The Google Ads platform includes all of the formats across Google’s ad inventory. This includes search ads, Google Shopping Ads, and display campaigns. Optimizing Google Ads encompasses every step you take behind the scenes to tailor your campaigns to better meet your intended outcomes.
According to 2025 data from Gartner, marketing budgets have been flatlining since 2021. In the face of stagnant budgets, marketing leaders are focusing on getting the most out of their spend with data and analytics tools that optimize performance. There are many levers within your Google Ads account you can pull to optimize your campaign performance, from refining your negative keywords to leaning into Google’s AI features like Smart Bidding.
Read on for specific advice on how to optimize Google Ads for ecommerce, with insights from Jaclyn VanSloten, who founded Femra Consulting to help brands get measurable return on ad spend (ROAS) from their campaigns.
What is Google Ads optimization?
Google Ads optimization is the process of refining your campaigns, keywords, bidding strategies, and brand assets to achieve better results. It includes reviewing your search terms report and Google Analytics data to evaluate and improve your ad group structure and keyword selections. Optimization helps ensure your pay-per-click (PPC) campaigns drive the right shoppers to the right product, rather than generating clicks that don’t convert.
Why it’s important to optimize your Google Ads
Ads that attract high-value customers help make your ad spend efficient and effective:
-
Lower cost per acquisition. Google rewards relevance. When your ad copy, keywords, and landing page align, Google’s reporting suggests that your Quality Score improves, which can lower your cost per click.
-
Greater visibility in Google Shopping results. Google uses your Google Merchant Center product feed, a file that holds details like titles, prices, and availability, to match your listings to user searches. Keyword-rich titles, accurate pricing, and correct Global Trade Item Numbers (GTINs) all help your products surface.
-
Better spend allocation across your product catalog. With a watchful eye on optimization opportunities, you can shift your ad spend toward top-selling stock-keeping units (SKUs) and pull back on items that rarely sell through Google Ads.

Optimize Google Ads campaigns with a mix of keyword strategy, feed quality, and realistic ROAS benchmarking. The tips below draw on Jaclyn’s experience managing Google Ads for ecommerce clients.
Use the right keyword match type for each goal
Google offers three keyword match types for search campaigns, each serving a different purpose:
-
Broad match. The widest setting, which lets Google’s algorithm interpret a user’s search intent and surface your ads for searches related to your keyword. For example, if you bid on “men’s leather boots,” broad match might show your ad for “waterproof work boots for guys” or “men’s winter footwear,” related searches you didn’t explicitly target.
-
Exact match. The tightest option, which shows your ads only for queries that match the meaning of your keyword. With the same keyword, your ad would only appear for “men’s leather boots” or near-identical queries like “leather boots men’s,” but nothing broader.
-
Phrase match. This sits in the middle, triggering your ad when a search includes the meaning of your keyword. Phrase match gives you more reach than an exact match, while still keeping the match focused. So your ad could show for “best men’s leather boots under $200” but wouldn’t fire for “men’s suede Chelsea boots,” since that changes the core meaning.
Jaclyn recommends using exact match for branded keywords and your “hero” (i.e., most purchased) products and services. She views exact match as the anchor of any Google Ads program because it delivers efficient results on terms where a user’s search intent is already clear. Your budget goes toward only the highest-intent searches, so you waste less ad spend on clicks that were never likely to convert.
She uses broad match keywords primarily as a prospecting tactic. Google recommends broad match paired with Smart Bidding, which adjusts bids based on how well a given query is likely to perform. That is, how likely the searcher is to convert, based on auction-time signals like device, location, time of day, browser, and operating system. However, Jaclyn says that this approach really only works once you have 30 to 50 conversions per month, so the algorithm has enough signals to learn from. If you’re just launching your store or still testing product-market fit, start with an exact match search campaign to build that data foundation before expanding.
Build a negative keyword strategy from day one
Adding negative keywords to your campaigns prevents your ads from appearing in irrelevant searches and cuts wasted ad spend from your Google Ads account. It should be an ongoing part of your campaign management. Jaclyn checks her search terms report within her Google Ads account two to three times a week for newer campaigns and scales back to weekly once performance stabilizes.
She also builds a negative keyword strategy at the start of every client engagement, starting with her universal negatives. These are broad, non-commercial terms like “free,” “DIY,” “tutorial,” “how to,” “jobs,” “careers,” and “salary,” which filter out people who have zero purchase intent.
Jaclyn also recommends prioritizing terms. “Some things are hard negatives, some things are soft negatives, and some things are watchlist terms,” she says. Build your base list from day one using your search terms report, and expand it over time.
Start with these common categories:
-
Industry-specific terms. Queries such as “repair manual” or “wholesale supply” signal the searcher wants something outside your direct-to-consumer offering.
