Launching Google Ads for an Online Store: Merchant Center, Search, Performance Max, Analytics


Google Ads is one of the most stable and scalable sales channels for online stores. Real results appear only when Google Merchant Center, search ads, analytics, and e-commerce events are set up correctly. This article provides a detailed, practical, and extended guide for launching Google Ads for online stores, focusing on automation and the built-in capabilities of the Hotlist.biz platform.

1. Types of Google Ads for Online Stores

1.1 Google Shopping (Product Ads)

Google Shopping is a key sales channel for e-commerce. Ads appear directly in search results and include:

  • product images
  • title
  • price
  • availability
  • store name

This format generates highly targeted traffic with high conversion. Without Google Merchant Center, product ads cannot run.

1.2 Search Ads (Contextual Ads)

Search ads are used for:

  • product categories
  • high-margin items
  • brand-specific queries
  • competitive niches

Example queries:

  • "buy sneakers"
  • "laptop price"
  • "online electronics store"

1.3 Performance Max

Performance Max combines multiple channels simultaneously:

  • Google Shopping
  • Search
  • Display
  • YouTube
  • Discover

This campaign type works only with correct analytics and e-commerce event tracking.

2. Google Merchant Center — the Foundation of Product Ads

2.1 What is Merchant Center?

Google Merchant Center is an account where all product data is stored:

  • titles and descriptions
  • prices
  • availability
  • attributes

Google does not take products directly from the website — it uses a product feed.

2.2 Mandatory Google Requirements

  • HTTPS
  • "Payment & Shipping" pages
  • "Privacy Policy"
  • "Contact Information"
  • accurate prices and availability

2.3 Product Feed

Minimum required attributes:

  • id
  • title
  • description
  • link
  • image_link
  • price
  • availability

For advanced campaigns, additional parameters are used: brand, gtin, mpn, size, color, material, etc.

3. Advanced Product Feed on Hotlist.biz

The Hotlist.biz platform provides a built-in, correct, and extended product feed for Google Merchant Center.

Implemented features:

  • automatic XML feed
  • correct Google attributes
  • price and availability updates
  • support for product variants
  • support for product attributes

Important: Hotlist.biz allows specifying product type at the category level. For example:

  • Category "Sneakers" → product type "Shoes"
  • Passing the size parameter
  • Google understands this as shoes with a specific size

4. Google Search Ads

4.1 Correct Account Structure

  • separate campaigns by category
  • separate campaigns by brand
  • division by margin

4.2 Common Mistakes

  • running ads without analytics
  • no conversion tracking
  • all products in one campaign
  • missing negative keywords

5. Analytics — the Foundation of Ads

5.1 Why Ads Don’t Work Without Analytics

  • Google algorithms do not learn
  • cannot optimize bids
  • no understanding of real performance

5.2 Google Analytics 4 for Online Stores

GA4 should track:

  • view_item
  • view_item_list
  • add_to_cart
  • begin_checkout
  • purchase

6. Quick Analytics Setup on Hotlist.biz

The Hotlist.biz platform offers a fast built-in method to connect:

  • Google Analytics
  • Google Tag Manager

Setup is done through the admin panel without editing code. All key e-commerce events are sent automatically.

7. Google Tag Manager and Ad Events

GTM is used to:

  • manage events
  • connect ad pixels
  • flexible setup without code edits

8. Linking Google Ads + Analytics + Merchant

  • Google Ads ↔ GA4
  • Google Ads ↔ Merchant Center
  • Merchant Center ↔ website

On Hotlist.biz this integration works out-of-the-box.

9. Typical Google Ads Launch Workflow

  1. Prepare the online store
  2. Connect analytics

10. Why Platform/CMS Matters

Even perfectly set ads cannot fix:

Hotlist.biz is designed from the ground up to be ready for ads, SEO, and scaling.

Effective Google Ads is a system, not a single "Launch" button. Using Hotlist.biz, your store gets a ready infrastructure for running product and search ads without technical risks.
