Is Content Updation is necessary

[SEO.Ninja]

Yes content updation is necessary but it depends on types of keyword searches most likely to require fresh content like- Recent events or hot topics, Frequent updates. Google measures all of your dоcuments for freshness, then scores each page according to the type of search query.

Without updates, your site is just digital decay. Google's crawlers see it as a low-quality footprint. You'll lose crawl budget, get hit by helpful content updates, and watch your DR plummet. Keep it stale and disappear.
