How to build your first Directory Site With AI (No Coding Required)

The first directory site took about a week to build. No coding background, no web development experience. Just a spreadsheet full of business data, an AI assistant, and a Hostinger account that costs less than a coffee per day to run.

That site is murwillumbahdirectory.com. It indexes local businesses across my town and exists as a proof of concept for what these tools can do. This article walks through exactly how it works, what it costs, and how anyone can do the same thing in almost any niche.

What a Directory Site Actually Is

A directory site is an organised list of businesses, places, or services in a specific niche or location. Yelp is a directory. Yellow Pages is a directory. The interesting opportunity right now is that niche directories built for specific topics or regions easily rank on Google and provide some helpful info to users.

A directory for Food Trucks in Australia. Plumbers in New Zealand. Dog groomers in a specific city. These are real searches with real monthly traffic and almost no competition in the results. The business model is simple: build the directory, get it indexed by Google, and earn through affiliate links, lead generation, paid featured listings, or advertising. This won't happen overnight, but the cost to build and run one of these sites is low enough that the barrier to try is almost nothing.

Finding Your Niche

The best niches for a first directory are ones where there are lots of entries (hundreds or thousands of businesses), the searches are specific enough that big platforms do not dominate the results, and you have some genuine interest or knowledge in the area.

Start by looking at categories Google Maps covers well but dedicated directories cover poorly. Trade services in regional areas, specialty retail categories, accommodation types, professional services in smaller cities. If you search for something and find no dedicated directory in the first page of results, that is a gap worth exploring.

The Domain — More Important Than Most People Think

New domains start from zero trust with Google. It can take months for a brand new domain to get properly indexed. An expired domain is one that someone previously registered, used, and let lapse. It already has some history with Google, sometimes backlinks from other sites, and a meaningful head start on indexing.

expireddomains.net is the main tool for finding these. You search for keywords related to your niche, filter by domain extension (.com.au, .com), check the domain authority score and how many sites were linking to it, and look for something that fits your niche well. A solid expired domain in the right category can be the difference between sitting at 5% indexed for six months and reaching 70% in six weeks.

Expired domains that have just lapsed typically cost $10 to $30 to register. Some with strong backlink profiles get auctioned for more. For a starting directory, budget around $15 to $25 and look for one with at least a few referring domains in your niche area.

Getting the Data — Outscraper

A directory needs data. The best source for local business information is Google Maps, and Outscraper is a tool that legally scrapes Google Maps listings into a clean spreadsheet. You search for a business category in a location, set it running, and it returns every business in that search with name, address, phone, website, category, rating, review count, and more.

For a small directory covering a few hundred businesses in a regional area, a run on Outscraper costs roughly $5 to $15 depending on how many records you pull. For something national with thousands of entries, budget more. The output is a CSV file that becomes the raw material for the entire site.

Turning the Data Into a Website

This is where it gets interesting. There are several ways to take a spreadsheet of business data and turn it into a live website, and the right one depends on how much functionality you need.

Static HTML is the simplest approach and the one used for the first few directory sites built here. You give the CSV to an AI, ask it to write code that generates an individual HTML page for each listing, and upload the result to Hostinger. No database, no backend, no ongoing complexity. Pages load fast, Google indexes them well, and the whole thing costs almost nothing to run. The trade-off is that updating data or adding features requires going back through the same process each time.

WordPress is a step up in flexibility. Dedicated directory plugins like GeoDirectory handle listing pages, search, category filtering, and even user-submitted listings. WordPress on Hostinger is a common and reliable combination for directories that need a bit more functionality. Plugin costs add up but the extra capability is usually worth it.

Webflow and other drag-and-drop builders can work for very small directories but struggle with bulk data import. They are better suited to sites with under 50 listings being entered manually, not hundreds from a spreadsheet.

For a next level is a proper database-driven web application, you can use Next.js with a Convex backend and supports real user accounts, social features, photo uploads, reviews, and real-time data. This is significantly more complex and is really a web app rather than a directory. It is not the starting point for a first project but it shows the direction things can grow once the basics are established.

How to Actually Use AI to Build This

This is the part most people underestimate going in. You do not need to know how to write code. You do need to learn how to describe problems clearly and get comfortable iterating on the results.

The basic workflow: you have a spreadsheet from Outscraper. You open Claude or ChatGPT. You describe what you want. Something like "I have a CSV file with columns for business name, address, suburb, state, phone, website, and category. Write me Python code that reads this CSV and generates one HTML page per business, plus an index page listing all of them." The AI writes the code. You run it. Something probably goes wrong. You paste the error back in and ask it to fix it. It does. You run it again. You keep going until you have something working.

The skill is not coding. The skill is describing what you want clearly, recognising when something is off, and knowing how to ask the right follow-up question. Anyone can learn this. It takes patience on the first project and gets faster every time after that.

Claude tends to handle longer and more complex tasks better, and is good for reasoning through problems that have multiple moving parts. ChatGPT is solid for quick generation tasks. Both are useful and most people who build things this way end up switching between them depending on what they are doing. Both cost around $20 a month for the paid version, which is worth it if you are building anything seriously.

Realistic Expectations

A directory site is a slow burn. Google does not rush to index hundreds of pages from a relatively new domain. Even with an expired domain, expect the first couple of months to be quiet from a traffic perspective. The sites that do well are the ones where each listing page has decent content (not just a name and address, but hours, a description, category context), the domain has some backlink history, and a few external links exist pointing at the site.

Income from a small regional directory can range from nothing to a few hundred dollars a month through affiliate links or paid featured listings once it gets established. Larger national niche directories with good SEO can earn significantly more. Treat the first one as a learning exercise and proof of concept. The knowledge transfers directly to every site built after it.

What It All Costs

The basic entry point for a static HTML directory on Hostinger is low. An expired domain costs $15 to $25, Hostinger hosting runs $3 to $13 per month and covers multiple sites, a data pull from Outscraper for a few hundred listings is $5 to $15, and an AI tool subscription is around $20 per month. Total to get a first site live: roughly $50 to $80 all in, then $25 to $35 per month ongoing.

WordPress adds one-off plugin costs, typically $50 to $200 for a quality directory plugin, plus the same hosting and domain costs.

The full web app setup (Next.js, Convex, Vercel) has almost no additional monetary cost on top of what you are already paying. Vercel and Convex both have generous free tiers. The cost is time, not money.

The Workflow From Start to Live Site

Where to Start

Pick a niche. Find an expired domain that fits it on expireddomains.net. Pull the data from Outscraper. Open Claude and start describing what you want the pages to look like. The first hour will feel uncertain. By the third hour you will have something that looks like a website. By the end of the first week you will have something live.

murwillumbahdirectory.com exists as proof that this works and was built exactly this way. The tools are available to anyone and the cost to start is genuinely low. The hardest part is picking a niche and starting.
