No synonyms found for a brand name
Cause: Brand names and proper nouns often have no true synonyms.
Fix: Use related SEO terms instead of forcing fake substitutes.
Synonyms feel forced
Cause: A direct replacement changed the sentence meaning or flow.
Fix: Rewrite the surrounding sentence, or skip that synonym.
Primary keyword disappeared
Cause: Too many replacements diluted the main target phrase.
Fix: Keep the primary keyword in the title, H1, URL, and key intro copy.
