Keyword Cannibalisation

Keyword Cannibalisation is a problem that can occur when multiple pages on a website target the same keyword (whether intentionally or not). You dilute your ability to rank for the keyword across these pages. You should try to avoid this if you can by using keyword clustering.

Keyword Clustering

Keyword Clustering is the process of grouping together related keywords to cover them on the same page (or group of related pages) to avoid Keyword Cannibalisation. Keyword Clustering is best carried out by using SERP Clustering.

Keyword Difficulty

A measure that some keyword research tools will assign to keywords to try to indicate how difficult it would be to rank for a certain keyword based on competition. However, they don’t factor in that this difficulty level will vary depending upon the site that is trying to rank for the keyword and how much topical authority it may or may not have in the area.
