The problem
Two domains,
one business.
Two of the business’s own domains, foursolutions.sg and fourpestsolutions.sg, were competing for the same searches. From 3 to 23 July 2026, before Tendou’s work, foursolutions.sg recorded 88 Google clicks, 11,988 impressions and an average position of 30.75.
What changed
Dated work,
from the change log.
- 29 August 2026. The site moved to Cloudflare Pages and Google’s change of address from fourpestsolutions.sg to foursolutions.sg was filed.
- 23 September. All 195 WhatsApp links were given the page they came from, so enquiries can be traced to a page.
- 30 September. Fact and wording corrections across 41 pages, removing statements the business could not document.
- 8 to 10 October. New job guides, verbatim Google review quotes, and redirects that send the old non-secure and www addresses to the secure site. These postdate every figure below.
The record
Named for specific
jobs.
In a logged-out ChatGPT panel on 9 October 2026, 28 answers completed and 12 named Four Solutions; 11 of those 12 linked a specific foursolutions.sg page. It was named for mould, booklice, car fumigation, fly control, restaurant contracts and nest removal. It was not named for general pest control, bed bugs, termites, rodents, cockroaches, ants or mosquitoes.
On the same day, Google AI named it in 4 of 30 completed answers, Gemini in 2 of 32 and Perplexity in 1 of 9.
Equal 28-day windows for foursolutions.sg: 12 August to 8 September and 9 September to 6 October 2026. Clicks moved from 85 to 89 and impressions from 21,952 to 21,175. The old domain fell from 53 clicks to 1 over the same windows, so the two domains together went from 138 to 90 clicks. Year on year, July to September clicks were broadly flat.
An earlier result
Why the mould answer
is not our result.
A saved Google AI answer for “best mould removal in singapore” listed Four Solutions first. Its sources included a third-party list dated 6 February 2024 that also put Four Solutions first, and the file existed by 30 July 2026, close to the start of Tendou’s work. It reflects the business’s existing reputation, not Tendou’s changes.
Later checks of closely related questions did not name the business: Google AI on 25 September 2026 for “mould removal singapore”, and Google AI, ChatGPT, Gemini and Perplexity on 9 October 2026 for “best mould removal company singapore”.
