If the page title and first sentence of text are well-written, concise, and optimized for SEO, that might be OK.
If you don’t customize your meta title and description, Google will automatically display the web page’s full title and the first few lines of text that appear on it (if any) in search results. If the page title and first sentence of text are well-written, concise, and optimized for SEO, that might be OK. But if you really want to get your target audience’s attention and improve the chances of a click-through in search results, you should give it a little more attention.
