. Launching a profitable one takes strategy. Follow this framework to maximize results from the start.
PPC can drive clicks, but a weak listing kills conversions. Before activating any campaign, make sure your product listing is fully optimized:
The keywords you target determine who sees your ads. Use WallyPilot's keyword research tools to find terms that balance search volume with realistic competition.
Walmart Connect offers several bidding modes. Your choice affects how aggressively you compete for placements:
You set a maximum bid per keyword and Walmart never exceeds it. Predictable costs. Good for tight budget control.
Walmart's algorithm adjusts your bids dynamically to maximize conversions within your target budget. Gives up some control in exchange for algorithmic efficiency.
For most sellers starting out, fixed bids give you the most visibility into what's working. Use WallyPilot's automated bid rules to scale bid management without manual effort.
Your daily budget is the maximum Walmart will spend on your campaigns in a single day. Setting it too low throttles your impressions and stunts data collection. Setting it too high burns through budget before you've identified what works.
After 1–2 weeks of runtime, you'll have enough data to make meaningful optimization decisions. Review these reports regularly:
Once you understand your campaign baselines, use automated bid rules to handle routine optimization without daily manual work. WallyPilot's automated rules can:
The most profitable Walmart advertisers don't run a single campaign type — they stack complementary campaign strategies at each stage of the funnel:
