I'm kinda new to WordPress and im not exactly sure how to add a HTML file or Meta tag. I tried the webmaster tools and it gives me a 404 header error, I don't know what im doing wrong. I don't know where to put it and I wanted to make it private so only Google could find it, so I did it on a private page and its giving me that error. Can someone help me on how I can get a meta tag or HTML file on my blog without others seeing it if theirs a way? If there is no way, can you explain how I can just get it on my blog?
This is kind of off-topic, but people were telling me about page rank, im not sure what that is and if someone could give me a brief explanation that would be great.
Thank you.
