The Plumbing Website Checklist: 34 Things to Check Before You Spend Another Dollar on Marketing
Score your plumbing website out of 34. Based on our audit of 1,893 sites — the average scored only 57/100. Find your gaps in 15 minutes.
A plumber in Tampa was spending $3,200 per month on Google Ads and getting five leads. His competitor two zip codes over spent $1,800 and got fourteen. Same market, same services, same ad budget ballpark. The difference was not the ads. It was the website those ads sent people to.
When we audited 1,893 plumbing websites across 13 states and 69 cities, the average score was 57 out of 100. The top city, Gilbert AZ, averaged 78. The bottom city, Sugar Land TX, averaged 28. The gap between a website that converts and one that bleeds money is not subjective — it is measurable.
This checklist covers 34 specific items organized into five categories: Trust, SEO, Conversion, Technical, and Content. Score yourself one point for each item your site has. If you score below 20, your website is actively costing you customers. If you score above 28, you are ahead of most plumbing companies in America.
Print this. Check each item. Then fix what is missing before you spend another dollar on ads, SEO, or marketing of any kind.
Trust Signals (8 Items)
Trust is the foundation. A homeowner letting a stranger into their home needs to believe you are legitimate, licensed, and competent before they pick up the phone. 43% of plumbing websites in our audit were missing basic trust badges. Here are the eight trust items your site must have.
1. License number displayed on every page. Not buried in the footer in 8px text — visible on the homepage and every service page. 48% (752 sites) in our audit did not show their license number anywhere. In most states, displaying your plumbing license number is a legal requirement. Skipping it does not make you look clean — it makes you look unlicensed.
2. Insurance and bonding statement. A simple line: “Licensed, bonded, and insured” with your license number. This costs nothing to add and eliminates one of the homeowner’s top fears. Include the actual coverage amount if possible: “Fully insured with $2M liability coverage.”
3. Google reviews displayed on the website. 36% (683 sites) showed zero reviews on their site. Embed your Google reviews on the homepage, service pages, and about page. A star rating widget with review count builds instant credibility. See our full review display guide.
4. BBB or industry association badges. If you are a member of the BBB, PHCC (Plumbing-Heating-Cooling Contractors Association), or a local trade association, display the badge. These third-party validations signal legitimacy in a way that self-claims cannot.
5. Real photos of your team and trucks. Stock photos of a smiling model holding a wrench destroy trust. Homeowners can spot stock imagery instantly. Use real photos of your actual technicians, trucks, and completed jobs. The about page should feature owner and team photos with names.
6. Years in business or “established” date. Longevity signals stability. If you have been operating for 15 years, say it. “Serving [City] since 2011” is more powerful than any tagline.
7. Warranty or guarantee statement. “100% satisfaction guaranteed” or “1-year warranty on all repairs.” Homeowners fear paying for work that fails. A warranty statement reduces that fear to zero. Make it prominent — not buried in terms and conditions.
8. Trust badge strip on the homepage. A horizontal row showing: license badge, insurance badge, review stars, BBB logo, years in business, and guarantee badge. The top-scoring sites in our audit averaged 5.3 trust badges on their homepage. The bottom-scoring sites averaged 0.8.
SEO Fundamentals (7 Items)
Search engine optimization determines whether homeowners find your website at all. 47% (740 sites) in our audit had no schema markup. 53% (832 sites) had no service area pages. These are not advanced tactics — they are the baseline.
9. Title tags with city and service on every page. Each page needs a unique title tag that includes your primary service and city. “Drain Cleaning in Houston TX | [Company Name]” — not “Home” or “Services.” Title tags are the most important on-page SEO element you can control.
10. Meta descriptions written for humans. Every page needs a unique meta description between 150-160 characters that includes a call-to-action. “Same-day drain cleaning in Houston. Licensed plumber, 4.9 stars, 247 reviews. Call for a free estimate.” Google often rewrites these, but when they use yours, it is your ad copy in search results.
11. Service area pages for every city you serve. If you serve 12 cities, you need 12 service area pages — each with unique content about that specific city. “Plumber in Katy TX” and “Plumber in Sugar Land TX” should be separate pages with distinct content, not just a swapped city name. See our full guide on service area pages.
12. Individual pages for each core service. “Drain cleaning,” “water heater installation,” “sewer line repair,” and “leak detection” should each have their own page — not all lumped under a generic “Services” page. One page per service is how you rank for service-specific searches. Our SEO page guide covers the essential pages every plumbing site needs.
