How often are links updated in the Toolbox?

The SISTRIX link database is based on a hybrid model in order to be able to provide a comprehensive and complete picture of the incoming links of a domain.

Our own link crawlers continuously search the publicly available Internet. We crawl more than a billion websites every day and collect many billions of links. The link data obtained in this way is collected every few days and included in our link database. Our own link index is fully updated about once a month.

In addition, we cooperate with partners such as Majestic SEO and others who also operate their own link crawlers and databases. We also use the links available from these sources and add them to our link index. On this basis, and with the additional evaluation of the links according to relevance by the Visibility Index of the linking hostname, we believe that we can offer the best link data currently available.
