Johannes Beus: It comes directly from the Google search results. There are quite a few SEO KPIs that exist parallel to Google, where providers build their own link indexes and say: This is exactly how Google does it. That is not the case with the visibility index, but rather all the data that flows in, completely one-to-one from the Google search results, is measured one-to-one directly by Google. The current status is that we track 1 million search terms in each country, i.e. carry out 1 million searches, look at the first 100 search results, then weight them according to search volume and click probability and then add them up. Depending on what you want to look at, whether you want to check a domain, a host name, directory or an individual URL, we add them up and then show you an index value for it.
Markus Hövener: According to your documentation, not only search volume and click probability count, but also search intent. What influence does that have on the whole equation?
Johannes Beus: Exactly, search intent is a kind of proxy for vietnam phone number data understanding that the click probability varies greatly depending on the search intent, or more precisely depending on the SERP layout. If you look at click probability studies or click probability analyses, you often only see the click probability for purely organic search results, i.e. where there are ten Google hits and no other elements. That no longer corresponds to reality for most Google hits, but for most keywords you now have 10, 12, 15 different Google elements, and these have a very large influence on the click probability. And that is our visualization of the fact that we have individual click probabilities for different SERP layouts. We have tracked tens of thousands of different SERP layouts and can specify different click probabilities for them.
Markus Hövener: Okay, now there is not only the visibility index, but there is a weekly one, there is a daily one and there is also the live data. Can you break that down for us? How do they differ?
Johannes Beus: Yes, I'd be happy to. That's a bit of a historical reason. As I said, right at the beginning we tracked all the data once a week, it was then processed and always published towards the end of the week or the beginning of the next week. That means that was the weekly data. Then at some point there came a demand for more current data. Then we said: OK, then we won't do it weekly anymore, we'll expand our server farm a bit and do the whole thing daily. And then a little later we changed the databases so that we could not only calculate the data daily, but also immediately when it came in. So when we measured new search results for a keyword, they were immediately written to the database and were immediately available. And that is the live data that we now make available every five minutes. But it's all the same calculation basis, it's all the same visibility index. And the current mode is such that we take a snapshot of the live data once a day, always around midnight, just before midnight, so that the data is there at midnight the next day.
