How to Use Google Search Console to Find SEO Issues

Learn how to identify and fix technical SEO errors, indexing issues, and performance bottlenecks using Google Search Console.

Sarah 9 February 2026

Think of Google Search Console (GSC) as a direct hotline between your website and Google. It’s the only place where Google tells you exactly what’s wrong with your site, which pages are being ignored, and why you might not be showing up for Brisbane locals searching for your services.

Most business owners check their traffic once a month and stop there, but GSC is actually a powerful diagnostic tool. If your SEO performance has dipped or you've launched a new site and nothing is happening, the answers are buried in these reports. Let’s dig them out.

Prerequisites: What you’ll need

Before we start, make sure you have:
  • Verified access to Google Search Console: If you haven't set this up yet, you'll need access to your domain provider (like GoDaddy or VentraIP) or your website's backend.
  • A Sitemap URL: Usually yourdomain.com.au/sitemap.xml.
  • A cup of coffee: Some of these technical reports can be a bit dry, but they are goldmines for your Google rankings.

Step 1: Check Your 'Indexing' Status

This is the most important place to start. If Google hasn't indexed your pages, they don't exist in search results. Period.
  • Log in to Google Search Console.
  • On the left-hand sidebar, click on Indexing > Pages.
  • You’ll see a graph with two colours: Grey ('Not indexed') and Green ('Indexed').
What to look for: It is perfectly normal to have more grey pages than green ones (Google often ignores junk pages like 'reply-to-comment' links). However, if your main service pages or latest blog posts are under 'Not indexed', we have a problem. Screenshot Description: You should see a bar chart. Look for the 'Why pages aren't indexed' table below the chart. This lists the specific reasons Google is avoiding certain parts of your site.

Step 2: Diagnose '404 Not Found' Errors

Under that same 'Pages' report, look for the reason: "Not found (404)".

When you delete a page or change a URL without a redirect, Google gets frustrated. If a local customer clicks a link to your site and hits a 404, they’ll bounce back to the search results, which tells Google your site isn't helpful.

  • The Fix: Click on the 'Not found (404)' row to see the list of URLs. If these are old pages that used to have traffic, you need to set up a 301 Redirect to the most relevant new page.
Pro tip:* Don't worry about weird URLs that look like gibberish or spam—hackers often probe sites for vulnerabilities. If you didn't create the page, you don't need to fix it.

Step 3: Fix 'Crawled - currently not indexed'

This is where most people get stuck, and honestly, the interface doesn't help much here. This status means Google knows the page exists and has visited it, but decided it wasn't good enough to show in search results. Why this happens in an Australian context: Often, small business sites have 'thin content'. If your 'Plumbing Services Brisbane' page only has two sentences and a phone number, Google might think it's not useful enough to index.
  • The Fix: Go back to that page and add more value. Add 300-500 words of helpful text, some original photos of your work, and perhaps a few local testimonials. Once updated, click 'Validate Fix' in GSC.

Step 4: Check Your 'Core Web Vitals' (The Speed Test)

Google cares deeply about user experience. If your site takes forever to load on a mobile phone over a patchy 4G connection in the suburbs, your rankings will suffer.
  • Click Experience > Core Web Vitals.
  • Check both the Mobile and Desktop reports.
What you'll see: Google uses a traffic light system. Green is 'Good', Yellow is 'Needs Improvement', and Red is 'Poor'.
  • Common Culprit: Huge images. If you’ve uploaded a 5MB photo of your team directly from an iPhone, it’s killing your page speed.
Quick Fix:* Use a tool like TinyPNG to squash your images before uploading them to WordPress or Squarespace.

Step 5: Identify 'Mobile Usability' Issues

Since 2019, Google has used 'Mobile-First Indexing'. This means Google looks at the mobile version of your site to decide how high to rank you, even for people searching on desktops.
  • Click Experience > Mobile Usability (Note: Google is migrating this into the 'Page Experience' report, so don't worry if it looks slightly different).
  • Look for errors like "Text too small to read" or "Clickable elements too close together".

This is often an issue with your website's 'Theme'. If your buttons are so close together that a thumb can't hit one without hitting the other, Google will penalise you. This is a technical SEO issue that usually requires a quick tweak from a developer or a change in your site's font settings.

Step 6: Find Your 'Hidden' Keyword Opportunities

This isn't an 'error', but it's the best way to find SEO growth opportunities.
  • Click on Performance > Search results.
  • Check the boxes for 'Average CTR' and 'Average position' so they light up.
  • Scroll down to the table and filter by 'Queries'.
The 'Low Hanging Fruit' Strategy: Look for keywords where your position is between 7 and 15. These are pages that are on the bottom of page one or the top of page two. The Fix: If you see you're ranking at position 12 for "Best electrician North Lakes", go to that page and add that exact phrase into a sub-heading (H2). Usually, a few small tweaks to a page that is almost* there will push it into the top 5 results.

Step 7: Inspect a Specific URL

If you've just fixed a page and you're impatient (we've all been there), use the URL Inspection Tool. It’s the big search bar at the very top of the screen.
  • Paste the URL of the page you just updated.
  • Click 'Request Indexing'.

This tells Google, "Hey, I've made changes, please come and look at this page right now." It doesn't guarantee instant ranking, but it speeds up the process significantly. (Note: Don't do this for every page on your site; Google has a daily limit. Save it for your most important pages.)

Step 8: Monitor Your 'Security & Manual Actions'

This is the 'In Case of Emergency' section.
  • Click on Security & Manual Actions.
  • Click Manual actions.

Ideally, you want to see a green tick and the message: "No issues detected." If you see a warning here, it means a human at Google has reviewed your site and decided you’ve broken their rules (e.g., buying dodgy backlinks or 'keyword stuffing'). If this happens, you’ll likely need professional help to recover.

Similarly, the Security issues tab will tell you if your site has been hacked or contains malware. Check this at least once a quarter.

Common Mistakes to Avoid

  • Panicking over 'Excluded' pages: Not every page needs to be in Google. Your 'Privacy Policy', 'Login' pages, and 'Thank You' pages should stay excluded.
  • Fixing everything at once: SEO is a slow game. Pick the 5 most important pages on your site and fix those first. Don't try to resolve 500 errors in one weekend.
Ignoring the 'Validation' button: After you fix an issue, you must* click 'Validate Fix' in GSC, or Google will keep showing the error in your dashboard even if it's gone.

Troubleshooting

"I don't see any data in my Performance report!" If you've just set up GSC, it can take 48–72 hours for data to start appearing. If it’s been longer, check that you've verified the correct version of your site (e.g., https:// vs http://). "Google says my sitemap 'Could not be fetched'." This is a classic GSC bug. Often, if you click on the sitemap status and it's red, it's just a temporary glitch. Try re-submitting the sitemap URL. If it still fails, check if you have a 'NoIndex' tag in your WordPress settings. "My mobile usability says 'Error', but it looks fine on my iPhone!" Google's bot sees things differently. Use the 'Test Live URL' button inside the URL Inspection tool to see a screenshot of how Google 'sees' your mobile site. Often, a script is being blocked that makes the page look broken to the bot.

Next Steps

Finding the issues is only half the battle. Now you need to implement the fixes:
  • Update your content: Start with those 'Crawled - currently not indexed' pages.
  • Compress your images: Fix those Core Web Vitals errors.
  • Set up redirects: Clean up those 404 errors so users don't get lost.
