Client name withheld under NDA.
Waterproofing is a trade where the owner and the customer use completely different words. Contractors talk about torch-on membranes, PU injection and cementitious coatings. Homeowners talk about a brown stain on the ceiling, a toilet that leaks into the flat below, or a wall that turns damp every time it rains. Searches for waterproofing singapore and waterproofing contractor singapore are competitive, and most of the people with an actual leak never type either phrase. They search for the symptom, often late at night and often while worrying about who will pay for it.
This contractor had built a good business on referrals and repeat work from property managers. Its website had 9 pages, and every one of them was named after a method: membrane waterproofing, PU injection, roof coating, and so on. Google showed the site for 6 keywords on page 1, almost all of them variations of the company's own service names. The site drew about 640 organic visitors a month and produced around 7 enquiries. The owner asked us a simple question: what are people actually searching for when they need us, and which pages should we build to be there?
We started with the client's own records, not a keyword tool. The office manager exported six months of WhatsApp messages and web form enquiries, 212 in all, and we noted the exact words people used to describe their problem. Then we pulled search data from SEMrush, Google Search Console, autocomplete and the People Also Ask boxes. That gave us 1,140 phrases, which we filtered down to 386 that described a real waterproofing or leak problem in Singapore homes and buildings.
Starting with real messages kept the research honest. Keyword tools show volume, not how a worried homeowner describes a leak. Almost nobody asked for waterproofing by name.
We sorted the 386 keywords into four intent groups. Problem searches, like a ceiling leaking after rain, made up 171. Responsibility searches, about who pays when a leak comes from the flat above, made up 64. Method searches, which used the contractor's own terms, made up 92. Hiring searches, like roof leak repair singapore or a contractor near a specific estate, made up 59. Three things surprised the owner. The word seepage, which nobody in the company used, appeared in 41 of the mapped keywords. The responsibility group had no page anywhere on the site. And PU injection, the service with the best margin, had almost no searches by that name, while searches about a cracked wall leaking in heavy rain described exactly the job it fixes.
Intent matters more than volume here. A person searching for who pays for a ceiling leak in an HDB flat is close to calling someone, even though the phrase looks like a question. Grouping by intent showed the client which searches were worth a page and which were only worth a line in an answer.
We turned the groups into a keyword mapping sheet with one row per page. Each page got one primary keyword, three to eight supporting keywords, the intent it served and the question it had to answer in its first paragraph. Five of the existing method pages were kept but re-pointed at the problem a customer would search for, so the PU injection page became the page for walls that leak when it rains. Fourteen new pages were planned. Keywords that overlapped were assigned to a single page so the site would not compete with itself.
A keyword list on its own does not change anything. The map is what tells a writer what each page is for and stops two pages chasing the same search. It also gave the owner a way to say no to page ideas that had no searches behind them.
We wrote and published the 14 new pages over eight weeks: eight problem pages (ceiling leaks, toilet leaks into the unit below, wall seepage, window leaks, flat roof ponding, planter box leaks, balcony leaks and landed house roof leaks), three responsibility guides for HDB flats, condos and landed homes, and three hiring pages, including one for ceiling leak repair singapore. Each page opened with what the customer was seeing, explained the likely cause in plain words, then showed the repair method and photos from the client's own jobs. We also tightened the on-page SEO on the five re-pointed pages.
The responsibility guides did something the client did not expect. They brought in condo residents and property managers who had not decided whether to call anyone yet, and the guides gave them a clear next step. Several of those readers became the larger, multi-unit jobs the contractor wanted.
We tracked all 386 keywords by page every week and checked which ones Google was matching to the wrong page. Eleven keywords were moved to a better page and the internal links were adjusted to match. Search Console also showed 23 new phrases the map had missed, mostly about leaks after renovation work, and we added them to existing pages.
A keyword map goes out of date the day it is finished. Checking it against real search data each month is what kept the new pages climbing instead of stalling at page two.
By Month 6 the site had 23 pages built around a keyword group, up from 9, and 58 keywords on Google page 1 instead of 6. Organic visitors grew from 640 to 1,710 a month, and 58% of them now landed on one of the leak problem pages, which did not exist at the start. Monthly organic enquiries rose from 7 to 23. The owner noted that enquiries from the problem pages usually arrived with photos of the leak attached, which made quoting faster.
Month 0 is the month before the engagement. Rankings from SEMrush position tracking, visitors and landing pages from Google Analytics, enquiries from the client's form and WhatsApp log.
212 customer messages read, 1,140 phrases collected, 386 mapped to pages in 4 intent groups.
14 new pages published and 5 existing pages re-pointed. Enquiries reached 12 a month by Month 4.
11 keywords moved to better pages, 23 new phrases added. Enquiries reached 23 a month.
If you run a trade or service business in Singapore, your WhatsApp and email history is the best keyword source you own. It shows how customers describe the problem in their own words, and those words are usually the searches you are missing.
Customers do not search for the technique you use. They search for what is going wrong. A page called PU injection reaches other contractors. A page about a wall that leaks in heavy rain reaches the person who needs PU injection.
Questions about responsibility look like research, but they come from people with a live problem. Answering them clearly, with the next step at the end of the page, brought in some of the client's best jobs.
