Google Search Console is Google’s free service for website owners that shows how a site performs in Google Search: which searches it appears for, how often people click, which pages are indexed and what problems Google has found. It was called Google Webmaster Tools until 2015, and it is the only place you get this data directly from Google.
How Google Search Console works
You add your site as a property and prove you own it. A domain property covers every version of the site (with and without www, http and https, every subdomain) and is verified with a DNS record at your domain registrar. A URL-prefix property covers only one exact address and can be verified with an HTML file, a meta tag, Google Analytics or Google Tag Manager. Once verified, you can see the reports for that property, and you can add other people as users without sharing your login.
The main areas are worth knowing by name:
- Performance. The Performance report shows clicks, impressions, click-through rate and average position, broken down by query, page, country, device, search appearance and date, with up to 16 months of history.
- URL Inspection. Checks a single URL: whether it is indexed, which canonical Google chose, when it was last crawled and how the page rendered.
- Pages. The Page indexing report lists which URLs are indexed and, for those that are not, the reason.
- Sitemaps. Where you submit your XML sitemap and see whether Google could read it.
- Experience, Links, Manual actions and Security issues. Core Web Vitals from real users, a sample of internal and external links, and any penalties or hacking Google has detected.
Data usually runs a couple of days behind, and Google hides very rare queries for privacy, so query totals will not add up exactly to the site totals.
Why it matters
For a UK business, Search Console answers questions no other tool can answer with Google’s own numbers. Set the Country filter in the Performance report to United Kingdom and you see UK-only clicks and impressions, which matters if your site also attracts visitors from abroad who will never become customers. Compare that with the unfiltered view and you often find that a page you thought was performing well is mostly read by people outside the UK.
It is also the early-warning system. A sudden spike in pages marked “Crawled, currently not indexed”, a manual action notice or a security warning will appear here first. Owners who never open Search Console tend to discover these problems months later, through a drop in enquiries.
It complements rather than replaces Google Analytics 4. Search Console tells you what happened in Google before the click; GA4 tells you what visitors did after they arrived.
Common mistakes
- Verifying only one version of the site. A URL-prefix property for https://www misses data for other versions. Use a domain property where you can.
- Losing access when an agency or developer leaves. Keep ownership in an account the business controls and add others as users.
- Reading average position as a ranking. It is an average across every search where the site appeared, so one page’s figure can blend very different queries.
- Ignoring the Country and Device filters. Totals mix UK and overseas traffic, mobile and desktop.
- Clicking “Validate fix” without fixing anything. Validation only re-checks; it does not solve the underlying issue.
How to act on it
Set up a domain property today if you do not have one, and make sure the business owns it. Submit your sitemap. Then build a monthly habit: open Performance, filter to United Kingdom, compare the last 28 days with the same period last year, and look at which queries and pages moved. Check the Pages report for any growth in excluded URLs and read every email Search Console sends.
When the reports point to crawling, indexing or rendering faults you cannot explain, that is the point where technical SEO support pays for itself, because the fix is often a template or server setting rather than the page itself.
