Background of Development: The Growing Risk of 'Content Expiration'
Content accumulated by companies on their owned media and corporate websites is a crucial marketing asset. However, as the number of pages increases, the risk of 'outdated information remaining as is' proportionally rises.
Specifically, the following problems are occurring:
- Information from before legal or institutional revisions continues to be published despite the revisions.
- Data from several years ago or information about discontinued products remains, misleading viewers.
- It is difficult to regularly check hundreds to thousands of pages manually.
Such 'information expiration' can lead to damage to a company's credibility and brand value. SiteEngine has engaged with many companies facing this challenge through its content creation support. Based on this experience, the company embarked on developing a tool to automate the management of information freshness.
