Short version: Home improvement and DIY is a spec-driven, project-based category where buyers research hard before they buy, search by exact dimension and part number, and split into two very different audiences: professionals who reorder in volume and consumers doing a one-off project. Win here by building a feed rich in specs and dimensions, structuring campaigns to serve pros and consumers differently, respecting the bulky-shipping economics that decide profit, and moving with the seasonal project calendar. Do that and you capture buyers at the precise moment their project reaches the purchase step, which is where this category is genuinely won.
DIY e-commerce does not behave like fashion or grocery. Purchases are tied to projects, so the journey is long and research-heavy, and by the time someone is ready to buy they often know the exact size, spec, or part they need. Products are frequently large and heavy, so shipping cost is a first-class part of the margin rather than an afterthought. And the customer base is genuinely two audiences in one account: tradespeople buying to work and homeowners buying to fix. The stores that win map their whole account to how projects and buyers actually move, instead of treating every click as the same shopper.
Why Google Ads works for home improvement and DIY
This category has some of the sharpest purchase intent in retail. Someone searching "18mm oak veneer plywood 8x4" or "moen 1225 cartridge replacement" is not browsing, they know exactly what they need and are ready to buy it now. Search and Google Shopping meet that specificity precisely: the buyer types a spec, and your product with the matching dimension and price appears. Because the query is so exact, the conversion rate on well-matched traffic is high and the waste on poorly-matched traffic is brutal, which makes feed accuracy the whole game.
The category also rewards being present across the project journey. A person planning a bathroom renovation researches for weeks, then buys tiles, fittings, adhesive, and tools in a burst. Being visible when the research turns into purchase, and being the store that clearly has the right spec in stock, is what converts a long consideration into a sale. Google Ads is the most direct way to be there at that purchase moment.
Specs and dimensions: the feed that wins the search
In DIY the product feed is your real campaign, because buyers search on specifications and Google can only match you if those specs are in the feed. A feed missing dimensions, materials, and part numbers simply will not show for the exact-spec queries that convert best. This is the single biggest lever in the category. The feed work that moves the needle is:
- Put dimensions and specs in the title. "M8 x 50mm Stainless Steel Hex Bolt, A2, Pack of 25" beats "Hex Bolt". Size, material, grade, and pack quantity are what people search.
- Include part numbers, model numbers, and compatibility. Buyers replacing a component search the exact part or the model it fits, so that data has to be in the feed and title.
- Fill technical attributes fully. Material, colour, size, and any category-specific specs let Google match you to precise queries and keep you eligible in Shopping.
- Reflect pack sizes and units clearly. A pro buying a box of 100 and a homeowner buying one need different listings, and the feed should make the quantity and price-per-unit unambiguous.
- Keep price and stock exact. Spec buyers abandon instantly on a mismatch, so price and real-time availability accuracy protect both conversion and Shopping approval.
The feed is the foundation the entire account depends on, and in this category the payoff for getting it right is unusually large. We cover the principle in depth in the product feed most accounts ignore, and where Shopping budget quietly bleeds when the feed is weak in why Shopping campaigns bleed money.
Campaign structure for a home improvement account
A clean structure separates traffic by intent, buyer type, and value so budget flows toward high-intent spec searches and the audiences that actually convert. Here is the structure that works across most DIY accounts.
| Campaign | Purpose | Why it is separate |
|---|---|---|
| Brand Search | Capture people searching your store name | Cheap, high-converting, must not be diluted by PMax |
| Performance Max (core) | Drive the bulk of non-brand revenue | Feeds Shopping, Display, YouTube from your catalogue |
| Non-brand Search (spec terms) | Exact dimension, part, and model queries | High intent, needs tight keyword and negative control |
| PMax or Shopping (trade or bulk) | Serve professional and bulk buyers separately | Pros reorder in volume and justify their own budget and bids |
The most important structural decision is stopping Performance Max from spending your budget on brand searches you would have won for free, then taking the credit. Adding brand exclusions to PMax and running a dedicated brand campaign is one of the highest-return changes in the whole account.

Pro versus consumer: two buyers in one account
The defining challenge of this category is that the account serves two audiences with almost opposite economics. Tradespeople buy in volume, reorder constantly, know exactly what they want, are price-sensitive on unit cost, and are worth far more over time than any single order suggests. Consumers doing a one-off project research longer, need more reassurance, buy in small quantities, and rarely come back for the same thing. Treating them as one audience with one bid and one message leaves money on the table with both.
The practical answer is to separate them wherever the data allows. Bulk and trade-oriented terms, pack quantities, and account-level offers speak to pros, while how-to reassurance, small quantities, and project-completeness speak to consumers. Custom labels in the feed can segment products by pro or consumer appeal so Performance Max and Shopping can be steered accordingly. Recognising that a pro buyer's first order is the start of a long, high-value relationship also changes how aggressively you can bid to win them, in a way that a flat first-order view of the account would never justify.
Bulky shipping and seasonality
Home improvement products are often large, heavy, and awkward, so shipping cost is not a footnote, it is central to whether an order is profitable. A cheap item with expensive freight can be a loss, while a heavy high-value item can carry its shipping easily. That reality has to live inside the account: bid harder where the product value absorbs the freight, be cautious where shipping approaches the item price, and use free-shipping thresholds and bundles to lift orders above the point where freight eats the margin. A specialist here always judges a campaign on landed cost, not click cost, because in bulky categories the shipping line decides profit.