13. Schema markup (LocalBusiness at minimum). Schema tells Google what your business is, where it is, and what it does in a structured format. 47% of plumbing sites lack this entirely. At minimum, implement LocalBusiness schema with your name, address, phone, hours, and service area. See our schema markup guide.
14. Google Business Profile claimed and optimized. Your GBP is not technically part of your website, but it feeds your website’s search performance. Ensure categories, services, hours, and photos are current. A mismatched address between your GBP and website confuses Google. Read our GBP optimization guide.
15. Blog or resource section with 5+ posts. Search engines reward websites that publish helpful content regularly. A blog with posts like “How Much Does a Water Heater Cost in [City]” or “Signs Your Sewer Line Needs Replacement” captures long-tail traffic and builds topical authority. If you are starting from zero, aim for 5 posts in your first month.
Conversion Elements (8 Items)
Traffic without conversion is expensive vanity. These eight items determine whether a visitor becomes a phone call, a form submission, or a bounced statistic.
16. Clickable phone number on every page. Your phone number should be in the header, sticky on mobile, and wrapped in a tel: link so mobile users can tap to call. 62% of plumbing websites do not have a properly clickable phone number. See our clickable phone fix guide — it takes five minutes.
17. Contact form on at least the homepage and contact page. 45% (847 sites) in our audit had no contact form at all. A form captures leads from homeowners who prefer not to call — and homeowners who visit your site at 11 PM when your phone goes to voicemail. Keep fields minimal: name, phone, email, service needed, brief description. Read our contact form guide.
18. Online booking or scheduling option. 39% (741 sites) had no online booking. Younger homeowners (under 40) increasingly prefer to book online rather than call. Tools like Housecall Pro, Jobber, and ServiceTitan offer embeddable booking widgets. Even a simple “Request an Appointment” form counts. See our online booking guide.
19. After-hours lead capture system. 39% (615 sites) cannot capture leads after business hours. Emergency plumbing calls happen at 2 AM, not 2 PM. If your website goes silent after 5 PM, you are losing the highest-value calls in the industry. Solutions include answering services, chat widgets, SMS auto-responders, and after-hours booking forms.
20. Clear call-to-action above the fold. The first thing a visitor sees — before scrolling — should include a phone number, a “Call Now” or “Book Online” button, and a one-line value proposition. “Same-Day Plumbing in [City]. Licensed, Insured, 4.9 Stars.” Not a slider. Not a video. A clear directive.
21. Pricing information or cost guide. 79% (1,497 sites) display no pricing information. Even a “starting at” range answers the homeowner’s biggest question and keeps them on your site instead of bouncing to a competitor. Read our full analysis on pricing pages.
22. Emergency service highlighted. If you offer 24/7 emergency plumbing, it should be one of the first things a visitor sees. A red banner, a badge in the header, a dedicated emergency page — anything that says “We answer when others don’t.” Emergency calls carry the highest average ticket value in plumbing.
23. Service area clearly defined. Tell visitors exactly which cities and zip codes you serve. A map is helpful but not required. A simple text list — “Serving Houston, Katy, Sugar Land, Missouri City, and Pearland” — prevents wasted calls from outside your range and helps Google understand your geographic relevance.
Technical Requirements (6 Items)
Technical issues are invisible to most plumbing company owners but glaringly obvious to Google and to homeowners whose patience runs about three seconds.
24. HTTPS (SSL certificate) active with redirect. 60% (943 sites) in our audit either lacked HTTPS entirely or had it installed but no redirect from HTTP. A “Not Secure” warning in the browser bar kills trust instantly. SSL certificates are free through Let’s Encrypt, and every hosting provider offers one-click installation. Our security fix guide walks you through it.
25. Mobile-responsive design. Over 60% of plumbing searches happen on mobile devices. If your site does not render properly on a phone — text too small, buttons too close together, horizontal scrolling required — you are losing the majority of your potential customers. Google uses mobile-first indexing, meaning the mobile version of your site is what Google evaluates for rankings.
26. Page load time under 3 seconds. Every second of load time above 3 seconds increases bounce rate by approximately 32%. Test your site at PageSpeed Insights. Common fixes: compress images, enable browser caching, minimize JavaScript, and use a CDN. Our speed optimization guide covers the technical details.
