Ranked on keyword discovery, with intent qualification as the tie-breaker.
A good discovery tool hands you a thousand keyword ideas in seconds. That is valuable at the start. The problem comes next: out of those thousand, how many truly deserve your budget? Sorting by hand takes hours and runs on gut feel.
Should I Bid handles the second half of the work. You import the list from Semrush or Ahrefs, and each keyword gets a verdict and a score. Quantity comes from the suite, sorting quality comes from Should I Bid.
Vision, Should I Bid’s discovery module, starts from what you sell: a product or a URL. It pulls keyword ideas, sorts them by type (brand, generic, questions), deduplicates, and launches the analysis. Handy when you do not have a list yet, or to complement a suite’s list with angles close to your offer.
Yes. That is the main use case: you discover elsewhere, then qualify in Should I Bid to keep only the keywords with real intent before building your campaigns.
Not with Should I Bid: pricing is per credit, no forced subscription. You pay for the keywords you analyze, which fits research done in waves.
