I thought it would be hard. I didn't want to tamper with my source code because I'm not a coder. I tried uploading HTML files into file manager, but this didn't work because my HTML files were empty.
EASY ALTERNATIVE: Just drop one line of code below "head" in your source code. This is easier than it sounds:
In wordpress, go to 'design' -> 'theme editor' -> 'header'
In blogger, just go to 'layout' -> 'edit html'
Having done this, I can now verify that this post was crawled :)
