A Step-by-Step SEO Audit Framework Built for Plumbing Businesses

This audit framework is built for plumbing business owners and operators who want a clear picture of why their website isn't generating consistent leads from Google—and what to do about it.

You don't need to be a technical expert to work through most of this. The process is structured so you can identify the highest-impact problems yourself, then make an informed decision about which fixes to handle in-house versus handing to an SEO professional.

This framework is most useful if you're in one of these situations:

• You've invested in a new website but aren't seeing traffic or call volume from organic search
• You rank for your business name but nothing else—no service terms, no city-based searches
• A competitor recently passed you in local rankings and you're not sure why
• You're evaluating an SEO agency and want to understand what a real audit should include
• You're doing SEO yourself and want a diagnostic checkpoint before building out more content

What this audit does not replace: a full technical audit by an SEO specialist, a link profile analysis requiring paid tools, or a penalty recovery assessment. If your site has seen a sudden traffic drop, or if you've received a manual action notice in Google Search Console, those situations call for professional review rather than a self-assessment walkthrough.

Work through each layer in order. Technical issues can mask content and local problems—fix the foundation first before drawing conclusions about why your rankings are stuck.

Technical SEO isn't glamorous, but a site with crawl errors, slow load times, or broken mobile layouts will underperform regardless of how strong the content and local signals are. For plumbing businesses, mobile performance is especially critical—the majority of emergency plumbing searches happen on phones.

What to Check

• Google Search Console setup: If you haven't claimed and verified your site in Search Console, do that before anything else. It's the most important free diagnostic tool available.
• Crawl errors: In Search Console, check the Coverage report for pages marked as errors or excluded. A high volume of 404s or redirect chains signals structural problems.
• Page speed and Core Web Vitals: Use Google's PageSpeed Insights (free) to test your homepage and your most important service pages. Pay attention to Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS). Sites that fail Core Web Vitals on mobile are at a disadvantage in competitive local markets.
• Mobile usability: Check Search Console's Mobile Usability report. Text too small to read, clickable elements too close together, or content wider than the screen are all fixable issues that affect user experience and rankings.
• HTTPS: Your site should be fully served over HTTPS. Mixed content warnings (some images or scripts loading over HTTP) can undermine trust signals.
• Duplicate content: Check whether your site is accessible at both www and non-www versions, or both HTTP and HTTPS—these create duplicate indexing issues if redirects aren't configured correctly.

Red Flag Threshold

If Search Console shows more than a handful of coverage errors, your LCP exceeds 4 seconds on mobile, or you have no Search Console data at all, address technical issues before moving to content or local layers. Building on a broken foundation wastes effort.

For plumbing businesses, local SEO is where most search visibility comes from. The Google Map Pack—those three business listings that appear above organic results for searches like "plumber near me"—drives a significant share of calls for service-area businesses. Listing accuracy directly affects whether you appear there.

Google Business Profile Audit Points

• Business name: Should match your legal or commonly known trade name exactly—no keyword stuffing (e.g., "Best Plumber Dallas | ABC Plumbing" is a violation).
• Primary category: Should be "Plumber." Secondary categories can include Drainage Service, Water Heater Installation Service, or others that match your actual services.
• Service area vs. storefront: Most plumbing businesses should be set as service-area businesses, not storefront locations, unless customers regularly visit your physical address.
• Phone number and website URL: These must match exactly what appears on your website and in major citation sources (Yelp, Angi, HomeAdvisor, BBB).
• Services section: GBP allows you to list individual services. Fill this out completely—it contributes to relevance signals for specific service searches.
• Photos: Active profiles with recent photos of real work, vehicles, and team members consistently outperform sparse profiles in competitive markets, based on our experience with service-area businesses.

Citation Consistency Check

NAP consistency—Name, Address, Phone number—across citation sources matters for local ranking. Use a free tool like BrightLocal's citation checker or Whitespark's lookup to scan for inconsistencies. Common issues include old phone numbers on directory listings after a number change, address variations (St. vs Street, Suite vs Ste), and duplicate listings created when a business moves.

If you find more than a few inconsistencies across major directories, a citation cleanup is worth prioritizing before building new links or content.

Most plumbing websites are built with a general "Services" page that lists everything from drain cleaning to water heater installation in a few bullet points. That structure doesn't rank for specific searches. Google needs individual pages with enough content to understand what service you offer, where you offer it, and who it's for.

