Google Shopping & Performance MaxThat Sell Your Products, Not Waste Spend
Short answer: Google Shopping ads promote individual products with an image, price, and store name pulled from a Google Merchant Center product feed, so shoppers see the item before they click. Performance Max is a single goal-based campaign that uses your feed plus asset groups and audience signals to serve ads across Search, Shopping, YouTube, Display, Gmail, Discover, and Maps at once. Shopping campaigns give you tight control over products and search terms; Performance Max trades some control for broader reach and Google's automation. Managing both well starts with a clean, optimized feed, because the feed, not the keyword, decides where product ads show.
Feed-driven ads, run and built by one Houston team
Shopping and Performance Max live and die by the product feed. Zen in Tech treats Google Merchant Center as the foundation: accurate titles, clean images, correct product types and attributes, and supplemental feeds that fix what your platform exports badly. When the feed is right, both Shopping and PMax have something good to work with. When it is wrong, no bid strategy can save it.
We are a Houston, TX full-service agency with 20+ years of experience, 700+ projects delivered, and a 100% in-house team of 15+ specialists. That matters here because the people managing your Shopping and Performance Max campaigns sit next to the people building your product pages and landing pages. Feed, ad, and page get fixed together, not thrown over a wall to an offshore vendor.
Shopping and Performance Max live or die on your product feed and the pages behind each click, so it matters that our in-house team also builds those product pages and manages the Merchant Center feed. We tune the feed and the on-site experience together — 20+ years and 700+ projects from one Houston team, not a hand-off between an ad agency and a web shop.

How a Shopping & Performance Max engagement works
From the first feed audit to ongoing management, here is how we take Shopping and Performance Max from setup to steady, measurable performance.
1. Feed & account audit
We audit your Merchant Center feed, product data, existing campaigns, and tracking to find disapprovals, weak titles, and wasted spend before we spend a dollar.
2. Strategy & structure
We decide where Shopping and Performance Max each fit, how to segment products by margin and priority, and what target the campaigns should chase.
3. Feed & creative build
We clean up titles, images, and attributes, apply feed rules and supplemental feeds, and produce the text, image, and video assets PMax needs to perform.
4. Optimization & guardrails
We tune bids and targets, add negatives and brand exclusions, prune poor performers, and use search-term insights to protect budget as data comes in.
5. Tracking & reporting
We set conversion tracking with Enhanced Conversions and GA4, verify values, and build a Looker Studio dashboard so you see spend, ROAS, and product performance clearly.
6. Managed care
Ongoing management, feed monitoring, asset refreshes, and a real person you can reach, month over month, with no long-term contract required to start.

FAQ
Google Shopping & Performance Max FAQs
How much does Shopping and Performance Max management cost?
Our PPC management typically starts around $1,000/mo, with the exact fee depending on the number of products, campaigns, and how much feed work is involved. Your ad spend is separate and paid directly to Google. We confirm scope and pricing on a free call, with no long-term contract required to start.
What is the difference between Google Shopping and Performance Max?
Google Shopping campaigns show individual products from your feed and give you tight control over which products run and where. Performance Max is one goal-based campaign that uses your feed, asset groups, and audience signals to serve ads across Search, Shopping, YouTube, Display, Gmail, Discover, and Maps at once. Shopping favors control; Performance Max favors reach and automation. Many stores run both, and we help you decide the right mix.
How soon will I see results from Shopping or Performance Max?
Shopping campaigns can start driving clicks within days of the feed being approved. Performance Max usually needs a learning period of roughly two to four weeks and enough conversion data before performance stabilizes, so we treat the first month as setup and learning, then optimize from real data rather than guesses.
How do you stop Performance Max from wasting my budget?
We add account-level negative keywords, brand exclusions so PMax is not just capturing people already searching your name, and product exclusions for low-value SKUs. We watch search-term and asset-group insights, segment products by margin, and keep the feed clean so automation has good signals to spend against instead of a blank check. A clean Merchant Center feed is the other half of the answer, since bad product data quietly burns spend.
Do you build the product and landing pages too, or only run the ads?
Both, on the same team. That is our differentiator: the specialists managing your Shopping and Performance Max campaigns work alongside the people who build and improve your product pages and landing pages. When conversion rate or feed data points to a page problem, we fix it in-house instead of blaming the site.
Can you manage Shopping and Performance Max if I am outside Houston?
Yes. We serve clients across all of Texas, the USA, and internationally. Shopping and Performance Max are managed entirely through Google Ads and Merchant Center, so location is no barrier, and we handle onboarding, reporting, and check-ins remotely for clients well beyond Houston.
Do you manage Shopping ads for Houston businesses?
Yes. Zen in Tech is based in Houston at 9800 Richmond Ave in the Westchase and Energy Corridor area, and we work with Houston product retailers and e-commerce brands directly. Being local means we can meet in person, and it means your feed, ads, and product pages are handled by one in-house Houston team.
What tools do you use to track and report on performance?
We use GA4 and Google Tag Manager for measurement, Enhanced Conversions to improve conversion accuracy, and Looker Studio for reporting. You get a clear dashboard showing spend, ROAS, conversions, and product-level performance, so you always know what your budget is doing rather than guessing between monthly emails.
