Targeted technical SEO reduced ASUS’s crawl waste and increased valid indexed pages through better crawl control and site signals.
SEO
ASUS was generating enormous crawl waste because Google was spending its time on low-value URLs instead of prioritising pages that mattered. Through a targeted technical SEO program focused on crawl control, smarter internal linking, and richer structured data, we reshaped how Google discovered and evaluated the site. The outcome was a much cleaner crawl footprint, far fewer low-quality pages competing for attention, and a strong uplift in valid indexed URLs, putting ASUS’s most important content in front of searchers more reliably.
The Challenge.
Google was crawling close to 1 million ASUS pages, yet only 7% (~56,000) were being indexed. This gap pointed to a major crawl-budget inefficiency: search engines were repeatedly hitting parameter and low-quality URLs, while higher-value pages were being deprioritised or missed. Left unresolved, this meant slower discovery of new content, weaker index coverage across key categories, and a ceiling on organic growth because the right pages weren’t consistently making it into Google’s index.
The Integrated Solution.
We implemented a multi-layered technical SEO solution designed to improve crawl quality and indexability end-to-end:
Parameter crawl management: We fixed the way Google accessed and interpreted parameter pages, reducing exposure to duplicative and low-value URL variants.
Internal linking improvements: We strengthened internal pathways to priority pages so Google’s crawler was guided toward content that deserved indexing.
Structured data enhancements: We improved structural/structured data to clarify site hierarchy and page purpose, helping Google better evaluate page quality and relevance.
Together, these changes redirected crawl activity away from waste and toward ASUS’s most important URLs.
The Results.
Reduced crawl waste by fixing parameter-page crawling.
Not-indexed pages down 87% (764k → 98k).
Indexed pages up 44% (59k → 85k).
The impact was immediate and measurable. Once parameter crawling and supporting signals were corrected, Google spent dramatically less time on low-quality pages. The number of not-indexed pages fell by 87% (764,000 → 98,000), showing a major decline in crawl waste. As crawl efficiency improved, valid index coverage expanded: indexed pages increased by 44% (59,000 → 85,000). Overall, ASUS shifted from a crawl-budget bottleneck to a healthier, more indexable site where Google consistently lands on and indexes the pages that matter most.
More brands that we’ve helped.
