Why publishing more content is making some websites less visible

More content increases visibility only when each page has distinct intent and a clear place in the site structure

More content can reduce visibility when it creates intent overlap and redundancy (cannibalization), dilutes internal linking and authority signals, increases crawl and indexing waste, and makes your topic and entity signals harder to interpret. The fix is governance: inventory, cluster by intent, consolidate to one canonical page per cluster, prune low value pages, and rebuild clear hubs.