Seasonality is the other force. Demand follows the project calendar: outdoor, garden, decking, and paint surge in spring and summer, insulation and heating-related products rise as winter approaches, and major DIY spikes cluster around long weekends and holidays when people take on projects. The account has to move ahead of that curve, ramping budget on seasonal ranges before demand peaks and pulling back before it fades, and never judging a seasonal product's ROAS on an annual average. Decking that returns strongly in May and barely sells in December is a spring product, and the budget should treat it that way.
Keywords and negatives for DIY search
For the Search campaigns that sit alongside Shopping and PMax, the winning keywords are exact and commercial: product plus dimension ("12mm plasterboard 2400x1200"), part or model number ("bosch gsb 18v-55 replacement chuck"), and application plus product ("exterior wood paint slate grey"). Broad terms like "tools" or "paint" burn budget on undecided browsers and cost far more than they return.
Negatives are heavy in this category because DIY generates an enormous informational and hire audience. Build lists from day one that exclude "how to", "tutorial", "guide", "hire", "rental", "repair service near me", "installation service", "jobs", "salary", "free", and product types you do not stock that share a word with yours. In DIY, unmanaged broad and PMax traffic drifts toward people researching how to do the job, or looking to hire a tradesperson rather than buy the product, almost immediately. A disciplined negative routine every week is what keeps a research-heavy category's budget aimed at buyers who are ready to purchase.
A realistic example
A common home improvement scenario: a building-supplies store comes in with a single Performance Max campaign showing a 3.4x ROAS and no growth. On inspection, PMax is spending a fifth of its budget on brand searches, the feed titles are generic with no dimensions or specs so the store never shows for the exact-size queries that convert, trade and consumer buyers are mixed into one undifferentiated campaign, and a large slice of spend is going to "how to" and "hire a builder" queries because there are no negatives.
The fix is not clever bidding. It is splitting brand into its own campaign and excluding it from PMax, rewriting feed titles to lead with dimensions, materials, and part numbers so the catalogue becomes eligible for spec searches, separating trade and bulk buyers so their higher lifetime value can justify stronger bids, and adding a firm negative list to cut the research and hire traffic. Once the account matches the way spec buyers actually search and recognises the value of a repeat trade customer, a stuck 3.4x becomes a scalable one. That diagnostic sequence, run before touching budgets, is the difference between a specialist and someone who just raises spend and hopes. For the ROAS math behind it, our guide on what a good ROAS is for e-commerce lays out the targets.
Common mistakes home improvement stores make on Google Ads
- Generic feed titles with no specs. If dimensions, materials, and part numbers are missing, you never show for the exact-spec queries that actually convert.
- Treating pros and consumers the same. Two audiences with opposite economics need different bids, messages, and often different campaigns.
- Ignoring shipping in the margin. Bulky freight can turn a cheap item into a loss, so campaigns must be judged on landed cost, not click cost.
- Flat budgets across the project calendar. DIY demand is seasonal, so spring, summer, and holiday project spikes need budget that moves ahead of the curve.
- No negatives against research and hire intent. "How to", "tutorial", and "hire a builder" traffic drains a research-heavy budget fast.
Frequently asked questions
How do I get my products to show for exact-spec searches?
Put the specs in the feed and the title. Buyers in this category search by dimension, material, grade, and part number, and Google can only match you if that data is there. Lead titles with size and spec, include model and part numbers and compatibility, fill every technical attribute, and keep pack sizes and units clear. A feed rich in specs is what earns the high-intent, high-converting spec queries.
How should I handle professional versus consumer buyers?
Separate them wherever the data allows. Pros buy in volume, reorder constantly, and are worth far more over time, so bulk and trade terms, pack quantities, and account offers speak to them and often justify stronger bids because of lifetime value. Consumers need more reassurance and buy small one-off quantities. Use custom labels to segment products by pro or consumer appeal and steer Performance Max and Shopping accordingly.
Does shipping cost really change my Google Ads strategy?
In this category, yes. Products are heavy and awkward, so freight is central to whether an order is profitable, not a footnote. Bid harder where the product value absorbs the shipping, be cautious where freight approaches the item price, and use free-shipping thresholds and bundles to lift orders above the point where shipping eats the margin. Always judge a campaign on landed cost rather than click cost.
How do I deal with all the how-to and DIY research traffic?
With a firm, constantly maintained negative list. DIY generates huge informational demand, so exclude "how to", "tutorial", "guide", "hire", "rental", "installation service", and similar terms from day one, and review them weekly. That keeps a research-heavy category's budget aimed at buyers who are at the purchase step rather than people learning how to do the job or looking to hire it out.
Bringing it together
Home improvement and DIY is winnable on Google Ads, but only for stores that match the way projects and buyers actually behave rather than treating every click alike. Build a spec-rich feed so you show for exact-dimension searches, structure the account to serve pros and consumers on their own terms, price every campaign on landed cost including bulky freight, and move with the seasonal project calendar. Do that consistently and you capture buyers at the precise purchase moment, which is where this category is won. For the wider picture, our e-commerce strategy guide ties it together.
