Most Google Ads accounts I have seen in the interior design space are losing money in a very specific way.
The clicks come in. The form fills come in. The agency reports look fine. The designer is even told things are “trending up.” But six months in, the studio is still booking the same number of real projects it was before the ads started running.
The reason is almost always the same. The account is optimized for inquiries, not clients. And in interior design, those two things are not even close to the same thing.
I learned this running paid media for DecorAid, the platform that connects homeowners with designers across the country. We were spending $1,000 a day on Google Ads, targeting only New York, focused only on high-net-worth zip codes, and the goal was 400 qualified leads a month. Within six months we were doing 200 leads a month from all channels combined, with 140 to 150 coming from paid. Not because we got lucky. Because we threw away every assumption that works in cheaper service categories and rebuilt the account around how interior design actually sells.
This is the playbook for that.
The Pinterest Problem Is The Whole Game
Interior design has the worst signal-to-noise ratio of any service category I have worked in.
When someone Googles “roofer near me,” they have a problem they need solved this week. When someone Googles “interior design,” they could be a homeowner with $80,000 to spend, an architecture student, a Pinterest browser saving inspiration for a mood board they will never act on, a real estate agent looking for staging ideas, or a 19-year-old who likes scrolling through pretty rooms before bed.
All five of those people fill out the same form.
This is why interior design CPCs look reasonable on paper but cost-per-closed-project numbers are catastrophic. A 6% form-fill conversion rate sounds healthy until you realize that 5 out of every 6 form fills are people you would never want as clients. The actual qualified-lead conversion rate in this category is closer to 1% to 2% of clicks. Which means if your CPC is $8 and your real conversion rate is 1.5%, your true cost per qualified lead is around $530, before you even factor in the close rate from there.
The agencies that fail in this niche are the ones reporting form fills as if they are conversions. The ones that succeed are obsessed with one metric only – cost per signed project – and they architect the entire account around feeding Google enough downstream data to optimize for that outcome.
We will get to how to do that. First the market context.
What The Numbers Actually Look Like in 2026
The global interior design market is sitting at roughly $138 to $154 billion this year, depending on whose research you trust, and growing somewhere between 4.3% and 5.8% annually. The US specifically is around $26.5 billion, with renovation work growing faster than new construction.
Houzz’s 2025 State of the Industry report found that 70% of interior designers reported a positive 2025 outlook despite a slight revenue dip the prior year, and they are forecasting 9% revenue growth for 2026. The interesting number though is the harder one: only 22% of homeowners hire a design professional, down from 24% two years ago. Most homeowners look at thousands of designer photos for inspiration, then take that vision to a general contractor who builds something cheaper.
That gap is the whole opportunity. The demand exists. The hiring conversion does not. Your Google Ads strategy has to be built around closing it.
Realistic CPC and CPL benchmarks for the category, based on cross-referencing WordStream’s 2025 Home & Home Improvement data with what I have seen in actual designer accounts:
- CPC range: $4.50 to $12.00 for most markets, $15 to $25 for luxury terms in NYC, LA, London, San Francisco, Miami
- Form-fill conversion rate: 3% to 7%
- Qualified-lead conversion rate: 1% to 2%
- Cost per raw lead: $80 to $250
- Cost per qualified lead: $250 to $800
- Cost per closed project: $1,000 to $5,000
The last number is the only one that matters. And it sounds expensive until you remember that the average residential project in this industry runs $20,000 to $150,000 in design fees plus furnishings markup. A $2,000 cost per closed client on a $25,000 transaction is a 12.5x return. That is not expensive. That is the math working.
The mistake is benchmarking interior design CPLs against plumbing or HVAC. Different unit economics. Different game.
What Worked on DecorAid (And Why It Still Works)
The DecorAid account was simple by design. We refused to overcomplicate it.
The strategy was three things stacked together:
First, we only bid on transactional intent keywords. Not “interior design ideas.” Not “modern living room inspiration.” Not “how to decorate a small bedroom.” Those queries pull in the inspiration crowd and burn budget on impressions that never become consultations. We bid on “interior designer NYC,” “interior design firm Manhattan,” “Upper East Side interior designer,” “luxury interior designer New York” – terms where the searcher had already decided they wanted to hire someone and was now picking who.
