Google Search Console: What It Is, What It's For and How to Set It Up

When a restaurant in Gràcia tells me they don't appear on Google, or a clinic in Tarragona sees their traffic drop for no apparent reason, the first thing I open is Google Search Console. Always. Because in ten minutes this free tool already tells you where the problem is, and most business owners in Catalonia either don't know it exists or have it set up but have never looked at it.

This guide explains exactly what it is, how to get it running and, most importantly, how to read it to make concrete decisions.

1. What is Google Search Console

Google Search Console is Google's official and free platform that lets you see how Googlebot crawls, indexes and displays your website in search results. It's not a marketing or advertising tool: it's a diagnostic tool.

The distinction matters. Google Analytics tells you what users do once they arrive at your website. Search Console tells you why they arrive, or why they don't. Without both, you're working with half the available information.

It used to be called Google Webmaster Tools. The name change was cosmetic, but the utility has grown significantly since then: today it includes Core Web Vitals reports, mobile usability data, security alerts and much more.

2. What it's really for

Let me be concrete, because the generic answer of "it helps improve SEO" doesn't help you decide anything:

• See which keywords your website appears for and in what position. A florist in Girona might discover they appear at position 18 for "wedding bouquets Girona" and that by improving that specific page, they can jump to the top 5 without any other action.
• Know which pages Google doesn't index and for what exact reason: active noindex, server error, duplicate content, robots.txt block… Each reason has a different solution.
• Submit your sitemap so Google finds new pages without waiting weeks to discover them on its own.
• Analyze Core Web Vitals: loading speed, visual stability and interaction response, broken down by mobile and desktop. Google uses these metrics as a ranking factor.
• Receive alerts for manual penalties or security issues. If your website has malware or has received a penalty, Search Console alerts you. Without the tool, you might not find out until traffic has already dropped 80%.
• Analyze backlinks: which websites link to you, how many times and to which pages. Useful for understanding your authority and detecting toxic links.

3. How to set it up step by step

The process is straightforward if you follow the correct order. Where I see people get stuck is in the verification step, so I'll explain the options in detail:

1. Go to search.google.com/search-console with your business Google account, not your personal one. If you ever need to give access to an agency or an employee, it's much cleaner to keep it separate.
2. Add a property of type "Domain", not "URL prefix". Domain property covers all versions of your website: with www, without www, with http and with https. Always choose this option unless you have a very specific reason to do otherwise.
3. Verify the property. Here are your options in order of reliability:
   • DNS record (recommended): you add a TXT record to your domain provider's panel. If you use Nominalia, Dinahosting or similar, it's a matter of 5 minutes. It's the most robust verification because it doesn't depend on your website code.
   • Via Google Analytics or Tag Manager: if you already have them installed and verified, it's the quickest option. One click.
   • HTML file: you upload a file to the server. It works, but if you ever change your website or server, you might lose verification.
4. Submit your sitemap. Go to "Sitemaps" in the left menu and add the URL, which is usually yourdomain.cat/sitemap.xml. If you use WordPress with Yoast SEO or Rank Math, the sitemap already exists and updates automatically every time you publish new content.
5. Wait and observe. First indexing data arrives in 48-72 hours. Performance data (clicks, impressions, positions) takes 7 to 14 days to be representative. Don't draw conclusions in the first week.

One detail I always apply: when I set up Search Console for an e-commerce in Sabadell or a consulting firm in Hospitalet, I also add alternative domain versions (http and www) as separate properties. Not to actively monitor them, but to confirm they don't receive independent organic traffic. If they do, there's a redirect problem that needs fixing.

4. The sections you need to review

The Performance section is where you spend most of your time. The trick is to combine filters: select a specific URL and see which keywords it ranks for. Often you discover that a page ranks for keywords you hadn't anticipated, and you can optimize it to take advantage without creating new content.

5. Real errors I find on Catalan websites

Here I want to be very specific because this is what really helps you take action. These aren't theoretical errors: I've seen them repeatedly in audits of businesses in Barcelona, Girona, Tarragona and Lleida.

• Noindex active by mistake: the most common case and the most serious. It happens on WordPress sites that were developed in a test environment and the "Discourage search engines" option was never turned off. A dental clinic in Tarragona had gone 8 months without indexing any new pages for this reason. The owner believed SEO "didn't work". The fix took two minutes.
• Hundreds of 404s without redirect: typical in online stores that have remodeled their catalog and deleted products or categories without making 301 redirects. Every deleted URL without a redirect is lost authority and a bad user experience. I've seen e-commerce sites in Badalona with over 400 active 404 errors.
• Sitemap with URLs that shouldn't be there: internal search pages, URLs with session parameters, pages with noindex included in the sitemap. Google crawls them, wastes time and starts to distrust the sitemap quality. I've seen sitemaps with 3,000 URLs where about 40% were unnecessary pages.
• Core Web Vitals in red on mobile: especially in restaurants and local shops with websites full of uncompressed images or heavy sliders. A restaurant in Gràcia with a visually very polished website took over 6 seconds to load on mobile. It was losing visibility in local searches without knowing why.
• Canonicals that Google ignores: pages that declare a canonical URL but Google has decided to index a different one. When it happens, it's usually because there are contradictory signals: the declared canonical URL has less content, fewer internal links or loads slower than the version Google prefers.
• "Discovered, pending crawl": Google has found the URLs but doesn't crawl them because its queue is full. It's not an error per se, but it's a warning that your website has too much low-quality or duplicate content consuming your crawl budget. The solution isn't to wait, it's to clean up.

6. Order of action by priority

When I detect errors in Search Console, I always follow the same order. I'm sharing it with you so you can apply it yourself without needing to hire anyone for simple cases:

1. Indexing blocks (act today): active noindex by mistake, robots.txt blocks, 5xx server errors. If Google can't get into your website, nothing else matters until it's resolved.
2. 404 errors with backlinks (this week): check in the "Links" section which error URLs receive external backlinks. Redirect them with a 301 to the equivalent page or, if there isn't one, to the category or homepage. Don't lose that authority.
3. Core Web Vitals in red (this month): always start with mobile. Uncompressed images and blocking JavaScript are usually the main culprits. Tools like PageSpeed Insights tell you exactly which elements slow down loading.
4. Low CTR with many impressions (when you have time): look for keywords where you appear a lot but nobody clicks. Improve the meta title and meta description of those pages. It's a quick win that doesn't require technical changes and can increase traffic without moving your ranking.
5. Monthly review of coverage and sitemaps: to detect regressions, that is, pages that stop being indexed suddenly. It happens more often than you'd think after plugin updates or theme changes.

7. Tips to get more out of it

If you already have the basics under control and want to go a step further:

• Compare equivalent periods, not consecutive ones: if your business is seasonal (a hotel on the Costa Daurada, a school supplies store in Lleida), always compare the same month of the previous year, not the previous month. Seasonal variations can hide or exaggerate real problems.
• Filter by device in Core Web Vitals: mobile and desktop results are usually very different. Google prioritizes mobile for ranking, but many website owners only look at desktop because that's what they use themselves.
• Review the "Internal Links" report: pages that receive more internal links are usually the ones Google considers most important on your website. If your main service page doesn't receive any internal links, you're wasting authority you already have.
• Export data regularly: Search Console stores data from the last 16 months, but if you want to compare longer periods or detect long-term trends, export data weekly to Google Sheets. There are free connectors that automate this.
• Connect GSC with Google Analytics 4: from GA4 you can see Search Console data integrated into the user flow. It allows you to correlate which keywords bring visits and which of those visits actually convert.
