How much budget do you need for Google Ads for a windows and doors business?

The recommended minimum budget for Google Ads in the windows and doors sector is €500-800/month for smaller areas and €1,200-2,500/month for big cities like Milan, Rome and Naples. With these budgets you get 20-40 qualified leads per month. Budgets under €500/month produce insufficient data to optimize campaigns effectively.

Which keywords should you use on Google Ads for windows and doors?

The best-ROI keywords for windows and doors businesses on Google Ads are those with explicit commercial intent: 'window replacement [city]', 'PVC window quote', 'window installer [area]', 'aluminum window cost', 'energy-saving windows', 'window eco-bonus 2026'. Avoid informational keywords like 'types of windows' that bring researchers, not buyers.

How long until you see results with Google Ads for windows and doors?

The first leads arrive within 3-7 days of launching the campaigns. Optimization requires 4-8 weeks to gather enough conversion data. Cost per lead stabilizes and improves between the second and third month. Don't pause campaigns in the first 4 weeks: the initial data is needed for optimization.

Google Ads or Meta Ads for windows and doors businesses: which should you choose?

Google Ads is the mandatory starting point for windows and doors businesses: it intercepts people actively searching for a quote, with conversion rates of 20-30%. Meta Ads is complementary: it builds latent demand and retargets site visitors who didn't convert. The ideal strategy uses both, with Google Ads as the priority in the first months.

Google Ads for Windows & Doors Businesses

Every day in Italy, thousands of homeowners search Google for "window quote," "window replacement" or "window installer [city]." These are people who have already decided to replace their windows — they're just choosing who to hire. Google Ads puts you in front of them at exactly that moment.

Why Google Ads is the right channel for windows and doors businesses

Unlike Meta Ads or TikTok, Google Search intercepts active demand: people who already have the problem and are looking for the solution. The conversion rate on Google Search for windows and doors businesses is 20-30%, compared to 5-15% on Meta. Cost per lead is higher, but cost per acquired customer is often lower because more quotes actually close.

Campaign structure: how to organize your account

The most common mistake is putting everything into a single campaign. The optimal structure for a windows and doors business splits campaigns by intent:

1Brand campaign: Your company name as the keyword — cheap, protects your space and captures people who already searched for you.
2Product campaign: Keywords by window type (PVC windows, aluminum windows, security doors). High commercial intent.
3Local intent campaign: 'window installer [city]', 'window showroom [area]'. Very high conversion, higher CPC.
4Eco-bonus campaign: 'window eco-bonus 2026', 'window tax deduction'. Leverages the tax incentive — often lower cost per lead.

The landing page: where you win or lose

1H1 consistent with the ad (same keyword, same message)
2Contact form visible without scrolling — maximum 3 fields (name, phone, message)
3Eco-bonus explained with savings in euros, not just as a percentage
43-5 Google reviews with real names and photos
5Before/after photos of completed jobs
6Clickable phone number at the top of the page
7Load speed under 2 seconds (use PageSpeed Insights to check)

An optimized landing page converts at 8-15%, compared to 2-4% for a generic homepage. With the same ad budget, you can get 3-4 times more leads.

✕Not tracking conversions: Install Google Ads Conversion Tracking on forms, calls and WhatsApp.
✕Budget too low for the area: Under €500/month in competitive areas, it's better to wait and increase budget first.