Second, we geo-fenced aggressively. New York only, then narrowed further to specific high-net-worth zip codes inside the city. The Upper East Side, Tribeca, the West Village, parts of Brooklyn. The thinking was simple – the platform’s price point only worked for clients with real budgets, and bidding on someone in a $400-a-month studio apartment in Bushwick was a waste of money even if they searched the right keyword. Geographic intent was a stronger signal than search intent in this market.
Third, we kept the campaign structure consolidated. One Search campaign, focused ad groups, tight match types, big negative keyword list. We were not running 47 campaigns sliced by every variable. We were giving Google’s algorithm enough volume in one structure to actually learn. Because Smart Bidding needs data density to work, and chopping your account into tiny pieces starves the algorithm.
We did run some Display campaigns alongside Search, but only for brand support showing portfolio shots of contemporary and modern interiors. Not for direct response. Display in this category is about reminding people the brand exists, not about closing them.
What made the account work though was not any of that. It was what happened after the form was submitted.
The Sales Layer Most Designers Are Missing
When a lead came in on DecorAid, the sales team called within minutes. Not “we’ll get back to you within 24 hours.” Not an automated email sequence. A human picking up the phone.
This is old-school. Most modern marketing people would tell you it does not scale. It scales fine.
The reason it works in interior design specifically is because the buying journey is messy. We saw it constantly in the data. Someone would click on a mobile ad while standing in their kitchen, fill out a form on their phone, then disappear for two days. Then they would come back from a desktop, browse three competitors, click on our ad again, and finally book a call. Sometimes they would do this five or six times before deciding.
If you wait for them to be “ready,” they are gone. The first call gets the project.
Within the first three months on the DecorAid account, this is what we figured out by looking at search query data, device data, and time-of-day data. Mobile-first discovery, multi-device decision, fast human follow-up. Once we knew that, we built everything else around it. Negatives reviewed daily. Search terms reviewed daily. Bids adjusted weekly. Landing pages tested constantly. Sales call response time treated as a critical metric.
By month six the system was doing 140 to 150 paid leads per month and the close rate was double what they were getting from any other channel.
If I were doing the same account today, the strategy would be identical. The execution would change in exactly one way – which I will get to in a minute when we talk about the single biggest thing most interior design accounts are missing in 2026.
Keywords: What To Bid On, What To Avoid
Here is the keyword framework that actually works for an interior design firm or platform.
Bid on these (purchase intent):
- “interior designer [city]” and “interior designer near me”
- “luxury interior designer [city]”
- “interior design firm [city]”
- “hire interior designer [city]”
- “[neighborhood] interior designer”
- “commercial interior designer [city]”
- “office interior designer [city]”
- “kitchen designer [city]” and “kitchen and bath designer [city]”
- “interior designer for new home build”
- “[style] interior designer [city]” – modern, contemporary, transitional, traditional, mid-century, coastal, Scandinavian
- “interior design consultation [city]”
- “[room type] designer [city]” – primary suite designer, nursery designer, etc.
Do not bid on these in paid search (use them for SEO and content instead):
- “interior design ideas”
- “modern living room ideas”
- “[style] inspiration”
- “small bedroom decor ideas”
- “how to decorate a [room]”
- “best paint colors for [room] 2026”
- “biophilic design”
- “Japandi style”
These are awareness-stage queries. They have massive volume. They will eat your budget alive in paid search and bring you almost nobody who will actually hire a designer. They are valuable for organic content because they build topical authority and pull people into your funnel over time, but in paid they are a trap.
The negative keyword list every interior design account needs from day one:
free, cheap, jobs, salary, courses, school, degree, certification, software, app, AI, virtual reality, DIY, ideas, inspiration, Pinterest, images, photos, wallpaper, magazine, blog, intern, internship, hiring, resume, portfolio template, definition, meaning, history, famous, celebrity, HGTV, show, episode, watch, download, template, render, sketchup, autocad, students, books, ebook
That is roughly 40 negatives to start. A mature interior design account will have 200 to 500 negatives. Building that list takes daily search term reviews for the first three months. There is no shortcut to it. Every account I have ever scaled in this category had someone reviewing search terms five days a week.
