Resolution reports are sent out via email at the beginning of each month and includes statistics about DOI resolutions from the previous month. Resolution reports are sent by default to the business contact provided for your organization, but we can add or change the recipient(s) as needed.
A separate report is generated for each DOI prefix. The statistics are based on the number of DOI resolutions through the DOI proxy server (https://0-doi-org.wam.leeds.ac.uk/) on a month-by-month basis. These statistics give an indication of the traffic generated by users clicking DOIs. The DOI links are largely from links in other publishers' journal references to articles, but they are also from DOI links in secondary databases, links from libraries using DOIs, and even DOIs in used in print versions.
The report includes:
- Resolution failure rate: the percentage of DOI resolution attempts that failed. The prefix failure rate and the overall failure rate (for all Crossref members) are also included.
- Resolutions by month: total number of resolutions per month for the past 12 months, by prefix (Count) and overall (All Members).
- Resolution stats: resolution counts for the report prefix.
- Top ten DOIs:list of the ten DOIs with the highest number of successful resolutions for the month, and the number of times each DOI was successfully resolved.
- Failed DOIs: a list of DOI resolution attempts that failed (i.e. resolved to a Handle error page). This list is presented as a .csv file attached to the report email and contains both the failed DOI and number of failures.
We do our best to filter out known search engine crawlers. The overall number of filtered crawler resolutions for the month is included in the report.
See Working with your resolution report for tips on troubleshooting high failure rates.
What is a resolution?
When a researcher clicks on a DOI link for an article, that counts as one DOI resolution. For example, clicking on https://0-doi-org.wam.leeds.ac.uk/10.1038/nature02426 counts as one resolution to Nature. No information is captured about who the user is or where they are coming from. The information on DOI resolutions is captured by the web server logs on https://0-doi-org.wam.leeds.ac.uk/ which is run by CNRI on behalf of the International DOI Foundation. These numbers are not a precise measure of traffic to a publisher's website - cached articles, search engine crawlers not following re-direction, and traffic that is directed to a locally appropriate copy through a library link resolver would be included in these numbers, but would not result in inbound traffic to a website. Nevertheless, these numbers provide an important measure of the effectiveness of a member's participation in Crossref.
