EVISA's web portal: User statistics

The EVISA web portal at www.speciation.net, being on-line without any interruption more than 20 years, has been visited by more than 20 Million visitors until now.

The EVISA web portal at www.speciation.net, providing valuable speciation related information on more than 17,500 pages is without doubt the primary information site for all those interested in trace element and speciation analysis. It is our faithful user community that tells us that the information value provided by EVISA is highly accepted.

We have actually welcomed more than 20 Million visitors on EVISA's webportal (October 2023), about 1.75 Million during the year 2023. The users have downloaded about 8.2 Mio. pages during the year 2023.

Our user community started to grow at a significant rate with the beginning of 2007, when EVISA opened its German office in Münster. In 2011 we nearly doubled the number of visits compared to the previous year. Since then our user community was still increasing, although at a lower rate. We are continuously analysing the user activity and are using the information to improve the versatility of the site. After 2020 we were down-rated by Google and other search engines, because of missing HTTPS support. In September 2022 we updated our server to fully support the HPPS protocol, and since then we regained the lost part of our user community.