The Aggregator Problem and How Independent Designers Compete
If you are an independent firm, you are not just bidding against other independent designers. You are bidding against Decorilla, Havenly, and a handful of other national platforms with much bigger budgets and aggressive remarketing.
Decorilla in particular is everywhere. They have been buying paid traffic for years, they own most of the “Decorilla vs Havenly” comparison content, and they push their style quiz funnel with $159 to $2,099 package pricing that vacuums up the budget end of the market. Havenly does the same thing with a slightly different positioning. Modsy raised $70 million and shut down in 2022, leaving a hole that the others have filled. Decorist got bought by Bed Bath & Beyond and also closed in 2022.
You cannot outbid these platforms on “online interior design” or “virtual interior designer.” Do not try. Their economics work because they sell low-touch, packaged services to people who want a designed room for under $2,000. That is a different customer than the one paying you $40,000 for a full-service residential project.
Where you win is on local intent and project complexity. The aggregator can sell a quick e-design package for a single bedroom. They cannot fly to your city, walk through a 4,500 square foot home with the client, manage a 14-month renovation, source custom furniture from D&D Building, and coordinate with the architect and contractor. That work is yours. Bid on the keywords that match it – geo-locked, project-specific, style-matched – and let the aggregators have the volume play.
The other angle that works is trust signals the aggregator structurally cannot match. NCIDQ certification on your site. ASID or IIDA membership. Press mentions in Architectural Digest, Luxe, Elle Decor. Specific named portfolio projects with budget context. These signals matter enormously to a homeowner about to write a $50,000 check, and aggregators with rotating freelance designer pools cannot replicate them.
Local Service Ads For Interior Designers – Yes, This Is Real Now
Interior designers became eligible for Google Local Service Ads when Google expanded the home services category. The official LSA documentation lists “Interior Designer” by name, defined as a service provider who plans, researches, coordinates, and manages the enhancement of building interior spaces.
This changes the economics meaningfully for the right kind of designer.
LSAs charge per lead, not per click. The Pinterest browser problem disappears at the bidding layer because someone has to actively call or message to cost you anything. The Google Guaranteed badge appears on your listing with up to $2,000 in customer protection coverage, which matters in a category where trust is the primary friction. LSA placements sit above traditional Search Ads on mobile and desktop. Star ratings and review counts show directly in the ad unit.
Pricing varies by metro but most major US markets quote $40 to $120 per LSA lead for interior design.
The setup requirements – verified Google Business Profile, background checks, applicable state licensing where required, insurance documentation, active review collection – are not trivial. Designers in states with formal interior design licensure have an easier path than those in states where the title is unregulated. But for a designer doing $5,000 to $50,000 projects, LSAs are now the highest-leverage channel in the entire paid landscape, because they filter at the cost-per-lead layer instead of at the cost-per-click layer.
For ultra-luxury work where projects are $200,000+, LSAs are less of a fit. The lead volume the channel sends does not match the complexity of the sale, and the buying journey is too long for the simpler LSA conversion path. In that segment, traditional Search Ads paired with a serious sales operation are still the right play.
The real recommendation is to run LSAs in addition to Search, not instead of. They reach different parts of the funnel. LSAs catch the “I want to book a designer this week” segment. Search catches everything else.
Campaign Structure That Holds Up
For a residential interior design firm targeting one major metro, with an annual revenue between $1 million and $10 million, here is what the account architecture should look like.
Search campaigns should take 60 to 70 percent of the budget. Inside that:
A brand campaign protecting your firm name and your principals’ names. Cheap, defensive, often skipped, and people regret skipping it the first time a competitor starts bidding on their brand.
A core local campaign covering “interior designer [city],” “interior design firm [city],” and the neighborhood-specific terms. Exact and phrase match, aggressive negatives.
Style-based campaigns for each style you actually specialize in, each with matched landing pages showing portfolio work in that style. Do not run one generic style campaign with five ad groups. Run separate campaigns so you can budget them independently and the algorithm gets clean signals.
Service-type campaigns for whole-home, kitchen, bath, new construction, and renovation. Each pointed at its own landing page with project examples in that service type.
A fully separate commercial campaign if you do commercial work. Different sales cycle, different keywords, different audience. Should not share budget or signals with residential.
Local Service Ads if eligible should take 10 to 20 percent of budget, running in parallel with Search.
