Understanding Google’s Change: Why Removing ‘num=100’ Is a Positive Development for SEO Professionals
In recent updates, Google hasdecided to remove the ‘num=100’ parameter from its search URL, a move that has sparked discussions across the SEO community. Contrary to some assumptions, this change isn’t driven by concerns over automated bots scraping search results for content creation purposes. Instead, it signals a broader strategic shift related to how AI-powered tools interact with search data and Google’s ongoing efforts to maintain its dominance.
The Real Reason Behind the Removal
The elimination of the ‘num=100’ parameter appears to be a response to the increasing prevalence of AI models such as ChatGPT, Perplexity, and Claude. These tools utilize APIs like SerpAPI and other scraping mechanisms to pull extensive search results—sometimes up to 100 results—to generate more comprehensive and relevant answers for users. ChatGPT, in particular, has demonstrated a remarkable ability to analyze the top search results and synthesize information, often providing users with high-quality, direct responses that bypass traditional search engine interactions.
Google’s concern was that these AI applications could sideline its core business model—particularly advertising—by delivering answers that zero in on user intent without the need to click through to ads or external websites. To combat this, Google has restricted the amount of search result data accessible to such AI tools, notably limiting their access to only the top 10 results.
Implications for SEO Strategy
This adjustment has significant implications for Search Engine Optimization:
-
Focus on the First Page: With AI tools now primarily relying on the top 10 results, ensuring your content ranks within Google’s first page becomes even more critical.
-
Content Quality & Relevance: High-quality, authoritative content that resonates with user intent will continue to be paramount, as AI models will prioritize reputable sources within the top search results.
-
Traditional SEO Remains Vital: Despite the growth of AI-driven search interactions, classic SEO tactics—such as keyword optimization, website authority building, and user experience—maintain their importance for ranking on Google and influencing AI-generated responses.
Looking Ahead
In practical terms, SEO professionals can now anticipate that algorithms and ranking factors will continue to favor well-optimized, authoritative content on the first page of search results. This aligns with traditional SEO principles but emphasizes the need to adapt to the evolving landscape where AI models source their insights predominantly from the top search listings.
