Most local service businesses have never had a real SEO audit. Not because they don’t want one, but because the tools that do it properly usually sit behind a $99/month subscription or a 40-minute sales call disguised as a “free consultation.”
So we built seven free tools that answer the questions we get asked most by HVAC companies, law firms, healthcare practices, and other local businesses: is my site technically sound, is my schema markup correct, would my Google listing pass an actual audit, and what would fixing any of this actually be worth in revenue. No email gate to see your score, no sales call required to use them.
Here’s what each one does, who it’s built for, and how to use them together for a 10-minute audit of your own marketing.
1. Website Audit Tool: is your site technically sound?
Paste in your URL and this tool scores your site across four areas: technical SEO (page speed signals, mobile-friendliness, crawlability), on-page content (titles, headings, keyword usage), structured data (whether schema markup is present and valid), and local SEO signals (NAP consistency, location pages). You get a single score plus a breakdown of exactly what’s dragging it down.
Best for: getting a baseline before you spend money on an SEO campaign, or checking whether a new page you just published actually shipped clean.

2. Schema Markup Generator: structured data without touching code
Schema markup (the structured data that tells Google — and increasingly, AI answer engines — exactly what your business is, where it’s located, and what questions it answers) is one of the highest-leverage, least-used tactics in local SEO. Most business owners have never added it because it means writing JSON-LD by hand.
This tool fixes that: fill in your business details and it generates ready-to-paste LocalBusiness and FAQ structured data. No developer required.
Best for: any local business that doesn’t already have LocalBusiness schema on their homepage — which, in our experience auditing client sites, is most of them.

3. Marketing ROI Calculator: what would fixing this actually be worth?
SEO and marketing conversations tend to stay abstract — more traffic, better rankings, more visibility. This calculator forces the conversation back to revenue: enter your current lead volume, close rate, and average customer value, and see what a realistic improvement in either close rate or lead volume is worth in dollars, with the math shown transparently instead of buried in a proposal.
Best for: deciding whether a marketing investment is worth making before you make it, or justifying a budget internally.

4. SERP Snippet Preview Tool: what will people actually see in Google?
Titles and meta descriptions get cut off in search results more often than most people realize, and the cutoff point isn’t a fixed character count — it’s pixel width, which varies by letter. This tool renders a pixel-accurate preview of exactly how your title and description will appear in Google’s results, with truncation warnings before you publish, not after.
Best for: checking any page before it goes live, especially long service-page titles that are easy to write too long without realizing it.

5. Missed-Call Revenue Calculator: what are unanswered calls actually costing you?
Built specifically for HVAC, plumbing, electrical, and other home service businesses, where a missed call is rarely a lost inquiry — it’s a lost job that went to whichever competitor picked up next. Enter your average job value and estimated missed-call volume, and this tool estimates the revenue walking out the door every month.
Best for: home service businesses deciding whether to invest in call tracking, an answering service, or missed-call text-back automation.

6. Content Readability Grader: will people (and Google) actually read this?
Paste in any page of text and get a Flesch-Kincaid readability score, an estimated grade level, and flags for the overly long or passive sentences that make content harder to scan. This matters for two audiences at once: the human reading your service page on a phone screen, and the algorithms — both Google’s and the AI answer engines — that favor clear, direct writing when deciding what to surface as an answer.
Best for: checking a blog post or service page draft before you publish it, especially anything written to sound “professional” that might actually just sound dense.

7. Google Business Profile Health Check: is your listing actually optimized?
For any business that depends on local, “near me” search — which is nearly every industry we work with — the Google Business Profile matters as much as the website, sometimes more. Answer 12 quick questions about your profile (categories, photos, posting frequency, review response rate, and more) and get a scored breakdown of exactly what to fix first.
Best for: any business that hasn’t touched their Google Business Profile since they first set it up.

How to use these together: a 10-minute audit
Individually, each tool answers one question. Run in sequence, they give you a genuinely useful snapshot of where you stand:
- Start with the Website Audit Tool to get your baseline score and see the biggest issues at a glance.
- Run the Google Business Profile Health Check next, since for most local businesses this drives more calls than the website itself.
- Check your homepage and top service page in the SERP Snippet Preview Tool to see if your titles are getting cut off or failing to stand out.
- Paste your service page copy into the Content Readability Grader to see if it reads like a human wrote it for a customer, or like a lawyer wrote it for a compliance department.
- If the audit turned up missing schema, use the Schema Markup Generator to fix it in the same sitting.
- Finish with the Marketing ROI Calculator to put a number on what closing these gaps could be worth, so you can decide what’s actually worth prioritizing.

Frequently asked questions
Are these tools actually free, or is there a catch?
They’re free to use, with no email required to see your results. We built them because they’re genuinely useful on their own, and because some of the people who use them decide they’d rather have us handle the fixes than do it themselves — but there’s no gate on the tools.
Which tool should I start with if I only have five minutes?
The Website Audit Tool. It’s the fastest way to see your overall standing across technical SEO, content, schema, and local signals in one score.
Do I need any technical or coding knowledge to use these?
No. Every tool is built for business owners and marketers, not developers. The Schema Markup Generator, for example, outputs ready-to-paste code, but you don’t need to understand the code to use it.
How is the Missed-Call Revenue Calculator different from a general ROI calculator?
It’s purpose-built for home service businesses where missed calls translate almost directly into lost jobs. It uses your average job value and call volume specifically, rather than generic marketing inputs.
Why does schema markup matter for AI search, not just Google?
Structured data doesn’t just help traditional search rankings. AI answer engines like ChatGPT, Perplexity, and Google’s AI Overviews rely heavily on clearly structured, well-labeled data to understand what a business does and to decide what to cite when answering a user’s question.
How often should I re-run these audits?
Quarterly is a reasonable default for most businesses, or any time you make a significant change to your website, launch a new service page, or update your Google Business Profile.
