Lost Traffic Overnight? Here’s How to Troubleshoot SEO Drops Using GSC
Simran July 7, 2025 36 views


There’s no worse feeling for a digital marketer than opening Google Analytics and seeing a nosedive in your website traffic overnight. It’s the kind of moment that sends your heart racing, especially when you don’t know why it happened.

But before panic sets in, there’s good news: Google Search Console (GSC) gives you some of the most powerful diagnostic tools to identify and fix what went wrong.

At RepIndia, we’ve worked with numerous brands across India, from startups to enterprise clients, who’ve faced sudden drops. And time and again, our starting point has been the Google Search Console URL Inspection tool.

Let us walk you through a strategic and analytical approach to troubleshooting SEO traffic drops using GSC, bringing in both technical nuance and real-world insights that top providers of SEO services in Delhi NCR and other areas of India rely on.

6-Steps to Troubleshoot SEO Traffic Drops Using Google Search Console

Step 1: Confirm the Drop (Don’t Just Go by GA)

First things first: confirm the traffic loss isn’t just a data glitch. Check Google Search Console’s Performance tab to compare the affected date range with the previous period. Look at metrics like total clicks, total impressions, average CTR and average position, for instance.

This helps isolate whether the dip is due to visibility issues on Google or a misfiring analytics setup. If GSC confirms the drop, it’s time to go deeper.

Step 2: Use the URL Inspection Tool to Investigate Key Pages

One of the most overlooked yet mission-critical features of GSC is the Search Console URL Inspection tool.

Start by identifying which URLs lost the most traffic. Plug them into the Google Search Console URL Inspection tool to check:

  • Is the page still indexed?
  • When was it last crawled?
  • Are there crawl or indexing issues?
  • Is the canonical set correct?

In one case, a client’s product pages were mistakenly set to “noindex” after a CMS update. GSC’s inspection tool flagged this instantly, helping us course-correct before the drop became permanent.

Step 3: Check Coverage & Indexing Issues

Next, go to Index > Pages in GSC and sort through:

  • Pages with errors (especially 404, 500, or redirect errors)
  • Pages excluded from indexing
  • “Discovered – currently not indexed” or “Crawled – currently not indexed”

These statuses may indicate crawl budget issues or poor-quality content. For example, if a large number of new blog pages are showing up under “Crawled – not indexed”, it may be time to reevaluate content depth, originality, or technical SEO like schema.

This is also where working with professional SEO agencies in Bangalore or other regions can help. We often find hidden technical issues that clients miss entirely, like broken internal links or accidental noindex tags.

Step 4: Investigate Algorithm Updates

Google rolls out multiple updates every year – some broad, some targeted (like helpful content or spam updates). A sudden drop in traffic could coincide with such an update.

Use tools like the Google Search Status Dashboard to identify whether an update hit your sector or region.

If yes, go back to your affected pages and ask:

Step 5: Compare Queries & Devices

Head back to the Performance report in GSC, and filter by:

  • Queries (which ones dropped?)
  • Devices (was it mobile-specific?)
  • Countries (did the drop affect one region?)

We once worked with a Bangalore-based edtech client whose mobile traffic plummeted. Turns out, a rendering issue broke mobile navigation on key landing pages. No indexing problem: just bad UX.

That’s where GSC shines. Its granular data can often reveal things that raw traffic numbers can’t.

Step 6: Re-inspect & Request Indexing (When Needed)

After identifying the issue, be it fixed content, resolved canonical conflicts, or updated meta tags, don’t just wait around. Use the Search Console URL Inspection to request a fresh crawl.

This is especially useful for post-site migrations or technical overhauls. The faster Google crawls and re-indexes your content, the faster you recover.

Bonus: Keep an Eye on Internal Linking & Sitemaps

Another silent traffic killer? Broken internal linking.

Pages may not drop out of the index but their link equity weakens, causing them to lose rankings. GSC won’t show this explicitly, but a sitemap resubmission, followed by URL inspections, can reveal if some pages have become “orphaned”.

The Wrap-Up: Traffic Drops Are Fixable With the Right Tools

So, did you really lose traffic overnight? Or did something silently change in your site’s technical health, content quality, or crawl behavior?

The Google Search Console URL Inspection tool isn’t just for developers or SEOs, it’s a front-line defense mechanism. When used strategically, it gives you exactly the kind of clarity most marketers crave in crisis situations.

At RepIndia, we treat traffic drops not as dead ends but as diagnostic puzzles. And GSC? It’s our best diagnostic kit. If you’re a brand in Delhi NCR or a startup teaming up with SEO agencies in Bangalore, knowing how to read and use GSC data is essential for making smart, strategic decisions.
