It seems that landing page data for those clicks where user click the site link is not available in the Landing Page Report. We are downloading this report from the API to analyze the landing pages performance but the site links urls data is missing in the report.
We have these sitelinks clicks landings in our internal logs with valid GCLID(verified from click performance report) that confirms that sitelink URL was used for the landing page but data for the same URL is missing in the Landing Page Report.
Some data in the report has two dashes ( -- ) for the ExpandedFinalUrlString field, I think these row contain the aggregate data for site links but the site links URL is missing that we need for the analysis.
We are using the below report definition xml.