Service Page Audit

Make a list of every service your business offers. Then check whether a dedicated page exists for each one. Common gaps in plumbing websites include:

• Emergency plumbing (high-intent, high-value — often missing a dedicated page)
• Water heater repair vs. water heater replacement (different searcher intent, should be separate pages)
• Sewer line services (inspection, repair, replacement — often lumped together)
• Commercial plumbing (if you serve commercial accounts, this needs its own section)
• Specific fixture services (faucet repair, toilet repair, garbage disposal)

Location Page Audit

If you serve multiple cities or neighborhoods, each major service area should have a page that combines a specific service with a specific location. A page targeting "water heater repair in [City Name]" performs better than a single citywide services page for that term.

Check your site's current location pages against your actual service area. Signs of a Missing service-and-location page combinations are a common [content gap](/resources/plumber/plumbing-seo-checklist) that suppresses local rankings: you serve a city but have no page targeting it, or your location pages are thin templates with only the city name swapped in and no unique content.

Content Quality Check

For each existing service page, ask:

• Does the page explain the service clearly, including common causes, what the repair involves, and what to expect?
• Is there a clear call to action—phone number, contact form, or booking link?
• Does the page include the city or service area naturally in the content, not just jammed into headings?
• Is the page at least 400-600 words, or is it a few sentences with a stock photo?

Thin pages rank poorly and create a weak impression for visitors who arrive from search. Both problems are fixable with targeted content expansion.

Your competitors' rankings tell you what Google considers authoritative in your specific market. Analyzing what the top-ranking plumbers in your area are doing gives you a concrete target rather than generic industry advice.

Identify Your Real Competitors

Search for your primary service terms in Google while in incognito mode, using a location that matches your target area. Note which businesses consistently appear in the Map Pack and in the top organic results. These are your actual competitors—not necessarily the largest plumbing companies in your city, but the ones Google currently trusts most for these searches.

What to Compare

• Page count and service coverage: How many service pages do top-ranking competitors have? Do they have location-specific pages? Use a site search (site:competitordomain.com) to get a rough count.
• GBP activity: Check their Google Business Profile. How many reviews do they have? How recent? Do they post updates regularly? A profile with 200+ reviews and recent activity signals ongoing engagement.
• Backlink profile basics: Free tools like Ubersuggest or the limited version of Ahrefs can show you which sites link to your competitors. Look for local news mentions, chamber of commerce listings, or industry directories you're missing.
• Content depth: Visit their top-ranking pages. Are they 300-word pages or detailed 800+ word pages with FAQs, process explanations, and local signals? Match or exceed that depth.

Using the Gap Analysis

The goal isn't to copy competitors—it's to identify where your site is visibly weaker and close those gaps strategically. In our experience working with service-area businesses, the most common gaps are review volume, missing city-specific pages, and GBP category mismatches. Address the easiest high-impact gaps first rather than trying to overhaul everything at once.

After working through all four layers, you'll have a list of issues across technical, local, content, and competitive dimensions. The challenge is prioritization—not every fix has equal impact, and some require specialist help.

Simple Prioritization Framework

Score each issue on two dimensions: impact on local search visibility (high/medium/low) and effort to fix (high/medium/low). Tackle high-impact, low-effort fixes first.

• Highest priority (fix this week): Search Console not set up, Google Business Profile unclaimed or incomplete, NAP inconsistencies on major directories, broken pages returning 404 errors, site not mobile-friendly
• High priority (fix this month): Missing service pages for core offerings, thin location pages, no reviews or review response activity, slow mobile page speed
• Medium priority (plan for next quarter): Competitor content gaps, secondary service pages, additional city pages, backlink outreach
• Requires specialist review: Manual penalty notices, sudden unexplained traffic drops, toxic backlink profiles, site architecture problems affecting crawl budget

When to Handle It Yourself vs. Hire Help

Content creation, GBP updates, citation cleanup, and basic on-page edits are tasks most business owners can handle with guidance. Technical issues involving site architecture, redirect logic, schema markup, or penalty recovery are areas where mistakes can compound existing problems—those are worth professional review.

If your audit surfaces more than a handful of issues across multiple layers, or if you've been running the site for over a year with little organic traction, the time cost of self-managing a full fix list often exceeds the cost of bringing in a specialist. Use what you've learned here to evaluate proposals from SEO professionals critically—you now know what a real audit covers.
