Key Metrics
There are dozens of numbers available across Search Console, Google Analytics, Ahrefs, and Semrush. Most of them are contextually useful but not something you need to check regularly. A handful genuinely tell you whether your SEO is working and where to focus next. This page covers those - what each metric is, where to find it, and how to interpret it honestly.
Organic clicks
The number of times users clicked through to your site from Google Search results. Found in Google Search Console under the Performance report. This is the most direct measure of whether your SEO work is producing traffic - not potential traffic, not estimated traffic, but actual people arriving from search. Track it over time, not at a single point. A consistent upward trend across weeks and months is the clearest signal that your strategy is working.
Impressions
The number of times your pages appeared in Google search results, whether clicked or not. Also in Search Console's Performance report. Impressions rising while clicks stay flat usually means your pages are gaining visibility but not compelling enough to click - which points to title tag and meta description quality rather than a ranking problem. Impressions falling is often an early warning of ranking drops before traffic visibly declines.
Click-through rate (CTR)
The percentage of impressions that result in a click. Calculated automatically in Search Console. CTR varies significantly by ranking position - according to research compiled by OwlClaw, position 1 averages 27.6% CTR, positions 2-3 average roughly 11-16%, and results beyond page one drop below 2%. If your position 1 pages are consistently below 20% CTR, the issue is not ranking - it is that your title or description is not compelling enough relative to competing results at the same position.
As First Page Sage notes, the top 3 results account for nearly 70% of all clicks on a given SERP. The practical implication: improving a page from position 4 to position 2 can be more impactful than improving a different page from position 8 to position 5. CTR analysis helps you prioritise which ranking improvements matter most.
Average position
The average ranking position of your pages for the queries that triggered them. Found in Search Console, filterable by page or by query. Use it directionally rather than absolutely - Search Console's average position is calculated across all impressions for a query, which means a page ranking position 1 for some users and position 6 for others shows an average of around 3.5. It is most useful for identifying pages stuck in positions 4-15, which represent the clearest opportunity for incremental ranking improvement. Rank tracking in dedicated tools, covered in the next page, gives you more precise position data for specific target keywords.
Organic conversions
The number of users arriving from organic search who complete a meaningful action - a purchase, form submission, email signup, or phone call. Tracked in Google Analytics 4 by marking specific events as conversions, then filtering by organic search as the traffic source. This is the metric that connects SEO to business outcomes. Traffic volume without conversion data tells you how many people visited, not whether any of it mattered. If organic traffic is growing but conversions are not, the problem is usually intent mismatch - the content is attracting the wrong audience, or the page is not leading visitors to the right next step.
Domain Rating
A score from 0 to 100 developed by Ahrefs that measures the strength of a domain's backlink profile, based on the number and quality of referring domains. Found in Ahrefs Site Explorer. Domain Rating is not a Google ranking factor - it is Ahrefs' model of what Google's own authority signals look like. It is useful for competitive benchmarking: if your top competitors sit at DR 60-70 and you are at DR 25, closing that gap is a meaningful long-term goal. For interpreting individual backlinks, First Page Sage recommends focusing on links from sites with a DR of 70 or above, as these carry the greatest weight in building your own domain authority. Semrush's equivalent metric is Authority Score, which incorporates backlink quality, organic traffic, and spam signals.
Engagement rate
In Google Analytics 4, engagement rate replaces the old bounce rate metric. A session is counted as engaged if it lasts longer than 10 seconds, includes a conversion event, or involves two or more page views. Engagement rate is the percentage of sessions that meet at least one of these conditions. A benchmark of 60% or above is generally considered strong for organic traffic, according to OwlClaw's analysis. Pages with low engagement rates from organic search are usually suffering from intent mismatch - the searcher arrived expecting something different from what the page delivered.
The metrics worth ignoring
A few numbers appear in dashboards and reports but deserve less attention than they typically receive:
- Raw keyword count. The number of keywords a page ranks for is a vanity metric. A page ranking for 400 irrelevant keywords is worth less than a page ranking in the top 3 for five well-targeted ones.
- Alexa rank / third-party traffic estimates. Third-party traffic estimates vary 30-60% from actual analytics data on average. Use them only for directional competitive comparison, never as hard benchmarks.
- Social shares. There is no reliable evidence that social shares directly influence Google rankings. Track them if social distribution matters to your content strategy, but not as an SEO metric.
