Google Search Console Guide: Using Data to Improve Your SEO
Google Search Console is a free tool provided by Google that shows how your website performs in organic search — which queries trigger your pages, how often they appear, how many clicks they receive, and what technical issues Google has detected. Every website running an SEO strategy should have Search Console configured and checked regularly; it is the most direct window into how Google actually sees and interacts with your site.
This guide covers the core reports in Google Search Console, what to look for in each, and how to turn the data into actionable SEO improvements.
Setting Up Google Search Console
To access Search Console data, you must first verify ownership of your website. Google offers several verification methods: adding an HTML tag to your site’s <head>, uploading a verification file, using your Google Analytics or Tag Manager connection, or adding a DNS record. For WordPress sites, the HTML tag method via your theme’s header or a plugin like RankMath is the simplest. Once verified, Search Console begins collecting data — historical data is not retroactive, so set it up as early as possible.
The Performance Report: Your Most Important SEO Data
The Performance report shows clicks, impressions, average click-through rate (CTR), and average position for each query, page, device, and country. This is the report you should review at least monthly — ideally weekly for active campaigns.
What to Look For
- High impression, low CTR queries: Pages appearing frequently but rarely clicked. This signals a meta title or description that is not compelling enough — improving it can lift traffic without any change in rankings.
- Queries ranking 8–15: Pages just off page one. These are your highest-leverage ranking improvement opportunities — they already have some authority and may need only content improvements or a few additional links to reach position one to five.
- Unexpected query matches: Your pages appearing for queries you did not intend to target — revealing content gaps or keyword cannibalisation issues.
- Position trends: Comparing periods (month over month, year over year) to identify which pages are gaining or losing ground and why.
Coverage Report: Understanding Indexing Issues
The Coverage (now called Indexing) report shows which pages Google has indexed, which it has attempted to index but excluded, and which have errors preventing indexing. Key statuses to monitor:
- Excluded — Crawled, not indexed: Google reached the page but chose not to include it. Often signals thin content, near-duplicate pages, or a noindex tag applied unintentionally.
- Excluded — Discovered, not crawled: Google knows the page exists but has not crawled it. May indicate crawl budget issues on large sites or internal link deficiencies on the specific page.
- Errors: Redirect errors, server errors (5xx), or submitted URLs blocked by robots.txt — all prevent ranking and need immediate resolution.
Core Web Vitals Report
Search Console’s Core Web Vitals report shows real-user performance data for your site’s pages, categorised as Good, Needs Improvement, or Poor for both mobile and desktop. Pages with Poor status on LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), or INP (Interaction to Next Paint) are eligible for demotion in rankings. Investigate specific failing URLs and identify the underlying cause — typically unoptimized images, render-blocking scripts, or unstable layout elements.
Links Report: Understanding Your Backlink Profile
The Links report shows which external sites link to yours (and to which specific pages), plus which pages have the most internal links pointing to them. Use this to:
- Identify your most-linked pages and understand what link acquisition is working
- Spot internal linking gaps — pages with no or few internal links are harder for Google to prioritise
- Verify that link-building activity is producing new referring domains over time
Manual Actions and Security Issues
If Google has applied a manual penalty to your site, it appears in the Manual Actions report with a description of the violation. Security issues (hacked content, malware, phishing) appear in the Security Issues report. Both require immediate attention — penalised sites experience significant ranking suppression until the issue is resolved and a reconsideration request is submitted and approved.
Using Search Console Data Alongside On-Page Optimisation
Search Console tells you which queries trigger your pages. Cross-reference this with your current page content to find keyword alignment gaps — queries you are appearing for but have not explicitly optimised for. Use our Keyword Density Checker to evaluate whether your target keyword appears at the right frequency in your page content, then iterate.
Common stop words (the, a, in, of…) are excluded from 2 and 3-word phrase results to surface meaningful phrases.
For the broader SEO context these reports fit into, see our 12-Month SEO Strategy Guide and our Technical SEO Audit walkthrough, which covers the fixes Search Console data typically surfaces.
Nexsage’s SEO services include full Search Console setup, ongoing monitoring, and monthly performance reporting — so you always know what the data says about your site’s visibility.
Chat on WhatsAppFrequently asked questions
What is Google Search Console used for?
Google Search Console shows how your website appears in Google search results — which queries trigger your pages, how many clicks and impressions each page receives, what technical indexing issues exist, and how your Core Web Vitals perform.
Is Google Search Console free?
Yes. Google Search Console is a free tool available to any verified website owner. There are no paid tiers or usage limits on the data it provides.
How often should I check Google Search Console?
For active SEO campaigns, weekly review of the Performance report and monthly review of Coverage and Core Web Vitals is appropriate. Set up email alerts for manual actions and security issues so these are flagged immediately.
What does 'crawled but not indexed' mean in Search Console?
It means Google visited the page but chose not to include it in the search index. Common causes include thin or duplicate content, very low internal link authority, or an unintentional noindex directive on the page.
Can Google Search Console show me all the keywords I rank for?
Search Console shows queries for which your site received at least one impression in the past 16 months. It does not show every keyword you theoretically rank for — only those where your pages actually appeared in results.
