Because a brand-new URL starts from zero on every signal that actually took time to accumulate, backlinks, click history, and the general trust and relevance a search engine builds up for a page over repeated crawls and repeated appearances in results, while an evergreen URL, updated in place each year, carries all of that accumulated signal forward into the next season. Creating “Black Friday Deals 2025,” then abandoning it for a fresh “Black Friday Deals 2026” URL the following year, forces the new page to rebuild authority from nothing at exactly the moment, the run-up to the seasonal event, when ranking well matters most.
The mechanism: what actually gets lost in the reset
Backlinks are the clearest casualty. If external sites, roundup articles, deal-aggregator pages, social shares, linked to last year’s specific dated URL, those links stay pointed at that now-abandoned page. A new URL for this year has none of those links unless every single linking site can be identified and asked to update their link, which almost never happens comprehensively in practice. Even with a 301 redirect from the old URL to the new one, redirects can pass along a meaningful portion of accumulated signal, but Google’s own guidance on redirects has been consistent that a redirect is a substitute for the original URL remaining in place and continuously building signal, not a fully lossless transfer, and repeatedly redirecting a chain of abandoned annual URLs each year compounds whatever dilution occurs at each hop.
Click and engagement history is a second loss. A URL that has existed across multiple seasonal cycles has accumulated a track record, in Google’s own systems, of being a page users have historically found relevant enough to click and engage with for that query pattern. A brand-new URL has no such history yet; whatever trust or relevance signal that click history represented has to be rebuilt through fresh user interactions, and rebuilding takes time, time that directly overlaps with the narrow seasonal window when the page needs to already be performing well.
Indexing trust and crawl familiarity is the third, less visible factor. Google’s systems have effectively been evaluating the same evergreen URL for years by the time a third or fourth seasonal cycle rolls around, it’s a known, established entity with an established pattern of legitimate content updates. A new URL each year is, from Google’s perspective, a brand-new page requiring fresh discovery, fresh crawling, and fresh evaluation, none of which happens instantly, and all of which can lag behind the narrow window during which the content is actually relevant.
Why the evergreen approach avoids all three losses
An evergreen seasonal URL, one stable URL (say, /black-friday-deals/ rather than a year-stamped variant) that gets its content substantively refreshed each year ahead of the relevant season, keeps all of the accumulated backlinks, click history, and indexing trust intact, because it’s literally the same URL continuously being re-evaluated, not a new entity starting over. When the next seasonal cycle approaches, Google already has an established relevance and trust baseline for that URL and that query pattern, so the updated content can begin re-ranking well much faster than a brand-new page could, since there’s no rebuilding-from-zero step required.
This aligns with Google’s general, long-standing guidance around preserving URLs and using redirects deliberately rather than routinely, the consistent theme across Google’s Search Central documentation on site migrations and URL changes is that unnecessary URL churn creates real risk to accumulated signals, and that maintaining a stable URL where the underlying content can legitimately be updated in place is preferable to generating new URLs for what is conceptually the same recurring content.
What to avoid claiming
There’s no verifiable, Google-published specific percentage for how much traffic or ranking a site loses by creating a new URL each year instead of maintaining one evergreen URL; that figure isn’t something Google has disclosed or that’s independently measurable across sites in a generalizable way, and any specific number attached to this claim in industry content should be treated as invented rather than documented.
A common objection: doesn’t a dated URL feel more relevant to a searcher?
A reasonable-sounding argument for the yearly-URL approach is that a URL or title explicitly labeled “2026” might feel more trustworthy or current to a searcher scanning results than a generic evergreen URL with no year attached, avoiding any appearance of showing outdated deals. This is a real UX consideration, but it’s solvable within the evergreen approach rather than requiring a new URL each year: the page’s visible title, headline, and on-page content can still prominently reference the current year and clearly state when it was last updated, giving searchers the same currency signal, while the underlying URL itself remains stable. The year-in-title/content approach captures the perceived-freshness benefit without sacrificing the accumulated URL-level signal a genuinely new URL would forfeit. It’s also worth noting that visible on-page dates and titles are what a searcher actually reads and evaluates for trust in the moment, the URL string itself is rarely something an average searcher scrutinizes closely enough for it to be the deciding factor in click-through, so there’s little UX cost to keeping the URL stable while updating what’s visibly displayed.
What migrating from a yearly-URL pattern to an evergreen one looks like
For a site that’s already built up several years of dated seasonal URLs (a /black-friday-2023/, /black-friday-2024/, /black-friday-2025/ pattern, for example) and wants to correct course, the migration itself needs care to avoid repeating the same signal-loss problem in reverse. Rather than abandoning all the old URLs at once, the more reliable approach designates one evergreen URL going forward (either promoting the strongest-performing historical year’s URL to serve as the permanent evergreen page, or establishing a clean new evergreen URL if none of the historical ones are suitable), then 301 redirecting every prior year’s dated URL to that single evergreen destination, consolidating whatever accumulated signal each of those older URLs still carries into the one page that will represent the topic going forward. From that point on, the discipline is simply never creating a new dated URL again for that recurring topic, updating the one evergreen URL’s content each cycle instead.
Practical implication: the evergreen refresh workflow
Maintain one canonical URL for the recurring seasonal topic. Each year, well ahead of the relevant season, substantively update the content, refreshed deal information, updated dates, updated details, rather than treating the update as cosmetic, and update the page’s structured data and visible dates to reflect the genuine refresh. If a dated URL already exists from a prior year and a switch to an evergreen structure is being made now, 301 redirect the old dated URL(s) to the new evergreen URL once, rather than creating a fresh URL again next year, and keep that redirect and canonical URL stable going forward so every subsequent season continues building on the same accumulated foundation instead of resetting it.
