Case Study: Designing a Map-Based Marketplace Web App in Chonburi, from a Subscription-Bound AI Prototype to an Owner-Controlled System

The owner built a map-based marketplace with an AI website builder, then ran into its limits and monthly fees and wanted to move to their own system. They did not know how many pages the site had or how its data was stored, so the first job was to map the existing system clearly.

Case Study: A 3-Language Hua Hin Private Transfer Website, 400+ Pages, 3 Booking Types and First Google Clicks Within Days

A private transfer service in Hua Hin already had a website, but its customers search by route, such as Bangkok airport to Hua Hin, and want a clear price before they book. The owner wanted a new site covering every route people actually search for, in several languages, taking one-way, return and day-tour bookings.

Case Study: A Bangkok Property Agency With 2,300 Listings, Yet Google Indexed Less Than Half. The Audit Traced It to the URL Structure

The site had more than 2,300 real rental and sale listings, yet Search Console showed 8.06K pages not indexed and clicks had been flat for 15 months. The owner had built and run everything himself. He watched "Crawled – currently not indexed" keep climbing without knowing the cause, and wanted the listing pages to earn traffic of their own.

Case Study: Keyword research before building a site for a new deep-tech company with 3 business lines, whose brand domain was listed for sale

A technology company less than 3 months old runs 3 business lines that sell to completely different buyers, and has no website at all. Its brand name on .com is listed for sale on a domain marketplace, the .net is already registered by someone else, and the company still has no email address on its own domain.

13,660Searches per month across both markets

Case Study: Keyword research before building the site — an island boat tour company with 13,660 searches a month, no website, and two brand domains sitting unregistered

This boat tour company owns its boats, sells real routes and holds a 4.8-star review score — yet it has no live website, and both of its brand domains are registered to nobody at all. Today every booking comes through agents and booking platforms, many of which already resell this operator's own trips.

Case Study: SEO Audit of an Outbound Tour Company, a 13-Year-Old Domain and Thousands of Tours Google Could Not Read

An outbound tour company had a 13-year-old domain and 3,400+ tours, yet "ทัวร์ญี่ปุ่น" (Japan tour), searched 9,900 times a month, was not even in the Top 100. It already had country pages with content and FAQs. The cause: country pages delivered their content through JavaScript only, and all 161 blog articles told Google they were the same page.

Case Study: Keyword research before building a site for an air conditioner wholesaler: a small market, weak competitors, and how much to expect from SEO

An air conditioner wholesaler selling to contractors wanted to know, before building its website, whether SEO was worth it. It has no showroom and shows no prices, and the term "แอร์ราคาส่ง" (wholesale-price air conditioners) gets only about 130 searches a month combined. The company also has 2 side businesses with much bigger search terms, but most of the people searching them are not wholesale customers.

Case Study: SEO audit for a townhome and villa developer whose domain was already in the deletion queue on audit day

A townhome and villa developer had a well-designed bilingual website, but on the day we audited it the domain had been expired for over 2 months, was in pending delete status, and the site would not load. Even before the site went down, it ranked for no keywords at all, because its SEO basics had been left unfinished since the site was built.

A software house built its site in Next.js and scored a perfect 100 on Lighthouse SEO, with 17 real projects to show, yet it did not rank for a single keyword in Thailand, because the whole site pushed a term searched only about 10 times a month. 97.6% of its inbound links were spam, and an automated chat covered about 40% of the mobile screen within the first 3 seconds.
