Someone asks whether there is enough search demand around a product line to justify a content programme. The answer needs a number, and it needs it today.
Filtering to the theme
Take the full keyword export and keep only the rows containing the product term and its common synonyms. The surviving set is the addressable demand for that theme.
Summing volume, with a caveat
Total the volume across the filtered set for a headline figure, but present it as a ceiling rather than a forecast. Nobody captures all of it, and a proposal built on the assumption that they will is a proposal that fails.
Filter for intent as well as topic
Within the theme, filtering again for commercial modifiers — buy, price, best, vs — separates the terms likely to convert from the ones likely to inform. Those two piles justify different content and different expectations.
