What is the Searchmetrics visibility index?

The Searchmetrics visibility index is a performance indicator developed by the German company Searchmetrics.

It measures a domain's online presence on search enginesmainly Googlebased on a set of keywords relevant to this domain. In other words, it enables us to assess a website's ability to rank in the search results (SERP) for specific queries relevant to its sector of activity.

Why use this visibility index?

This SEO visibility can be particularly useful for :

  • Evaluate the impact of actions taken as part of your natural referencing strategy,
  • Identify development opportunities in terms of keywords,
  • Benchmark digital activity by monitoring the performance of competitor sites,
  • Understand the evolution of search trends to better anticipate market needs.

In short, the Searchmetrics visibility index provides an overall view of a website's online presence, enabling you to make informed decisions in terms of natural referencing.

How is this visibility index calculated?

The calculation of the Searchmetrics visibility index is based on a formula that takes several elements into account. To simplify matters, here are the main steps in calculating this indicator:

1. Selection of keywords representative of the field

For each field analysed, Searchmetrics builds up a database of relevant keywords for the sector of activity concerned. These keywords are selected on the basis of several criteria, such as their search volume and their link with the content of the website.

2. Compilation of research data

Searchmetrics then collects the data available for these keywords, such as their search frequency, the position of the various domains in the search results, and the click-through rate (CTR) expected as a function of position.

3. Weighting of positions and calculation of the index

Finally, a score is assigned to each domain based on its position in the SERPs for each keyword. This score is weighted by the search volume for the keyword and the expected CTR for the position occupied. All these scores are then added together to obtain the Searchmetrics visibility index for the domain.

How should the results be interpreted?

Absolute value and change over time

The Searchmetrics visibility index is expressed as a number, generally between 0 and 100. A value close to 0 indicates a low online presence, while a value close to 100 reflects a high search engine presence. However, the gross result is not enough in itself: it is essential to monitor its evolution over time in order to assess the effectiveness of the SEO actions taken.

Benchmarking the competition

Comparing the evolution of your visibility index with that of your competitors allows you to situate your website in relation to the market and identify opportunities to be seized. In this way, you can adapt your SEO strategy in line with the positioning of other players in your sector.

Analysis of specific keywords

In addition, it can be interesting to look at the key words that make up the visibility index to identify those that have the greatest impact on your online presence. In this way, you can adjust your content to better meet the needs of Internet users and improve your organic traffic.

What are the limits of this visibility index?

Despite its many advantages, the Searchmetrics visibility index has certain limitations that should be taken into account when using it:

  • It only takes into account positioning in the SERPs and not the other factors impacting a website's performance (hit rate, etc.). conversionsession duration, etc.),
  • The index is based on a selection of keywords determined by Searchmetrics, which may exclude certain terms specific to your business,
  • Some variations in the index may result from updates to search engine algorithms or sudden changes in the search habits of Internet users.

So, although the Searchmetrics visibility index is a valuable tool for evaluating and optimising your SEO strategy, it should not be taken as the sole criterion for performance.

Other indicators should also be monitored, such as the click-through rate, the number of pages viewed and the bounce rate to get a complete picture of your website's success.
