In the series of questions posed to our friend John Mueller on Twitter, a user recently asked the Webmaster Trends Analyst Burundi Email List if it was advisable to change the date of publication of blog posts to the date of last modification. Here is the question initially asked in English on Twitter. If we translate the question into French, it gives: “Would it be acceptable to change the publication date of blog posts to the last modified date?” Because we don’t significantly change all of our posts when we update them, we don’t change the post date. Thus, users only see the date of publication. To improve this, is it a good practice to change the published date to the last modified date? Or is it better to put both dates on the page?

Google would still have access to both dates through metadata, Schema tags, and XML sitemap . What do you think ? ” This is a question that is asked regularly in the SEO community , which makes the answer given by John Mueller particularly eagerly awaited. Basically John replies that if he saw this practice while browsing a site, he would find it quite misleading. Moreover, if he saw this while browsing, he would wonder if he can really trust the other content on the site … with the fear of being trapped by the date displayed. That’s not how he views how trust is built. The tweeters then react with an additional question below. By asking if the solution was to display the two dates: that of the original publication and that of the last modification.

John Mueller’s response

To which John replied that it was advisable to just keep the date that the content was thoroughly updated. The question here relates to the date displayed to the Internet user. In this case, it makes complete sense to be transparent is to display the original publication date. On the other hand, if your content has been updated significantly, it is highly recommended to display only the date of this last modification to consolidate the confidence that your reader will have when reading your article. At the same time, it is quite possible to enter the two dates, the date of publication and the last modification, in the structured data tags of the article. In order to provide as much information as possible to search engines.

Our opinion

ComApril 11, 2020 at 6 h 36 min My own preference is not to change the dates of the articles. But of course, which path you choose is up to you. Whichever strategy you choose, you must remember that not all articles are worth updating. The best types of content for bringing more life are those that are persistent – content that is just as relevant now as it was when you first posted it. The content should also be detailed enough that it resonated with your audience when it was first posted, and there should be enough new and useful information on this topic to add value without derailing the topic of your original article. .
