To discover new keywords in bulk, Semrush and Ahrefs stay the references. But discovering is not enough: you still have to qualify. The most effective combination is a discovery tool for quantity, then Should I Bid to keep only the keywords with real buying intent. Used alongside, Should I Bid keeps you from paying for high-volume, low-relevance keywords.
| Rank | Tool | Strengths | Best for | Pricing |
|---|---|---|---|---|

| 2 | Semrush | Massive keyword database, suggestions and related questions. | Large-scale discovery. | Subscription (amount under “Verified prices”). |
| 3 | Ahrefs | Very complete Keyword Explorer, multi-country data. | In-depth research and SEO. | Subscription (amount under “Verified prices”). |
| 4 | Google Keyword Planner | Official Google suggestions and volumes, free. | Getting started with no tool budget. | Free. |
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.
