The Issues by Priority connector will show a distribution of onsite optimization issues by type (errors / redirects / meta data / etc).
There are two ways of using this connector, which you must choose when selecting a Report Type setting up the data source.
Choosing Trend will return a list of the number of issues by type for each crawl date.
Choosing Comparison will show the number of issues by type for the most recent crawl, and the amount each has changed since the previous crawl.
If desired, you can create multiple data sources with this connector to use it in both Trend and Comparison modes in the same report.
