Update Old Post or Make New Post Better for SEO?

Hey i was just looking for some opinions on the topic.

Do you think its better or faster for SEO to update an old post made months ago with a new article, tags etc, or would it better or faster for SEO to just make a completely new post with the article, new tags etc.?

For a time sensitive document it doesn't make sense to updated.

For a piece of evergreen content, then putting in updates on the document makes sense.

Im basically trying to rank for more keywords on a given article or post thats already been indexed a couple months back.

So im trying updating the posts with new content and then resubmitting the sitemap.

Anyone else got an opinion?

up date is better
you already have the post indexed and backlinks to it

New post is always better.

If you are editing an old post, the URL is always going to be the same. And Google will be notified about the same URL (when used indexing service) which it already crawled months back.

But when you are making a new post, the post will have a new URL. Google will be crawling the content for the first time and it will identify the post as update on the site. Websites which are updated frequently with meaningful content gets more weightage as far as SEO is concerned.

I think that there is no need for you to do any updating. If your article has some google love already for some of the keywords, and you want to include new keywords that are similar to the present ones, you could just add new backlinks with anchor text of the new keywords you want to target.

It is true that google loves site that update content regularly but if he writes a brand new piece of text, he will get a new url but his position for the keyword he now targets willl be who knows where.

If you already ranking then no need to updates.

Rather than changing the entire post, you could consider re-optimising it (switching the keyword to another similar keyword, updating tags, spell checking, etcetera), especially if the post is no longer bringing in as much traffic as it used to. That way, when you do apply the changes to your post, the current inbound links that are pointing to your post will not be misleading and you can prevent the loss of those inbound links as well as save other webmasters the time of having to remove the link.

In the event that the article is ranking just fine, it's still a good idea to go back and update the article with minor changes (e.g., spelling and grammar) both to improve the quality of the article for your readers and to show the web crawlers that the website is still active.

Yeah, I would go on re-optimizing the old post but leave the published date as is. Then create another quality post related to the entry you just re-optimized and link to it.
