Google Shopping in Burgos — Show Your Products in Google Before Your Competition

Text search ads are triggered by keywords and show headline, description and URL. Shopping ads are triggered by the relevance of the product feed to the user's search and show image, price, product name and store. In Shopping, Google decides which products to show based on Merchant Center feed data, not on keywords configured by the advertiser. That is why optimising the product feed is the most important lever in Google Shopping.

Google crosses the user's search with feed data from all active advertisers for that product category and selects which products to show based on: relevance of the product title and description to the search, feed quality and completeness, campaign performance history and bid. Unlike search campaigns, there is no keyword list the advertiser controls directly: the feed is the search selector.

Google Merchant Center is the platform where the product feed is uploaded and managed for Shopping campaigns. Without a configured and verified Merchant Center account, Shopping campaigns cannot be launched. Merchant Center requires: website verification, compliance with Google's merchant policies, an updated product feed with the correct attributes and synchronisation with Google Ads. Merchant Center errors are a frequent cause of rejected products or campaigns that do not show.

Industry studies show that the average ROAS of Google Shopping campaigns exceeds that of text search campaigns by 30–40% for e-commerce. The reason is the implicit filtering the feed does: by showing the exact product the user is searching for with image and price, users with lower purchase intent are automatically filtered out. For online stores in Burgos, this translates into a lower acquisition cost and a higher return on advertising investment.

Shopping ads communicate more information before the click than any other advertising format in Google. The user sees the product image, price, store name and in some cases product ratings. This pre-click visibility has a dual effect: it increases the quality of clicks by filtering out the uninterested, and it is compensated by a higher post-click conversion rate.

Users who search for specific products in Google are in the most advanced stage of the purchase funnel: they are ready to buy and just need to find the right store at the right price. Google Shopping appears at that exact moment, when purchase intent is at its highest. For an online store in Burgos with products that have Google demand, this represents an acquisition opportunity at the point of highest conversion probability.

We verify domain ownership, configure shipping and returns according to the store's policies, link the account to Google Ads and verify that the data complies with Google's merchant policies. Account or product rejections are one of the most frequent problems in Shopping and are usually due to incorrect Merchant Center configurations that can be prevented with a professional initial setup.

The feed is the heart of Google Shopping. A well-optimised feed can double campaign performance compared to a generic one exported directly from WooCommerce or Shopify without optimisation. The most critical attributes are the product title (Google uses it as the primary keyword), description, image, price and category. We optimise each of these attributes to maximise relevance to searches by potential buyers.

Campaign structure in Google Shopping determines the level of control over bids and budget distribution by category or product. In standard Shopping we can segment by categories, brands or price ranges to assign differentiated bids according to each product's margin. Performance Max combines Shopping with Display, YouTube and Search in a single AI-managed campaign.

In standard Shopping campaigns, product subdivision segmentation allows assigning different bids according to category, brand, price range or profit margin. This segmentation is critical for profitability: it makes no sense to bid the same for a product with 5% margin as for one with 40% margin. We structure campaigns so that the highest-margin products receive the highest bids.

A quality feed has: all mandatory attributes correctly filled, prices and availability updated in real time or daily, high-resolution images on white or neutral background, titles optimised for buyer searches, and Google product categories correctly assigned. A feed with frequent errors in Merchant Center is the clearest signal that Shopping performance is not optimal.

The product title in Shopping must answer the question "what is the user searching for who we want to see this product?". Include in the first 70–80 characters the most searched attributes: product type, brand, model, colour, size or measurement, and any attribute that is a frequent search criterion in your category. It is not the product title from the store page: it is the text Google will use to trigger the ad.

Images in Google Shopping are the factor with the greatest influence on CTR, even above price in many categories. Google has minimum technical requirements (minimum resolution 100x100 px, no watermarks or overlaid text), but the difference between low and high CTR is usually in real image quality: white or neutral background, well-lit product, no decorative frames, showing the product from the most informative angle.

Google penalises with product rejections and can suspend Merchant Center accounts if feed data does not match the product landing page. Price, availability and shipping conditions must be updated in real time or as frequently as possible. For stores with changing inventory, we recommend automatic feed updating via API rather than periodic manual updates.

An online sports equipment store distributing in Castile and León came to us with Shopping campaigns delivering ROAS of 2.8. After optimising the feed (titles, images, categories and prices updated in real time), restructuring campaigns by product category and applying differentiated bids by margin, ROAS reached 8.1 at 3 months. With the same budget, the store was generating nearly 3 times the return on its advertising investment. [See full case →](/casos-reales)

A craftwork and home décor store in Burgos had standard Shopping campaigns with stagnant results for months. We migrated to a combined strategy of standard Shopping for highest-margin products and Performance Max for the full catalogue, with differentiated asset groups by category. Within 60 days, sales from Google Ads tripled without increasing the budget. [See full case →](/casos-reales)
