The same applies to new information, blogs, customer testimonials, and so on. Including dates is obviously better—it’s common sense.
However…
That’s true only for those who can update content frequently. If updates aren’t feasible, it’s preferable to omit dates altogether.
If the latest post in the “latest information” section is from three years ago, it can significantly damage the website’s or even the company’s credibility. For a company, it might prompt people to question, “Are they still active?”
The same principle applies to blogs. If a blog hasn’t been updated in three years, visitors are less likely to engage with it. Similarly, outdated customer testimonials might raise doubts like, “Has no one been satisfied in all this time?”
In such cases, it might be wiser to avoid displaying dates.
Another scenario arises when the person responsible for a blog leaves and can no longer update it. In such instances, it’s advisable to hide all dates, including past articles. While having dates is ideal, even without them, maintaining the blog as a repository of information can still yield positive SEO benefits.
Dates carry weight. It’s crucial to make a clear decision on whether to include them based on your specific circumstances.
