## How do you launch Google Shopping and Performance Max from scratch?

### Start with the product feed and Merchant Center: without these campaigns won't run

Launching Google Shopping and Performance Max involves several mandatory stages. The critical piece is a correct product feed in Google Merchant Center: that is where Google pulls data for search cards and for the Performance Max AI. Without an approved feed campaigns won't start. At the same time you need to set up conversion tracking; without it the AI cannot learn or optimise bids toward your ROAS target. After launch, the first 2-4 weeks are the algorithm learning period: avoid sudden changes to budget or settings.

1. Open a Google Merchant Center account and verify ownership of the domain.
2. Prepare the product feed: title, description, price, availability, image_link, gtin/mpn.
3. Upload the feed to Merchant Center (via Google Sheets, XML or API) and get products approved.
4. Link Merchant Center to your Google Ads account.
5. Set up conversion tracking (purchases, carts, micro-conversions) via the Google tag or GA4.
6. Create a Standard Shopping campaign to test bids and product group structure.
7. Launch the Performance Max campaign: upload assets (texts, images, video) and set the target ROAS.
8. Wait for the learning period to end (2-4 weeks) and analyse the asset group report.

## How much does Google Shopping and Performance Max setup cost?

### Price depends on catalogue size, number of campaigns and depth of conversion analytics

Cost is made up of Merchant Center and feed setup, campaign creation and structuring, conversion analytics configuration and management every 30 days. The more SKUs and the more complex the product group segmentation, the higher the workload. The click budget is a separate item: it goes directly to Google and depends on the niche.

## How does Performance Max use Google's AI to grow sales?

### Google's AI unites all channels into one managed flow around a target ROAS

Performance Max is a campaign type where Google's AI takes your assets (texts, images, video, product feed) and independently decides who to show ads to, when and on which channel. The core is machine learning models that train on your account's conversion data. The more conversions accumulated, the more precisely the algorithm distributes the budget. The key metric is ROAS (revenue per euro of ad spend): you set the target ROAS and the AI optimises toward it. The minimum threshold for stable performance is around 30-50 conversions per month according to Google data.

## In short: what Google Shopping and Performance Max give an online store

Google Shopping puts your products with photo and price directly in search, delivering high ROAS thanks to the commercial intent of the query. Performance Max scales the result: one budget, Google's AI distributes impressions across Search, YouTube, Gmail, Maps and Display toward a conversion goal. The foundation of both formats is a correct product feed in Merchant Center and conversion analytics in place. Without a quality feed products won't be approved; without analytics the AI can't learn and optimise bids. Launch takes 1-3 weeks depending on catalogue size and account readiness.

## Frequently asked questions

### What is Google Shopping and how does it differ from regular ads?

Google Shopping is product ads with a photo, price, store name and rating directly in search results. Unlike text ads, the user sees the product visually before visiting the site, which improves traffic quality and conversions. For a store this means the people who click have already seen the price.

### What is Performance Max and what is it for?

Performance Max (PMax) is a Google Ads campaign type where Google's AI automatically shows ads across all channels (Search, YouTube, Gmail, Maps, Display) from one budget. The goal is to maximise conversions or ROAS. It is suited for scaling once basic Shopping campaigns have proved their value.

### What is a product feed and why is it so important?

A product feed is a structured file (XML, CSV, Google Sheets) with data for each product: name, description, price, availability, image, GTIN. Google uses it for Shopping product cards and to train the Performance Max AI. A poor-quality feed is the main reason for product disapprovals and low reach.

### What is Google Merchant Center and why connect it?

Google Merchant Center is Google's free platform for uploading the product feed and managing its display in Shopping and Performance Max. Without Merchant Center you cannot run product ads in Google. It also lets you monitor product approval status and fix feed errors.

### What is ROAS and how do you improve it in Performance Max?

ROAS (Return on Ad Spend) is the revenue generated per euro of ad budget. For example, a ROAS of 5 means 5 euros of revenue per 1 euro spent. In Performance Max, ROAS is improved through feed quality, correct conversion tracking, accurate audience signals and quality assets (texts, images, video).

### For which e-commerce platforms do you set up Google Shopping?

We work with WooCommerce, Shopify, PrestaShop, Magento and custom engines. Each platform has its own feed generation method: a plugin, built-in export or API integration with Merchant Center. The feed is checked against Merchant Center errors before launch, so products are not rejected.

### How many conversions are needed for Performance Max to work well?

Google recommends a minimum of 30-50 conversions per month for stable algorithm learning. With lower volume the AI does not accumulate enough data. In that case we recommend starting with Standard Shopping and scaling to PMax once history is built up.

### How does Performance Max affect regular search campaigns in the account?

Performance Max has higher auction priority for exact-match keywords already in the account. To avoid cannibalisation we set campaign-level exclusions and monitor attribution separately through search term reports. Cannibalisation shows in the reports, and we point it out. Search campaigns keep the brand and exact-match terms, PMax covers the rest.

### Is the ad budget included in your service price?

No. The click budget goes directly to Google Ads and is your expense. Our fee covers setup, campaign structuring, feed optimisation and management every 30 days. The minimum recommended click budget for Google Shopping is 300-500 euros per month. The figure is named after a calculation based on your products.

### In which languages do you manage ad campaigns?

We manage campaigns in Spanish, Russian and English, the studio's three working languages. We adapt the product feed, assets and reports to the required language. Support and communication are in your preferred language. Product names in the feed are written in the market's language rather than auto-translated.
