I’m hoping you can give me some advice:
I created a blog post you can see here: https://www.reyrrodriguez.com/seo-services-worth-it/
I added videos by embedding the YouTube player. I realized the page became a lot slower. So I tried to fix it by following this tutorial. https://www.labnol.org/internet/light-youtube-embeds/27941/
I added the script part using google tag manager using custom HTML tag: http://prntscr.com/py9xk7
Then I added the css under themes, customize, additional css: http://prntscr.com/py9yve
The problem is, as you can see near the bottom of the page under the footer the code shows: http://prntscr.com/py9zic
I tried to run a system backup using siteground which is my hosting service. But it did not work to revert the change.
Can you give me some tips how I can complete this correctly: https://www.labnol.org/internet/light-youtube-embeds/27941/
And remove the code at the bottom?
I would really appreciate. -Rey
PS: Before completing the system back up I paused the tag within tag manager and also tried to delete it. But the code at the bottom never went away.
