What happens when you replace a page with a new version that has the same URL?

a new page template was created the plan is to publish the new page (which has the same URL as before) to web and delete the old page that has the URL ,  will that have an SEO implications ?

Hi

The seo implications can be significant.

The first step is to audit - search console probably easiest the organic traffic hitting that exact page.  The value of the page determines the content changes you may consider.

Thus if a page is ranking very well for a high-value target then the changes we recommend would be minimal, primarily CX focussed - enhance value. Enjoy no duplication, and not over optimised.

If the page is a poor performer with limited or no organic traffic, then there is little to no risk in a full content change.  If that is the case, do whatever you like... to improve the value of the page.  The only element to monitor is internal links from that page, again measure impact and audit.

Hope that helps.

I'm assuming that since you're keeping the URL, the content subject matter will be on the same? If not, I feel you would suffer a drop in PA. Regardless, as Gaston has pointed out, Google will at some point releases that page & may alter its rankings in the SERPs.

Hi there,

Replacing a page without changing its URL is entirely normal. It's just updating its content :).
That said, I wouldn't remove the old page from google before updating it. Just update its content, template or whatever you are going to change, and that's it.

What could change in an SEO perspective? Google will recognize that it's a different page and will re-assess whether it's worth to be ranking on the same place and keywords as before. 
A simple example would be when the updated page doesn't have anymore one of the primary keyword stated in its content, Title, and headings. Google will understand that you don't consider that page to be relevant for that keyword.

Hope it helps.
Best luck,
Gaston