27. No broken links or 404 errors. Run your site through a free broken link checker. Every 404 error is a dead end for both visitors and Google’s crawler. Fix or redirect broken links monthly.
28. Proper heading structure (H1, H2, H3). Every page should have one H1 tag (the page title) and logical H2s and H3s for sections. Do not use headings for styling — they tell Google the content hierarchy. A page with five H1 tags tells Google nothing.
29. Analytics and tracking installed. Google Analytics 4 and Google Search Console should be installed and monitored. Without analytics, you are flying blind — you do not know which pages get traffic, where visitors drop off, or which marketing channels actually produce leads. If you use call tracking, integrate it with your analytics.
Content Quality (5 Items)
Content is what separates a website that ranks from one that exists. The average plumbing website in our audit had thin, generic content that could apply to any plumber in any city.
30. Homepage with 300+ words of unique content. Not just a hero image and a phone number. Your homepage needs to explain who you are, what you do, where you do it, and why a homeowner should choose you — in enough detail for Google to understand and rank the page. 300 words is a minimum; 500-800 is better.
31. Individual service pages with 500+ words each. A page titled “Drain Cleaning” with two sentences and a stock photo does nothing for SEO or conversion. Each service page needs to explain the process, common causes, pricing ranges, and why your company is the right choice for that specific service. Our service page SEO guide covers the formula.
32. About page with owner story and team bios. The about page is the third most visited page on most plumbing websites — after the homepage and contact page. It should include the owner’s story, team photos, company values, and community involvement. 400+ words minimum. See our about page guide.
33. Clear unique value proposition. What makes you different from the 47 other plumbers in your city? “Quality service” and “customer satisfaction” mean nothing because everyone says them. A UVP should be specific: “Same-day service or your diagnostic fee is free” or “Background-checked technicians with live GPS tracking.”
34. Content updated within the last 12 months. A copyright footer that says “2023” tells every visitor and Google that this site has been abandoned. Update your copyright year, refresh service pages with current pricing, and add new blog posts or project photos quarterly at minimum.
Scoring Your Site
Count one point for each of the 34 items your website currently has. Here is how to interpret your score.
| Score | Rating | What It Means |
|---|---|---|
| 0-10 | Critical | Your website is costing you thousands per month in lost leads |
| 11-17 | Poor | Below the average plumbing site — major gaps in trust and SEO |
| 18-22 | Average | You match the typical plumbing site (score 57/100 in our audit) |
| 23-28 | Good | Above average — focus on conversion optimization |
| 29-34 | Excellent | Top 10% of plumbing websites — maintain and iterate |
The average site in our audit would score roughly 18-20 on this checklist. Sites in Gilbert AZ would average 26-28. Sites in Sugar Land TX would average 8-12. Where does your site fall?
The Priority Fix Order
You cannot fix everything at once. If your score is below 20, here is the order that produces the fastest return on effort.
Week 1: Trust and conversion essentials. Add your license number, make your phone number clickable, install an SSL certificate, and embed Google reviews. These four items take a combined 2-3 hours and immediately reduce the “Why should I trust this company?” friction that causes bounces.
Week 2: Core pages. Build or rewrite your homepage (300+ words), about page (400+ words), and top three service pages (500+ words each). Add a contact form to the homepage. This is the heaviest lift but produces the most SEO and conversion impact.
Week 3: Local SEO. Create service area pages for your top 5 cities, implement LocalBusiness schema markup, and optimize your Google Business Profile. These items directly affect your visibility in “plumber near me” searches and the Local Pack.
Week 4: Conversion optimization. Add a pricing page or cost guide, implement after-hours lead capture, and add online booking. These items turn existing traffic into more leads without spending more on marketing.
The Checklist Is Brutally Simple — That Is the Point
None of these 34 items require advanced technical skills, expensive tools, or a marketing degree. A plumber with a decent website builder and a weekend can implement the top 15 items without outside help.
The problem is not knowledge. It is prioritization. Plumbing company owners are busy running service calls, managing techs, and handling invoices. The website sits untouched because it feels like it is working — until you realize your competitor with 28 out of 34 items checked is booking the calls that should have been yours.
Our full audit of 1,893 sites breaks down these patterns by state and city. If you want to see how your market specifically compares, start there.
Every unchecked box on this list is a lead you are losing to someone who checked it. The checklist does not care about your excuses. Neither do homeowners.
