Our SEO methodology: inputs, validation and limitations
SEO Clusterizer turns keyword lists into a reviewable hypothesis for your website architecture. Similar phrases do not prove that Google expects one URL for every query. We describe our assumptions, checks and sources so you can independently evaluate the output rather than trust an opaque score.
01
Start with comparable data
Keep country, language and input sources consistent. Remove duplicates without merging different markets or stages of the buying journey merely because they share a word.
02
Cluster, then validate
Lexical and semantic techniques suggest groups; SERP comparisons are meaningful only when collected in comparable conditions. Check page types and real user intent for important queries.
03
Map and review
Assign each reviewed cluster to an existing or proposed URL, document exceptions and possible cannibalization, and publish a separate page only when it solves a distinct task.