Performance Max is the one I am cautious about for service-based interior designers. PMax spreads budget across YouTube, Discovery, Gmail, and Display, and in a category where buyer intent is concentrated on Search, that breadth often produces top-of-funnel leads at the expense of qualified ones. Multiple practitioners on r/PPC have reported the same pattern – PMax drives form fills in service businesses, but the close rates from those form fills are dramatically lower than Search.
If you are going to run PMax, only do it after offline conversion tracking is live, you have at least 30 qualified-lead conversions per month feeding the algorithm, you are passing actual project value back to Google rather than just lead value, and you have built tight audience signals from your existing client list. Without those guardrails, PMax in this category is an expensive way to fund Google’s exploration of the wrong placements.
Demand Gen and YouTube can take 5 to 10 percent each if you have strong video assets – completed project walkthroughs, principal interviews, design process explainers. Houzz’s 2025 data showed designers who produced video walkthroughs saw 25% fewer late-stage design changes. That stat is worth featuring in ad copy because it speaks directly to the homeowner’s biggest fear – that they will sign a contract and end up with something they hate.
Display remarketing should be always on, around 5 percent of budget, segmented by what page someone visited. Kitchen portfolio viewer gets kitchen creative. Whole-home consultation page viewer gets a different message.
Landing Pages: Where Most Of The Money Is Lost
I will say something uncomfortable here. Most interior design websites are gorgeous and convert terribly.
The problem is that designers build their sites for the design press. They want the work to look magazine-quality, the photography is curated, the typography is precise, the navigation is minimal and elegant. None of that helps a homeowner who landed on the site from a Google ad with their credit card half-out.
A landing page that converts in this category does five things at minimum.
It shows portfolio work that matches the search query above the fold within three seconds of page load. Not the firm’s “favorite” work. Not the most editorially impressive shot. Work that matches what the visitor was searching for. Someone who searched “modern kitchen designer” needs to see modern kitchens. Not a Tuscan villa.
It states a price floor or starting point. This is the thing designers resist most and it is the thing that fixes lead quality more than anything else. “Full-service residential design starting at $25,000” is the single most powerful filter you can install on a landing page. It eliminates 80 percent of unqualified inquiries before the form is even seen. The remaining 20 percent are people who can actually hire you. Effective conversion rate goes up. Cost per qualified lead goes down. The fear is that you will scare off potential clients, but the data says you only scare off the wrong ones.
It uses a specific consultation offer instead of a generic “Contact Us.” “Book Your 30-Minute Discovery Call” with a Calendly embed converts two to three times higher than a generic contact form. Add qualifying questions to the booking form – project budget range, timeline, location, scope – and you have prequalified the lead before you spend a minute on it.
It loads trust signals visibly above the fold. Press mentions, certifications, reviews from named clients with project context. According to BrightLocal, 91% of consumers aged 18 to 34 trust online reviews as much as personal recommendations. Generic stars are not enough. “Sarah and David, Brooklyn brownstone renovation” is the kind of named, contextual review that converts.
It is built mobile-first because over half of interior design searches happen on mobile. Three form fields max on mobile. Tappable phone number prominent. Page must load in under three seconds.
The other thing that matters specifically in this category is a “Our Process” section. Hiring a designer is high-anxiety because the homeowner does not know what they are buying. Walking them through your process – consultation, concept, design development, procurement, installation – calms them down enough to convert. Houzz Pro’s 2026 client survey ranked process transparency as the number one factor in pro-hiring decisions for first-time clients.
The One Thing I Would Change Today
Earlier I said I would run the DecorAid account the same way today with one execution change. This is it.
Offline conversion tracking. Or, more specifically, Enhanced Conversions for Leads.
When I was running that account, we were optimizing on form fills and relying on the sales team to manually report close rates back to me. Sean, the CEO, would tell me which leads were closing and which were not. I would adjust manually. It worked, but it was lossy and slow.
Today, the right setup feeds Google directly. Every form submission captures the GCLID. The CRM tracks the lead through the pipeline. When a lead becomes qualified, we mark it. When it converts to a signed project, we mark it again with the actual project value. That data flows back to Google Ads through Enhanced Conversions for Leads, which uses hashed user data to match across devices and survives GCLID loss from iOS and ad blockers.
