Expand keywords
Grow coverage with search-term silo discovery and keyword ideation, then add the winners safely.
Keyword expansion lives on the Keywords page. Two tools feed it: silo discovery groups your existing search terms into themed clusters, and ideation proposes new keyword groups around a theme. Both produce candidates you review before adding.
Discover silos from search terms
Silo discovery reads what already converts and clusters it into coherent ad-group-sized themes — the basis for tightly-themed ad groups.
Discover search-term silos for this account and show me the themes with the strongest conversion signal.This calls gads_discover_search_term_silos.
Ideate new keyword groups
Ideation goes beyond what you've already run, proposing keyword groups around a persona or theme.
Ideate keyword silos for "commercial espresso machines for offices". Group them and flag the highest-intent set.This calls gads_ideate_keyword_silos.
Add the winners
Adding keywords is bounded-safe: up to 10 EXACT-match keywords with bids within 1.5× the account average CPC auto-apply; anything larger queues for approval. A redundancy guard drops any keyword already covered by a looser enabled match type.
Structure tools — ad groups, keywords, ads — are Search-only. Performance Max and other non-Search channels sync at the campaign level; propose only budget, status, and target changes for them.
