The problem

Challenges before the campaign

Limited organic visibility in regional search engines (e.g., Google SG).
A weak backlink profile from travel or transport blogs.
A language and local-SEO gap.
Low Domain Authority and Domain Rating.

The approach

SEO goals & strategies

The programme balanced technical hygiene with authority building and content depth:

Hygiene first, titles, descriptions, keyword placement and on-page fundamentals.
Backlink acquisition, guest posting on travel and news portals, region-specific profile links and directory submissions, targeting competitor domains, sponsored mentions in travel magazines, and digital PR.
Content structure, keyword-gap analysis to target terms sitting in lower positions, LLM-friendly content, and diversified, data-rich content.

Referring domains spiked in June and were deliberately disavowed to keep spam link generation under control and growth natural.

Before vs after, March 2024 to October 2025

Key SEO metrics, before vs after

Organic sessions rose around 100% since early March 2024, with the mid-year surge aligning to content-refresh and long-tail targeting.

The outcome

Results

Organic sessions increased by around 100% since early March 2024.
Top-3 and top-10 keyword counts grew strongly, total top-10 keywords almost doubled, showing stronger visibility for competitive terms.
Rankings held steady over time, indicating durable, well-maintained visibility rather than short-lived spikes.

Reporting was revised after 15 September 2025 following Google’s removal of the &num=100 parameter, which changed how positions are recorded.