What this does is shift Smart Bidding’s optimization target from “form fills” to “signed projects.” The algorithm starts allocating budget toward keywords and audiences that produce closed business, not toward the keywords that produce the most inquiries. In service businesses with sales cycles longer than 30 days, this is consistently the single highest-ROI optimization available.
Agencies running this for high-ticket service clients commonly report 30 to 50 percent reductions in cost per qualified lead within 90 days of going live, because the algorithm gets fed the truth about what is working. For an interior designer with $25,000 average project values, this is more important than anything else in the account.
If you are running Google Ads for an interior design firm and you are not feeding closed-deal data back to Google, fix that first. Everything else is downstream of that fix.
The Five Mistakes I See Repeatedly
After looking at a lot of accounts in this category, the same five mistakes show up over and over.
Bidding broadly on style and idea keywords. The reddit threads on r/PPC are full of designers reporting they “got 1,000 visitors but no clients.” Almost universally the cause is broad-match bidding on terms like “modern interior design” without negatives or geo-targeting.
Treating Google Ads as a substitute for a real sales process. Daniela Furtado of Findable Digital Marketing put it well – “Google Ads don’t convert clients. Your website does the heavy lifting.” And the website cannot do the heavy lifting if the sales follow-up is slow. Speed of first call is the most underrated metric in this whole system.
Underspending and giving up too early. Smart Bidding needs data density. For most US and UK markets, designers need at least $1,500 to $3,000 per month in spend over 60 to 90 days before judging whether the channel is working. Running $400 a month for three weeks and concluding “Google Ads doesn’t work for designers” is the most common false conclusion in this category.
Skipping offline conversion tracking on long sales cycles. Already covered. The biggest mistake.
Confusing visibility with results. Buying premium directory placement on Houzz, Pinterest, or other inspiration platforms produces big impression counts but lukewarm signed-project numbers, because those audiences skew toward inspiration-seekers, not committed buyers. This is not Houzz’s fault. It is true of every visual inspiration platform. Google Search, with explicit commercial intent signals, outperforms platform advertising for designers who measure all the way through to closed revenue.
Budget Recommendations
For a residential interior design firm targeting a single major metro:
At $1,500 to $3,000 per month, run 80% Search on city and style core terms, 20% LSAs if eligible, no PMax. Manual or Maximize Clicks bidding until you have enough data for Smart Bidding.
At $3,000 to $8,000 per month, run 55% Search, 20% LSAs, 10% Remarketing, 10% YouTube or Discovery, 5% test PMax with offline conversion tracking already live.
At $8,000 to $25,000 per month, run 45% Search, 15% LSAs, 15% PMax with OCT, 10% YouTube, 10% Demand Gen, 5% Remarketing.
Above $25,000 per month and across multiple markets, mirror the scale model per metro and add national brand-awareness video on top.
For commercial interior design firms, swap LSAs for LinkedIn as a complementary channel since LSAs are less effective for commercial RFP-driven sales. But Google Search remains the foundation – facility directors and procurement managers still start their vendor research on Google.
What This Looks Like When It Is Working
A well-run interior design Google Ads account in 2026 has four characteristics.
The CPL number on the Google Ads dashboard is not the metric anyone in the company looks at. The metric everyone looks at is cost per signed project, pulled from the CRM with project value attached.
The negative keyword list is being maintained at least three times a week, ideally daily for the first three months of any new campaign.
Offline conversion data is flowing back to Google through Enhanced Conversions for Leads, with actual project values attached, allowing Smart Bidding to optimize for revenue rather than inquiries.
The sales team is calling new leads within minutes of form submission, because in a category where prospects shop multiple firms over a multi-week window, speed is the most powerful conversion mechanism in the funnel.
Get those four right and the channel works.
The interior design industry is growing. Demand exists. The constraint is converting that demand into paying clients, and that conversion happens at the intersection of paid media and sales operations – not in either of them alone. The firms that will dominate this category over the next few years are not the ones spending the most. They are the ones whose data architecture lets Google’s algorithm optimize for signed contracts rather than clicks on Pinterest dreams.
That is the difference between a marketing channel that drains your budget and one that fills your studio’s calendar twelve months out.
