Whitney,
Good morning.
Sitemaps are created automatically upon indexing of pages.
You can find them in YOAST settings.
As far a pop ups, what is the URL for this page?
Never mind, I see it is this one. 
https://cliffsideskinandlaser.com/ 

Isaac follow up im seeing a few 404s when i google things like dermal fillers in their area for example 

https://cliffsideskinandlaser.com/filler/

Isaac  what is this issue called? it happened to health first too. How would i describe this ? indexing? 

Whitney, there is no real technical name for this... 
They are referred to as 404's, 303's or Broken links... 

whitney.zelig@gmail.com - 

I already took care of the popups and update the URLs in display and success page settings just after making the website LIVE.

For the broken links issue. Did we create the sheet that has all URLs on the old and new website side by side?
If yes. Please share the link.
If not. Then we need to find the old URLs from google search and create a redirection for all of them to the new links.

I have now created a 301 redirection rule for /fillers/ to /dermal-fillers/

I don't think we did that Isaac  but they really didn't have many pages on the old website

whitney.zelig@gmail.com - OK. I will check on google to check if any indexed links from their old website need redirection.

whitney.zelig@gmail.com -

I just checked on Google using site:cliffsideskinandlaser.com. Couldn't find any 404 links except for the PRP page https://cliffsideskinandlaser.com/prp/.

Should I go ahead and create a 301 redirect for this page to here https://cliffsideskinandlaser.com/plasma-treatment/ ?

Good morning Isaac  
Thank you for looking into the 404's. 
Nice work. 
I do not think you should 301 that PRP page as it may lead to Google thinking there is PRP on the site. If we are not running any ads to this site then it can be done. 

Isaac  
I am seeing these  3 pages coming up as 404's

https://cliffsideskinandlaser.com/2019/11/01/is-your-acne-rosacea/
https://cliffsideskinandlaser.com/jason-chouake/
https://cliffsideskinandlaser.com/2020/01/16/can-micro-needling-help-me-eliminate-acne-scars/

---
I am also seeing this page marked as no Index.. 

https://cliffsideskinandlaser.com/test-default-page/
shouldn't we remove it already?

Hector  

Good Morning man.

I agree.

The above links seem to be of blog posts and not pages. I will go ahead and check them. Thank you for finding them.

Couldn't find this page on the website. Where are you seeing it? If you are seeing it on google search results then it may exist on the client's old website.

Isaac, yes that page is from their old site. https://cliffsideskinandlaser.com/test-default-page/

So what do you suggest we do with it to avoid having it come up as 404 or an issue?

Hector -

I have now set up 301 for all the above 404 blog posts to their new URLs.

For the test page.
https://cliffsideskinandlaser.com/test-default-page/

I have redirected it to the homepage.

Good morning Isaac  
Awesome work!
This is why you ROCK so much Isaac. 
Thank you. 

Good Morning Hector .

You rock too hawk eye.
