Shopping ads put your products, prices and photos in front of people ready to buy. Lead Gems is a UK Google Shopping agency that fixes the product feed first, then runs campaigns measured by profit, not just revenue.

- Profit by product
What does a Google Shopping agency do?
A Google Shopping agency manages your Google Merchant Center account and product feed, and builds the Shopping and Performance Max campaigns that show your products on Google. It improves product titles, images and data, controls which products get budget, and reports on revenue and profit. As your Google Shopping agency, Lead Gems works from your margins, not just your sales, so budget goes where it earns money.
"We did not spend a penny more on ads. We just stopped wasting the clicks we were already paying for."
The problem
Why Google Shopping campaigns waste money
Shopping looks simple: upload products and pay per click. The details of the feed and the campaign set-up decide whether it makes money.
The product feed is poor
Weak titles, missing data and low-quality images mean products appear for the wrong searches, or not at all.
Every product gets the same budget
Best sellers and loss-makers share one pot, so winners are starved and losers keep spending.
Products are disapproved
Merchant Center errors on shipping, returns, price or identifiers quietly stop products from showing.
Margins are ignored
A campaign with a good return on ad spend can still lose money once cost of goods, delivery and returns are counted.
Search terms are not controlled
Without negative keywords and structure, ads appear for searches that never convert.
Reports show revenue only
Revenue is easy to report. Profit by product is what decides what to scale.
The difference
How Lead Gems compares to a typical Google Shopping agency
Many Shopping agencies run one campaign and report one number. We manage the feed, the structure and the margin.
| Area | Typical Google Shopping agency | Lead Gems |
|---|---|---|
| What they measure | Return on ad spend and revenue | Profit by product, after cost of goods and delivery |
| Product feed | Pulled from the shop as it is | Titles, descriptions, images and attributes improved |
| Campaign structure | One campaign for everything | Products grouped by margin, demand and stock |
| Merchant Center | Checked when something breaks | Monitored for disapprovals, price and stock mismatches |
| Search terms | Left to Google | Reviewed weekly, with negatives and controls |
| Reporting | A monthly PDF of revenue | A live dashboard showing profit, cost per order and top products |

Our approach
How our Google Shopping agency approaches campaigns
Shopping runs on product data. We start with the feed, then build campaigns around what makes money.
- 01
We fix the feed first
Titles, images, categories and attributes are improved, because the feed decides which searches your products can win.
- 02
We work from your margins
We group products by profit and demand, set targets from real margins and move budget toward what pays.
- 03
We keep Merchant Center healthy
We watch for disapprovals and mismatches between your feed and your site, and fix them before sales are lost.
- 04
We join Shopping to the rest of Google
Shopping, search, remarketing and video share data in one account, so each supports the others.

We manage the feed and the campaigns, and connect them to your shop and your reports.

Why profit matters more than return on ad spend
Return on ad spend divides revenue by ad cost. It ignores the cost of the product, delivery, returns and payment fees. A campaign can show a healthy return and still lose money.
We ask for your margins by product or category, set a target return that leaves a profit, and report on what is left. That is how we decide which products to scale, and which to stop advertising.

Search volume is small. Most retailers find a specialist through referral or a problem with their feed. We write for the question they ask.

Questions
Google Shopping Ads questions, answered.
What is Google Shopping?
Google Shopping shows products with a photo, price and shop name directly in Google results. You pay when someone clicks, and the listings come from your product feed in Google Merchant Center.
What is Google Merchant Center?
Merchant Center is the Google account where you upload and manage your product data. It checks your products against Google’s rules and feeds them to Shopping ads and free listings.
Who is Google Shopping for?
Businesses that sell products online, including online retailers and brands. If you sell services, search and local campaigns are usually the better fit, and we will tell you so.
How much does Google Shopping cost?
You set your budget and pay when someone clicks. Cost depends on your products, prices and competition. In your free audit we show what budget would suit your margins.
Why are my products not showing?
The usual causes are disapprovals for missing data, price or stock mismatches with your website, or shipping and returns settings that are incomplete. A feed audit finds them quickly.
Shopping campaigns or Performance Max?
Standard Shopping gives more control, and Performance Max reaches more places. Many accounts run both, with controls so budget goes where it earns a profit.
Do you work with Shopify and WooCommerce?
Yes. We connect Merchant Center to the main shop platforms and keep the feed in step with your site.
What is a good return on ad spend?
It depends on your margins. A return that looks good can still lose money once product cost and delivery are counted, so we set the target from your numbers.
Will I own my accounts?
Yes, always. Your Merchant Center, Google Ads account and data belong to you, and you keep full access whether you stay with us or not.
Should I run Shopping and search ads together?
Usually, yes. Shopping catches people comparing products, and search catches people looking for a brand or a category. Tracked together, you see which earns more.
