HomeGuide is the easiest win on this list.

A client of ours ran the numbers on his own name last spring. He asked ChatGPT what a water heater replacement costs in his metro, expecting to see his company somewhere in the answer. He didn't. He saw a price range, a note about permits, and a site called HomeGuide he'd never once thought about in eleven years of running plumbing trucks. He'd spent about $60,000 on marketing that year. The site that got quoted had cost him nothing, because he wasn't on it.

The short answer: Creating a HomeGuide pro profile is free — no membership fee, no subscription, no annual contract — and takes about twenty minutes at homeguide.com/pro; the highest-leverage part is filling in real price ranges for your common jobs, because HomeGuide's cost guides are what AI actually quotes.

The smallest number on the list, and we're going to say so

HomeGuide sits ninth in our citation study. Across roughly 14,000 AI searches about plumbing, we logged 9,293 citations to third-party sources. HomeGuide accounted for 559 of them — 290 in ChatGPT, 249 in Perplexity, 20 in Google AI Overviews. That's six percent of the total. It is the smallest slice of the ten sites we tracked, and we're not going to dress it up as anything bigger.

Here's why it's still first on the to-do list: it's the only one of the ten with genuinely nothing attached. No annual membership like the Angi-adjacent world. No monthly subscription. No sales rep calling you in March about your renewal. HomeGuide's own pro page says it directly — your profile is free, no membership fees, no subscription fees, no annual fees. Their business pricing page repeats it: no monthly fee, unlimited usage.

So the math on this one is unusual. Small upside, but the downside is a Friday afternoon. Every other post in our series on the websites AI reads before recommending a plumber involves a real cost-benefit argument. This one doesn't. You just do it.

For the record: HomeGuide is operated by Liaison, Inc. Their help documentation now redirects to a platform called Talo, which suggests the software side of the business has been rebranded, though the consumer-facing marketplace is still HomeGuide. Nothing about that changes what you should do with the profile.

Why HomeGuide punches above its weight

HomeGuide is two businesses wearing one domain. There's a marketplace where homeowners request quotes from local pros — that part is unremarkable, and it looks and behaves the way you'd expect. Then there's the cost guide library, which is where all the AI citations actually come from.

They have hundreds of these. "How much does water heater installation cost." "Drain cleaning cost." "Average plumbing estimates." "Cost to snake a drain." Each one opens with a number in the first line — water heater installation leads with $600 to $3,100 for a standard tank replacement and $1,400 to $5,600 for tankless. Drain cleaning leads with $100 to $800, then breaks it down: basic fixture cleaning $100 to $275, hydro jetting a severe main $300 to $800.

That structure is the entire reason a language model quotes it. An AI answering "what does drain cleaning cost near me" needs a defensible number with a source attached. HomeGuide hands it one in the first fifty words, in a table, with conditions. Your services page, meanwhile, probably says "we offer fast, affordable drain cleaning with upfront pricing" — which contains no fact a machine can extract and no number it can repeat.

And here's the part most plumbers miss. HomeGuide states its methodology plainly: it tracks millions of estimates homeowners get from contractors and publishes those prices. The prices in those cost guides come from pros. From estimates. From profiles. You are not just listing on a directory — you're feeding the dataset that the directory publishes and AI cites.

Concrete numbers get quoted. Vague profiles get ignored.

Go look at HomeGuide's plumber listings for any decent-sized city. A lot of the profiles show the same three words where a price should be: Contact for price.

That's a dead end. Not because homeowners hate it — plenty of people click anyway — but because it's an empty cell in a database. When an AI assembles an answer about plumbing costs in Dallas, "contact for price" contributes exactly nothing. It cannot be quoted, compared, ranged, or averaged. The profile might as well not exist for that purpose.

A profile that says "drain cleaning, $145 to $325 depending on access and line length, camera inspection included on main line jobs" is a completely different object. It contains three extractable facts: a service, a range, and a condition. That is the shape of a thing that gets repeated.

This is the same principle we hammer on for plumbing company websites and it applies everywhere in the AI era. Specificity is citability. "Affordable" is not a fact. "$145 to $325" is a fact. Machines quote facts.

The objection is always the same and it's fair: I don't want to publish prices, my competitors will see them. Two things. First, your competitors already know what you charge — they've seen your invoices in customers' kitchens for years. Second, HomeGuide is publishing price ranges for your trade in your market whether you participate or not. The only question is whether the numbers being published reflect the kind of work you do, or the kind of work the cheapest guy in town does.

What to have ready before you sit down

Pull your last twenty invoices and work out honest ranges. To get you moving, here are HomeGuide's own published national ranges for common residential jobs. These are illustrative — national figures from HomeGuide's cost guides, not a pricing recommendation. Your market, your truck cost, and your warranty are your business. Use your numbers.

If your numbers land well above these ranges, say so and say why in the description field — permit handling, same-day service, ten-year warranty, licensed journeyman on every truck. A high price with a stated reason is more quotable than a low price with no context.

The twenty-minute setup

1. Go to homeguide.com/pro and start the signup form. It opens by asking what service you provide. Pick plumbing.
2. Set your service area properly. Not "the whole metro" — the cities and ZIPs you'll actually drive to at 7am. Overreach here produces junk you'll ignore.
3. Select every service category you genuinely do. Water heaters, drain cleaning, repiping, sewer, gas lines, fixture install, leak detection, water treatment. Each one is a separate door.
4. Fill in every pricing and estimate field. This is the step. If you skip it you've done a fifteen-minute version of this task and gotten most of the value.
5. Write the business description like a person. Years in business, license number, service area, what you specialize in, one thing that's true about you and not true about the guy down the road.
6. Upload eight to twelve real photos. Trucks, techs in uniform, finished water heater installs, a clean job site. Not stock photos of a wrench.
7. Ask five recent happy customers for a HomeGuide review. Profiles display review counts and hire counts on the listing card — a profile with zero of both reads as unproven.
8. Set a calendar reminder for six months out to update your prices. That's the maintenance burden. That's all of it.

Then leave the advertising side alone until you've decided you want it. HomeGuide doesn't publish lead prices anywhere we could find — the pro page says you only pay for the leads you want and can pause or stop at any time, but there's no rate card. Paid leads are a separate decision with a separate budget conversation, and it belongs next to your other paid channels, not tacked onto a free profile. If you're weighing where lead spend should actually go, we've written about how plumbing marketing budgets should be split.

Sizing this honestly

Six percent of citations. Ninth of ten. Twenty minutes and no money. That's the whole pitch, and if it sounds modest, it is.

What it isn't is a strategy. A HomeGuide profile will not fix a business whose phone isn't ringing. It won't outrank anybody. It sits alongside a real plumbing SEO program and paid channels that produce actual booked jobs, and its job is to be one more place where a machine finds a concrete, accurate fact about your company and repeats it. Do enough of those and the pattern starts to hold across every AI answer in your market.

We spend most of our time telling plumbing company owners which things aren't worth their money. This is the rare one that costs nothing, so we'll say the opposite: do it this week. If you'd rather talk about the seventy percent of your marketing that does cost money and you're not sure is working — that's the conversation we're actually built for. Book a call and we'll start by telling you the truth about what's working and what isn't.
