This is because a brand-new piece of content takes much longer to settle on the results page of search engines (SERP) and earn authority, but you can refresh a piece of material and reap the advantages instantly. Not only will your appropriate amount rank higher on the SERPs, doubling the levels of visits and leads, but upgrading a current piece of content takes far less time and resources than creating a completely new post. The ultimate step is to delete any obsolete information that is no longer relevant to your target audience.
