I firmly suspect that one of my client's sites has a severe keyword cannibalization issue.
One of the most critical pages fell into page 4 earlier this year. I checked GSC for the main keyword, and six other URLs rank for that exact keyword.
Maybe the other URLs are site links? I feel that I need more proof before I start suggesting changes, so here's my question:
What methods do you use to identify keyword cannibalization? Specific tools? As the title mentions, I would like to use the data from GSC as a proof for my client as the client is particular about using GSC data whenever possible.
