When I do a speed test of one of my blog posts, it mentioned Location: line 651 has Avoid document.write(). How do i locate or find this particular line 651?
Right click then "View page source". When it opens you should see the number of lines of the page (on the left). I am thinking that's what it's talking about.
You can do it from google chrome - In Google Chrome -> Right Click on page --> click on Inspect You can use keyboard keys --> Ctrl+Shift+I
