Have you typed “why did my Google rankings drop?” or “why am I losing position on Google?” and found yourself staring at collapsing graphs in your analytics dashboard? In September 2025, many site owners and SEO professionals were caught off guard by a sudden “rankings crash” that had little to do with their sites and everything to do with changes at Google.
For years, power users could override Google’s default 10‑result limit by adding &num=100 to the end of a search URL. This trick displayed 100 results on a single page, making it easy for rank‑tracking tools and SEOs to collect deep search data and analyse competition. However, Search Engine Roundtable reports that the parameter now works only about half the time and appears to have stopped working entirely. Without warning, Google removed this parameter, which means tools and users can no longer reliably fetch a full list of results.
What Changed in September 2025?
Google seems to be testing the removal of the “100 results” parameter across accounts. According to coverage from Search Engine Roundtable, users noticed that the &num=100 parameter worked in some sessions and not in others, and eventually stopped working altogether. The disappearance of this parameter has had a ripple effect because rank‑tracking tools typically rely on those deeper results to calculate visibility across hundreds of keywords.
SEOs also observed unusual behaviour tied to this test. For example, the parameter might work when you’re signed out of your Google account but not when you’re signed in. Some professionals suspect that the change is related to new anti‑bot or anti‑scraping measures—Search Engine Roundtable notes that even automated rank trackers using headless browsers encountered random captchas and failures.
Why Your Ranking Reports Look Worse
Because rank‑tracking tools depend on the &num=100 parameter, removing it forces them to make multiple requests to gather the same amount of data. Many tools are still adapting. In the meantime, they may record only the first page of results or fewer, which makes your rankings appear to plummet. This is why you might see a massive decline in reported Google rankings even though your actual traffic or conversions haven’t changed.
It’s also affecting impression counts. Google Search Console counts an impression when your result appears within the first 100 positions. If tracking tools can’t access deeper positions, you’ll see fewer impressions and an inflated “average position,” which again looks like a dramatic drop when it’s really a reporting glitch.
Reasons Behind the Change
Google hasn’t issued an official explanation. Industry observers speculate that the removal of the &num=100 parameter could be tied to anti‑bot enforcement, experiments with AI‑powered search interfaces, or efforts to streamline the user experience. The timing coincides with recent spam‑fighting and quality updates, so limiting bulk scraping may be part of the goal. For now the safest assumption is that the change is permanent, and tools need to adjust to the new reality.
How to Adapt Your SEO Strategy
- Trust your first‑party data. Use Google Analytics and Search Console to monitor actual traffic, impressions and conversions rather than relying solely on third‑party rank reports.
- Check critical rankings manually. For your most important keywords, perform live searches in an incognito window to confirm their real positions.
- Focus on top‑page visibility. The top 10–20 positions matter most for traffic. Deeper rankings will continue to fluctuate as tools recalibrate.
- Communicate with clients and stakeholders. Let them know the sudden drops are a data‑collection issue. Link to credible reports, such as the Search Engine Roundtable article, so they understand the context.
- Stay informed on tool updates. Rank‑tracking providers are rolling out fixes that rely on more sophisticated scraping or API data. Keep an eye on their announcements and adjust your reports accordingly.
Final Thoughts
The sudden crash in your reported rankings isn’t a result of Google penalizing your site. It’s the consequence of a behind‑the‑scenes change to how many results Google returns per page. Until tools adapt, base your decisions on real traffic and user engagement, not temporary fluctuations in rank‑tracker dashboards. When communicating with your team or clients, emphasise that the issue is external and link to authoritative sources for verification. As the search ecosystem evolves, focusing on quality content and user experience remains the most reliable strategy for long‑term SEO success.
