When creating a keyword list using broad match, why should you leave out misspellings and plural forms of keywords?

When using broad match keywords, you should leave out misspellings and plural forms because Google Ads can automatically include these variations for you. Broad match is Google's default and most expansive keyword match type — it automatically extends your keyword to include misspellings, plurals, synonyms, and semantically related searches. Adding these variants manually would create a bloated, redundant keyword list without any benefit, as broad match already covers them without additional setup.
