How this service works
Google Trends related queries for a keyword. Returns the searches people run alongside a keyword in a given country: top queries scored 0-100 relative to each other, and rising queries with their percentage growth. Google Trends keyword expansion for SEO keyword research, content planning, and spotting breakout search demand early.
Output
Returns two lists: (1) 'top' related queries with a relative interest score from 0 to 100, and (2) 'rising' related queries with a percentage growth value indicating breakout or surging searches — both filtered to the specified keyword, country, and time window.
Example use cases
SEO keyword expansion for blog
“I'm writing a blog post about 'intermittent fasting' targeting US readers — can you pull the top and rising related Google search queries for that keyword in the US so I know what subtopics people are searching for?”
Competitor brand search trend analysis
“Can you check what queries are rising around the keyword 'Notion' in the UK right now? I want to see what people are searching alongside that brand to understand audience intent.”
Market entry research for new country
“We're launching a product around 'solar panels' in Germany — what are the top related Google Trends queries for that keyword in DE over the past 12 months so we can understand the local search landscape?”
