Google Vehicle Ads are one of the most effective advertising channels available to UK car dealers. As we showed in our benefits guide, one dealer achieved 23.9k visitors, 1.66 million impressions and 350 conversions in just three months. But getting to that point requires a properly structured setup.

This guide walks you through the complete setup process — from building your vehicle feed to launching your first campaign.

Prerequisites

Before you begin, ensure you have the following in place:

  • A dealer website with individual vehicle pages — each vehicle needs its own URL that matches the feed data
  • A Google Ads account — this is where your campaigns will be managed
  • A Google Merchant Center account — this is where your vehicle feed will be submitted
  • High-quality vehicle images — Google requires clear, well-lit photos
  • Accurate stock data — prices, specifications and availability must be current

If you are using Haswent’s dealer website and DMS, most of these prerequisites are already handled — your vehicle pages exist, images are uploaded and stock data is maintained centrally.

Step 1: Build Your Vehicle Feed

The vehicle feed is the foundation of your Vehicle Ads campaign. It is a structured data file that tells Google everything about each vehicle in your stock. Google accepts feeds in XML, TSV (tab-separated values) or Google Sheets format.

Required Feed Attributes

Every vehicle in your feed must include:

vehicle_typeType of vehiclecar

Recommended Feed Attributes

These are optional but improve ad performance:

  • body_style — saloon, hatchback, SUV, estate, etc.
  • fuel_type — petrol, diesel, electric, hybrid
  • transmission — manual, automatic
  • trim — M Sport, S Line, R-Line, etc.
  • number_of_doors — 2, 3, 4, 5
  • engine_size — 2.0L, 1.5L, etc.
  • additional_image_link — up to 10 additional images

Finance Attributes (FCA-Registered Dealers)

If you are FCA-registered and want to display finance pricing:

  • monthly_payment — the representative monthly payment
  • deposit — the required deposit amount
  • loan_term — number of months
  • annual_percentage_rate — the representative APR
  • downpayment — initial payment if different from deposit

Feed Quality Tips

  • Keep prices accurate — the price in your feed must match the price on your vehicle detail page. Mismatches will cause disapprovals.
  • Use high-quality images — at least 800x600 pixels, well-lit, no watermarks, plates or overlays
  • Update frequently — ideally every few hours. Sold vehicles should be removed promptly
  • Include all required fields — missing attributes are the most common cause of feed rejection

With Haswent, your vehicle feed is generated automatically from your DMS data. We validate attributes, enrich specifications and schedule feed updates to keep your ads current.

Step 2: Set Up Google Merchant Center

Google Merchant Center is the platform that receives and validates your vehicle feed before distributing it to Google’s advertising surfaces.

Account Creation and Verification

  1. Create a Merchant Center account at merchants.google.com
  2. Verify and claim your website — this proves you own the domain your vehicle pages are hosted on. Methods include HTML tag, Google Analytics, Google Tag Manager or DNS record
  3. Provide business information — business name, address, phone number and customer service contact
  4. Accept the terms of service — including vehicle ads-specific policies

Submitting Your Feed

  1. Navigate to Products > Feeds in Merchant Center
  2. Click Create feed and select your target country (United Kingdom) and language (English)
  3. Choose your feed type — Vehicle inventory ads
  4. Select your input method:
    • Scheduled fetch — Google retrieves your feed from a URL at set intervals (recommended)
    • Upload — manually upload a file
    • Google Sheets — link a Google Sheets document
  5. For scheduled fetch, provide your feed URL and set the fetch frequency (we recommend every 6 hours minimum)

Feed Diagnostics

After submission, Merchant Center will process and validate your feed. Check the Diagnostics tab for:

  • Item-level issues — individual vehicles with problems (missing attributes, policy violations)
  • Feed-level issues — problems affecting the entire feed (format errors, authentication failures)
  • Account-level issues — broader compliance problems

Address all errors before launching your campaign. Warnings should also be resolved where possible, as they can affect ad eligibility and performance.

Step 3: Link Google Ads and Merchant Center

Your Google Ads and Merchant Center accounts need to be linked so your vehicle feed can be used in advertising campaigns.

