Google shows how-to results for a “what is” query because it serves what searchers actually want behind the words, and click data has revealed that many people typing “what is X” really intend to do X, so the SERP shifts to instructional content to match the behavior rather than the grammar. The displayed intent reflects how searchers behave, not how their phrase parses. You can see this play out: the wording asks for a definition, but the results lean toward steps and tutorials, because that is what the people behind those words kept clicking.
The mechanism is behavioral feedback. When users search a query, Google watches which results they choose, how long they stay, and whether they come back to try another result. Over millions of searches, that data forms a picture of what genuinely satisfies the query, independent of the literal grammar. If “what is X” searchers consistently bypass dictionary-style definitions and engage with pages that show them how to do X, Google learns that the real intent is procedural, and it reshapes the SERP toward how-to content to serve that learned demand. The behavior overrides the wording.
This happens because grammar is a poor reporter of intent. A phrase like “what is intermittent fasting” looks definitional, but a large share of people asking it want to know how to actually do it, not just a one-line meaning. The “what is” frame is often just how someone opens an inquiry they intend to act on. Google, reading behavior rather than syntax, sees past the phrasing to the underlying job and serves the content that gets that job done.
The takeaway for anyone targeting such a query is that the words on the page do not get to decide the intent; the searchers do, and the SERP records their verdict. A query that grammatically asks for a definition may, in practice, demand a how-to, and a page that delivers only the definition will lose to one that delivers the steps, no matter how well it defines.
So when you target a “what is” query, do not trust the grammar to tell you what to write. Search it, read what content type Google is actually rewarding in the results, and build that, because the SERP’s shown intent reflects real behavior and that is the standard your page will be judged against.
