How do I add a website link to my tumblr?

[Kassidey]

Well I finally got tumblr and I'm in the process of setting up my blog. I want to add some website links in the top bar but I have no idea how. I've watched a ton of videos and read a bunch of tutorials but they're all pretty old and I guess tumblr changed? They all tell me to go to customize, pages then change it to redirect layout. I don't have this option. I only have a choice of "standard layout" and "custom layout". I would like to add links to Peta and the World Wildlife Fund. If anybody could take the time to walk me through step by step I would really appreciate it!

Note: I'm not looking to link twitter or instagram. Just actual websites. I want the link to redirect to the website. Thank you!

Go to your theme's html by clicking the "edit html" button in your settings customization page.
- next look for the section that looks like this:
<div id="meta-column">
Under this you'll see the navigation section with your archive, subscribe, and contact links. If you want to add a link under the contact link add the following.
<li><a href="URL you want to link it to">New Link Name</a></li>
Replace the "URL you want to link it to" with the actual url of the link you want the link to go to and replace the "new link name" with what you want to call the link.

Before the link add "http://" so it looks like this <a href="http://yoursite.com/"> LINK </a>