  1. In Merchant Center, go to Settings > Linked accounts
  2. Click Link account and enter your Google Ads customer ID
  3. The link request will appear in Google Ads — accept it under Tools > Linked accounts > Google Merchant Center

Step 4: Configure Your Campaign

With your feed approved and accounts linked, you can create your Vehicle Ads campaign in Google Ads.

Campaign Type

Vehicle Ads run through Performance Max campaigns with a vehicle feed attached. To set up:

  1. Create a new Performance Max campaign
  2. Select your Merchant Center account when prompted
  3. Select the vehicle feed as your product feed
  4. Set your campaign objective — typically Sales or Leads

Budget and Bidding

  • Daily budget — start with a budget that allows for meaningful data collection. For most independent dealers, £20-50 per day is a sensible starting point
  • Bidding strategy — begin with Maximise conversions to let Google’s AI optimise towards your goals. Once you have sufficient conversion data (typically 30+ conversions), you can switch to Target CPA for more control
  • Bid adjustments — review performance by device, location and time of day after the first two weeks

Geo-Targeting

Set your geographic targeting based on your dealership’s typical catchment area. For most dealers, this means:

  • Your local area (town or city) with higher bids
  • Surrounding areas within a reasonable driving distance
  • Exclude areas that are too far for customers to realistically visit

Conversion Tracking

Before launching, ensure your conversion actions are properly configured:

  • Phone calls — track calls from ads and from your website
  • Form submissions — enquiry forms, test drive bookings, finance applications
  • Click-to-call — mobile users tapping your phone number
  • Directions requests — users clicking for directions to your dealership

Each conversion action should be set up in Google Ads with the correct tracking code installed on your dealer website.

Step 5: Launch and Monitor

Once your campaign is live, monitor performance closely during the first two weeks:

Key Metrics to Watch

  • Impressions — how often your vehicles are being shown
  • Click-through rate (CTR) — the percentage of impressions that result in clicks. For Vehicle Ads, 1-3% is typical
  • Cost per click (CPC) — what you are paying per visitor. Vehicle Ads typically deliver lower CPCs than generic search ads
  • Conversions — enquiries, calls and other actions from your ads
  • Cost per conversion — your total spend divided by the number of conversions

Common Issues After Launch

Low impressions: Your budget may be too low, geo-targeting too narrow, or your feed may have quality issues. Check Merchant Center diagnostics.

High CPC: Review your bidding strategy and ensure your vehicle titles and images are competitive. Poor-quality images or vague titles reduce ad quality.

Low conversion rate: Check your landing pages. If visitors are arriving but not enquiring, the issue is likely with your website — page speed, mobile experience, call-to-action visibility or pricing clarity.

Disapproved vehicles: Check Merchant Center for specific reasons. The most common causes are price mismatches, missing images or policy violations.

Troubleshooting Common Feed Issues

Price Mismatch

Google compares the price in your feed to the price displayed on your vehicle page. If they do not match, the vehicle will be disapproved.

Fix: Ensure your feed and website are updated from the same data source. With Haswent, both are powered by the same DMS, eliminating this issue.

Image Quality

Images must be at least 800x600 pixels, clearly show the vehicle, and not include watermarks, promotional text, logos or dealer overlays.

Fix: Use clean, well-lit photos taken from multiple angles. Remove any overlays or branding from vehicle images.

Missing VIN

Google requires a VIN for most Vehicle Ads. If your feed does not include VINs, vehicles will be disapproved.

Fix: Ensure VINs are recorded in your DMS when vehicles are added to stock.

Sold Vehicles Still Showing

If a vehicle has sold but is still appearing in your feed, it will lead to a poor user experience and wasted ad spend.

Fix: Set up frequent feed updates (every 4-6 hours minimum) and ensure your DMS removes sold vehicles from the feed automatically.

Frequently Asked Questions

From feed creation to live ads, the process typically takes two to three weeks. This includes feed generation, Merchant Center setup, account verification, campaign configuration and Google's review process.
