Why I do not trust web statistics

15 Oct

Any of us that host websites like to use stats. We like to review our traffic, our hits, some of us follow our Alexa ranking or our Compete ranking. I have blogged previously about Alexa applied to ChemSpider and Compete applied to ChemSpider. The Alexa rankings and Compete rankings are available for the site online. These are PUBLIC rankings and the value of public rankings such as this is the relative ranking that you can observe…according to Compete ChemSpider unique users is about 1/2 that of PubChem and 9 times that of eMolecules.

Whether this is true or not is a whole different question. Why? Because I simply don’t believe most public stats on websites like this. For accurate measures of traffic I would choose internal Google Analytics code over any of the public website measures.

Here’s an example of how stats get distorted. I’d like to celebrate the result I am about to report but I DOUBT it’s true! Yesterday I gave a talk to a group of students and faculty at the University of Arkansas, Little Rock. The presentation is below.


Based on feedback from my host, Bob Belford, the presentation was well received. I enjoyed giving the presentation and used the BigBlueButton system to do it, using with skype for audio, and then sharing my desktop from Skype for a live demo of ChemSpider. However, I doubt it’s my best ever presentation! Within 5 hours I had received an email from Slideshare that it was being talked about on LinkedIn and was one of the top talked about presentations and they had put it on the home page of Slideshare! Overnight it had registered >10,000 views.

My Slideshare presentation on the Slideshare Home Page

Now, I wish that 10,000 people had looked at the presentation! That’s what it says now! But I believe the stats are likely biased and people have looked at the Slideshare home page 10,000 times while it was shown in the “Hot on LinkedIn” page. I may be wrong…maybe it is that popular! And if so thanks for reading.



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.
