I didn’t use plugin I only search it online and saw that I can do it manually using theme editor. So just follow these steps!
- Go to appearance
- scroll down to editor
- in the right side search for header.php
- You found it? great! Click on it
- Scroll down and search for this: <head>.
- Past the code right after it. ( look at the screenshot)
- and finally, Click Update file. that’s it.
