Let's say, for example, you're researching the keyword "how to start a blog" for an article you want to create. "Blog" can mean a blog post or the blog website itself, and what a searcher's intent is behind that keyword will influence the direction of your article. Does the searcher want to learn how to start an individual blog post? Or do they want to know how to actually launch a website domain for the purposes of blogging? If your content strategy is only targeting people interested in the latter, you'll need to make sure of the keyword's intent before committing to it.
NOTE, in 2020, the HTML title element you choose for your page, may not be what Google chooses to include in your SERP snippet. The search snippet title and description is very much QUERY & DEVICE dependent these days. Google often chooses what it thinks is the most relevant title for your search snippet, and it can use information from your page, or in links to that page, to create a very different SERP snippet title.
QUOTE: “You always need textual content on-page, regardless of what other kinds of content you might have. If you’re a video-hosting site, you still need things like titles, headings, text, links, etc. The same goes for audio-hosting sites. Make it easy for search engines to understand your content & how it’s relevant to users, and they’ll be able to send you relevant traffic. If you make it hard for search engines to figure out what your pages are about, it would be normal for them to struggle to figure out how your site is relevant for users.” John Mueller, Google 2019
