If Google doesn’t show the search volume for a long-tail keyword, don’t worry — there are still ways to get a good idea of its popularity.
You can use tools like Ahrefs, SEMrush, Ubersuggest, or Keywords Everywhere. They often show an estimate, even if it’s small. If it says “zero,” it might still get some searches — just not enough to show up in the data.
You can also check your own Google Search Console to see if that phrase is already bringing in clicks or impressions. Another simple trick is to type it into Google and look at the autocomplete suggestions or related searches at the bottom — those are based on real searches.
Also, check places like Reddit or Quora to see how people naturally talk about the topic. Even without exact numbers, long-tail keywords can still bring in really targeted traffic.
