What are common reasons Wikipedia pages get rejected?

Wikipedia rejections at Articles for Creation follow predictable patterns and most of them trace back to issues that should have been caught in the readiness assessment. Insufficient notability is the most common: the sources do not support the article’s claim to encyclopedic importance, usually because they are too few, not in-depth enough, or not independent of the subject. Promotional tone is next: language that reads as marketing copy, undue emphasis on awards or rankings, subjective adjectives describing the subject. Undisclosed COI gets the article flagged and often declined regardless of other merits. And insufficient secondary independent coverage means the third-party authoritative material is too thin to support the substance of the article. Each is fixable, but the fix is usually upstream of the article itself, in the sourcing and disclosure work that should precede submission.
