I'm trying to fetch Post Impression data and split by Post Reach so I can create a chart of best performing post, but Supermetrics won't allow this. Any idea why or is there a non-manual way around this?
Below is the error message I receive...
Can't fetch the page_posts_impressions_unique metric when splitting by post-level dimensions
Thanks for reaching out.
When you are splitting the chart into post-level dimensions, you need to select the metrics that do not end in "of posts". Those metrics are to be used when you are fetching page totals. So please use for example the metrics shown in the attached screenshot.
