And avoid language that embeds a timestamp (such as \u201cearlier this year,\u201d \u201clast month,\u201d \u201cin&nbsp;2025\u201d).<\/p>\n<p>If the piece is genuinely evergreen, it should feel accurate and relevant two years from&nbsp;now.<\/p>\n<p>Note that this isn\u2019t a hard rule. If freshness is part of your angle (a \u201cbest of\u201d list, a data-driven roundup, an annual update), date signals are appropriate.
