What we do

Built around the exact part.

A driver does not want a brake pad. They want the one that fits their car. Every title, keyword and landing page is built to answer that search first time.

01Product data

Make, model and part number in the title

Titles rebuilt with brand, part type, the vehicles it fits and the manufacturer part number. GTINs and MPNs are checked on every product, so Shopping can match the exact search, not just the general one.

  • Fitment in titles and descriptions
  • MPNs and GTINs checked
  • Supplemental feed when the store cannot change
02Search

Part numbers and fitment searches

Search campaigns built around part numbers, vehicle models and the faults people describe when something goes wrong. Ads land on the page for that vehicle, so the buyer sees the right part straight away.

  • Part number and model ad groups
  • Dynamic Search Ads for long catalogues
  • Weekly search term clean up
03Structure

Budget by margin, not by menu

Parts are grouped by what they earn and how often they sell. Best sellers and high margin lines get the budget, while low margin, high volume parts get tighter targets so they do not drain it.

  • Target ROAS by product group
  • Brand kept apart
  • Microsoft Ads built on the same structure

Its best month, outside any season

$78,913Best month value
$5,742Best month spend

The account's best complete month came in March, when $5,742 of spend returned $78,913. March sits outside any seasonal peak, which makes it the cleaner evidence of what the work on the account itself is doing.

What usually goes wrong

Where car parts budgets leak.

Large catalogues and exact searches make car parts accounts easy to waste money in. These four come up most.

01

Titles without the vehicle

A title that names the part but not the cars it fits shows for broad searches and misses the exact ones. Fitment and part numbers in the title decide whether Shopping reaches buyers or browsers.

02

A huge catalogue on one bid

Thousands of parts in one product group means best sellers and slow lines share one target. Splitting by margin and sales history puts the budget where it returns most.

03

Returns from the wrong fit

A part that does not fit comes back, and the sale Google counted is gone. Clear fitment on the landing page cuts returns and makes the conversion data worth bidding on.

04

Trade and DIY buyers mixed

Garages and home mechanics search differently and buy in different volumes. Mixing them hides which audience is profitable, so trade enquiries and retail orders are tracked and reported apart.

The first month

The first month, in order.

Product data first, because in car parts the title decides the search. Budget only grows once the feed can carry it.

Week 1

Audit feed and tracking

Merchant Center issues, identifiers, fitment data and purchase tracking checked against real orders.

Week 2

Rebuild titles and identifiers

Make, model, part type and part numbers added at source or in a supplemental feed.

Week 3

Restructure by margin

Shopping and Performance Max split by what parts earn, with part number Search built alongside.

Week 4

Scale what sells

Budget moved in measured steps to the parts and campaigns that return most, Microsoft Ads included.

Questions

Before you ask.

Our catalogue has thousands of parts. Where do you start?

With the lines that already sell and the ones that spend without selling. We fix titles and identifiers for those first, group products by margin, and work outwards through the catalogue, so the biggest gains come early rather than late.

Can you add fitment data without changing our website?

Often, yes. Where the store cannot change its product data, titles and attributes are rewritten in a supplemental feed in Merchant Center. One parts supplier we run had no back-end site access, and every feed fix went through that route.

Is Microsoft Ads worth it for car parts?

It can be. Microsoft Ads reaches people who search on Bing, and Shopping and Search campaigns can be imported from Google Ads as a starting point. We test it against the same profit targets and keep it only if it returns.

When is peak season for car parts?

It depends on the range. Batteries and wipers tend to follow cold, wet weather, while other parts sell steadily all year. The best month in the car parts account we run was March, outside any season, so budgets are planned from your own sales history.

Do you work with trade customers and garages?

Yes. Trade and retail buyers are tracked and reported separately, with their own campaigns where volume justifies it. Trade enquiries can be imported as offline conversions, so bidding learns from accounts that order, not just from form fills.
