A first directory site can take about a week to build with no coding background and no web development experience. Just a spreadsheet of business data, an AI assistant, and hosting that costs less than a coffee a day. Here is exactly how it works, what it costs, and how to do the same in almost any niche.
What a directory site actually is
A directory is an organised list of businesses, places, or services in a specific niche or location. Yelp is a directory. The Yellow Pages is a directory. The interesting opportunity right now is that small, focused directories can rank on Google for searches that bigger sites do not bother optimising for.
Antique stores in a region. Plumbers in regional Victoria. Dog groomers in a specific suburb. These are real searches with real monthly traffic and almost no competition. The model is simple: build the directory, get it indexed, and earn through affiliate links, lead generation, paid featured listings, or advertising. None of that happens overnight, but the cost to build and run one is low enough that trying it costs almost nothing.
Finding your niche
The best first niches have lots of entries (hundreds or thousands of businesses), searches specific enough that big platforms do not dominate, and a topic you genuinely find interesting. Look for categories Google Maps covers well but dedicated directories cover poorly: trade services in regional areas, specialty retail, accommodation types, professional services in smaller cities.
If you search for something and there is no dedicated directory on the first page of results, that is a gap worth exploring. One of the first directories I built came from a simple observation: a regional area full of small businesses with almost no online presence. A local directory made sense as a starting point and a test case.
The domain, more important than most people think
New domains start from zero trust with Google, and it can take months for a brand new domain to get properly indexed. An expired domain is one someone previously registered, used, and let lapse. It already has history with Google, sometimes backlinks, and a real head start on indexing.
expireddomains.net is the main tool for finding these. Search keywords related to your niche, filter by extension, check the authority score and how many sites link to it, and look for one that fits. A solid expired domain can be the difference between sitting at 5 percent indexed for six months and reaching 70 percent in six weeks. Recently lapsed ones usually cost $15 to $25 to register.
Getting the data
A directory needs data, and the best source for local business information is Google Maps. Outscraper is a tool that legally pulls Google Maps listings into a clean spreadsheet: name, address, phone, website, category, rating, review count, and more. For a few hundred businesses in a region, a run costs roughly $5 to $15. The output is a CSV that becomes the raw material for the whole site.
Turning the data into a website
There are several ways to take a spreadsheet and turn it into a live site. The right one depends on how much functionality you need.
Four ways to build
| Approach | Best for | Trade-off |
|---|---|---|
| Static HTML | Fast, cheap, ranks well; AI writes code that makes one page per listing | Updating data means re-running the process |
| WordPress + plugin | Search, filtering, user submissions (e.g. GeoDirectory) | Plugin costs and more upkeep |
| Drag-and-drop builder | Tiny directories under ~50 manual listings | Struggles with bulk data import |
| Database web app | Accounts, reviews, photos, real-time data (Next.js + a backend) | Much more complex; really a web app |
How to actually use AI to build this
This is the part most people underestimate. You do not need to know how to code. You do need to learn how to describe problems clearly and get comfortable iterating.
The basic loop: you have a spreadsheet. You open an AI assistant and describe what you want, for example, "I have a CSV with business name, address, suburb, state, phone, website and category. Write Python that reads it and generates one HTML page per business, plus an index page." The AI writes the code. You run it. Something breaks. You paste the error back and ask it to fix it. You repeat until it works.
The skill is not coding. It is describing what you want clearly and asking the right next question.
Claude tends to handle longer, more complex tasks well; ChatGPT is great for quick generation. Both cost around $20 a month for the paid tier, and most people switch between them depending on the job.
Realistic expectations
A directory is a slow burn. Google does not rush to index hundreds of pages from a newish domain. Even with an expired domain, expect the first couple of months to be quiet. The sites that do well have decent content on each listing page (hours, a description, category context), a domain with some backlink history, and a few external links pointing in. Income can range from nothing to a few hundred dollars a month once established, and far more for larger national niches. Treat the first one as a learning exercise; the knowledge transfers to every site after it.

Where to start
Pick a niche. Find an expired domain that fits it. Pull the data. Open an AI assistant and start describing what you want the pages to look like. The first hour feels uncertain. By the third hour you have something that looks like a website. By the end of the first week you have something live. The hardest part is picking a niche and starting.
