Should I add an updated date or change the published date for SEO improvement?

I’m working on improving my site’s SEO, which has significantly declined. From my research, updating older blogs with new information and including an updated date is recommended.

Since my site is hosted on Shopify and currently displays the published date, should I add an updated date, or should I change the published date?

I’ve been reading mixed things. Some say you should adjust published dates if I write something new or change something significantly. Others say to leave the original published date intact can help maintain and context and credibility.

I figured this out on my own! YAYAYYA MEEE

Go to Online Store > The three dots on your Current theme > Edit Code > Search for article-template.liquid

Within the first 10 lines look for:

{% if section.settings.blog_show_date %}

{{ article.published_at | time_tag: format: ‘date’ }}

{% endif %}

and updated with:

{% if section.settings.blog_show_date %}

Published: {{ article.published_at | time_tag: format: ‘date’ }}

{% if article.updated_at %}
Updated: {{ article.updated_at | time_tag: format: ‘date’ }}
{% endif %}

{% endif %}

I added Published: and Updated: to the dates.

Enjoy!!
