Monitoring a website’s visibility index is a key part of online marketing. The visibility index helps to rank and find a website in search engines. Below are the most common tools to track the visibility and traffic of a website.
What is the Visibility Index and why is it important?
The visibility index shows how present a website is in search engine results – i.e. how often and on which positions it appears for relevant search terms.
The position of the website for selected keywords and the search volume of these keywords are taken into account. A high visibility index usually indicates a good findability of the website.
How is the Visibility Index calculated?
The calculation differs depending on the provider (such as Sistrix, SEMrush, Ahrefs or Xovi), but follows similar basic principles:
- Keyword set: A fixed collection of search terms that is checked regularly.
- Ranking position: The placement of the website for these keywords.
- Search volume: The frequency with which a keyword is searched.
- Click probability: The probability that users click on the website depending on the position.
These factors result in the index value that reflects the visibility of a website.
Why is it worth observing the visibility index?
- Performance overview: Recognize whether your own SEO measures work.
- Comparison of competition: Classification of one’s own position vis-à-vis the competition.
- Early warning system: A sudden decline may indicate Google updates or technical issues.
