What is alphabet soup keyword research?
Appending every letter (a-z) to a seed to uncover the full autocomplete universe around a topic.
Suffix or prefix — which is better?
Generate both. Suffix finds modifiers after the seed, prefix finds question words and prepositions before it.
How many variations per seed?
Up to 36 suffix + 36 prefix combinations per seed (a-z plus 0-9).
