ChemSpider Usage Continues to Grow In a Linear Fashion

10 Sep

This past week I received some inquiries and comments regarding the traffic coming to the ChemSpider Site. It was commented that it was not possible to compare eMolecules traffic and ChemSpider traffic on Compete. I confirmed this and have now registered ChemSpider so that this should be possible in the future. There are many Analytics tools out there to measure traffic at a site. We use Weblog Expert at our site for our internal analytics tool. The plot below shows a fairly linear growth in the number of unique visitors to the ChemSpider site since we went live on March 27th, just in time for the Spring ACS.

We also use Alexa to browse our performance. The statistics are shown below for the increase in global users accessing the site, the overall traffic rank and the number of page views per user.

Alexa Rank 1

The geographical distribution of visitors is actually quite surprising. Until recently the UK was actually the most popular visiting country but the US visits increased dramatically when we integrated the announcement regarding the Patent Searching went online. What is quite surprising is the low number of visitors from Germany, China and India. Based on my previous experiences in the chemoinformatics world I would expect Germany to be much HIGHER and certainly there should be increased traffic from India. That said, India wasn’t even on the list a week ago and is growing now as the message spreads. If any of you can help spread the message outside of the USA please do!

Alexa Rank 2

Addressing the original statement about being unable to compare stats on I’ve shown the geographical traffic ranks for eMolecules. Clearly there are a lot more countries for ChemSpider to provide value to! Hopefully our penetration will increase with time.

Interestingly, there are also all types of rumors about the validity of Alexa but Alexa challenge this. It’s difficult to know what’s right so what’s reported here is simply what’s given online. What we are happy to report is an ongoing growth in the usage of the system. It validates our efforts.


About tony

Antony (Tony) J. Williams received his BSc in 1985 from the University of Liverpool (UK) and PhD in 1988 from the University of London (UK). His PhD research interests were in studying the effects of high pressure on molecular motions within lubricant related systems using Nuclear Magnetic Resonance. He moved to Ottawa, Canada to work for the National Research Council performing fundamental research on the electron paramagnetic resonance of radicals trapped in single crystals. Following his postdoctoral position he became the NMR Facility Manager for Ottawa University. Tony joined the Eastman Kodak Company in Rochester, New York as their NMR Technology Leader. He led the laboratory to develop quality control across multiple spectroscopy labs and helped establish walk-up laboratories providing NMR, LC-MS and other forms of spectroscopy to hundreds of chemists across multiple sites. This included the delivery of spectroscopic data to the desktop, automated processing and his initial interests in computer-assisted structure elucidation (CASE) systems. He also worked with a team to develop the worlds’ first web-based LIMS system, WIMS, capable of allowing chemical structure searching and spectral display. With his developing cheminformatic skills and passion for data management he left corporate America to join a small start-up company working out of Toronto, Canada. He joined ACD/Labs as their NMR Product Manager and various roles, including Chief Science Officer, during his 10 years with the company. His responsibilities included managing over 50 products at one time prior to developing a product management team, managing sales, marketing, technical support and technical services. ACD/Labs was one of Canada’s Fast 50 Tech Companies, and Forbes Fast 500 companies in 2001. His primary passions during his tenure with ACD/Labs was the continued adoption of web-based technologies and developing automated structure verification and elucidation platforms. While at ACD/Labs he suggested the possibility of developing a public resource for chemists attempting to integrate internet available chemical data. He finally pursued this vision with some close friends as a hobby project in the evenings and the result was the ChemSpider database ( Even while running out of a basement on hand built servers the website developed a large community following that eventually culminated in the acquisition of the website by the Royal Society of Chemistry (RSC) based in Cambridge, United Kingdom. Tony joined the organization, together with some of the other ChemSpider team, and became their Vice President of Strategic Development. At RSC he continued to develop cheminformatics tools, specifically ChemSpider, and was the technical lead for the chemistry aspects of the Open PHACTS project (, a project focused on the delivery of open data, open source and open systems to support the pharmaceutical sciences. He was also the technical lead for the UK National Chemical Database Service ( and the RSC lead for the PharmaSea project ( attempting to identify novel natural products from the ocean. He left RSC in 2015 to become a Computational Chemist in the National Center of Computational Toxicology at the Environmental Protection Agency where he is bringing his skills to bear working with a team on the delivery of a new software architecture for the management and delivery of data, algorithms and visualization tools. The “Chemistry Dashboard” was released on April 1st, no fooling, at, and provides access to over 700,000 chemicals, experimental and predicted properties and a developing link network to support the environmental sciences. Tony remains passionate about computer-assisted structure elucidation and verification approaches and continues to publish in this area. He is also passionate about teaching scientists to benefit from the developing array of social networking tools for scientists and is known as the ChemConnector on the networks. Over the years he has had adjunct roles at a number of institutions and presently enjoys working with scientists at both UNC Chapel Hill and NC State University. He is widely published with over 200 papers and book chapters and was the recipient of the Jim Gray Award for eScience in 2012. In 2016 he was awarded the North Carolina ACS Distinguished Speaker Award.
