Keyword Checker · AI niche verdicts

From a keyword list to niches a small site can win

Paste keywords from Keyword Explorer, import an Ahrefs or Semrush export, or your own list. Niche Miner groups them into niches, filters out what a small site can't win, asks AI for a verdict with the reason, and checks which exact-match domains are still free.

How to use it best

How to use Keyword Checker best: a real Niche Miner screenshot with numbered steps
  1. Import from Keyword Explorer, an Ahrefs or Semrush export, or your own list.
  2. Keep Only micro-site niches, pick an intent (Tool, Downloadable…) and sort by niche score.
  3. Run the AI on your own key (Gemini is free) and read the reason, not just the score.
  4. Pick a domain marked free: .com first, then the country ending. Copy the keywords and build.

1. Filters cut the list in seconds

Niche Sheet mode builds niche cards straight from your list, with their total volume, with no AI and no cost. Then narrow it down with filters that know what a micro site needs: micro-site, intent and religious filters, rates & prices, rising keywords, words to include or leave out, a CPC range, and saved presets.

2. An AI verdict on every niche

Each niche gets Go for it, Maybe or Skip, with the reason, the competition and how it would earn. The AI runs on your own key: a free Google Gemini key is enough to start, and Pro AI / Pro AI+ include the AI if you'd rather not deal with keys.

Questions

Which AI should I use?

Gemini is free and enough to start. For bulk checking, an OpenAI key (GPT-4o mini) is cheap and fast. Claude, DeepSeek and Groq work too.

Can I share a niche without giving it away?

Yes: turn any card into a picture for Facebook with the niche name hidden and your referral code on it.
