Search Visibility Then & Now: What's the Reliable Way to Measure Your SEO Efforts?

SEO agencies have to work with hard, complex metrics to determine a benchmark for success when it comes to their keyword groups’ performance.
Analyzing a single keyword’s performance is quite straightforward as the ranking is enough – you usually see it next to some quality attributes (search volumes, SERP features, user intent) and know its status. But, once you start looking at hundreds or thousands of keywords , things change.
The problem with measuring the performance of a keyword group (and why it’s so hard to tackle it!) is that it has to take into consideration not only the rankings but also the quality attributes of those keywords.
There is this thing about complexity – Tesler’s law which states that “the total complexity of a system is constant. If you make a user’s interaction with a system simpler, the complexity behind the scenes increases.”
Enter Visibility.
If we apply Tesler’s law to SEO performance measurements, then the Visibility metric is a seemingly simple solution to understanding how your keyword groups perform, ergo, how the site stands and how likely users are to see it and interact with it. Yet, when analyzing SEOmonitor ’s Visibility, the complexity is preserved in the calculation – which makes it a reliable metric.
What follows is a short history of how search visibility came to be and why we think it’s a core metric to have, as it helps agencies connect their actions with their clients’ business results.
In this journey, we’ll take a closer look at the different kinds of visibilities with their quirks and relevancy problems, while explaining how we’ve managed to apply Tesler’s law and solved those shortcomings.
The History Behind Measuring Search Visibility
Average Position – Google Search Console
One way the SEO industry decided to solve the problem of monitoring keywords and connecting them with changing ranks is the average position. Defined in Google Search Console as the sum of positions divided by the total keywords you’re ranking for, this metric partially solves the problem of accuracy with dynamic variables.
Google also calculates the topmost position of a website for a specific keyword averaged across all keywords where it appeared.
What are the average position’s limitations?
Although it may seem like a good performance indicator to start with, it doesn’t paint the whole picture.
It gets misleading when a new keyword starts ranking, for instance. So if keyword X is in position 1 and keyword Y is in position 3, your average position will be 2. But if keyword Z enters in position 10, then the average position actually drops although your performance is improving. You’ll get a 4.6 average. That drives your attention in another part than necessary.
Mix in SERP features in the formula and things can be even more confusing, due to Google’s counting method of positions from top to bottom, making an AMP carousel a position 2, but a Knowledge Graph card a position 6. And let’s not forget that it depends on the device and location.
Also, the average position doesn’t include search volumes for the ranking keywords, so you may have a good ranking keyword with low searches, which won’t really drive traffic to the client’s site.

Yet, although they may go under the same generic name of “visibility”, these metrics differ quite a lot and have many flaws.

Keyword Stacks – Number of Keywords in top 1-3, 4-10, 11+
Another stop in the SEO industry’s quest of performance metrics: the keyword stacks, grouping them by the number of keywords in positions 1-3, 4-10, 11-20, etc.
Calculated as such, it is meant to showcase how a website is faring in search visibility based on the number of keywords in each “stack” – is it more on the top 1-3 side or on the 4-10 side?
So you will know the number of keywords generating a certain visibility number or percentage.
But there’s a catch.
What are the keyword stacks’ limitations?
Let’s say you have 50 keywords in top 3 and 150 keywords in 4-10. That can mean anything if the search volumes for each keyword are not considered, because there can be huge differences in how they impact your traffic. Maybe only 10 are relevant in terms of high search volumes for your chosen timeframe.
How do you know which ones to improve?
Also, there can be significant differences between the keywords in position 1, 2, and 3, so how do you know whether they’ve reached their best performance yet?
Visibility Metrics in the Industry
From average positions to keyword stacks, average click-through rates (CTRs) determined by all targeted keywords or based on rankings, the visibility metric is now a constant in the industry.
Yet, although they may go under the same generic name of “visibility”, these metrics differ quite a lot and have many flaws, as you’ll see below – being either iterations of the old metrics without necessarily solving their limitations or the same old metrics disguised with a new visibility name.
Let’s take a few existing visibility metrics under more careful scrutiny:
The visibility calculated as an average of positions with different scores based on rankings is, at the end of the day, still an average position. So it suffers from the same limitations – changes based on adding or deleting keywords that can be misleading, scores that don’t necessarily explain room for growth, etc.
The visibility calculated as estimated clicks based on rankings may give you a percentage that seems viable, but it’s still not reliable in showing you what those estimates mean for growth potential.
The visibility calculated as average CTR (determined by all targeted keywords) – the organic clicks are still an estimation based on the top 10 positions and beyond, so, once again, you don’t know the growth potential. Plus, SERP features are included which makes the estimation more complex and fluctuant.
To conclude: all of them suffer from historical volatility and are unreliable, as they change not just based on performance, but based on your keywords list (adding/deleting keywords).
SEOmonitor’s Solution for the Visibility Metric
It’s clear that the need to identify a visibility metric that includes keywords and rankings and makes the connection with potential business outcomes is as strong as ever.
We believe that one formula of calculation helps determine the benchmark for success, without introducing too much complexity – an impression share in the organic results, which takes into account the rankings and monthly search volumes for every keyword in your list.
Expressed as a percentage, SEOmonitor’s Visibility is an impression share weighted against search volumes, making it a more accurate representation of how well the client’s website ranks in Google at a particular time for a list of keywords.
Plus, being an impression share, you have a clear, objective scale that doesn’t fluctuate in itself – from 0% to 100% (all targeted keywords in position 1), you know the reality of the website’s status and potential (no estimation-based guesses).
Why does it work in telling you the truth about your SEO performance better than other metrics of its kind?
Because it includes search volumes, it helps you correlate your traffic data with seasonality and search trends. Also, due to our split of brand and non-brand organic traffic , focusing on the latter, you’ll know how search trends and seasonality impact your visibility. So it’s a performance-related metric which you can explain, optimize etc.
We include automatic annotations on the Visibility graph every time there is a non-performance change, like including or excluding keywords from the campaign – while excluding the “false impact” from your performance.
The explainer for enhanced transparency that shows you why you have certain visibility trends – we show you how rank changes and search trends affected the visibility for each keyword group in your campaign, and highlight the most impactful keywords.
If you need a metric that tells you the truth about your keyword groups fast, look no further!
SEOmonitor’s visibility is for groups like the rank is for the individual keyword, making it a good “compass” that shows you where you are and where you can go from here.
What Are Its Limitations?
This connection with search trends can be tricky sometimes and, in order to understand changes in the Visibility, you need to look at year over year search data and see how search volumes changed.
SERP features are also a prickly matter – as they take their share from the total search volume of a keyword, a calibration is required to paint the whole picture regarding the Visibility metric. This is actually something we’re currently developing at SEOmonitor for this quarter – so you’ll know the percentage from the total searches that actually end up clicking on your targeted site.