-
Competitor brand names. If you don’t want to pay for clicks from people who are specifically looking for another store, add these as negatives (though some brands bid on these intentionally).
-
Informational queries. Terms like “PDF,” “template,” and “definition” tend to attract researchers rather than buyers looking to add something to their cart.
-
Price-sensitivity modifiers. Words like “cheapest” or “budget” may not align with your positioning, depending on your price point and brand strategy.
Know when to use Performance Max
Performance Max campaigns let Google automate ad delivery across search, shopping, display campaigns, YouTube, and Gmail. Launched in 2021, Performance Max replaced Google’s older Smart Shopping and Local campaign types, which were sunset by September 2022. As Google describes it, you provide your budget, business goals, and conversions that you want to measure, and Google AI will then find potential customers for your goals and serve the most appropriate ad with the optimal bid. You hand Google the creative assets and conversion goals, and its AI figures out the rest.
Jaclyn typically steers clients toward it only after their core search and Google Shopping campaigns are already strong, conversion tracking is properly firing without double-counting, and they have proven data about what works. At that point, she’ll layer Performance Max on top of existing programs rather than replacing what already works, using it for incremental reach and scale.
For earlier-stage businesses working with smaller budgets or still learning which products convert with which audiences, standard Shopping and search campaigns may cover what you need. The hands-on control is worth the extra effort when you’re still building benchmarks and learning your Google Ads performance patterns.
Optimize your shopping feed data
Your product feed lives in your Google Merchant Center. Google uses feed data to decide which queries surface your products, so the quality of that information has a direct effect on how often your listings appear and to whom.
“The quality of the feed is really, really important for these campaigns,” Jaclyn says. “That’s non-negotiable. If you want to put your time and resources anywhere, make sure that’s up to speed.” No amount of bid adjustments or audience targeting will compensate for a feed full of vague product titles or outdated pricing.
Here’s where to focus your effort:
-
Write conversational, keyword-rich product titles. Instead of “Blue Dress—Style 4402,” use “Women’s Blue Linen Midi Dress, Summer Collection” so Google can match your listing to relevant keywords people actually use.
-
Include accurate and properly formatted GTINs for every product. These standardized IDs help Google accurately identify and categorize your products, improving match quality across Google’s ad inventory.
-
Keep pricing and availability accurate and synced in real time. Mismatches between your feed and your actual product pages can lead Google to disapprove a listing, removing it from Shopping results until you fix the discrepancy and request a review.
-
Use custom labels to segment products. Separate by margin (how much profit you make on each item), seasonality, or performance tier (how consistently a product converts), so you can create separate bidding strategies for hero SKUs versus clearance items in each ad group.
-
Add detailed product attributes like material, size, color, and intended use. The more structured data Google has to work with, the better it can match your listing to a search query worth paying for.
Match your ad copy and landing page to search intent
A user’s journey from ad copy to a landing page should feel relevant. A shopper who clicks a search ad for “men’s work boots” and ends up on a homepage, featuring both women’s and men’s shoes of all types, isn’t likely to stick around. Instead, direct them to a filtered collection page for men’s work boots or a product page for men’s steel-toe PVC boots.
Jaclyn’s suggestions for landing pages include:
-
Hero SKUs. Use product pages for hero SKUs and high-intent queries (like your own “Alpine Apex hiking socks” or a stocked brand like “Yeti Rambler 26 oz”) where a shopper knows precisely what they want.
-
Product categories. Use filtered collection pages for broader category-level searches (like “organic dog treats”) for when someone is still browsing.
-
Promotions. Use dedicated landing pages for promotions or bundles (like a summer skin care set or a buy-two-get-one deal on protein powder).
“Think about it as a human,” she says. “If I’m clicking through on this, is this what I would expect to see?” Add Google ad extensions, additional pieces of information that include site links, product prices, and your phone number. They appear before potential customers click on your ad, giving you extra real estate in the results. You can surface links to related categories, your return policy, or a current sale, giving shoppers multiple relevant entry points into your store from a single ad.
Set realistic ROAS expectations by phase
Google Ad performance takes time to build. Jaclyn breaks the timeline she uses with clients into three phases:
-
Phase 1. During the first one to two weeks, performance is usually not profitable, with ROAS sitting around 0.8 to 1.5 times. “You’re kind of just paying for learning,” she says, noting that this early phase is about gathering signals on which specific products and audiences actually convert.
-
Phase 2. In the stabilization phase, roughly weeks three through six, ROAS typically climbs to the 1.5 to 2.5 times range as Smart Bidding starts finding its footing.
-
Phase 3. By weeks six through 12, well-managed campaigns can reach 2.5 to 4 times.
However, Jaclyn is clear that not every category or brand gets to Phase 3. How crowded your market is, whether your product resonates with buyers, and how well your site and tracking are set up all factor in. Set aside budget for that learning window and hold off on big changes until the system has enough data to work with.
